Before You Get Started: A couple notes to help you get the best results
How To Make Peanut Butter Cake
- Preheat the oven to 350 degrees Fahrenheit.
- Spray 2 8-inch round cake pans or a 9×13-inch cake pan with non-stick spray.
- In a mixing bowl, combine both sugars and vegetable oil. Mix on high for 3 minutes.
- Mix in vanilla extract and add eggs one at a time.
- Mix in milk and yogurt.
- In a separate bowl, combine all dry ingredients and mix well.
- Add the wet ingredients to the dry mixture and mix until incorporated.




- Pour the cake batter into the prepared baking pans.
- Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. Check closer to the 25-minute mark to prevent overbaking.


- Remove from the oven and allow to cool completely before frosting.
- In a mixing bowl, combine butter, peanut butter, vanilla extract, 4 cups of powdered sugar, and 2 tbsp of heavy cream.

- Mix until smooth.
- Adjust consistency: If the frosting is too stiff, add more heavy cream 1 tbsp at a time. If it’s too thin, add another cup of powdered sugar.
- Once the cake has cooled completely, frost it with the peanut butter frosting.
- If making a 4-layer cake, double the frosting recipe or cut the cake layers in half horizontally with a cake leveler or cake knife before frosting.



- Once frosted, enjoy!
Variations & Substitutions
- Chocolate Swirl: Craving a chocolate and peanut butter combo? Fold in some chocolate chips or a swirl of melted chocolate into the batter for a decadent twist. Top it with a chocolate ganache for an extra dose of deliciousness.
- Fruity Fun: Love a sweet and salty combo? Fresh fruit like sliced bananas or chopped berries can add a pop of color and freshness. Layer them into the cake or use them to decorate the top.
- Nutella Dreams: Feeling adventurous? Replace some of the peanut butter in the frosting or filling with Nutella for a rich, hazelnutty flavor that complements the peanut butter beautifully.
- Frosting Frenzy: Don’t be afraid to experiment with different frostings! I have a Peanut Butter Cream Cheese Frosting, Peanut Butter Honey Cinnamon Frosting, and a Chocolate Frosting that would pair perfectly with this cake!
- Pretzel Power: Crush some pretzels and sprinkle them on top of the frosting for a salty-sweet crunch that complements the peanut butter perfectly.

Can I use crunchy peanut butter for the frosting?
You can, but keep in mind that the texture will be different. Smooth peanut butter creates a creamier frosting, while crunchy peanut butter adds a bit of texture.

To ensure even cake layers, use a kitchen scale to measure the batter equally between the pans. Also, rotating the pans halfway through baking can help them bake evenly.
