Mocha Meringue Sandwich Cookies Recipes

Steps:

• Preheat oven to 300 degrees, with racks in upper and lower thirds. Line two large baking sheets with parchment paper; set aside. In a small bowl, whisk together sugar and cornstarch; set aside.
• In a large bowl, using an electric mixer, beat egg whites and salt on medium speed until frothy. Beating constantly, add sugar mixture 1 tablespoon at a time; beat until stiff, glossy peaks form, 6 to 8 minutes total (scrape down the bowl halfway through). Add espresso powder and cocoa; beat until well blended. With a rubber spatula, fold in chocolate chips.
• Drop batter by level tablespoons onto prepared baking sheets, about 1 inch apart. Bake until crisp, about 40 minutes, rotating sheets halfway through. Cool completely on sheets, about 20 minutes.

Steps:

• Sift together flour, cocoa, salt, espresso powder, and cinnamon into a large bowl; set aside. Put butter and sugar into the bowl of an electric mixer fitted with the paddle; mix on medium until pale and fluffy. Mix in egg and vanilla. Reduce speed to low. Add flour mixture; mix until just combined. Stir in cocoa nibs.
• Turn out dough onto a lightly floured surface; roll into a 2-inch-diameter log. Wrap in parchment; transfer to a paper towel tube to hold shape. Refrigerate until firm, at least 1 hour or up to overnight.
• Preheat oven to 350 degrees. Unwrap log, and let soften slightly at room temperature, about 5 minutes. Brush with water, then roll in sanding sugar. Cut log into 1/4-inch thick rounds. Space 1 inch apart on baking sheets lined with parchment paper.
• Bake until centers are set, about 10 minutes. Transfer to wire racks; cool completely.
