I published this recipe a few years ago after a classic kitchen crisis. I had three bananas on the counter that were so ripe, they were practically black. I couldn’t bear to toss them, but I also didn’t want plain banana bread. I wanted something that felt like a treat, a real celebration of those sweet, spotty bananas.

That’s when the idea hit me: Double Chocolate Banana Muffins. It was my way of turning a “must-use” ingredient into a decadent breakfast or a perfect afternoon pick-me-up. I love this technique of using what you have to create something new and exciting. It’s how I bake most of the time.
My secret for this recipe is a little extra splash of coffee. You won’t taste the coffee itself, I promise. It just makes the chocolate flavor sing. It’s my favorite little trick for all chocolate baked goods, and it works wonders here.

Why This Recipe is So Special
This recipe is special because it’s a two-for-one. You get the moist, sweet goodness of banana bread. Then you get the rich, deep pleasure of a chocolate muffin.
They come together in one bowl for easy cleanup. The melted butter and mashed banana create an incredibly tender crumb. Adding chocolate chips two ways—in the batter and on top—means every single bite is packed with flavor.
It’s the ultimate solution for overripe bananas. These muffins feel indulgent but have a bit of fruit tucked inside. That’s a win in my book.

The Full Ingredient List
Gathering your ingredients is the first step to baking success. I like to line everything up on my counter before I start. It makes the process so smooth.
- 1 ½ cups all-purpose flour
- ½ cup unsweetened cocoa powder (use a good quality one!)
- 1 teaspoon baking soda
- ½ teaspoon fine sea salt
- 3 medium very ripe bananas (about 1 ½ cups mashed)
- ½ cup unsalted butter, melted and slightly cooled
- ¾ cup packed light brown sugar
- 1 large egg, at room temperature
- 1 teaspoon pure vanilla extract
- 1 tablespoon strong brewed coffee or milk, at room temperature
- 1 cup dark chocolate chips, divided
My Step-by-Step Method
Here’s my simple, no-fuss method. I’ve made these dozens of times, and this order works perfectly every single time. Let’s get baking!
- Preheat your oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or grease it well.
- In a medium bowl, whisk the flour, cocoa powder, baking soda, and salt together. This makes sure the dry ingredients are evenly mixed.
- In a large bowl, mash the ripe bananas with a fork until mostly smooth. A few small lumps are just fine.
- To the mashed bananas, add the melted butter, brown sugar, egg, vanilla, and coffee. Whisk it all together until it’s completely combined.
- Add the dry ingredients to the wet ingredients. Gently fold everything together with a spatula. Stop when you no longer see dry flour. Do not overmix.
- Fold in ¾ cup of the dark chocolate chips. Save the rest for topping the muffins.
- Divide the batter evenly among the 12 muffin cups. They will be quite full, which is what we want for nice, domed tops.
- Sprinkle the remaining ¼ cup of chocolate chips over the tops of the muffins.
- Bake for 20 to 22 minutes. A toothpick inserted into the center should come out with just a few moist crumbs, not wet batter.
- Let the muffins cool in the pan for 5 minutes. Then, move them to a wire rack to cool completely. Try to wait at least 10 minutes before eating one!
My Top Tips for Success
- Banana Ripeness is Key: The blacker the banana peel, the sweeter and more flavorful your muffins will be. This is non-negotiable for the best taste.
- Use Room Temperature Egg & Coffee: This prevents the melted butter from seizing up when you mix it in. It makes for a smoother, more even batter.
- Measure Your Flour Correctly: Spoon the flour into your measuring cup and level it off. Don’t scoop directly from the bag. This packs in too much flour and leads to dry muffins.
- Don’t Skip the Topping Chips: Pressing a few extra chips on top before baking gives you those beautiful, melty pools of chocolate. It makes them look bakery-perfect.
Common Mistakes to Avoid
We’ve all been there. A simple misstep can change the result. Here’s how to avoid the most common ones with this recipe.
Overmixing the Batter: Once you add the flour, mix just until combined. Overmixing develops the gluten and makes muffins tough and dense. A few streaks of flour are okay.
Using Cold Ingredients: Adding a cold egg or milk to melted butter can cause the butter to harden into little bits. This makes your batter look curdled. Always use room temperature wet ingredients.
Overbaking: Set your timer! Check at the 20-minute mark. An overbaked muffin loses its wonderful moisture. Remember, the toothpick test should show moist crumbs, not be completely clean.

FREQUENTLY ASKED QUESTIONS
Can I make these muffins without the coffee?
Absolutely! The coffee just boosts the chocolate flavor. You can replace it with the same amount of milk, buttermilk, or even water. The muffins will still be delicious.
Can I use milk chocolate chips instead of dark?
You can, but the muffins will be much sweeter. I love the balance of sweet banana and rich dark chocolate. If you’re a true milk chocolate lover, go for it!
How should I store these muffins?
Keep them in an airtight container at room temperature for up to 3 days. For longer storage, freeze them in a single layer on a baking sheet, then transfer to a freezer bag. They’ll keep for about 3 months.
