Classic Fudgy Brownie

step 1.

Preheat the oven to 350°F (175°C). Line an 8-inch square baking pan with parchment paper, leaving an overhang on two sides for easy removal.

step 2.

In a medium microwave-safe bowl, melt the butter. Add the sugar and whisk until well combined.

step 3.

Add the eggs one at a time, whisking well after each addition. Stir in the vanilla extract.

step 4.

Sift in the cocoa powder, flour, salt, and baking powder. Using a rubber spatula, gently fold the dry ingredients into the wet ingredients just until combined. Do not overmix.

step 5.

If using, fold in the chocolate chips.

step 6.

Pour the batter into the prepared pan and spread it evenly. Bake for 25 to 30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.

step 7.

Remove from the oven and let cool completely in the pan on a wire rack. Once cooled, lift the brownies out using the parchment paper and cut into 16 squares.

step 8.

Store the brownies in an airtight container at room temperature for up to 1 week, or in the refrigerator for up to 2 weeks. Brownies can also be frozen, tightly wrapped, for up to 3 months. Thaw at room temperature before serving.
