Ingredients

How To Make Chocolate Banana Cupcakes Step by Step

Make Quick Buttermilk

Preheat your baking oven to 350°F (175°C) and line a 12-cup muffin pan with paper liners. In a measuring cup, combine ¾ cup milk and 1 Tablespoon vinegar, then let sit for 5 minutes until curdled.

Blend the Wet Base

In a large bowl, mash the 2 bananas until completely smooth. Whisk in the 1 cup granulated sugar, ¼ cup vegetable oil, 1 egg, 1 teaspoon vanilla extract, and the prepared milk and vinegar mixture until smooth.

Sift Dry Ingredients

In a separate medium bowl, sift together the 1¼ cup all-purpose flour, ¼ cup cocoa powder, ¾ teaspoon baking soda, and ½ teaspoon salt to remove any cocoa lumps.

Combine the Batter

Gently add the sifted dry ingredients into the wet bowl. Whisk smoothly just until the dry flour spots disappear into a thin, chocolatey, fragrant batter.

Fill and Bake

Divide the smooth batter evenly among your 12 lined cups, filling each paper liner about two-thirds of the way full. Bake at 350°F for 18 to 20 minutes until a toothpick inserted in the center comes out clean.

Cool Completely

Remove the baking tray from the oven and let the cupcakes sit in the pan for 5 minutes. Transfer them onto a wire cooling rack to cool completely before decorating.

Tips For The Best Chocolate Banana Cupcakes

• Use Very Ripe Fruit: Choose fruit covered in dark brown spots for your mash to ensure maximum natural sweetness and moisture in the batter.
• Don’t Skip the Vinegar: Combining the 1 Tablespoon vinegar with ¾ cup milk creates an acidic base that activates the baking soda for a fluffy rise.
• Sift the Cocoa Powder: Always sift your ¼ cup cocoa powder with the flour to prevent stubborn bitter dry lumps in your smooth batter.
• Avoid Overfilling Cups: Fill paper liners no more than two-thirds full so the rising cocoa tops form pretty, flat domes without spilling over.
• Cool Before Frosting: Ensure your baked treats are 100% cool to room temperature on a wire rack before piping any sweet toppings on top.

Variations

• Fast Banana Cupcakes Easy Option: Skip complex piped frosting and simply dust the cooled tops with powdered sugar for a quick Banana Cupcakes Easy treat.

Storage Instructions

• Counter: Keep unfrosted baked treats stored inside an airtight container at room temperature for up to 3 days to keep the crumb soft.
• Fridge: Store frosted or unfrosted cakes inside an airtight container in the refrigerator for up to 5 days for a cool bite.
• Freezer: Wrap individual cooled, unfrosted cakes tightly in plastic wrap and freeze inside a heavy-duty bag for up to 2 months.
• Reheat: Warm an unfrosted chilled treat in the microwave for 8 to 10 seconds to make the chocolate crumb tender and fragrant again.

Serving and Pairing Ideas

• Serve a fresh room-temperature treat with a cold glass of whole dairy milk, oat milk, or creamy almond milk.
• Pair your sweet afternoon dessert with a hot mug of decaf black coffee, a warm espresso, or a steaming cup of herbal tea.
• Serve alongside a scoop of classic vanilla bean ice cream or chocolate ice cream for a delicious birthday dessert plate.

Frequently Asked Questions

Can I make buttermilk substitutes if I don’t have vinegar?

Yes, if you do not have white vinegar on hand, you can substitute an equal amount of fresh lemon juice combined with the ¾ cup of milk. The acid in the lemon juice reacts identically with the milk, creating that essential sour base that tenderizes the wheat flour and activates the ¾ teaspoon of baking soda for a light, airy rise.

Why did my cupcakes sink in the middle after baking?

Cupcakes usually sink in the middle if the baking soda was expired, if the batter was overmixed, or if the oven door was opened too early during baking. To ensure an even dome, gently fold the dry ingredients until just combined, and keep the oven door closed for at least the first 15 minutes of baking time.

Can I substitute melted butter for the vegetable oil?

Yes, you can substitute the ¼ cup of vegetable oil with an equal amount of melted unsalted butter if you prefer a richer, buttery flavor profile. However, using vegetable oil keeps the chocolate and fruit sponges exceptionally moist and soft even after being stored in the refrigerator.

How do I stop the paper liners from peeling away from the cakes?

Paper liners peel away when moisture gets trapped between the paper and the cake during cooling. To prevent peeling, remove the baked cakes from the warm metal pan after 5 minutes and let them cool completely on an open wire rack so steam can escape freely.
