Ingredients

For the Cake

• 2 cups all-purpose flour
• 1 teaspoon baking powder
• 1 teaspoon baking soda
• ½ teaspoon salt
• 1 cup unsalted butter, softened
• 1 cup granulated sugar
• 1 cup packed brown sugar
• 4 large eggs
• 1 cup smooth peanut butter
• 1 teaspoon vanilla extract
• 1 cup buttermilk

For the Frosting

• 1 cup unsalted butter, softened
• 2 cups creamy peanut butter
• 3 cups powdered sugar
• ¼ cup heavy cream (adjust to achieve desired consistency)

Optional Substitutions

• Allergy-friendly: Substitute almond butter or sunflower seed butter for peanut butter.
• Dairy-free: Replace buttermilk with plant-based milk mixed with 1 tablespoon lemon juice; use a dairy-free butter and cream substitute for the frosting.

Instructions

Step 1 — Preheat the Oven

Preheat the oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment paper for easy removal.

Step 2 — Prepare the Dry Ingredients

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.

Step 3 — Cream the Butter and Sugars

In a large mixing bowl, beat the softened butter with the granulated sugar and brown sugar until the mixture is light and fluffy.

Step 4 — Add Eggs and Peanut Butter

Add the eggs one at a time, beating until each is incorporated. Mix in the peanut butter and vanilla until the batter is smooth and even.

Step 5 — Combine Wet and Dry Ingredients

Alternately add the dry ingredients and the buttermilk to the butter mixture, beginning and ending with the dry ingredients. Mix only until combined to avoid a dense cake.

Step 6 — Bake the Cake Layers

Divide the batter evenly among the prepared pans. Smooth the tops and bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.

Step 7 — Cool the Cakes

Allow the cakes to cool in the pans for about 10 minutes, then transfer them to a wire rack. Let them cool completely before frosting.

Step 8 — Make the Frosting

Beat the softened butter and peanut butter together until creamy. Gradually add the powdered sugar, about one cup at a time, beating until smooth. Add heavy cream slowly until you reach a spreadable consistency.

Step 9 — Assemble and Frost

Place one layer on your serving plate and spread a generous layer of frosting. Repeat with remaining layers. Use the remaining frosting to cover the sides and top, then decorate as desired with crushed nuts or a drizzle of chocolate.

Notes & Tips

• Use room-temperature ingredients: Let butter, eggs, and buttermilk come to room temperature for a smoother, more even batter.
• Don’t overmix: Mix only until ingredients are combined; overmixing develops gluten and can make the cake heavy.
• Adjust frosting consistency: If frosting is too thick, add a splash more cream. If too thin, add powdered sugar a little at a time.
• Even baking: Rotate pans halfway through baking for uniform color and doneness.
• Even layers: For uniform layer height, weigh the batter into each pan using a kitchen scale.
• Decoration ideas: Top with crushed peanuts, toasted coconut, chocolate shavings, or a chocolate drizzle for extra contrast and texture.

Serving Suggestions

This cake pairs beautifully with a cold glass of milk, a handful of fresh berries for brightness, or a hot cup of coffee or tea for a decadent afternoon treat.

Frequently Asked Questions

Can I use chunky peanut butter instead of smooth?

Yes. Chunky peanut butter will add texture and crunch to the cake and frosting, but it may alter the smoothness of both the batter and frosting.

How can I make this cake gluten-free?

Use a certified gluten-free all-purpose flour blend that contains a binder such as xanthan gum. Check that other ingredients are gluten-free.

Can I bake the layers ahead of time?

Absolutely. You can bake the layers a day in advance, wrap them well, and frost before serving. Layers can also be frozen for longer preparation.

What other frostings pair well with this cake?

Chocolate ganache, cream cheese frosting, or a salted caramel buttercream all pair wonderfully with peanut butter for a balanced flavor profile.
