1-First Steps: Preheat your oven to 350°F and position the rack in the lower third for even baking. Line an 8-inch square pan with parchment paper or foil, leaving an overhang for easy removal, and lightly spray it with nonstick spray. This preparation helps prevent sticking and ensures your brownies come out cleanly.

2-First Steps: Melt the 1/2 cup unsalted butter and 5 ounces semisweet chocolate in a heatproof bowl over simmering water or in the microwave in 30-second intervals until smooth. Once melted, whisk in the 1/4 cup unsweetened cocoa powder and let it cool slightly to avoid scrambling the eggs later.

3-Mixing and Baking the Batter: In a separate bowl, whisk the 3 large eggs, 1 cup granulated sugar, 1 teaspoon vanilla extract, and 1/2 teaspoon salt until frothy this step adds air for a lighter texture. Add the warm chocolate mixture and mix well, then fold in the 1 cup all-purpose flour until no streaks remain for a uniform batter.

4-Mixing and Baking the Batter: Spread the batter into the prepared pan and bake for 20-25 minutes, or until the top looks dry and the edges pull away from the pan. For the topping, whisk together the 1 cup light brown sugar, 1/4 cup melted unsalted butter, 2 tablespoons milk, and 1/2 teaspoon vanilla extract, then stir in the 1 cup chopped pecans.

5-Finishing Touches: Spread the topping evenly over the baked brownies and return to the oven for another 15 minutes to create that gooey layer. Cool completely in the pan on a wire rack for about 2 hours before cutting into squares, and refrigerate for 45-60 minutes for cleaner slices using a sharp knife. With a prep time of 15 minutes, cook time of 35 minutes, and total time of 50 minutes, it’s a quick recipe to master.
