Ingredients
- 1 cup (226 g) melted unsalted butter
- 1 1/4 cups granulated sugar
- 1/2 cup packed brown sugar
- 3 large eggs
- 2 tsp vanilla extract
- 1 cup all-purpose flour
- 3/4 cup unsweetened cocoa powder
- 1 tbsp instant espresso powder
- 1/2 tsp salt
- 1 tsp for topping flaky sea salt
Instructions
- Step 1: Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
- Step 2: In a large mixing bowl, whisk together 1 cup melted unsalted butter, 1 1/4 cups granulated sugar, and 1/2 cup packed brown sugar until combined and glossy.
- Step 3: Beat in 3 large eggs one at a time, followed by 2 tsp vanilla extract, mixing well after each addition.
- Step 4: Sift together 1 cup all-purpose flour, 3/4 cup unsweetened cocoa powder, 1 tbsp instant espresso powder, and 1/2 tsp salt.
- Step 5: Gradually fold the dry ingredients into the wet ingredients using a spatula until just combined, being careful not to overmix.
- Step 6: Spread the batter evenly into the prepared pan, smoothing the top with an offset spatula.
- Step 7: Sprinkle 1 tsp flaky sea salt evenly over the batter.
- Step 8: Bake for 25-28 minutes until the edges are set but the center still looks slightly soft — a toothpick inserted will come out with moist crumbs.
- Step 9: Cool completely in the pan on a wire rack before lifting out using the parchment overhang and cutting into 16 bars.
