Ingredients You’ll Need
These ingredients are simple yet essential, working together to create a cupcake with perfect texture, rich flavor, and a lovely golden color. Each component plays a special role—from the ripe bananas adding moisture and natural sweetness, to the creamy peanut butter creating a smooth, decadent frosting that complements the soft cake.
- 1 1/2 cups all-purpose flour: The sturdy foundation providing structure without weighing the cupcakes down.
- 1 tsp baking powder: Helps the cupcakes rise and become fluffy.
- 1/2 tsp baking soda: Enhances leavening and adds a slight tenderness.
- 1/4 tsp salt: Balances the sweetness and elevates other flavors.
- 1/2 cup unsalted butter, softened: Adds richness and a tender crumb.
- 1 cup granulated sugar: Sweetens and helps achieve a golden crust.
- 2 large eggs: Bind everything together and add moisture.
- 1 tsp vanilla extract: Infuses warmth and depth of flavor.
- 2 ripe bananas, mashed: The star ingredient adding natural sweetness and moisture.
- 1/2 cup sour cream or buttermilk: Introduces a subtle tang and ensures a moist texture.
- 1/2 cup creamy peanut butter: For a luscious frosting with that classic nutty richness.
- 1/2 cup powdered sugar: Sweetens and thickens the frosting to just the right consistency.
- 1/4 cup unsalted butter, softened: Creates a smooth, creamy base for the frosting.
- 1/2 tsp vanilla extract: Compliments the peanut butter with a touch of fragrant sweetness.
- 1 tbsp milk (or more for desired consistency): Adjusts the frosting texture to be perfectly spreadable.
- 1/2 cup caramel sauce (store-bought or homemade): Adds gooey, indulgent sweetness for drizzling on top.
How to Make Banana Caramel Peanut Butter Cupcakes Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). Line a 12-cup muffin tin with cupcake liners or grease it well. This step ensures your cupcakes bake evenly and come out effortlessly.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Combining these dry ingredients separately helps distribute the leavening agents evenly for a perfect rise in your cupcakes.
Step 3: Cream Butter and Sugar
Using a hand mixer or stand mixer, beat the softened butter and granulated sugar together until light and fluffy, about 3 to 5 minutes. This process incorporates air into the batter, which creates a tender crumb texture in the finished cupcakes.
Step 4: Add Eggs and Vanilla
Beat in the eggs one at a time, making sure each is fully incorporated before adding the next. Then, mix in the vanilla extract. This step ensures a rich, well-rounded flavor and emulsifies the batter beautifully.
Step 5: Incorporate Bananas and Sour Cream
Fold in the mashed ripe bananas and sour cream (or buttermilk) to the wet ingredients. The bananas bring natural sweetness and moisture, while the sour cream adds a slight tang and tenderizes the crumb.
Step 6: Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet mixture, gently folding until just combined. Be careful not to overmix; a few lumps are okay. This preserves a light and fluffy cupcake texture.
Step 7: Bake the Cupcakes
Divide the batter evenly among the 12 prepared cupcake liners. Bake for 18 to 22 minutes or until a toothpick inserted into the center comes out clean. Allow the cupcakes to cool completely on a wire rack before frosting.
Step 8: Prepare the Peanut Butter Frosting
In a large bowl, beat the softened butter and creamy peanut butter together until smooth and fluffy. Gradually add powdered sugar, then vanilla extract and milk, adjusting the milk amount to achieve your preferred consistency. This frosting should be rich, creamy, and perfectly spreadable.
Step 9: Frost and Drizzle
Once the cupcakes are completely cooled, generously frost each one with the peanut butter frosting. Finally, drizzle caramel sauce over the cupcakes for a gooey and irresistible finish.
How to Serve Banana Caramel Peanut Butter Cupcakes Recipe

Garnishes
For an extra special touch, sprinkle chopped peanuts or a pinch of sea salt on top of the caramel drizzle. These little details add delightful texture and enhance the salty-sweet flavor profile that makes this Banana Caramel Peanut Butter Cupcakes Recipe truly stand out.
Side Dishes
Serve your cupcakes with a cold glass of milk, a cup of strong coffee, or even a scoop of vanilla ice cream. These pairings complement the richness of the cupcakes and balance the sweetness perfectly, turning any simple gathering into a cozy celebration.
Creative Ways to Present
Try placing each cupcake in a small, decorative cupcake wrapper or use edible gold leaf for a glamorous presentation. You can also pipe the peanut butter frosting with a star tip to create elegant swirls or make mini versions for bite-sized treats—either way, presentation adds magic to this Banana Caramel Peanut Butter Cupcakes Recipe.
Make Ahead and Storage
Storing Leftovers
Store leftover cupcakes in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days to keep the frosting fresh and maintain moisture in the cake.
Freezing
You can freeze unfrosted cupcakes by wrapping them tightly in plastic wrap and placing them in a freezer-safe bag or container for up to 3 months. For frosted cupcakes, freeze them uncovered on a baking sheet first, then wrap tightly to prevent frosting damage.
Reheating
To enjoy frozen or refrigerated cupcakes, let them thaw at room temperature, then warm briefly in the microwave for about 10-15 seconds if you prefer a softer, cake-fresh experience—careful not to melt the frosting!
FAQs
Can I use natural peanut butter for the frosting?
Yes, natural peanut butter works well, but since it tends to be thinner and oilier, you might need to adjust the powdered sugar and milk to get the right frosting consistency.
What if I don’t have sour cream or buttermilk?
You can substitute with plain yogurt or make a buttermilk substitute by mixing 1/2 cup milk with 1/2 teaspoon lemon juice or vinegar, then letting it sit for 5 minutes before using.
How ripe should the bananas be?
For the best flavor and moisture, use bananas that are very ripe with plenty of brown spots. The softer and sweeter they are, the more flavorful your cupcakes will be.
Can I make this recipe gluten-free?
Absolutely! Swap the all-purpose flour for a gluten-free baking flour blend that includes xanthan gum, and you should get nearly identical texture and taste.
Is it possible to make the caramel sauce from scratch?
Yes, homemade caramel sauce can elevate this recipe even further. Simply melt sugar until golden, add butter and cream, then stir until smooth and thickened. Use it warm or at room temperature for drizzling.
