Cocoa powder is a vital ingredient in many brownie recipes, providing the rich chocolate flavor we all crave. There are two main types of cocoa powder: natural (unsweetened) and Dutch-processed.

Natural Cocoa Powder: This type has a lighter flavor and a slightly drier texture, making it ideal for achieving a chewy consistency.
Dutch-Processed Cocoa Powder: This variety offers a deeper flavor and darker color, resulting in a richer brownie. Many bakers prefer Dutch cocoa for its intense chocolate taste.

For this recipe, you can choose either type, but Dutch-processed cocoa will give you a more decadent result.

Here’s what you’ll need to make these delicious chewy brownies:

1 cup (120g) all-purpose flour
1/2 cup (43g) unsweetened cocoa powder (Dutch-processed recommended)
1/2 teaspoon baking powder
1/2 teaspoon salt
3/4 cup (170g) unsalted butter
1 and 1/3 cups (265g) granulated sugar
2 large eggs
1 large egg yolk
2 teaspoons vanilla extract (optional)
3/4 cup (128g) chocolate chips (optional)

Preheat your oven to 350°F (175°C). Line a 9x9-inch baking pan with parchment paper or grease it lightly to prevent sticking.

In a medium saucepan, melt the butter over medium-low heat. Once melted, remove it from the heat and stir in the sugar, cocoa powder, and salt until well combined.

Allow the mixture to cool slightly before adding the eggs and egg yolk. Whisk vigorously until the batter is thick and smooth.

In a separate bowl, sift together the flour and baking powder. Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix, as this can lead to cakey brownies.

If desired, fold in the chocolate chips for an extra chocolatey flavor.

Spread the brownie batter evenly in the prepared pan. Bake for 28-30 minutes, or until the edges are set and the center is slightly underbaked. A toothpick inserted into the center should come out with a few moist crumbs.

Let the brownies cool in the pan for at least 2 hours before slicing. This cooling period helps them set and makes cutting easier.

Avoid Overmixing: Mix only until the ingredients are combined to prevent air from getting trapped in the batter, which can lead to cakey brownies.
Don’t Overbake: Remove the brownies from the oven while they still have a slight jiggle in the center. They will continue to firm up as they cool.
Use Quality Cocoa Powder: The flavor of your brownies can vary significantly based on the quality of cocoa powder used. Brands like Guittard and Penzey’s are excellent choices.
