Ingredients
For the cake:
- 1 cup water
- 1 cup butter 2 sticks
- ½ cup peanut butter
- 2 cups sugar
- 1 teaspoon vanilla extract
- 2 large eggs
- 1 teaspoon baking soda
- ¼ teaspoon salt
- 2 cups all-purpose flour
- ½ cup buttermilk
For the icing:
- ½ cup butter 1 stick
- ¼ cup creamy peanut butter
- ½ cup dark brown sugar
- 4-6 tablespoon buttermilk (or half and half or milk)
- 1 teaspoon vanilla extract
- 3½-4 cups powdered sugar
Instructions
For the cake:
- Preheat the oven to 350˚F. Generously spray a 12x18-inch sheet pan with baking spray OR rub with shortening then add a tablespoon of flour and tilt the pan in all directions to coat the shortening with flour.
- Combine water, butter and peanut butter in a medium-large, microwave-safe bowl. Cook on high power for 2-2½ minutes or until the butter is melted. Add the sugar and vanilla, then whisk until well combined. Set aside for 5 minutes to cool.
- Add the eggs and whisk until smooth then add the baking soda and salt. Whisk until well combined.
- Add the flour, whisking vigorously until lump-free then add the buttermilk and stir until well combined.
- Pour the batter into the prepared pan and smooth to an even layer. Bake for 20-25 minutes, until a toothpick inserted in the center, comes out clean and the top feels firm and springs back lightly when touched.
- Cool for 20 minutes then top with the icing. Spread the icing with a knife to cover the surface. If desired, swirl the icing with the back of a small spoon for a pretty presentation. Serve warm or at room temperature.
For the icing:
- Combine the butter, dark brown sugar and peanut butter in a medium-large microwave-safe bowl. Cook on high power for 1 minute. Whisk well then return to the microwave for another minute.
- Add 4 tablespoons of the buttermilk (or half and half or milk) and vanilla. Whisk well to combine. Add 3½ cups of powdered sugar and whisk until smooth. You’re looking for a fairly thick but still pourable icing. If too thick, add a bit more buttermilk. If too thin, add a little more powdered sugar and stir again until nice and smooth.
