These healthy oatmeal protein muffins are made with whole wheat flour, oats, Greek yogurt, protein powder, applesauce, and no added sugar. They’re kid-friendly and perfect for meal prep.
This recipe actually came about because Birch loves to help in the kitchen – especially cracking eggs and stirring batter. One morning we just started tossing together some pantry staples, aiming for something simple, wholesome, and not too sweet…and these healthy oatmeal protein muffins were the result.
They’re soft, lightly sweetened, and made with everyday ingredients you probably already have. They also have boosted protein from yogurt, milk, eggs, and optional vanilla protein powder and are just about as wholesome as you can imagine with applesauce, oats, and whole wheat flour!
They’re perfect for kids’ breakfasts and lunchboxes, and just as good with a cup of coffee for adults.
And did I mention they are hot out of the oven in about 20 minutes flat!? If you’re quick with the mixing!

Healthy Oatmeal Protein Muffins

Ingredient Nutrition
- Whole wheat flour + oats – hearty and filling
- Unsweetened applesauce – adds moisture and gentle sweetness
- Greek yogurt – boosts protein and keeps them tender
- Vanilla protein powder – adds a little staying power
- Cinnamon + vanilla – flavor without extra sugar
Ingredients
- 1 cup whole wheat flour
- 1 cup quick oats
- 1 tsp baking soda
- 1 tsp cinnamon
- ¼ tsp salt
- ¼ cup vanilla protein powder
- 2 eggs
- ½ cup milk (+ 1-2 tbsp more as needed)
- ½ cup unsweetened applesauce (a 4 oz cup)
- ¼ cup plain Greek yogurt
- 2 tbsp oil or melted butter
- 1 tsp vanilla extract
How To Make Oatmeal Protein Muffins
1. Preheat your oven
Preheat to 375°F and line or grease a muffin tin.
2. Mix the dry ingredients
In a large bowl, whisk together: whole wheat flour, oats, baking soda, cinnamon, salt, and protein powder.
3. Mix the wet ingredients
In another bowl, whisk the eggs, milk, applesauce, yogurt, oil or butter, and vanilla.
4. Combine
Pour the wet ingredients into the dry and stir gently until just combined.
The batter will be thick, especially if you let it sit and the oats start to soak up the milk. Add an extra splash of milk if needed until it’s scoopable.
5. Bake
Divide into muffin cups (about ¾ full) and bake for 15 minutes, until set and lightly golden. I LOVE the Caraway muffin tin and don’t have to grease it.
6. Cool
Let cool for a few minutes before transferring to a rack. Cool completely until putting in tupperware or a freezer bag.
Kid-Friendly Notes
These muffins are intentionally simple with no chunks, raisins, or nuts because my kids can’t handle texture. But if you’re baking for adults (or more adventurous eaters), you can absolutely dress them up!
Optional Add-Ins for Grown-Ups
- Chopped walnuts or pecans
- Dark chocolate chips
- Blueberries
- Raisins or chopped dates
- Shredded coconut
- A sprinkle of flax or chia seeds

Muffin Questions
Can I make these without protein powder?
Yes. Replace it with an equal amount of flour.
What kind of protein powder works best?
A vanilla whey works best. I love Ancient Nutrition’s Vanilla Whey. You may need to adjust the milk depending on the brand.
Are these muffins sweet?
They’re lightly sweet and more on the mild side – they almost remind me of the sweetness level of a corn muffin. You can definitely add some sweeteners if you like – maple syrup, honey, or raw sugar work.
Can I make them dairy-free?
Use a non-dairy milk and dairy-free yogurt. You can also just leave out the yogurt and add a splash more milk.
