Ingredients
For the Cake
- 2 cups all-purpose flour
- 2 cups sugar
- 1 cup unsalted butter
- 1 cup water
- 1/2 cup creamy peanut butter
- 1/2 cup buttermilk
- 4 large eggs
- 2 teaspoons baking soda
- 1 teaspoon vanilla extract
- 1/2 teaspoon salt
For the Frosting
- 1/2 cup unsalted butter
- 1/2 cup creamy peanut butter
- 1/4 cup milk
- 4 cups powdered sugar
- 1 teaspoon vanilla extract
Instructions
- Preheat your oven to 350°F (175°C). Grease a large sheet pan (a half-sheet pan works perfectly) with cooking spray or butter.
- In a large bowl, whisk together the flour, sugar, baking soda, and salt until well combined.
- In a saucepan, combine the butter and water. Bring to a boil, stirring occasionally. Once boiling, pour this mixture into the dry ingredients and mix well.
- Stir in the creamy peanut butter until well blended.
- In another bowl, beat the eggs, buttermilk, and vanilla together. Add this mixture to your cake batter and mix until just combined.
- Pour the batter into your greased sheet pan and spread it evenly. Bake for 20-25 minutes, or until a toothpick comes out clean from the center.
- While the cake is baking, make the frosting by melting the butter in a saucepan over medium heat. Add in the peanut butter and milk, stirring until well combined. Gradually add in the powdered sugar and vanilla, mixing until smooth.
- When the cake is done and cooled slightly, pour the frosting over the warm cake for a luscious finish.
- Let the cake cool completely before cutting it into generous squares.
