3-Ingredient Chocolate Banana Muffins

3-Ingredient Chocolate Banana Muffins turn overripe bananas into a rich, fudgy little treat with almost no effort. Mashed banana brings natural sweetness and moisture, cocoa powder adds deep chocolate flavor, and juicy blueberries brighten every bite. There’s no flour, eggs, butter, or dairy—just three simple ingredients and one bowl.

These aren’t traditional fluffy bakery muffins, and that’s part of their charm. The texture is soft, dense, and brownie-like, especially once the muffins have cooled completely. They’re easy enough for a quick breakfast or snack, but chocolatey enough to feel like dessert. Better yet, the batter comes together in minutes, making this a great recipe for those extra-ripe bananas sitting on the counter. Simple ingredients, very little cleanup, and a batch of chocolate banana muffins ready in about half an hour.

Recipe Yield: 6 muffins

INGREDIENTS

1 cup mashed very ripe banana (about 2 large bananas)
⅓ cup unsweetened cocoa powder
⅔ cup fresh blueberries (or frozen, unthawed)

INSTRUCTIONS

1. Preheat & prep:
Preheat the oven to 350°F. Line 6 cups of a standard muffin tin with parchment-style or silicone liners, or lightly grease the muffin cups.

2. Mix the batter:
Mash the banana until completely smooth. Sift in the cocoa powder and stir until smooth and evenly combined. Then, gently fold in the blueberries, keeping them whole.

3. Fill the cups:
Divide the batter evenly among the 6 prepared muffin cups. Gently tap the pan on the counter to settle the batter.

4. Bake until set:
Bake for 22–25 minutes, or until the tops look set, the edges feel firm, and the centers no longer jiggle. A toothpick inserted into the chocolate portion of a muffin, avoiding a blueberry, may have a few moist crumbs but should not have wet batter.

5. Cool completely:
Let the muffins cool in the pan for 10 minutes, then transfer them to a wire rack. Allow them to cool completely before removing the liners—the muffins firm up as they cool and develop their best fudgy texture.

Helpful Tips to Perfect This Recipe

• Measure the mashed banana: Use a full 1 cup rather than relying only on the number of bananas. Too much banana can make these flourless muffins overly soft.
• Keep the blueberries whole: Fold them in gently instead of crushing or blending them. This gives you juicy berry pockets without adding unnecessary moisture throughout the batter.
• Watch for visual doneness: Because these muffins contain no flour or eggs, the toothpick test alone can be misleading. Look for set tops, firm edges, and centers that no longer jiggle.
• Give them time to cool: These muffins are delicate while warm but become noticeably firmer once completely cooled. If using frozen blueberries, they may need an extra 1–3 minutes in the oven.
• Expect a fudgy texture: These are intentionally soft, dense, and brownie-like rather than light and fluffy. That rich chocolate-banana texture is exactly what makes the three-ingredient recipe work.
