Chocolate Sheet Cake Recipe
Yields: 12 servings
Time: 45 minutes, plus cooling time
Ingredients:
Chocolate Cake
- 2 cups all-purpose flour
- ¾ cup cocoa powder (baking cocoa)
- 1 ½ teaspoon baking soda
- 1 teaspoon baking powder
- ½ teaspoon kosher salt
- 1 ½ cups granulated sugar
- ½ cup unsalted butter, melted (or vegetable oil)
- 1 cup milk
- 2 large eggs, lightly beaten
- 1 cup Mountain Valley Sparkling Water
Chocolate Buttercream Frosting
- 1 cup unsalted butter, room temperature
- 2 cups powdered sugar, sifted
- ½ cup cocoa powder, sifted
- ½ teaspoon kosher salt
- 1 ½ teaspoons vanilla extract
- 1-2 tablespoons milk
- Chocolate sprinkles, for garnish
Directions:
- Preheat the oven to 350 degrees. Line a 9x13 baking pan with parchment paper and set aside.
- In a large bowl, whisk together flour, cocoa, baking soda, baking powder, salt and sugar.
- Add the melted butter, milk, eggs and sparkling water. Mix until the wet ingredients are fully incorporated into the dry ingredients.
- Transfer the batter to the pan and spread evenly. Bake for 28 to 32 minutes, until a toothpick inserted in the center comes out with little to no crumbs. Cool completely on a wire rack before frosting.
- In the bowl of a stand mixer, beat the butter on medium speed until pale and fluffy, about 3 minutes. Add powdered sugar, cocoa and salt and mix on medium-low speed until well combined. Add vanilla and milk, mixing just until combined, scraping down the bowl as necessary.
- Transfer the frosting to the cooled cake and spread in an even layer over the top. Garnish with chocolate sprinkles and serve.
