Best Flag Sheet Cake Recipes

FLAG SHEET CAKE

Steps:

• Trim any rough edges from cakes using a serrated knife. Place four strips of parchment paper around the perimeter of a serving platter. Place first layer, bottom side up, on serving platter. Using an offset spatula, spread cake with 2 1/2 cups frosting. Top with remaining layer, bottom side up. Spread entire cake with 5 1/2 cups frosting. Place remaining frosting in a large pastry bag fitted with a star tip (such as Ateco #35). Remove parchment paper strips.
• Using the tip of a toothpick, outline the shape of a flag on the cake. Fill the upper left-hand corner with a single layer of blueberries. Place one row of raspberries across upper edge of cake to form first red stripe. Pipe one row of stars just below raspberries to form first white stripe. Repeat process with remaining raspberries and frosting until you have 7 red and 6 white stripes.

AMERICAN FLAG SHEET CAKE

Steps:

• Preheat oven to 350 degrees Fahrenheit. Grease a 13" x 18" rimmed baking sheet - spray with your favorite non-stick spray or wipe down with a bit of oil.
• In a large bowl, sift together the flour, sugar, cocoa powder, baking soda, and salt. Stir with a whisk or a wooden spoon to combine.
• Using the back of a wooden spoon, make three indents in the flour mixture. Into one indent, pour the vanilla. Into the second, pour the vinegar. Into the third, add the oil. Pour the water over the top. Stir well until combined.
• Spread the batter in the baking sheet and, using an offset spatula, spread the batter to the edges of the pan, making it as level as possible. Bake for 14-17 minutes; until the sides have pulled away from the edge a bit and a toothpick inserted into the center comes out clean. Pull the cake out of the oven and set on a wire rack to cool completely.
• While the cake cools, make the buttercream frosting. Using a stand mixer or hand mixer, whip the butter until smooth. Add a cup of powdered sugar and mix in at low speed. Add remaining powdered sugar, a cup at a time, and mix until smooth. Add the vanilla and the milk. Mix until smooth and an easily spreadable consistency. If too thick, add more milk - just a teaspoon at a time, as it thins out easily. If too thin, add more powdered sugar.
• Once the cake is completely cool, frost it with the buttercream - simply smooth it all over the top in a thin, even layer.
• Now, it's time to decorate! Visually divide the cake into thirds and, in the top third, fill in with rows of blueberries. Add rows of halved strawberries next; the amount of stripes depends on the size of your strawberries, so just eyeball it, and if you need to adjust the berries, you can use the tip of the offset spatula or the tip of a spoon to create stripes in between the rows of berries.
• Serve as soon as possible; it can be made ahead of time, but the strawberries will probably start to leak after awhile, so keep that in mind.

FOURTH OF JULY OR FRENCH FLAG WHITE SHEET CAKE WITH RASPBERRIES

Steps:

• Place the rack in the middle of the oven and preheat it to 375°F Spritz a 9x13 shiny aluminum baking pan with Pam or Baker's Joy. Place the unbroken eggs in a bowl of hot tap water.
• Beat the butter and sugar in the stand mixer until pale and fluffy, about 3 minutes. Add the eggs, one at a time, then the vanilla, and beat until thoroughly mixed, about 5 minutes. Sift the flour, baking powder, and salt onto a sheet of wax paper. Spoon in the flour in thirds, alternately with milk. Mix just until the batter is smooth.
• Pour the batter in the prepared pan and bake until the cake begins to pull away from the sides and a wooden pick comes out clean, 18 to 20 minutes. Cool on a rack.
• Frosting:.
• While the cake is cooling, place the butter in the mixer bowl and cream until soft, adding the egg yolk, salt and vanilla. With the mixer on low speed, add the confectioners' sugar and milk (or cream) alternatively until you have a smooth mixture. Refrigerate until the cake is cool.
• Assemble the cake. Invert the cake onto a large serving platter. Smooth the frosting over the top and sides, using an offset spatula. Make a design on top, using the berries to create a flag. Use both raspberries and blueberries in the upper left quadrant to represent the "starts", then make the "bars" by making alternating horizontal stripes of raspberries and blueberries. Finish by alternating whole blueberries and raspberries all around the base of the cake.
