Banana Protein Muffins You Make in One Blender

These banana protein muffins come together in one blender: oats go in first and turn into flour, then the bananas, eggs and Greek yogurt follow, and a scoop of whey goes in last. Each muffin has about 150 calories and 8.5 g of protein, so two of them with coffee make a 17 g protein breakfast you can grab on the way out the door.

The trick is restraint with the powder. Too much whey is what makes most protein muffins dry and rubbery, so this batch uses just two scoops and lets the yogurt and eggs carry the rest.

Banana Protein Muffins Recipe (12 Muffins)

Prep: 10 minutes, plus a 10-minute rest. Bake: 18 to 22 minutes. Makes: 12 standard muffins.

Ingredients

• 2 cups (160 g) old-fashioned rolled oats
• 3 medium very ripe bananas (330 g peeled, about 1 1/2 cups mashed)
• 2 large eggs
• 3/4 cup (170 g) plain nonfat Greek yogurt
• 1/4 cup (80 g) maple syrup
• 2 tablespoons (27 g) olive oil or another mild oil
• 1 teaspoon vanilla extract
• 2 scoops (60 g) vanilla whey protein powder
• 1 teaspoon baking powder
• 1/2 teaspoon baking soda
• 1 teaspoon cinnamon
• 1/4 teaspoon salt
• Optional: 1/3 cup dark chocolate chips, chopped walnuts or blueberries

Instructions

1. Heat the oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or grease it well.
2. Blend the oats on high for 30 to 45 seconds, until they look like fine flour.
3. Add the bananas, eggs, Greek yogurt, maple syrup, oil and vanilla. Blend until completely smooth, about 30 seconds.
4. Add the protein powder, baking powder, baking soda, cinnamon and salt. Pulse 5 or 6 times, just until no dry powder is visible. Let the batter rest for 10 minutes so the oat flour can soak up liquid and thicken.
5. Stir in any add-ins by hand with a spatula, then divide the batter among the cups. They will be about three-quarters full.
6. Bake for 18 to 22 minutes, until the tops spring back when pressed and a toothpick in the center comes out clean. Cool in the pan for 10 minutes, then move the muffins to a rack.

Per muffin (without add-ins): about 150 calories, 8.5 g protein, 21 g carbs, 2 g fiber and 4 g fat. I calculated this from USDA FoodData Central values (sources at the end).

How Much Protein Is in Each Muffin?

The whey does the heavy lifting, but it supplies less than half of the batch. Oats, yogurt and eggs add almost 52 grams between them, which is why you don’t need a third scoop.

Ingredient	Amount	Protein (whole batch)	Calories (whole batch)
Whey protein powder	60 g (2 scoops)	46.9 g	211
Rolled oats	160 g (2 cups)	21.1 g	606
Nonfat Greek yogurt	170 g (3/4 cup)	17.5 g	104
Eggs	2 large (100 g)	12.6 g	143
Bananas	330 g (3 medium)	3.6 g	294
Maple syrup + oil	80 g + 27 g	0 g	447
Total / per muffin	12 muffins	101.7 g / 8.5 g	1,805 / 150

The powder row uses USDA’s generic whey-based protein powder entry (78.1 g protein per 100 g). Your tub may be a little higher or lower, so check its label. A scoop with 20 g of protein instead of 23 g still leaves you at roughly 8 g per muffin.

Tips for Moist Protein Muffins (Not Rubbery Ones)

• Use spotty bananas. The browner the peel, the sweeter and softer the fruit. Yellow bananas with green tips make bland, dense muffins and you’ll want more syrup.
• Keep the powder at two scoops. Whey sets firm when it bakes, so every extra spoonful makes the crumb springier and drier. If you want more protein, add a bit more Greek yogurt, not more powder.
• Pulse, don’t blend, after the powder goes in. Long blending at this stage beats air out and toughens the batter.
• Don’t skip the rest. Ten minutes lets the oat flour hydrate, so the muffins dome instead of spreading flat.
• Pull them early. Protein muffins dry out fast in the last couple of minutes. Start checking at 18 minutes.

Which protein powder works best?

Whey or a whey-casein blend gives the softest crumb. Plant proteins (pea, soy, rice blends) work, but they drink more liquid: add 2 to 3 tablespoons of milk to the batter and expect a slightly denser, earthier muffin. Collagen doesn’t bind like whey, so I don’t use it here. Vanilla or unflavored keeps the banana front and center; chocolate powder turns these into something close to a brownie muffin.

Banana Protein Muffin Variations

Each one starts from the base batter. Fold mix-ins in by hand after the rest, so they don’t get chopped up in the blender.

• Chocolate chip banana: fold in 1/3 cup dark chocolate chips and sprinkle a few more on top before baking. This is the one kids ask for.
• Blueberry banana: fold in 1/3 cup fresh or frozen blueberries. If frozen, don’t thaw them first, and add 2 minutes to the bake time.
• Banana nut: fold in 1/3 cup chopped walnuts or pecans for crunch.
• Peanut butter banana: swap the oil for 2 tablespoons of smooth peanut butter and blend it in with the wet ingredients.
• Chocolate banana: use chocolate protein powder and add 2 tablespoons of unsweetened cocoa with the dry ingredients.

Add-ins change the numbers above, so treat 150 calories and 8.5 g as the plain-muffin baseline.

Banana protein muffins without protein powder

Replace the two scoops with an extra 1/2 cup (40 g) of oats. The muffins come out softer and more like classic banana bread, at about 145 calories and 5 g of protein each. Pair two of them with a glass of milk or a yogurt cup to make up the difference.

How to Store and Freeze Protein Muffins

FoodSafety.gov’s cold storage chart doesn’t list muffins by name. Because these carry eggs and Greek yogurt, I treat them like the baked egg dishes on that chart: refrigerate them in an airtight container at 40°F (4°C) or below and eat them within 3 to 4 days, the window it gives for casseroles with eggs after baking.

For longer storage, freeze them. Cool the muffins completely, wrap each one or pack them in a freezer bag, and use them within 2 to 3 months for the best texture (the chart’s quality guidance for baked egg casseroles). To eat, microwave a frozen muffin for 30 to 40 seconds, or move it to the fridge the night before.

They fit neatly into a Sunday prep session. Bake a batch alongside our cottage cheese egg bake and you have savory and sweet breakfasts sorted for the week. For more make-ahead ideas, see our high protein breakfast meal prep plan.

FAQ

Are banana protein muffins healthy?

These are a reasonable everyday breakfast or snack: whole-grain oats, fruit, a modest 1/4 cup of maple syrup for 12 muffins, and about 8.5 g of protein each. For a fall version, try our healthy pumpkin muffins or, for something portable, our homemade granola bars.

Can I use regular flour instead of oats?

Yes. Swap the 2 cups of blended oats for about 1 1/2 cups of all-purpose or white whole wheat flour and mix the batter in a bowl instead of the blender. Skip the 10-minute rest, since wheat flour doesn’t need it. The muffins will be lighter and a little less filling.

Can I make them in a mini muffin pan?

Yes. The batter makes about 36 mini muffins. Bake them for 10 to 12 minutes and check early. Three minis equal roughly one standard muffin.

If you’d rather skip the oven entirely, the banana peanut butter jar in our protein overnight oats recipe uses the same banana-and-whey combo with no baking at all.
