Chocolate sheet cake with peanut butter frosting:
Ingredients:
For the cake:
- 1 cup butter
- 2 cups sugar
- 2 eggs
- 1 teaspoon vanilla
- 1/4 cup hot water
- 1 Tablespoon instant espresso or coffee
- 3 cups cake flour
- 1/4 cup cocoa powder
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1 ½ cup buttermilk
For the frosting:
- 3 cups icing sugar
- 1/2 cup peanut butter
- 1/2 cup butter (softened)
- 1/2 teaspoon vanilla
- 1/2 teaspoon salt
- 1/3 cup heavy cream
- Chopped peanuts and chocolate shavings for garnish (if desired)
Instructions:
For the cake:
- Preheat oven to 350 degrees F. and butter and flour a 9 x 13 baking pan. I lined the bottom of it with parchment paper, but you don't need to if you are just going to serve it in the pan.
- Cream together the butter and sugar until very smooth, about 3-5 minutes.
- Add eggs, one at a time, mixing until combined after each.
- Dissolve the instant espresso or coffee in the hot water. Add to the butter mixture along with the vanilla, mixing until combined.
- Combine the dry ingredients in a separate bowl, making sure to sift them to remove any lumps.
- Add the dry ingredients and the buttermilk to the cake batter in 3 alternate additions, stirring just until combined after each.
- Pour batter into your prepared cake pan and give it a couple of taps to even it out.
- Bake at 350 degrees F. for 30-40 minutes. Mine was done at about 32 minutes, but some oven I have used take up to 45 minutes to bake cakes so just start checking at 30. When a toothpick comes out clean, it's done.
For the frosting:
- Beat together all ingredients except for the heavy cream until smooth.
- Add in the heavy cream and beat on high until light and creamy, about 3 minutes.
- Spread over the sheet cake, sprinkle with chopped peanuts and chocolate shavings and enjoy!
