Ingredients
- Bars:
- 1/2 cup unsalted butter
- 1/4 cup unsweetened baking cocoa powder
- 1/2 cup vegetable oil
- 1 cup water
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 1/2 teaspoon salt
- 1/2 cup buttermilk
- 2 eggs, beaten
- 1 teaspoon baking soda
- 1 teaspoon vanilla extract
- Frosting:
- 1/3 cup buttermilk
- 1/4 cup unsweetened cocoa powder
- 1/2 cup unsalted butter
- 4 cups powdered sugar
Instructions
- Preheat oven to 350°F (175°C). Grease or spray an 11×15-inch baking pan with nonstick spray and set aside.
- In a large mixing bowl, combine flour, granulated sugar, and salt. Mix and set aside.
- In a medium saucepan over medium-high heat, combine butter, cocoa powder, vegetable oil, and water. Stir constantly until it comes to a boil, then remove from heat.
- Pour the hot mixture over the dry ingredients and stir until combined.
- Add buttermilk, beaten eggs, baking soda, and vanilla extract. Stir until fully incorporated.
- Pour the brownie batter into the prepared pan and spread evenly.
- Bake for 22–27 minutes or until a toothpick inserted in the center comes out clean.
- While the brownies are baking, make the frosting. In a medium saucepan, combine buttermilk, cocoa, and butter. Bring to a boil over medium-high heat while stirring constantly.
- Remove from heat and gradually add powdered sugar, 2 cups at a time, stirring between additions until smooth.
- Pour the warm frosting over the brownies as soon as they come out of the oven. Let cool completely to set the frosting.
Notes
- Frost the brownies while both the bars and frosting are hot for a smooth, glossy finish.
- Store leftovers in an airtight container at room temperature for up to 3 days, or refrigerate for longer freshness.
- Let brownies cool fully before slicing for cleaner cuts.
- Add chopped nuts or chocolate chips to the batter for extra texture.
