Perfect Chocolate Banana Cupcakes

If you want a chocolate cupcake that’s not overly rich but still full of flavor and wonderfully moist, these chocolate banana cupcakes are a perfect choice. Mashed banana keeps the crumb tender and adds a subtle banana note that complements the chocolate. The result is light, fluffy cupcakes with a soft texture—finished with smooth chocolate frosting for a double dose of chocolate.

This version is a dessert-like take on chocolate banana quick breads and muffins: lighter, a bit sweeter, and topped with frosting for extra indulgence. The combination of oil, brown and granulated sugar, mashed bananas, and milk creates a moist cake crumb without greasiness. You’ll end up with chocolate cupcakes that are tender and never dry.

Baking Tips

  • Use brown, spotted bananas for the best banana flavor and moisture.
  • This recipe calls for 2/3 cup mashed banana—about one very large banana or one and a half small bananas.
  • Dutch-processed cocoa gives a deeper chocolate flavor and darker color, but natural cocoa will also work.
  • The recipe yields about 14–16 cupcakes. Fill each lined muffin cup about 2/3 to 3/4 full—do not overfill.
  • If you prefer only a thin layer of frosting, consider making half the frosting batch to avoid excess.

Equipment

  • muffin tin

Ingredients

Chocolate Banana Cupcakes

  • 1 cup all-purpose flour (125 grams)
  • 1/2 cup cocoa powder (40 grams)
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 1/3 cup vegetable oil (80 ml)
  • 1/2 cup brown sugar (100 grams), light or dark
  • 1/2 cup granulated sugar (100 grams)
  • 2 large eggs, room temperature
  • 1 tsp vanilla extract
  • 2/3 cup mashed bananas (about 1 very large banana)
  • 1/3 cup milk (80 ml)

Chocolate Frosting

  • 1 cup unsalted butter (226 grams), softened
  • 3–4 cups powdered sugar (330–440 grams), sifted
  • 1/2 cup cocoa powder (40 grams), sifted
  • 1 tsp vanilla extract
  • 1/4 tsp salt
  • 4–6 tbsp whipping cream (60–75 ml) — milk can be used but frosting will be slightly thinner

Instructions

Make the Banana Chocolate Cupcakes

  • Preheat the oven to 350°F (180°C) and line muffin tins with paper liners. This makes about 14–16 cupcakes.
  • Whisk together flour, cocoa powder, baking powder, baking soda, and salt in a large bowl; set aside.
  • In another large bowl, whisk oil, brown sugar, granulated sugar, eggs, vanilla, and milk. Stir in the mashed banana.
  • Make a well in the dry ingredients and pour in the wet mixture. Gently whisk until no dry streaks remain; a few banana lumps are fine.
  • Spoon batter into liners, filling each about 2/3 to 3/4 full.
  • Bake one tray at a time on the middle rack for 16–18 minutes, or until a toothpick comes out clean or with a few moist crumbs.
  • Allow cupcakes to cool in the tin for at least 10 minutes, then transfer to a wire rack to cool completely before frosting.

Chocolate Frosting

  • Beat softened butter in a large bowl until fluffy.
  • On low speed, gradually beat in 2 cups of the powdered sugar.
  • Add the cocoa, salt, and vanilla. Start on low speed and increase gradually to combine.
  • Alternate adding the remaining powdered sugar about 1/2 cup at a time with 1 tablespoon whipping cream until you reach the desired sweetness and consistency.
  • Frost cupcakes with a piping bag (a 1M tip works well) or spread the frosting with a knife.

Notes

  1. Bananas: Use brown, spotted bananas for best flavor. One very large banana or one and a half smaller bananas yields about 2/3 cup mashed banana.
  2. Milk: 2% milk was used; 1% is acceptable. Avoid skim for best texture.
  3. Frosting: For a thin layer of frosting, make half the frosting recipe.
  4. Storage: Store frosted cupcakes in an airtight container at room temperature up to 3 days. Unfrosted cupcakes freeze up to 2 months; thaw overnight in the fridge.
  5. Nutrition: Values are estimates per cupcake, assuming 14 cupcakes and all frosting used.
