How to Make Them
Start by heating your oven to 425°F. Line a 12-cup muffin pan with paper liners.
In a large bowl, whisk together the all-purpose flour, whole-wheat flour, cocoa powder, baking powder, baking soda and salt. Give everything a quick stir so the cocoa is evenly mixed.
In a separate bowl, mash the bananas. Add the Greek yogurt, nut butter, egg, honey, milk, oil and vanilla. Whisk until the mixture looks smooth.
Pour the wet ingredients into the bowl with the dry ingredients. Gently fold them together until just combined. If you are adding chocolate chips or nuts, fold them in at this point.
Avoid over mixing the batter. When you no longer notice the flour is dry, stop stirring. Muffins can be dense if over mixed.
Divide the batter between the muffin cups, filling them generously.
Bake for 5 minutes at 425°F. Then lower the oven temperature to 350°F and continue baking for about 12 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
Let the muffins cool in the pan for about 5 minutes before moving them to a rack.
Simple Tips for Better Muffins
The bananas make a big difference in this recipe. The riper they are, the more flavorful and naturally sweet your muffins will be.
Don’t worry if the batter looks a little thick. That is normal. Just avoid stirring it too much.
For extra chocolate flavor, mix in dark chocolate chips. If you prefer some crunch, walnuts or pecans are a great addition.
You can also sprinkle a few chocolate chips on top before baking for a bakery-style finish.

How to Store Them
Once the muffins have cooled completely, place them in an airtight container. They can be kept at room temperature for short-term storage.
You can also freeze them if you want to prepare them ahead of time. Wrap the muffins individually and place them in a freezer-safe bag or container. When you want one, let it thaw or warm it gently before serving.
Final Thoughts
These high-protein chocolate banana muffins are an easy way to use ripe bananas while making something that feels like a treat. They are soft, chocolatey and satisfying, with ingredients that come together without much effort.
Make a batch for breakfast, pack one for a snack, or freeze a few for later. Once you try them, those overripe bananas on your counter may never go to waste again.
