Ingredients
Scale
Cake
- 2 cups all-purpose flour
- 2 cups sugar
- 1 teaspoon baking soda
- ½ teaspoon salt
- ½ cup buttermilk
- 2 large eggs
- 1 teaspoon vanilla
- 2 sticks unsalted butter
- 4 tablespoons cocoa powder
- 1 cup water
Frosting
- ½ cup (1 stick) butter
- 6 tablespoons buttermilk
- 1 pound confectioners sugar
- 4 tablespoons cocoa powder
- 1 teaspoon vanilla
Instructions
- Preheat and prepare pan: Preheat your oven to 350°F. Spray a jelly roll pan lightly with non-stick cooking spray to prevent sticking.
- Mix dry ingredients: In a large mixing bowl, whisk together the all-purpose flour, sugar, baking soda, and salt until well combined. Set aside.
- Mix wet ingredients: In a separate small bowl, combine the buttermilk, eggs, and vanilla extract. Whisk gently and set aside.
- Make chocolate butter mixture: In a medium saucepan over medium heat, melt the butter, cocoa powder, and water together. Stir frequently and bring the mixture to a boil.
- Combine mixtures: Pour the hot chocolate butter mixture into the bowl of dry ingredients. Stir quickly to combine, then immediately add the wet buttermilk-egg mixture and mix until smooth and fully incorporated.
- Bake the cake: Pour the batter evenly into the prepared jelly roll pan. Bake in the preheated oven for 20 minutes or until a toothpick inserted into the center comes out clean.
- Cool the cake: Remove the cake from the oven and transfer to a wire rack to cool slightly while you prepare the frosting.
- Prepare frosting: In a saucepan over medium heat, melt the butter, cocoa powder, and buttermilk together, stirring constantly. Bring the mixture to a gentle boil.
- Add sugar and vanilla: Remove the saucepan from heat and whisk in the confectioners sugar and vanilla extract until smooth and glossy.
- Frost cake: Pour the warm frosting evenly over the slightly warm cake, spreading if needed so it covers the surface completely.
- Set and serve: Let the frosting cool and set before cutting the cake into squares and serving.
Notes
- Use room temperature eggs for best mixing results.
- To make the cake nut-free, omit any optional nuts or toppings sometimes added in variations.
- Make sure not to overbake to keep the cake moist and tender.
- The frosting is best poured over warm cake so it soaks in perfectly.
- Substitute regular milk for buttermilk by adding 1 tablespoon vinegar or lemon juice per ½ cup milk and letting it sit for 5 minutes.
- Store leftovers in an airtight container at room temperature for up to 3 days.
- The cake can also be baked in a 9×13 inch pan but adjust baking time up to 25-30 minutes.
