We love a healthy bake, but only if it tastes good, like our healthy chocolate cupcakes and healthy chocolate chip cookies. That’s why we tested this protein blueberry muffins recipe until we found the perfect balance: soft, moist muffins with juicy jammy blueberries, a nice boost of protein, and just the right amount of sweetness.
These are the muffins we make on repeat, like our healthy oat banana muffins — the kind you’ll feel good grabbing for busy mornings, snack cravings, or whenever you need a little lift.
Why they'll be your favourite
Made with healthier ingredients— We skipped the heavy stuff and used oat flour, whole wheat flour, natural sweeteners, and healthy fats — so these high protein blueberry muffins are better for you but still taste amazing, like our healthy chocolate cheesecake bars!
High-protein— Greek yogurt magic, and higher protein flour swaps give these blueberry and yogurt muffins real staying power — they’re not just another sugar crash waiting to happen. No protein powder needed!
Soft, fluffy, and delicious— No weird, dense bites here! These blueberry protein muffins are soft, fluffy, and genuinely delicious. Healthy can (and should!) taste this good.
Ingredients list
Oat flour—Gives the muffins a soft, tender texture and a slightly nutty flavor. Plus, it’s a whole-grain win without feeling heavy.
Whole-wheat flour—For extra fiber and nutrition. It gives more structure to the blueberry protein muffins without making them dry or dense.
Greek yogurt—Our secret weapon for adding protein and keeping the muffins super moist. It also gives a slight tang that balances the sweetness perfectly.
Buttermilk—Helps tenderize the muffins and gives them a beautiful, soft crumb. It also boosts the rise, so your muffins turn out light and fluffy!
Honey—For natural sweetness and extra moisture. Not only does it taste amazing, but it also keeps these healthy blueberry muffins with oats from drying out.
Oil—A little oil makes a big difference! It adds richness and softness, keeping the muffins light instead of rubbery.

Substitutions and variations
Swap the honey—Use maple syrup or agave if that’s what you have — they’ll add a slightly different, delicious flavor.
Add-ins—Stir in some chocolate chips, seeds, or chopped nuts for extra fun, flavor, and even more boost of protein.
Make it dairy-free—Use a plant-based yogurt and milk with a splash of vinegar or lemon juice instead of buttermilk — super easy!

Step-by-step instructions
Dry ingredients
In a large bowl, mix oat flour, whole-wheat flour, and anything else dry— this prevents clumps later.
Blueberries
In a small bowl, coat blueberries with 1-2 tablespoon of dry ingredients— this avoids them sinking to the bottom.
Wet ingredients
In another bowl, whisk together the Greek yogurt, buttermilk, honey, and the rest until smooth.
Combine
Mix the dry ingredients into the wet. Stop when just combined — overmixing makes tough muffins!
Fold in blueberries
Gently fold in the blueberries so they stay whole and juicy.
Rest and scoop
Let the batter sit for 10–15 minutes, giving the flour time to soak up the liquids, making the muffins softer and fluffier. Scoop the batter into a lined muffin tin. Optional: press some blueberries on top!
Bake
Bake at 430°F for 5 minutes, and another 18 minutes at 350°F, until a toothpick inserted comes out clean or with just a few crumbs.
Our best tips
- Don’t overmix the batter. Mix just until you don’t see dry spots. Overmixing makes the blueberry protein muffins dense and rubbery instead of light and fluffy.
- Let the batter rest. A quick 10–15 minute rest lets the flour soak up the liquid, giving you softer, taller muffins.
- Use fresh or frozen blueberries. Both work! If using frozen, don’t thaw them — this keeps your batter from turning purple.
- Check doneness early. Every oven is a little different. Start checking a few minutes before the timer — they are ready when a toothpick comes out clean or with just a few crumbs.
Storage guide
Room temperature
Keep the blueberry protein muffins in an airtight container. They last up to 4 days.
Fridge
Pop them in the fridge to stay fresh for up to 7 days.
Freezer
- Cool the blueberry protein muffins completely, then freeze them in a single layer before tossing them into a freezer bag.
- They’ll keep for up to 3 months.
- To enjoy, just thaw at room temp and give them a few seconds in the microwave for that fresh-baked feel.
Frequently asked questions
You can, but the batter will be a bit thinner. Greek yogurt gives the blueberry protein muffins more protein and a moister texture.
Absolutely! Just add them straight from the freezer — no need to thaw. This keeps your batter from turning purple and runny.
A short rest lets the flour soak up the liquid, making the muffins softer, fluffier, and helping them rise better in the oven.
