- 2 cups all purpose flour
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1 cup (2 sticks) plus 2 tablespoons unsalted butter, room temperature
- 1 1/4 cups (firmly packed) dark brown sugar
- 2 tablespoons instant espresso powder
- 1/2 teaspoon almond extract
- 1 cup semisweet chocolate chips
- 1/2 cup sliced almonds
- Preheat oven to 325°F. Whisk first 3 ingredients in medium bowl to blend.
- Using electric mixer, beat butter and sugar in another medium bowl until blended, about 2 minutes. Add espresso powder and almond extract; beat 1 minute. Stir in flour mixture in 3 additions, mixing until just absorbed after each addition. Stir in chocolate chips and almonds (dough will be thick).
- Turn dough out onto ungreased rimmed baking sheet. Using hands, press dough into 12-inch square. Pierce all over with fork at 1-inch intervals.
- Bake until edges are lightly browned and beginning to crisp, 45 to 50 minutes. Cool on sheet 1 minute. Cut into 48 bars. Immediately transfer to rack; cool (bars will crisp as they cool). DO AHEAD: Can be made 5 days ahead. Store in airtight container at room temperature.
