I set out to make bakery-style banana muffins that happen to pack 9g protein each, and these are exactly that! Thanks to Greek yogurt, hemp seeds, eggs and collagen, they remind me of the soft banana muffins I grew up on, but with a serious protein punch. These beauties are impossibly moist (with no oil!), just lightly sweetened, and made with nourishing almond and oat flour. Ready in under 30 minutes and a slam dunk with the kids!

Finally, a high protein muffin that *actually* tastes like a muffin! You better believe we're not prioritizing macros over texture here.
We can all make a "protein muffin" by tossing a scoop of protein into your fave healthy banana muffins and calling it a day. But you know that's not how we roll!
The dietitian in me wanted these to pack a protein punch primarily from whole food ingredients. That's why I developed this recipe intentionally with Greek yogurt, eggs, hemp seeds, and almond + oat flour.
Even without the collagen, these muffins still boast 7g protein each. Bliss!
What sets these gems apart from the rest
- They have a legit bakery-style texture and flavor without all purpose flour. Love at first bite! (Did I mention they're gluten free?)
- They're kid approved first, protein muffin second. The fact that Charlie and Max gobbled these up seals the deal even more than the macros.
- They're lower in sugar than even most healthy muffins. Score!

Tidbits from testing
I thought developing this recipe would be a couple simple tweaks to my beloved Greek yogurt chocolate chip muffins, but boy was I wrong. I ended up with a completely different recipe.
Since we're relying on banana and Greek yogurt for moisture plus the healthy fats from the almond flour, I was surprised to find these didn't need any olive oil at all.
You'll also notice there's no milk in this batter, and that's by design. I opted for coconut sugar instead of my usual maple syrup to keep the batter nice and thick. I've learned when you're baking with almond and oat flour, thicker batter is often the key to fluffy, taller muffs.
Let's bake!






Why collagen is the bomb here
Collagen is what I like to call protein unicorn. I love baking with it because it boosts the protein without altering the texture (ahem, making it chalky) like many proteins powders do. It also has no flavor, so you won't even notice it's there.
That said, collagen isn't a complete protein since it lacks leucine, a key amino acid for building muscle. That's why I paired it with Greek yogurt, eggs, and hemp seeds in this recipe!
I tested this recipe with plant protein, and it made the batter too dry. I recommend sticking with collagen or simply leaving it out rather than substituting another protein powder.

Description
I set out to make bakery-style banana muffins that happen to pack 9g protein each, and these are exactly that! Thanks to Greek yogurt, hemp seeds, eggs and collagen, they remind me of the soft, fluffy banana muffins I grew up on, just with a protein punch. These beauties are impossibly moist (with no oil!), lightly sweetened, and made with nourishing almond and oat flour. Ready in under 30 minutes and a slam dunk with the kids!
Baking in Denver at altitude, my muffins always turn out a bit flatter. Yours will be taller!
Ingredients
- 1 ½ cups oat flour
- 1 cup almond flour
- ⅓ cup coconut sugar (use ½ cup for sweeter muffins)
- 1 tsp baking powder
- ½ tsp baking soda
- ½ tsp cinnamon
- ¼ tsp fine sea salt
- ¼ cup hemp seeds*
- ⅓ cup collagen peptides, optional**
- 1 cup very overripe mashed bananas
- ¾ cup plain Greek yogurt (I use FAGE 0%)
- 3 large eggs
- 2 tsp pure vanilla extract
- ⅓ cup semi sweet or chocolate chips/chunks, plus more for topping (optional)
Instructions
- Preheat oven to 350F. Spray a muffin tin very well with oil sprayer or use paper liners (these came out of the muffin tin well for me using just oil).
- Place oat flour, almond flour, coconut sugar, baking powder, baking soda, cinnamon, salt, hemp seeds and collagen in a large mixing bowl. Whisk to combine.
- Mash banana in a medium mixing bowl. Measure to ensure you have a cup, then add yogurt, eggs and vanilla. Whisk until smooth. Pour wet into dry and stir with a wooden spoon until just combined (you should still see of streaks of flour. It will be thick! Fold in chocolate chips if using.
- Use a muffin scoop or ¼ measuring cup to portion batter into oiled muffin tin.
- Bake for about 18 minutes. Let muffins cool for 15 minutes then use a knife to carefully remove muffins from tin. Enjoy! Store in an air-tight container on the counter for up to 2 days then refrigerate.
Notes
*Hemp seeds and collagen are included for extra protein but can easily be omitted or reduced and the flavor and texture of these won't be impacted.
**I don't recommend any other protein powder here--collagen works since it's undetectable whereas plant and whey protein can really alter the texture and make these too dry!
