- 1/2 pound (2 sticks) plus 1 1/2 tablespoons butter
- 3/4 cup plus 2 tablespoons powdered sugar
- Pinch salt
- Dash vanilla
- 1 extra-large egg white
- 2 cups cake flour, sifted
- 1/4 cup cocoa powder
- 2 tablespoons plus 1 teaspoon cornstarch

Divide the mixture in half. Add the cocoa powder to one half and the cornstarch to the other half. Place each batter a separate pastry bag, then place both bags inside a larger pastry bag fitted with a 3/4-inch star tip.
Pipe rosettes or drops onto a parchment paper lined baking sheet. Bake for 12 to 15 minutes.
