Ingredients
- 1 3/4 cups all-purpose flour
The cornerstone of any cake, all-purpose flour provides structure and stability. It helps the cake rise and gives it a tender crumb when combined with other ingredients. - 1 cup sugar
Sugar adds sweetness and helps create a moist cake by retaining moisture during baking. It also plays a key role in browning the cake to a lovely golden hue. - 1/2 cup creamy peanut butter
This is the star ingredient that imparts a rich, nutty flavor. Peanut butter also contributes to the cake's moisture and texture. - 1/2 cup unsalted butter, softened
Butter adds richness and flavor to the cake while helping to create a tender crumb through its ability to trap air during mixing. - 3 large eggs
Eggs act as a binding agent, providing structure and stability. They also add moisture and contribute to the cake's overall height. - 1 teaspoon baking powder
This leavening agent helps the cake rise by producing carbon dioxide when exposed to moisture and heat, giving the cake a light and fluffy texture. - 1/2 teaspoon baking soda
Baking soda is essential for creating a balanced pH in the batter, which affects the cake’s texture and helps it to rise. - 1/2 teaspoon salt
Salt enhances the overall flavor profile, balancing the sweetness of the cake while strengthening the structure of the batter. - 1 cup buttermilk
Buttermilk introduces acidity that reacts with the baking soda to create a light cake. It also adds moisture and a slight tanginess. - 2 cups powdered sugar
Powdered sugar is used for the frosting, providing sweetness while allowing for a smooth, creamy texture without the graininess of granulated sugar. - 1/2 cup creamy peanut butter (for frosting)
Just like in the cake, peanut butter in the frosting adds deep flavor, creaminess, and pairs beautifully with the sweet notes from the powdered sugar. - 2 tablespoons milk or cream (for frosting)
Milk or cream ensures the frosting is spreadable while adding richness and a smooth texture that perfectly coats the cake.
Directions & Preparation
Step 1: Preheat your oven to 350°F (175°C).
Preheating the oven is crucial for ensuring even baking. If the oven isn't hot enough, the cake may not rise properly, affecting its texture and structure.
Step 2: Grease and flour two 9-inch round cake pans.
Properly preparing the pans prevents the cake from sticking, which can ruin its shape and presentation. Grease ensures the pan is coated, while flour creates a protective barrier.
Step 3: In a large mixing bowl, cream the butter and sugar until light and fluffy.
Creaming the butter and sugar together incorporates air into the mixture, which is essential for creating a light and airy cake. Aim for a pale, fluffy texture to ensure optimal results.
Step 4: Add the peanut butter and blend thoroughly.
Incorporating peanut butter into the creamed mixture adds flavor and moisture, contributing to the cake's overall richness. Make sure it is well-blended to avoid clumps.
Step 5: Add eggs one at a time, mixing well after each addition.
Adding eggs gradually allows for better emulsification, which is key in achieving a smooth batter. Ensure each egg is fully incorporated before adding the next.
Step 6: In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
This step ensures that the leavening agents are evenly distributed throughout the flour, leading to consistent rising and texture in the baked cake.
Step 7: Alternately add the dry ingredients and buttermilk to the butter mixture, starting and ending with dry ingredients. Mix until just combined.
Mixing in alternating batches allows for easier incorporation and prevents overmixing. Overmixing can lead to a dense cake, so stop as soon as the ingredients are blended.
Step 8: Divide the batter evenly between the prepared pans and smooth the tops.
Ensuring an even distribution of batter helps the cakes bake uniformly, contributing to a consistent texture and height in the finished layers.
Step 9: Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
Baking time is crucial for the perfect cake. Toothpick tests help determine doneness; it should come out clean or with a few crumbs attached, indicating the cakes are moist but fully cooked.
Step 10: Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
Allowing the cakes to cool slightly in the pans helps prevent them from breaking apart when moved. Transferring to a wire rack lets air circulate, preventing sogginess.
Step 11: While the cake cools, make the frosting by beating peanut butter and butter until smooth.
Starting with softened butter creates a creamy base for your frosting. Beating thoroughly ensures the ingredients are well-combined, resulting in a silky texture.
Step 12: Gradually add powdered sugar and milk, mixing until frosting reaches desired consistency.
Adding powdered sugar gradually allows control over sweetness and texture. If the frosting is too thick, a splash of milk can help achieve the perfect spreadable consistency.
Step 13: Once the cakes are completely cool, place one layer on a serving plate and spread frosting on top.
Spreading frosting on the first layer creates a delicious, smooth base. An even layer ensures that the second cake sits flat, preventing any slippage.
Step 14: Top with the second layer and frost the top and sides of the cake.
Frosting the sides not only enhances presentation but also creates a delicious chocolate buttercream barrier that holds in the moisture of the cake. Take your time to make it look nice.
Step 15: Decorate as desired, with leftover frosting or peanuts on top.
Finishing touches can elevate the cake, so don’t hesitate to get creative with decoration. Chopped peanuts add texture and a visual appeal, making your dessert irresistible.
Step 16: Slice and serve your delightful Peanut Butter Cake!
Finally, the most rewarding step! Serving allows everyone to enjoy the work that went into this cake. Each slice reveals the rich layers and creamy frosting, ready to be devoured.

The Rich History of Peanut Butter Cake
Peanut butter cake is not just a modern culinary invention; its roots can be traced back to the availability of peanut butter in the early 1900s. As more households began to use this versatile spread, creative bakers started to incorporate it into desserts. This cake pays homage to that tradition, blending classic baking methods with the beloved flavor of peanut butter, creating an enduring favorite in American cuisine.
Tips for the Perfect Peanut Butter Frosting
Achieving the ideal peanut butter frosting involves balancing richness and sweetness. Start by ensuring your ingredients are at room temperature to achieve a smooth texture. If your frosting feels too thick, add milk a tablespoon at a time until you reach your preferred consistency. For a flavor boost, consider adding a teaspoon of vanilla extract, which enriches the overall taste profile.
Pairing Suggestions for Your Peanut Butter Cake
This Peanut Butter Cake is delicious on its own, but it can be elevated with a few thoughtful pairings. A scoop of vanilla ice cream complements the richness of the cake beautifully, while a drizzle of chocolate sauce adds a decadent touch. For a refreshing contrast, serve it with fresh fruit like banana slices or a berry medley, enhancing both flavor and presentation.
FAQs
What should I do if my cake turns out too dense?
A dense cake can result from overmixing the batter. Ensure you mix until just combined and avoid beating too long after adding the dry ingredients.
Can I substitute natural peanut butter in this recipe?
Yes, but natural peanut butter has a different texture and oil separation, which might change the consistency of your batter and frosting. If used, stir it thoroughly before measuring.
Why is my frosting too runny?
If your frosting is too thin, gradually add more powdered sugar until it reaches the desired consistency. Avoid adding too much liquid initially to maintain thickness.
Can I use this recipe for cupcakes instead of a cake?
Absolutely! This recipe can be adapted for cupcakes; simply reduce the baking time to about 15-20 minutes and check for doneness with a toothpick.
Is it possible to make this cake in one large pan?
Yes, you can bake it in a 9×13 inch pan. Just increase the baking time slightly and monitor closely until a toothpick comes out clean.
How do I know when my cake is done baking?
Check for doneness by inserting a toothpick in the center; it should come out clean or with just a few crumbs attached, indicating the cake is moist yet cooked.
