Ingredients

  • For the Brownies:

  • 1/2 cup unsalted butter, melted

  • 1 cup granulated sugar

  • 2 large eggs, room temperature

  • 1 teaspoon vanilla extract

  • 1/3 cup unsweetened cocoa powder

  • 1/2 cup all-purpose flour

  • 1/4 teaspoon salt

  • 1/4 teaspoon baking powder

  • For the Chocolate Frosting:

  • 3 tablespoons unsalted butter, softened

  • 1 1/2 cups powdered sugar

  • 2 tablespoons unsweetened cocoa powder

  • 2 tablespoons milk

  • 1/2 teaspoon vanilla extract

Directions

  • Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper, leaving overhang on two sides for easy removal.
  • Mix melted butter and granulated sugar in a large bowl until well combined. Add eggs and vanilla, whisking vigorously for about 1 minute until mixture is smooth and glossy.
  • Sift cocoa powder, flour, salt, and baking powder directly into the wet ingredients. Fold gently with a spatula just until no dry streaks remain—don’t overmix or brownies will be cakey instead of fudgy.
    💡 Tip: Stop mixing as soon as the flour disappears for the fudgiest texture.
  • Pour batter into prepared pan and spread evenly to all corners. Bake for 23-25 minutes until a toothpick inserted in the center comes out with just a few moist crumbs.
  • Let brownies cool completely in the pan on a wire rack before frosting, about 45 minutes. This prevents the frosting from melting.
  • Beat softened butter in a medium bowl until creamy. Add powdered sugar and cocoa powder, mixing on low speed to prevent a sugar cloud.
  • Pour in milk and vanilla, then beat on medium-high speed for 2-3 minutes until frosting is light and fluffy. Add an extra tablespoon of milk if too thick, or more powdered sugar if too thin.
  • Spread frosting evenly over cooled brownies using an offset spatula or butter knife. Cut into 16 squares and serve.
    💡 Tip: Wipe your knife clean between cuts for the neatest edges.

🎯 Pro Tips & Substitutions

Yes! Bake the brownies up to 2 days ahead and store unfrosted in an airtight container at room temperature. Add the frosting a few hours before serving for best texture. You can also freeze unfrosted brownies for up to 3 months—just thaw completely before frosting.

Use Dutch-process cocoa for deeper chocolate flavor, or natural unsweetened cocoa for brighter notes. Hershey’s and Ghirardelli both work beautifully. Avoid hot cocoa mix as it contains sugar and milk powder. For ultra-rich brownies, try dark cocoa powder like Hershey’s Special Dark.

Overmixing the batter after adding flour develops gluten, creating a cake-like texture. Mix just until the dry ingredients disappear. Also check your oven temperature—baking above 350°F or overbaking will dry them out. Pull brownies when a toothpick has moist crumbs, not when it’s completely clean.

A 9×9-inch pan works but reduces bake time to 20-22 minutes since brownies will be thinner. For a 9×13-inch pan, double the entire recipe. Metal pans conduct heat better than glass, so reduce oven temperature by 25°F if using glass and add 5 minutes to bake time.

Store frosted brownies in an airtight container at room temperature for up to 4 days. Layer parchment paper between stacked brownies to prevent sticking. Refrigerate if your kitchen is warm, but bring to room temperature before serving for best fudgy texture. Frozen frosted brownies keep for 2 months.

❓ Frequently Asked Questions

Yes! Substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. Bob’s Red Mill and King Arthur both work well. The texture will be slightly more delicate, so handle gently when cutting. Let them cool completely before removing from the pan.

A hand mixer makes the fluffiest frosting, but you can whisk by hand for about 5 minutes. The key is beating enough air into the butter and sugar mixture. If whisking manually, make sure your butter is very soft (almost room temperature) for easier mixing.

Absolutely! Fold in 1/2 cup chocolate chips, chopped nuts, or peanut butter chips after mixing the batter. For swirled brownies, dollop 1/4 cup peanut butter or cream cheese on top and swirl with a knife before baking. Add-ins won’t affect baking time.
