Flourless Deep Dark Chocolate Cookies - cooking recipe

Ingredients

nonstick vegetable cooking spray
1 1/2 cups bittersweet chocolate chips, divided (about 9 ounces)
3 large egg whites, room temperature
2 cups powdered sugar, divided (can also use granulated sugar)
1/2 cup unsweetened cocoa powder
1 tablespoon cornstarch
1/4 teaspoon salt

Preparation

Preheat oven to 400\u00b0F Spray 2 large baking sheets with nonstick spray. Melt 1 cup chocolate chips in glass bowl in microwave, stirring twice, about 2 minutes. Cool slightly.
Using electric mixer, beat whites in large bowl to soft peaks. Gradually beat in 1 cup sugar. Continue beating until mixture resembles soft marshmallow creme.
Whisk 1 cup sugar, cocoa, cornstarch, and salt in medium bowl to blend. On low speed, beat dry ingredients into meringue. Stir in lukewarm chocolate and 1/2 cup chocolate chips (dough will become very stiff).
Roll 1 rounded tablespoon dough into ball (can coat in additional sugar if you want).
Place on prepared sheet. Repeat with remaining dough, spacing 2 inches apart. Bake until puffed and tops crack, about 8-10 minutes (don't overbake!). Cool on sheets on rack 10 minutes. Transfer to rack; cool.
