I love these Peanut Butter Banana Muffins and they became a total breakfast win in my house. I wanted to make a muffin with a serious protein boost that was still full of flavor, moist, and tender. This recipe is just that, the muffins are so soft and fluffy, and you'd never even guess they're a "better-for-you" version of the classic.
I'm all about turning basic pantry staples into something that actually keeps me full until lunch. These muffins have all the flavor of a thick slice of warm banana bread, but that nutty peanut butter twist makes them much more substantial. They are the perfect grab and go for those busy mornings!

Why You'll Love Peanut Butter Banana Muffins
High protein: I used PB Fit powder and ultra-filtered milk to get these up to 9 grams of protein per muffin. It's the perfect way to justify having a muffin (or two) for breakfast!
The best flavor combo: you really can't go wrong with peanut butter, banana, and chocolate. It's sweet, but not "dessert-level" sweet, so you don't feel sluggish afterward.
Great texture: the mashed bananas keep these so tender. Even with the extra protein, they don't get dry or crumbly like some "fit" recipes do.
Key Ingredients for High Protein Muffins
See the recipe card below for a full list of ingredients and instructions:
- Ripe bananas: these add natural sweetness and help keep the muffins soft and tender.
- PB Fit Powder (affiliate link): peanut butter powder gives strong peanut butter flavor while blending smoothly into the batter.
- Ultra-filtered milk: I love using ultra-filtered milk here because it has 50% more protein and half the sugar of regular milk. My preferred brand is Fairlife 2% Milk.
- Chocolate chips: I like to use semi-sweet chips chips here.
- Brown sugar: adds a deeper sweetness that pairs nicely with banana and peanut butter.
- Cinnamon: a small amount brings warmth to the flavor without overpowering the other ingredients.
Ingredient Substitutions
- Milk swap: regular whole milk can replace the ultra-filtered milk, though the protein content of the muffins will be lower.
- Sugar option: use all light brown sugar instead.
- Chocolate choice: use dark chocolate chips or mini chips.
Variations on Peanut Butter Banana Muffins
Double Chocolate: swap ½ cup of flour for cocoa powder and an extra splash of ultra filtered milk to keep them moist. It's basically a high-protein peanut butter cup in muffin form!
The Crunchy Power-up: trade the chocolate chips for ½ cup of chopped walnuts or pecans.
PB&J Twist: skip the chocolate chips and drop a teaspoon of strawberry or grape jam into the center of the batter before baking. It's a fun nostalgic version that always disappears fast in my house.
Tips for the Best High Protein Muffins
- Don't overmix the batter: once you add the wet ingredients to the dry, stir just until you don't see any more streaks of flour. If you overwork the batter, the muffins can turn out tough and dense instead of soft and fluffy.
- Use ripe bananas: bananas with brown spots mash easily and provide better sweetness and moisture.
- Check for doneness early: since every oven runs a little differently, start checking your muffins at the 18-minute mark. Stick a toothpick in the center; if it comes out clean or with just a few moist crumbs, they're ready to come out!
How to Store
- On the counter: keep in an airtight container for 3 days. Line the bottom with a paper towel to keep them from getting sticky.
- In the fridge: they'll stay fresh for 5-6 days. Just zap one in the microwave for 10 seconds to soften it back up.
- In the freezer: wrap them individually and freeze for up to 3 months. Thaw on the counter or defrost in the microwave for a quick breakfast.
Serve With...
Pair these muffins with Crockpot Boiled Eggs or Homemade Chicken Breakfast Sausage for a quick, high-protein breakfast. If you want something lighter, a side of Fruit Salad with Lime Ginger Dressing adds a nice refreshing zip.
