Yield Makes about 2 1/2 dozen

Number Of Ingredients 12

1/4 cup (1/2 stick) unsalted butter, softened
3/4 cup confectioners' sugar
2 large egg whites
1/2 teaspoon pure vanilla extract
1 vanilla bean, halved lengthwise, seeds scraped and reserved
1/2 cup all-purpose flour
Pinch of salt
1/2 cup hazelnuts, toasted, skins rubbed off with a kitchen towel while still warm
10 tablespoons (1 1/4 sticks) unsalted butter, softened
1 cup confectioners' sugar
2 tablespoons heavy cream
Pinch of salt

Steps:

Make the tuiles: Preheat oven to 350 degrees. Put butter and sugar in the bowl of an electric mixer fitted with the paddle attachment. Mix on medium-high speed until pale and fluffy, about 2 minutes. Mix in egg whites, extract, and vanilla seeds; reserve vanilla bean for another use. Reduce speed to low. Add flour and salt; mix until just combined.
Spoon 1 1/2 teaspoons batter onto a baking sheet lined with parchment paper; using an offset spatula, spread into a 4-inch round. Repeat, forming 3 more rounds and spacing 2 inches apart.
Bake until golden, about 10 minutes. Transfer sheet to a wire rack. Working quickly, remove 1 cookie with an offset spatula, and roll around the handle of a wooden spoon to form a 1/4-inch tube. Hold until tuile begins to harden, about 10 seconds; transfer tuile to a wire rack to cool completely. Repeat with remaining cookies. If cookies become too cool to shape, return to oven for 30 seconds. Repeat with remaining batter.
Make the cream: Process nuts in a food processor until they resemble coarse meal. Reserve 3 tablespoons; transfer remainder to a medium bowl. Add butter, sugar, cream, and salt; stir until smooth. Transfer to a pastry bag fitted with a 1/4-inch plain round tip (such as Ateco #10). Gently pipe filling into 1 end of a tuile, forcing it halfway in with a skewer; pipe into opposite end until filled. Dip each end in reserved nuts. Repeat with remaining tuiles. Serve immediately.
