Instructions
- Step 1: Preheat oven to 350°F. Line an 8-inch square baking pan with parchment paper, leaving an overhang for easy removal.
- Step 2: In a microwave-safe bowl, combine 1/2 cup unsalted butter and 6 oz chopped bittersweet dark chocolate. Microwave in 30-second increments, stirring in between, until melted and smooth.
- Step 3: Whisk in 1 cup granulated sugar until combined. Add 2 large eggs one at a time, whisking well after each addition, then stir in 1 tsp vanilla extract.
- Step 4: In a separate bowl, sift together 3/4 cup all-purpose flour, 1/4 cup unsweetened cocoa powder, 1 tsp unsweetened chili powder, 1/4 tsp salt, and 1/8 tsp ground cayenne pepper if using.
- Step 5: Gradually fold the dry ingredients into the wet mixture with a spatula, mixing just until combined.
- Step 6: Pour the batter into the prepared pan and smooth the top. Bake for 25-28 minutes until a toothpick inserted near the center comes out with moist crumbs.
- Step 7: Cool completely in the pan before lifting out and cutting into 16 squares.
