Ingredients
- 2 cups old-fashioned rolled oats
- 2 scoops vanilla protein powder, approximately 60 grams
- 1 teaspoon baking powder
- 1 teaspoon ground cinnamon
- ¼ teaspoon salt
- 2 large eggs
- 1 cup plain nonfat or low-fat Greek yogurt
- 1½ cups milk of choice
- 2 tablespoons pure maple syrup or honey
- 1 teaspoon vanilla extract
- 1½ cups fresh or frozen blueberries, divided
- Nonstick cooking spray
Optional Toppings
- Additional Greek yogurt
- Fresh blueberries
- Chopped walnuts or almonds
- A small drizzle of maple syrup
- Extra cinnamon
Instructions
- Heat the oven: Preheat the oven to 350°F. Lightly coat an 8-by-8-inch baking dish with nonstick cooking spray.
- Combine the dry ingredients: In a large bowl, stir together the rolled oats, protein powder, baking powder, cinnamon and salt. Break apart any protein-powder clumps.
- Mix the wet ingredients: In a separate bowl, whisk the eggs, Greek yogurt, milk, maple syrup and vanilla until smooth.
- Build the batter: Pour the wet mixture into the dry ingredients and stir until evenly combined.
- Add the blueberries: Gently fold in 1 cup of blueberries. Pour the mixture into the prepared dish and scatter the remaining ½ cup over the top. Frozen blueberries can be added without thawing.
- Bake: Bake for 35–42 minutes, until the center is set and the edges are lightly golden. The center should reach 160°F because the recipe contains eggs.
- Cool: Rest for at least 15 minutes before slicing so the oatmeal can firm up.
- Portion: Divide evenly among four meal-prep containers. Store toppings separately and add them after reheating.
- Refrigerate promptly: Cover and refrigerate within two hours.

Easy Variations

- Add lemon zest for a brighter blueberry flavor.
- Stir in chia seeds or ground flaxseed; add a little extra milk if the mixture becomes too thick.

- Reduce or omit the maple syrup if your protein powder is already sweet.
Recipe Tips
- Use rolled oats rather than quick oats for a firmer, more defined texture.
- Different protein powders absorb liquid differently. Add 2–4 tablespoons of milk if the batter appears unusually dry.
- Do not overbake; the center will continue firming as it cools.
- Frozen blueberries may tint the oatmeal purple, but they work well without thawing.
- Allow the baked oatmeal to cool before cutting clean portions.
Frequently Asked Questions
Can I use frozen blueberries?
Yes. Fold them into the batter directly from the freezer. The oatmeal may need a few additional minutes in the oven and the berries may release more purple color.
Which protein powder works best?
Vanilla whey, whey-casein blends and many plant-based powders can work. Because absorption and sweetness vary, adjust the milk and sweetener as needed.
Can I prepare the batter overnight?
You can refrigerate the mixed batter overnight, but the oats will absorb liquid and create a softer texture. Add a small splash of milk before baking if it becomes very thick.
Can I eat baked oatmeal cold?
Yes. Once properly baked, cooled and refrigerated, it can be eaten cold or reheated according to your preference.
