Hot Tip: Baking at a higher temperature for the first five minutes will help them rise tall for picture-perfect chocolate muffins.

Swaps: For a guilt-free treat, use whole wheat flour as a healthier alternative to all-purpose flour in this muffin recipe.

Ingredient Notes for Easy Double Chocolate Banana Muffins

  • Bananas | Over-ripe bananas are perfect for this recipe as they’re sweeter and easier to mash.
  • Vanilla | Vanilla adds a warm, aromatic boost that melds the chocolate and banana flavors.
  • Egg | The egg acts as a binder, holding the ingredients together and providing structure for a tender crumb.
  • Oil | Canola oil helps keep the muffins moist and tender without altering the flavor.
  • Milk | 2% milk adds moisture and creates a soft, light texture.
  • Sugars (granulated & brown) | Granulated sugar sweetens, while light brown sugar adds a hint of molasses for depth.
  • Cocoa | Unsweetened cocoa powder provides the signature chocolate flavor, making these muffins rich and indulgent.
  • Salt | Enhances overall flavors and balances the sweetness.
  • Baking soda | Leavens the muffins, making them fluffy and light.
  • Flour | All-purpose flour provides structure and texture to the muffins.
  • Chocolate chips | Semi-sweet chips melt into gooey pockets of chocolate, enhancing the double chocolate experience.

Variations and Substitutions

  • Healthier Chocolate Banana Muffins. To make a healthier version of this yummy muffin recipe, swap the sugar with honey, use whole wheat flour, and trade canola oil for coconut oil. 
  • Oil Substitutions. Other oils, such as avocado, coconut, or olive oil, will work for this recipe. Melted butter will also do the trick if preferred.
  • Add-Ins. Add to the chocolate chips or substitute with nuts or dried fruit

Just one bowl and simple ingredients, and in under 30 minutes, you have chocolatey banana muffins!

REDUCE TEMP AND CONTINUE BAKING. Then, reduce the oven temperature to 375 degrees (without opening the oven door) and continue baking for another 8 to 10 minutes, or until a pick inserted into the center of the muffins comes out clean.

COOL AND ENJOY. After removing the freshly baked muffins from the oven, let them cool in the tin for 5 minutes before moving them to a wire rack to cool completely. Finally, dig in! These muffins are best enjoyed warm or at room temperature.

More Recipe Success Tips

Resist the urge to stir and stir the muffin batter. Too much stirring causes the muffin texture to become a little drier and tougher.

Use paper cupcake liners coated lightly with cooking spray in the muffin tins for easy removal from the pan.

Spoon the muffin batter into the pans immediately after mixing it together, and get them into the oven quickly. This will result in a better rise.

Storage Tips

  • These muffins will stay moist for 3-4 days when stored in a ziplock bag or sealed container, but you won’t have to worry about that because they’re guaranteed to disappear quickly!
  • You can also freeze your leftover muffins by placing them in a freezer bag. They will freeze well for up to three months. Set them out at room temperature to enjoy later when completely thawed.

Frequently Asked Questions

Why are my muffins flat?

You might have overmixed the batter or not used enough leavening agent. Make sure to gently fold in the dry ingredients and check your baking soda for freshness!

How do you get tall muffin tops?

Start baking at a higher temperature (425°F) for the first 5 minutes to give them a good rise, then reduce the heat to finish baking.

What is the secret to moist muffins?

The secret to moist muffins is using ingredients like ripe bananas, oil, and milk. They help keep the batter soft and tender. Also, avoid overmixing the batter, as that can make them dry!

How do I ripen bananas quickly?

You can ripen bananas quickly by placing them in a paper bag with an apple or avocado—those release ethylene gas, which speeds up the process. If you’re really in a rush, you can also pop them in the oven at 300 degrees F. for about 15-20 minutes until they’re soft and brown!
