Preparation

1. Line two sheet pans with parchment paper. Position racks in the upper and lower thirds of the oven. Preheat oven to 400 F.
2. Melt 1 cup of the chocolate chips in the microwave in a glass pitcher at 1 - 2 minutes increments until just melted, stirring. Set aside.
3. Place egg whites into the bowl of an electric mixer and beat to soft peak stage. Slowly add 1 cup of the confectioner's sugar and continue beating until mixture resembles marshmallow creme. In a separate bowl combine 1 cup of the confectioner's sugar, cocoa powder, cornstarch, and salt. Whisk to blend.
4. Switch to using the paddle in the electric mixer. With the mixer on low speed gradually spoon in the combined dry ingredients. Mixture will become very stiff. Add melted chocolate, remaining 1/4 cup of chocolate chips and the walnuts.
5. Place the remaining 1/2 cup of confectioner's sugar into a medium bowl. Drop 4 scant tablespoons of the dough into the confectioner's sugar. Pick up each tablespoon of dough individually and roll it into a ball, coaxing the sugar to adhere to it. Place sugar-covered balls onto prepared sheet pan. Repeat with the remaining dough.
6. Bake until puffed and the tops crack slightly, about 10-12 minutes. Slide parchment paper onto cake racks to cool. Store in an airtight container.
