Best Rainbow Cookies Recipes

RAINBOW COOKIES

Steps:

• You'll need three 9-by-12-inch jelly roll pans or rimmed baking sheets to make these layered cookies.
• Prep the pans: Position racks in the upper and lower thirds of the oven; preheat to 350 degrees F. Butter and flour three 9-by-12-inch jelly roll pans or rimmed baking sheets and line with parchment paper.
• Make the batter: Combine the almond paste and 3/4 cup plus 2 tablespoons sugar in a stand mixer fitted with the paddle attachment. Mix on medium speed until the mixture is in fine crumbles. Beat in 2 1/2 sticks butter, a few pieces at a time, until well combined. Beat in the egg yolks, one at a time, until smooth.
• Sift 2 cups flour onto a sheet of parchment and sprinkle the salt on top; add to the mixer bowl and beat until just combined.
• In a clean bowl, whisk the egg whites until foamy; while whisking, slowly add the remaining 2 tablespoons sugar and whisk until firm peaks form (or use a hand mixer). Fold about one-third of the egg white mixture into the batter with a rubber spatula, then gently fold in the rest. The batter should be fluffy.
• Color the batter: Divide the batter evenly among 3 bowls. Stir enough red food coloring into 1 bowl to make a deep salmon color. Stir enough green food coloring into another bowl to make a medium green color. Leave the third bowl uncolored.
• Bake the layers: Transfer the batter to the prepared pans (one pan for each color). Dip an offset spatula in water and spread the batter to the edge of each pan, smoothing the tops. Bake, switching the position of the pans halfway through, until the cakes are cooked through and just beginning to brown around the edges, 8 to 10 minutes. Let cool completely in the pans on wire racks.
• Assemble the layers: Spread half of the jam evenly over the green cake layer almost all the way to the edges. Unmold the plain cake layer by inverting it onto another pan or cutting board; peel off the parchment.
• Carefully slide the plain layer onto the green layer (use a wide offset spatula to help you, if necessary). Spread the remaining jam on top of the plain layer. Unmold the red cake layer and slide it onto the plain layer.
• Cover the cake with plastic wrap and top with one of the empty pans; place several heavy cans on top to weigh down the layers. Refrigerate at least 4 hours or overnight.
• Unmold the cake: Remove the cans and plastic wrap. Place a cutting board on top of the cake and flip to unmold it onto the cutting board. Remove the parchment from the top of the green layer.
• Trim the cake: Trim the sides with a knife to make straight edges. Spray a wire rack with cooking spray; set the rack over a baking sheet. Carefully slide the cake onto the rack, using a wide offset spatula to help you, if necessary.
• Cover in chocolate: Melt the chocolate in a heatproof bowl set over a pan of simmering water; pour over the cake. Dip an offset spatula in the hot water and smooth the top and sides. Let set slightly. Scrape wavy lines into the chocolate with a fork; let cool a few more minutes until the chocolate is mostly set but still slightly tacky.
• Cut into pieces: Slide the cake back onto the cutting board. Slice crosswise into 6 strips, then cut each strip into 8 rectangular pieces. For clean edges, dip the knife in warm water and wipe it with a cloth between cuts. Store in an airtight container at room temperature for up to 1 week.
• If the lines in the chocolate don't hold their shape, let the chocolate set a little longer and try again.

RAINBOW COOKIES

Steps:

• Preheat oven to 350 degrees F (175 degrees C). Line three 9x13 inch baking pans with parchment paper.

SLICE AND BAKE RAINBOW COOKIES RECIPE BY TASTY

Steps:

• Using a hand mixer or standing mixer, beat butter until creamy.
• Add powdered sugar and beat until combined. Add the eggs, vanilla, and salt. Beat until well combined.
• Gradually, add the flour until dough is moist and holds together, but doesn't stick to your hands.
• Place dough on a cutting board and form into a ball. Cut in half, then cover one half with plastic wrap and set aside.
• Divide the other half into 6 pieces. The outer layers of the rainbow will need a little bit more dough, so make two of them slightly larger than the others.
• Dye the dough with food coloring by placing a ¼ teaspoon of dye on the ball of dough and kneading it until it is one solid color. Gloves optional but suggested.
• Starting with purple, roll the dough into a log about 6-8 inches (15-20 cm) long. This will be the center of the rainbow.
• Next, roll out the blue dough with a rolling pin until it's about ¼ inch (6 mm) thick, slightly longer than the purple, and wide enough to wrap around the purple dough. Repeat with the green, yellow, orange, and red doughs. The further away from the purple you get, the wider the dough needs to be to go around the previous color, making the red dough the widest.
• Wrap the blue dough around the purple, pinching together any cracks that form, cutting off any excess dough. Repeat with the rest of the colors.
• Wrap in plastic wrap and chill for 30 minutes.
• Once chilled, remove the plastic wrap, and cut the dough in half to make 2 rainbow shapes. Set aside.
• Cut the reserved dough in half, roll out to ¼-inch (6 mm) thickness, and make it slightly longer than the rainbow log.
• Place the rainbow dough in the center and wrap the plain dough around it, again, pinching together any cracks and smoothing out the surface.
• Repeat with the other halves. Wrap with plastic wrap and chill for another 30 minutes.
• Preheat oven to 350˚F (180˚C).
• Once chilled, remove the plastic wrap. Slice cookies about ½-inch (1 cm) thick and place on a parchment paper-lined baking sheet.
• Bake for 20 minutes or until the bottom has browned slightly.
• Cool on a cooling rack.
• Enjoy!

SLICE-AND-BAKE ITALIAN RAINBOW COOKIES

Steps:

• For the cookies: Whisk together the flour, baking powder and salt in a medium bowl until combined.
• Beat the butter, granulated sugar and confectioners' sugar in a large bowl with an electric mixer on medium-high speed until light and fluffy, about 2 minutes. Beat in the egg yolks and almond extract until smooth, scraping down the sides of the bowl with a rubber spatula, as needed. Reduce the mixer speed to medium low and gradually beat in the flour mixture until the dough just comes together.
• Divide the dough into 3 equal pieces and place each in a separate small bowl. With gloved hands or a rubber spatula, use the food coloring to tint one piece red, one yellow and one green. Starting with the green dough on a piece of parchment, shape it into a rectangle that's about 10 inches long and 2 1/2 inches wide, using the parchment and a bench scraper to make the dough as rectangular and even as possible. Repeat with the yellow and red dough on separate sheets of parchment. Using the parchment to help lift the dough, carefully invert the yellow rectangle on top of the green, pressing gently to adhere. Remove and discard the parchment. Finally, use the parchment to carefully lift and invert the red rectangle on top of the yellow, pressing gently to adhere; remove and discard the parchment. Use the bench scraper to even out all the sides. Wrap the entire log of dough in plastic wrap and freeze until firm, about 1 hour, or refrigerate overnight.
• Preheat the oven to 375 degrees F. Line 2 rimmed baking sheets with parchment.
• Trim the ends of the dough log with a sharp knife, then slice crosswise into 3/8-inch-thick rectangles. Arrange about 1 1/2 inches apart on the prepared baking sheets and refrigerate until ready to bake, at least 15 minutes.
• Bake one baking sheet at a time until the cookies are just set around the edges and golden on the bottom, about 15 minutes. Let cool 5 minutes, then transfer the cookies to a wire rack to cool completely.
• For the chocolate icing: Once the cookies have cooled, combine the chocolate, cream and butter in a medium heatproof bowl set over a saucepan of simmering water (do not let the bowl touch the water). Stir with a small silicone spatula until melted and smooth, 2 to 4 minutes. Remove the bowl from the pan and stir in the raspberry extract; let cool 5 minutes.
• Dip each cookie at an angle into the chocolate icing and coat about one-third of the way up, letting any excess drip back into the bowl. Once all the cookies are dipped, wiggle a small offset spatula through the chocolate coating on each to create ripples. Let set, about 35 minutes. The cookies will keep in an airtight container for up to 5 days.

RAINBOW COOKIES

Steps:

• Preheat oven to 350°F and grease 3 (13- by 9-inch) metal baking pans. Line bottom of each with wax paper, letting it extend at 2 opposite ends, and grease paper. Break marzipan paste into small pieces and grind with sugar in food processor until no lumps remain. Transfer to a large bowl and add butter. Beat with an electric mixer until light and fluffy, then add yolks and almond extract and beat well. Beat in flour and salt on low speed. Beat egg whites in another bowl with cleaned beaters until they just hold stiff peaks and stir one third into batter to lighten slightly (batter will still be stiff). Fold in remaining whites thoroughly. Divide dough into thirds (about 1 1/2 cups each). Stir green food coloring into one third and red food coloring into another, leaving one third plain. Spread each dough separately into a pan. (Layers will be thin.)
• Bake layers in batches in middle of oven until just set and beginning to turn golden along edges, 7 to 10 minutes total. Run a knife along edges to loosen from pan, then while still hot, invert a large rack over pan and invert layer onto rack, pulling gently on wax paper overhangs to release if necessary. Peel off wax paper and cool completely.
• Line a large shallow baking pan with wax paper and slide green layer into it. Spread half of jam evenly over green layer and carefully top with plain layer. Spread remaining jam evenly over uncolored layer and carefully top with pink layer (trim edges if necessary). Cover with plastic wrap and weight with a large cutting board or baking pan. Chill at least 3 hours.
• Melt chocolate in a double boiler or a metal bowl set over a pan of barely simmering water. Remove weight and plastic wrap and spread chocolate evenly over top, but not sides, of pink layer. Let stand at room temperature until set, about 1 hour, and cut into small diamonds (12 rows crosswise and 12 diagonal rows).

ITALIAN RAINBOW COOKIES

Steps:

• Arrange 2 racks in the center of the oven and heat to 350 degrees. Make room in your refrigerator for 1 half-sheet pan. Grease 3 (13-by-9-inch) baking pans or quarter-sheet pans with cooking spray or a little oil, then line with parchment or wax paper. (This helps the paper stay in place.) Spray or oil the parchment.
• Combine the flour and salt in a medium bowl. In the bowl of a standing mixer (or with a hand mixer), or in a large bowl if using an electric hand mixer, break up the almond paste using a fork or your fingers. Add butter, sugar, egg yolks and almond extract. Using the paddle attachment, beat on high until light and fluffy, about 5 minutes, scraping down the bowl halfway through. Turn off the mixer, add a third of the flour and salt, then beat on medium-low until just combined. Repeat with another third, scraping down the sides of the bowl as needed, and continue until all the flour is added and incorporated. Transfer batter to a large bowl. Rinse and dry the mixing bowl.
• Add egg whites to the mixing bowl and beat on high speed with the whisk attachment until stiff peaks form, 30 to 45 seconds. Fold the egg whites into the batter until just combined.
• Remove one-third of the batter to one of the prepared pans. Use an offset spatula to evenly spread the batter in the pan all the way to the edges. (This can get a little tricky, but have patience and take your time. The oil on the pan should help hold the paper in place, but if you're having trouble, hold the paper in place with one hand while you spread with the other.) Remove another one-third of the batter to a medium bowl and add a couple drops of green food coloring. Stir until blended, and add more to reach your desired shade. Transfer green batter to a prepared pan and spread evenly. Add a couple drops of red food coloring to the remaining batter, stir to combine, add more as needed, then transfer to the last pan and spread evenly. Firmly tap each pan on the countertop to release air bubbles.
• Bake for 10 to 11 minutes, rotating pans halfway through, until the edges are barely browned, the tops are just set, and a toothpick inserted into the center comes out clean. Immediately slide cakes from the pans onto racks using the parchment paper. Cool completely.
• Using the parchment paper, slide the green cake onto a half-sheet pan. In a small saucepan, heat preserves over medium until loose, then strain through a fine mesh sieve. Spread half of the preserves over the green layer, going all the way to the edge. Carefully flip the uncolored layer on top (use a large offset spatula to help), and remove the parchment paper. Spread with the remaining preserves. Top with the red layer and remove the parchment paper. Cover with plastic wrap and place another rimmed baking sheet on top of the cookies. Transfer to the refrigerator, then top with heavy cans so the weight is evenly distributed. Refrigerate overnight.
• Melt half of the chocolate in a double boiler or in the microwave in 30-second bursts. Using an offset spatula, spread the chocolate on the top and to the edges, then refrigerate until firm, about 30 minutes. Melt the remaining chocolate. Place a piece of parchment or wax paper on a cutting board, then place on top of the cake and invert the cake onto the board. Spread the bottom with the remaining chocolate. Let cool for a few minutes, then use the tines of a fork to draw waves in the chocolate and add sprinkles, if desired. Refrigerate until almost firm, but still slightly soft, about 5 to 10 minutes. (If you wait until the chocolate is fully set, the chocolate will crack when you cut.)
• Run a sharp knife under hot water, dry, then trim the edges and save for snacking. Cut the cake into 1-inch squares, running the knife under hot water and drying between cuts. Return to the refrigerator to set completely. Store in the refrigerator in an airtight container with wax paper between layers. Allow to come to room temperature a bit before serving.

RAINBOW SLICE-AND-BAKE COOKIES

Steps:

• Whisk the flour, baking powder and salt in a medium bowl. Beat the butter, granulated sugar and confectioners' sugar in a large bowl with a mixer on medium-high speed until light and fluffy, about 2 minutes. Beat in the egg yolks and vanilla until smooth. Reduce the mixer speed to medium low and gradually beat in the flour mixture until the dough just comes together.
• Divide the dough into 6 pieces: 2 large pieces (about 7 ounces each), 2 medium pieces (about 5 ounces each) and 2 small pieces (about 3 ounces each).

Remove weight and plastic wrap. Bring to room temperature. Melt chocolate in a double boiler over barely simmering water, stirring until smooth. Remove from heat. Keep chocolate over water. Trim edges of assembled layers with a long serrated knife. Spread half of chocolate in a thin layer on top of cake. Chill, uncovered, until chocolate is firm, about 15 minutes. Cover with another sheet of wax paper and invert cake onto another sheet pan and remove paper. Spread with remaining chocolate. Chill until firm, about 30 minutes. Cut into squares.

VENETIANS - RAINBOW COOKIES

Steps:

• 1. Preheat oven to 350 degrees. Butter a 13 X 9 inch baking pan and line the bottom with parchment/wax paper, leaving a 2 in ch overhang on the ends (easier to remove), butter the paper.
• 2. Beat egg whites until they hold stiff peaks. Add 1/4 cup sugar (a little at a time) beating at high speed until whites hold stiff, slightly glossy peaks. Set aside.
• 3. In another bowl, beat together almond paste and remaining 3/4 cup sugar until well blended, approximately 3 minutes. Add butter and beat until pale and fluffy, another 3 minutes. Add yokes and almond extract and beat until combined well (approx. 2 minutes). Reduce speed to low, then add flour and salt and mix until just combined. Fold egg whites into almond mixture to lighten the mixture.
• 4. Divide batter evenly among 3 bowls. Stir red food coloring in one bowl; green in the other; leaving one bowl uncolored. Pour one bowl/batter into creased baking pan and spread evenly with offset spatula (layer will be about 1/4 inch thick). Bake 8 to 10 minutes until the edges just pick up color - do not overbake. REPEAT WITH REMAINING bowl/batter - Transfer layers to a wire rack to cool.
• 5. When all layers are cool, invert green onto a parchment or wax-paper-lined large baking sheet. Discard paper from layer and spread with half of preserves. Invert white on top of green layer, discarding paper. Spread with remaining preserves. Invert red layer on top of white layer and discard wax or parchment paper.
• 6. Cover with plastic wrap and chill several hours (at least 4 hours). (Recipe calls for you to weight the top down with a heavy object but I stopped doing that and it comes out fine.) Remove weight and plastic wrap. Bring layers to room temperature. Melt chocolate in a double boiler or a metal bowl set over a saucepan of barely simmering water, stirring until smooth. Remove from heat. Keep chocolate over water.
• 7. Trim edges of cake and pour/spread chocolate over the top in a thin layer. Chill, uncovered, until chocolate is firm. OPTIONAL - you can flip the cake over and coat the underside with chocolate as well. Chill again.
• 8. When all is chilled, cut lengthwise into strips, then crosswise. TIP: THE COLDER THESE ARE, THE EASIER TO CUT ... MAKE SURE THEY ARE WELL CHILLED / EVEN SLIGHTLY FROZEN!

RAINBOW COOKIES

Steps:

• Heat oven to 200C/180C fan/gas 6. Mix the butter, sugars, egg yolks and vanilla with a wooden spoon until creamy, then mix in the flour in 2 batches. Stir in the orange zest. Roll the dough into about 22 walnut-size balls and sit on baking sheets. Bake for 15 mins until golden, then leave to cool.
• Meanwhile, mix the icing sugar with enough orange juice to make a thick, runny icing. Dip each biscuit half into the icing, then straight into the sprinkles. Dry on a wire rack.

RAINBOW COOKIES(7 LAYER)

Steps:

• Beat eggs, add melted butter, almond extract, sugar, and flour. (Let the melted butter cool a bit before adding it to the beaten eggs).
• In 3 bowls, evenly divide batter. Leave 1 bowl white, 1 bowl red, and 1 bowl green.
• Place each batter in a very shallow pan-seperately.(I use aluminum pans from Waldbaums. They are the size of a loaf, but not as deep. They come in a package of 3-which is what you need). Bake at 350 for 10-12 minutes- approximately.
• Put red layer on top of wax paper. Spread raspberry preserves on layer. Take white layer, place on top of the red layer and spread preserves. Take the green layer, place it on the white. Spread the melted chocolate chips on the top.
• Place in the freezer, just long enough for the chocolate to harden. When hardend, take out and do the same on the other side.
• Take out carefully and slice into bars. Whole pieces can be frozen and sliced when needed.
• ****NOTES****.
• While the 1st side of the bar is hardening, you can start the whole process over because you will have enough batter and melted chips for a 2nd bar of cookies. ALSO Add some oil to melting chocolate chips to keep it from clumping together (if needed).
