Pro Tips for the Best Peanut Butter Cake with Peanut Butter Frosting

1. Room Temperature Ingredients: Let butter, peanut butter, eggs, and buttermilk warm slightly before mixing for a smoother batter.
2. Alternate Wet and Dry Ingredients: This ensures the batter blends evenly without overmixing.
3. Test for Doneness Early: Oven temperatures vary, so start checking your cake a few minutes before the recommended time.
4. Cool Completely Before Frosting: Warm cake will cause frosting to melt and slide off.
5. Add Garnishes for Flair: Chopped peanuts, a drizzle of chocolate, or caramel can take the presentation to the next level.

Ingredients:

For the Peanut Butter Cake:

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

For the Peanut Butter Frosting:

• ½ cup unsalted butter, softened
• 1 cup creamy peanut butter
• 4 cups powdered sugar
• ¼ cup heavy cream
• 1 teaspoon vanilla extract
• Pinch of salt

Directions:

1. Prepare the Pans: Preheat your oven to 350°F. Grease and flour two 9-inch round cake pans or line them with parchment paper.
2. Cream the Butter and Sugars: In a large mixing bowl, beat the peanut butter, softened butter, granulated sugar, and brown sugar until light and fluffy, about 3–5 minutes.
3. Incorporate Eggs and Vanilla: Add eggs one at a time, mixing well after each addition. Stir in the vanilla extract until combined.
4. Combine Dry Ingredients: In a separate bowl, whisk together flour, baking powder, baking soda, and salt until well mixed.
5. Alternate Mixing: Gradually add the dry mixture to the peanut butter mixture, alternating with buttermilk. Begin and end with the dry mixture, mixing just until combined.
6. Fill and Smooth: Divide the batter evenly between the pans, smoothing the tops with a spatula. Tap gently to release air bubbles.
7. Bake the Cakes: Place in the oven for 25–30 minutes, or until a toothpick inserted into the center comes out clean. Tent with foil if the tops brown too quickly.
8. Cool the Layers: Let the cakes cool in their pans for 10 minutes, then transfer to wire racks to cool completely.
9. Make the Frosting: Beat the softened butter and peanut butter until smooth. Gradually add powdered sugar, one cup at a time, mixing after each addition.
10. Finish the Frosting: Add the heavy cream, vanilla extract, and pinch of salt. Beat until the frosting is light and fluffy. Adjust cream for desired consistency.
11. Assemble the Cake: Place one cooled cake layer on a serving plate. Spread a generous layer of frosting over the top. Position the second cake layer on top, then frost the top and sides until smooth.
12. Add Final Touches: Garnish with chopped peanuts or a drizzle of chocolate if desired.
