Ingredients
- 6 tbsp unsalted butter
- 4 oz bittersweet chocolate, chopped
- 3/4 cup granulated sugar
- 2 large eggs
- 1 tsp vanilla extract
- 1/2 cup all-purpose flour
- 2 tbsp unsweetened cocoa powder
- 1/4 tsp salt
- 1/3 cup chopped walnuts
Instructions
- Step 1: Preheat the oven to 325°F. In a heatproof bowl over simmering water, melt 6 tbsp unsalted butter with 4 oz chopped bittersweet chocolate, stirring until smooth and glossy. Remove from heat.
- Step 2: Whisk in 3/4 cup granulated sugar until combined, then beat in 2 large eggs and 1 tsp vanilla extract until smooth.
- Step 3: Sift together 1/2 cup all-purpose flour, 2 tbsp unsweetened cocoa powder, and 1/4 tsp salt. Fold the dry ingredients gently into the chocolate mixture until just combined.
- Step 4: Stir in 1/3 cup chopped walnuts. Pour batter into a greased 8-inch square baking pan and smooth the top.
- Step 5: Bake for 20 minutes, then check by inserting a toothpick; it should come out with moist crumbs but not wet batter, ensuring a half-baked gooey center. Remove and cool completely before cutting into squares.
