Ingredients
1/2 cup whole hazelnuts, toasted1 tablespoon confectioners’ sugar1 tablespoon plus 1/2 cup butter, divided2 tablespoons plus 1 cup all-purpose flour, divided2 large eggs, separated, room temperature2/3 cup sugar1/4 teaspoon vanilla extract1 teaspoon baking powder1/8 teaspoon saltAdditional confectioners’ sugar, optional
Preparation
In a food processor, combine the hazelnuts and confectioners’ sugar; cover and process until nuts are finely chopped. Set aside. Melt 1 tablespoon butter; brush two 12-shell madeleine pans with butter. Dust with 2 tablespoons flour; tap pans to remove excess flour and set aside. Place remaining 1/2 cup butter in a saucepan; melt over low heat until it turns a light amber color, 4-5 minutes. Set aside to cool.
In a large bowl, beat egg yolks and sugar until thick and a pale lemon color. Stir in melted butter and vanilla. Combine the baking powder, salt and remaining flour; stir into butter mixture just until combined. In a small bowl, beat egg whites on high speed until stiff peaks form; fold into batter. Gently fold in reserved nut mixture.
With a tablespoon, fill prepared pans two-thirds full. Bake at 325° until golden brown, 18-20 minutes. Cool for 2 minutes before inverting pans onto wire racks to remove cookies. Cool completely. Lightly dust with additional confectioners’ sugar if desired.
