A Cake That Stands Out
In a world of chocolate overload and vanilla monotony, peanut butter cake brings something fresh and exciting to the table. It’s a flavor that surprises and delights, especially when paired with complementary ingredients like chocolate, banana, or even a swirl of caramel. And because peanut butter is naturally creamy and rich, the cake stays moist longer than many traditional recipes.

Serve it at a family dinner, bring it to a potluck, or surprise your coworkers—it’s always a hit. And if you’re looking for a fun twist, try turning it into cupcakes or cake pops for easy sharing.
Ingredients You’ll Need
The beauty of this peanut butter cake recipe is that it uses ingredients you likely already have in your pantry. No need for specialty flours or hard-to-find extracts. Here’s what you’ll need:
- All-purpose flour: The base of the cake, providing structure without weighing it down.
- Baking powder and baking soda: Leavening agents that help the cake rise and stay light.
- Salt: Enhances the peanut butter flavor and balances the sweetness.
- Unsalted butter and vegetable oil: Butter adds richness, while oil keeps the cake moist.
- Granulated and brown sugar: Brown sugar adds moisture and a subtle caramel note.
- Eggs: Bind the ingredients and add structure.
- Vanilla extract: Complements the peanut butter without overpowering it.
- Peanut butter: Use creamy, natural-style peanut butter for the best flavor and texture.
- Buttermilk: Adds tang and keeps the cake tender.
For the frosting, you’ll need powdered sugar, more peanut butter, softened butter, and a splash of milk or cream to reach the perfect spreading consistency.
Choosing the Right Peanut Butter
Not all peanut butters are created equal. For this cake, avoid overly sweet or oily varieties. Look for a natural peanut butter with minimal ingredients—just peanuts and maybe a little salt. Brands like Jif or Skippy work well if you prefer a smoother texture, but natural options like Smucker’s Natural or Trader Joe’s are excellent choices too. Just make sure it’s well-stirred and at room temperature before using.
Step-by-Step Instructions
Ready to bake? This peanut butter cake comes together in just a few simple steps. Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans. Line the bottoms with parchment paper for easy removal.
Make the Batter
In a large mixing bowl, cream together the softened butter, oil, granulated sugar, and brown sugar until light and fluffy—about 3–4 minutes with a hand mixer. Add the eggs one at a time, mixing well after each. Stir in the vanilla and peanut butter until smooth.
In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, alternating with the buttermilk. Begin and end with the dry ingredients, mixing just until combined. Be careful not to overmix—this keeps the cake tender.
Bake to Perfection
Divide the batter evenly between the prepared pans. Smooth the tops with a spatula. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes, then turn them out onto a wire rack to cool completely before frosting.
Make the Frosting
While the cakes cool, prepare the frosting. In a medium bowl, beat the softened butter and peanut butter until smooth. Gradually add the powdered sugar, mixing on low speed to avoid a sugar cloud. Add a splash of milk or cream and beat until fluffy and spreadable. If it’s too thick, add more milk; if too thin, add more powdered sugar.
Assemble the Cake
Place one cake layer on a serving plate or cake stand. Spread a generous layer of frosting on top. Add the second layer and frost the top and sides of the cake. For a professional touch, use a piping bag to create swirls or rosettes on top. Sprinkle with chopped peanuts or chocolate shavings if desired.
Tips for the Best Peanut Butter Cake
Even the best recipes can benefit from a few pro tips. Here’s how to make sure your cake turns out perfect every time:
- Use room temperature ingredients: This ensures even mixing and a smoother batter.
- Don’t overmix: Once you add the flour, mix just until combined to avoid a dense cake.
- Check for doneness early: Ovens vary, so start checking at 25 minutes to prevent overbaking.
- Let cakes cool completely: Warm cake will melt the frosting and make assembly messy.
- Store properly: Keep the cake covered at room temperature for up to 3 days or refrigerate for up to a week.
Make-Ahead and Freezing Tips
This cake actually tastes even better the next day, as the flavors meld together. You can bake the layers a day ahead and store them wrapped in plastic wrap at room temperature. Frost just before serving for the freshest taste.
Want to plan ahead? The baked and cooled cake layers freeze beautifully. Wrap them tightly in plastic wrap and then foil, and freeze for up to 3 months. Thaw overnight in the fridge before frosting.
Creative Variations and Add-Ins
Once you’ve mastered the classic version, feel free to get creative! Here are a few fun twists to try:
- Chocolate swirl: Melt 1/2 cup of chocolate chips and swirl into the batter before baking.
- Banana peanut butter cake: Add 1 mashed ripe banana to the batter for extra moisture and flavor. Pair with our banana peanut butter muffins for a themed dessert spread.
- Peanut butter cup topping: Press mini peanut butter cups into the frosting for a fun, crunchy surprise.
- Cupcake version: Pour the batter into lined muffin tins and bake for 18–20 minutes. Perfect for parties!
- Cookie cake hybrid: Bake in a 9×13-inch pan and top with crushed Nutter Butter cookies for a fun texture contrast.
And if you’re a fan of no-bake desserts, consider pairing this cake with a scoop of gooey butter cake ice cream for an indulgent treat.
Serving and Storing Your Cake
This peanut butter cake is best served at room temperature, where the frosting is soft and the cake is tender. Use a sharp knife to cut clean slices—dipping the knife in hot water and wiping it between cuts helps.
Store any leftovers in an airtight container. At room temperature, it stays fresh for up to 3 days. For longer storage, refrigerate for up to a week. You can also freeze individual slices wrapped in plastic wrap for up to 2 months—perfect for quick desserts later.
Pairing Suggestions
Serve this cake with a glass of cold milk, a cup of coffee, or even a scoop of vanilla ice cream. The creamy peanut butter pairs wonderfully with the cold, sweet contrast of ice cream. For a festive touch, add a drizzle of chocolate sauce or caramel on top.

Frequently Asked Questions
Can I use crunchy peanut butter in this cake?
Yes, you can! Crunchy peanut butter adds a fun texture, but it may make the cake slightly denser. For the best results, use creamy peanut butter in the batter and reserve crunchy for the frosting or topping.
Can I make this cake gluten-free?
Absolutely. Substitute the all-purpose flour with a 1:1 gluten-free flour blend. Make sure all other ingredients, like baking powder, are certified gluten-free.
How do I prevent the cake from sticking to the pan?
Always grease your pans and line the bottoms with parchment paper. Let the cakes cool for 10 minutes before turning them out—this helps release them cleanly.
Can I make this cake in a sheet pan?
Yes! Use a 9×13-inch baking pan and adjust the baking time to 20–25 minutes. This version is great for larger groups and easier to frost.
What if I don’t have buttermilk?
No problem. Make a quick substitute by mixing 1 cup of milk with 1 tablespoon of lemon juice or vinegar. Let it sit for 5 minutes before using.
Can I freeze the frosted cake?
It’s best to freeze unfrosted layers. Frosting can become grainy when frozen and thawed. Freeze the layers, then thaw and frost when ready to serve.
