Ingredients
Brownies
- Cooking spray, for greasing
- 1 cup butter, melted
- 1/2 cup cocoa powder
- 1/4 teaspoon kosher salt
- 2 cups sugar
- 2 cups flour
- 4 large eggs, beaten
- 1 tablespoon vanilla extract
Frosting
- 1/4 cup butter, softened
- 1/4 cup cocoa powder
- 2 teaspoons vanilla extract
- 3 tablespoons milk
- 2 1/2 cups powdered sugar
Instructions
- Prepare baking pan: Preheat the oven to 350°F (175°C). Line a 9 x 13-inch rimmed baking sheet with parchment paper and lightly grease it with cooking spray to prevent sticking.
- Make brownie batter: In a large bowl, stir together the melted butter and cocoa powder until fully combined. Add sugar and kosher salt, mixing well to incorporate. Then stir in the flour evenly. Finally, mix in the beaten eggs and vanilla extract until the batter is smooth and fully blended.
- Bake the brownies: Pour the brownie mixture into the prepared baking pan, spreading it evenly. Bake in the preheated oven for 18 to 21 minutes until just done but still fudgy. Remove from oven.
- Prepare frosting: While the brownies bake, whisk together softened butter, cocoa powder, vanilla extract, and milk in a bowl until smooth. Gradually add powdered sugar, whisking continuously until the frosting is thick, creamy, and free of lumps.
- Apply frosting: Let the brownies cool for 10 minutes so they are slightly warm but not hot. Spread the prepared frosting evenly over the top of the warm brownies for smooth application.
- Cool and serve: Allow the brownies to cool completely at room temperature for about 20 minutes so the frosting sets properly. Once cool, cut into 16 squares and serve.
Notes
- For best fudgy texture, avoid overbaking the brownies. Check at 18 minutes and remove when a toothpick shows moist crumbs.
- Using parchment paper helps lift brownies easily from the pan and makes clean-up simple.
- You can substitute salted butter if kosher salt is unavailable, but reduce extra salt added accordingly.
- Store leftover brownies in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
- To make frosting vegan, substitute butter with plant-based margarine and milk with almond or oat milk.
