  • 3 large eggs
  • ½ cup buttermilk
  • 1 teaspoon baking soda
  • 1 teaspoon baking powder

  • 1 teaspoon vanilla extract

For the frosting:

  • 1 cup creamy peanut butter
  • 4 cups powdered sugar
  • ½ cup unsalted butter, softened
  • 3 tablespoons milk
  • ½ teaspoon vanilla extract

Step-by-Step Instructions

  1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, ready to embrace the magic!
  2. Cream Together the Butter and Peanut Butter: In a large mixing bowl, combine the softened butter and creamy peanut butter. Beat on medium speed until smooth and fluffy.
  3. Add Sugar and Eggs: Gradually add granulated sugar while continuing to beat. Once combined, add in the eggs one at a time—mixing thoroughly after each addition.
  4. Combine Dry Ingredients: In another bowl, whisk together flour, baking soda, baking powder, and salt to create a dry mixture.

  8. Make the Frosting: In a medium bowl, combine the softened butter, peanut butter, and powdered sugar. Add milk and vanilla extract, whipping until the mixture reaches a smooth and creamy frosting consistency.

What to Serve The Ultimate Peanut Butter Cake With

Pair your peanut butter cake with a scoop of vanilla ice cream or a dollop of whipped cream to balance the richness of the flavors.

And don’t shy away from enjoying this cake with a steaming cup of coffee or a glass of cold milk—who could resist the perfect dessert duo?

Top Tips for Perfecting The Ultimate Peanut Butter Cake

  • Ingredient Substitutions: If you’re out of buttermilk, a quick substitute is to mix regular milk with a tablespoon of vinegar or lemon juice; let it sit for about 5 minutes before using.
  • Timing Adjustments: Each oven is unique—be sure to check the cakes a few minutes before the 30-minute mark to avoid overbaking.
  • Avoid Common Mistakes: Ensure all ingredients are at room temperature for better mixing and a smooth batter.

Storing and Reheating Tips

To store any leftover cake, wrap it tightly with plastic wrap or place it in an airtight container at room temperature for up to 3 days. If you want to keep it longer, it can be refrigerated for up to a week. To reheat, simply slice a piece and warm it in the microwave for about 10-15 seconds or until it’s just warm—perfect for those moments when you crave a sweet treat.
