Nutty Brownie Thins Recipes

Steps:

• Position a rack in center of oven; preheat to 325°F. Very generously butter an 18x13" rimmed baking sheet (do not line with parchment).
• Melt remaining 1/2 cup butter in a small heatproof bowl in the microwave or set over a pot of barely simmering water. Mix sugar, cocoa powder, vanilla, and salt in a medium bowl. Pour butter over and stir until smooth. Add eggs one at a time, stirring vigorously with a wooden spoon or rubber spatula after each addition, until batter is thick, shiny, and smooth. Stir in flour until well incorporated, then beat vigorously for 30-40 strokes. Stir in nuts or chocolate chips.
• Using a spatula, spread batter into a thin, even layer to edges and into corners of prepared sheet (batter will seem scant but brownies will rise to about 1/4" thick).
• Bake brownies until firm to the touch and a tester inserted into the center comes out with moist crumbs (not runny batter) attached, 15-18 minutes.
• Transfer to a wire rack and let cool completely. Cut into 36 pieces and serve.
• Do Ahead
• Brownies can be made 5 days ahead. Store in an airtight container at room temperature, or freeze up to 6 months.

Steps:

• Position rack in lowest third of oven; preheat to 350°F. Butter 2 baking sheets. Place butter and chocolate in medium microwave-safe bowl. Microwave on medium-high power until almost completely melted, about 1 minute. Whisk until smooth. Add sugar and egg; whisk until smooth, about 1 minute. Add flour, both extracts, and salt; stir just to blend. Let batter stand 10 minutes.
• Scoop rounded teaspoonfuls batter onto prepared baking sheets, spacing apart (12 per sheet). Spray sheet of plastic wrap lightly with nonstick spray. Place, sprayed side down, over cookies. Using fingers, press each mound into 21/2- to 2 3/4-inch round. Remove plastic wrap. Sprinkle pistachios over rounds. Bake cookies, 1 sheet at a time, until slightly darker at edges and firm in center, about 7 minutes. Cool on sheet 2 minutes. Transfer cookies to rack; cool completely. DO AHEAD: Can be made 5 days ahead. Store airtight at room temperature.
