How to Make Peanut Butter Banana Cake Recipe
Step 1: Prepare the Cake Batter
Start by preheating your oven to 350°F (175°C) and greasing a 9×13-inch baking dish or lining it with parchment paper to ensure your cake comes out effortlessly. In a medium bowl, whisk together the flour, baking powder, baking soda, and salt—this dry mix sets the groundwork for the perfect rise and texture.
Step 2: Cream Butter, Peanut Butter, and Sugars
In a large bowl, cream together the softened butter, peanut butter, granulated sugar, and brown sugar until your mixture is light and fluffy. This step is essential for trapping air, which contributes to the cake’s tender crumb and its delightful peanut butter flavor.
Step 3: Add Eggs and Vanilla
Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Then, mix in the vanilla extract. These ingredients bring richness and an aromatic lift that ties all the flavors together beautifully.
Step 4: Incorporate the Bananas
Fold the mashed bananas into the wet mixture until fully combined. Their natural sweetness and moisture are what make this cake incredibly soft and flavorful, giving each slice that signature banana allure.
Step 5: Combine Dry Ingredients and Buttermilk
Gradually add the dry ingredients to the wet mixture, alternating with the buttermilk, starting and ending with the dry ingredients. Mixing just until combined keeps the cake tender and prevents it from becoming dense or tough.
Step 6: Bake the Cake
Pour the batter evenly into your prepared pan and smooth the top with a spatula. Bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean. The aroma filling your kitchen at this point is pure bliss.
Step 7: Cool the Cake
Let the cake cool completely in the pan before frosting. This step ensures the frosting will spread smoothly without melting and sliding off.
Step 8: Make the Peanut Butter Frosting
Beat together softened butter and peanut butter until smooth and creamy. Then, gradually add powdered sugar, mixing thoroughly after each addition. Finish with heavy cream and vanilla extract, whipping until the frosting is light, fluffy, and perfectly spreadable.
Step 9: Assemble and Garnish
Spread the luscious peanut butter frosting evenly over the cooled cake. Garnish with sliced bananas, crushed peanuts, and a drizzle of melted chocolate or peanut butter for an extra decadent touch that will impress anyone who tries it.
How to Serve Peanut Butter Banana Cake Recipe
Garnishes
A simple topping can take this cake from delightful to show-stopper. I love adding fresh sliced bananas and a sprinkle of crushed peanuts for crunch. A drizzle of melted chocolate or extra peanut butter adds a glossy finish that feels extra special.
Side Dishes
This cake pairs wonderfully with a scoop of vanilla ice cream or a dollop of whipped cream, which complement the peanut butter’s richness and the cake’s moist texture. For a cozy touch, enjoy it with a hot cup of coffee or chai tea that balances the sweetness perfectly.
Creative Ways to Present
For an unexpected twist, try cutting the cake into small squares and serving them on individual dessert plates with a drizzle of caramel sauce. You can also layer it in a trifle bowl with whipped cream and bananas for a stunning celebration dessert.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, keep them in an airtight container at room temperature for up to two days to maintain freshness. For longer storage, refrigerate the cake where it can stay good for about 4 to 5 days. Remember to bring it to room temperature or warm it slightly before serving for that fresh-baked appeal.
Freezing
This Peanut Butter Banana Cake Recipe freezes beautifully. Wrap individual slices tightly in plastic wrap and place them in a freezer-safe bag or container. They can be frozen for up to 3 months, making it convenient to enjoy your favorite cake anytime cravings hit.
Reheating
To enjoy frozen cake slices, simply thaw at room temperature or warm gently in the microwave for 15 to 20 seconds. This quick reheat revives the softness and gooey peanut butter flavors as if it were freshly baked.
FAQs
Can I use natural peanut butter instead of creamy?
Yes, you can! Just keep in mind that natural peanut butter may have a slightly different texture and oil content, which could affect the cake’s moisture and frosting consistency. Stir well before measuring, and you might need to adjust the frosting with a little more powdered sugar or cream.
What if I don’t have buttermilk on hand?
No worries! You can make a quick buttermilk substitute by mixing ½ cup of milk with 1 teaspoon of lemon juice or white vinegar. Let it sit for 5 minutes, and it’s ready to use. This substitution ensures your cake remains tender and moist.
How ripe should the bananas be?
For the best flavor and texture, use bananas that are very ripe with plenty of brown spots. The riper the bananas, the sweeter and more flavorful your cake will be, plus they’ll mash easily into the batter.
Can I make this cake gluten-free?
Absolutely! Swap the all-purpose flour with a 1-to-1 gluten-free baking flour blend. Just check that the blend contains xanthan gum or similar stabilizers for the best texture. The cake might be slightly different in crumb but still delicious.
Is this cake suitable for freezing after frosting?
Yes, but for best results, freeze the unfrosted cake separately, then thaw and frost right before serving. If you freeze it frosted, let the cake thaw overnight in the fridge and allow it to come to room temperature before serving.
