Frosting
- In a large saucepan over medium heat, ADD butter, buttermilk, and peanut butter. STIR constantly until the mixture begins to boil.
- LOWER heat and gradually ADD powdered sugar. This mixture will be lumpy. Continue STIRRING over medium-low heat until smooth. REMOVE from heat and ADD vanilla extract.
- Keep the frosting warm (stirring as necessary) until the cake is finished cooking. POUR frosting over the warm cake. Use an offset spatula to SPREAD the frosting until smooth and evenly distributed.
- DRIZZLE with chocolate sauce. Set aside at least 20 minutes until cool enough to slice and serve.
Notes
This recipe uses unsalted butter. If you only have salted butter, you can omit the salt from the recipe.
You can make your own buttermilk using whole milk and lemon juice or distilled vinegar. For every 1 cup of milk, stir in 1 tablespoon of lemon juice or vinegar.
Using a different-sized sheet pan will require the cooking time to be adjusted.
Store the sheet cake covered at room temperature for up to 5 days.
