Let's be real for a second. Most "healthy" muffins promise a lot and then deliver something dry, bland, and kind of sad. These low calorie high protein banana muffins are not that.
You're basically taking ripe bananas, a touch of natural sweetness, and protein powder and turning them into soft, fluffy muffins that feel like something you'd grab from a bakery, not a diet food aisle. They are sweet enough to feel satisfying, sturdy enough to keep you full, and easy enough that you can whip them up on a busy weekday.
If you've been trying to increase your protein without eating the same boring snacks over and over, this recipe is about to become your go-to. They work for breakfast, after workouts, lunchboxes, or those late evening moments when you want something sweet but still balanced.
And the best part? They come together in one bowl and are ready in under 30 minutes.
Ingredients That Make the Difference
Banana Puree
This is not the place for barely yellow bananas. You want them spotty, soft, and very ripe. Blending them into a smooth puree instead of mashing is key. It distributes moisture evenly and gives the muffins a much better crumb.
Almond Flour and Oat Flour
Using a mix of almond flour and oat flour gives you the best texture. Almond flour keeps things moist and tender, while oat flour adds structure so the muffins hold together. You can use all of one if needed, but the combination really shines here.
Protein Powder
A vanilla protein powder works best. Pea protein and whey protein both work, but make sure it is lightly sweetened. Unsweetened protein powder can make baked goods taste flat unless you compensate with more sweetener.
The amount used here boosts protein without turning the muffins dense or chalky.
Eggs
Eggs help bind everything together and add extra protein. They also help the muffins rise properly, which is especially important when baking with protein powder.
Honey
Honey adds just enough sweetness to balance the bananas and protein powder. The muffins are not overly sweet, which makes them great for everyday snacking.
Optional Add Ins
Chocolate chips or chopped walnuts are completely optional, but highly recommended if you want that bakery-style feel. A small amount goes a long way.
How to Make Low Calorie High Protein Banana Muffins
Step 1: Prep Your Oven and Pan
Preheat your oven to 350 degrees Fahrenheit. Line a muffin tin with liners and lightly spray them. Protein powder tends to stick, so this step really matters.
Step 2: Mix the Wet Ingredients

In a large bowl, whisk together the banana puree, eggs, honey, and vanilla extract until smooth and fully combined.
Step 3: Add the Dry Ingredients

Add the almond flour, oat flour, protein powder, baking powder, cinnamon, and salt. Whisk until you have a smooth, thick batter. Try not to overmix.
Step 4: Fold In Extras

If using chocolate chips or nuts, gently fold them in at the end.
Step 5: Bake

Divide the batter evenly between the muffin liners, filling each about three quarters full. Bake for 18 to 24 minutes, until a toothpick inserted in the center comes out clean.
Let the muffins cool completely before removing them from the pan. This helps them set and improves the texture.

Storage and Meal Prep Tips
These low calorie high protein banana muffins are perfect for meal prep.
Room Temperature
Store them in an airtight container for up to five days. They stay moist and soft, especially if you let them cool fully before storing.
Freezer Friendly
Once cooled, place the muffins in a freezer-safe bag and freeze for up to one month. This is great if you like having a quick grab-and-go snack ready.
Reheating
For frozen muffins, thaw in the fridge overnight and warm gently in the microwave or oven. If stored at room temperature, a quick warm-up brings them back to life.
Frequently Asked Questions
Are these muffins really low calorie?
Yes. Each muffin is around 130 calories while still delivering about 10 grams of protein, making them very filling for the calorie count.
Can I use all oat flour instead of almond flour?
Yes. The texture will be slightly more dense, but they will still work and taste great.
What protein powder works best?
Vanilla pea protein or vanilla whey protein with light sweetening works best. Unsweetened protein powder may need extra honey or vanilla.
Can I skip the chocolate chips?
Absolutely. The muffins are delicious on their own, but the chocolate chips add a bakery-style touch.

Jennifer Donoho says
Can Greek yogurt be used in these to cut back the protein powder ?
Betsy says
Yes, you can 😊Swap about ¼–⅓ of the protein powder with Greek yogurt. The muffins will be a bit more moist and slightly denser, and a little lower in protein.
I wouldn’t replace all the protein powder for best texture!
