In a large mixing bowl, beat together eggs, sugar, and almond extract with a mixer at high speed until pale and fluffy, approximately 5 minutes.
In a small bowl, whisk together flour, cocoa powder, baking powder, and salt. Add half of flour mixture to egg mixture, beating at medium speed until incorporated. Add remaining flour mixture, beating until incorporated. Gradually add butter, beating until well blended. Let batter stand for 5 minutes.
Spoon 1 tablespoon batter into each prepared well of madeleine pans. Using an of set spatula, smooth tops of batter.
Bake until madeleines are firm to the touch, 5 to 7 minutes. Remove madeleines from molds. Let cool completely on wire racks.
Garnish with a dusting of confectioners’ sugar, if desired.
