Peanut Butter Cake makes a perfect cake for the peanut butter lover. This makes a great sheet cake topped with chocolate frosting or peanut butter icing.
Remember that peanut butter icing recipe I shared the other day? While it is fabulous on brownies or a chocolate cake, if you love peanut butter as much as I do, then you will adore it on that icing on this peanut butter cake.
It took years of trial and error for me to get the recipe close enough to the one served in my school cafeteria growing up. The final peanut butter cake recipe is rich, decadent, and one that you’ll definitely want a large glass of ice cold milk or a cup of coffee to go along with while you eat.
Made of simple ingredients that you most likely have on hand, this is one of those cakes that you can quickly mix together and have baked for a special treat.
Here’s my peanut butter cake recipe. I hope you love it as much as I do!
Peanut Butter Sheet Cake Recipe
- Preheat oven to 350º F. Prepare 18×13 rimmed baking sheet pan with nonstick baking spray or by buttering and lightly flouring the pan, ensuring that the pan is well-coated and discarding any excess flour.
- Add butter, water, and peanut butter to a medium-size saucepan over medium heat. Stirring frequently, bring to a boil. Remove from heat. Whisk in flour, sugar, salt and baking soda until just combined. Add in eggs, vanilla and buttermilk. Pour into prepared sheet pan and bake 20 minutes, or until the cake springs back to the touch and a toothpick when inserted into the center comes out clean.
