Ingredients
Make sure you have these on hand:
- 2 ½ cups rolled oats
- ⅔ cup granulated sweetener*
- ⅓ cup protein powder of choice
- 2 tsp baking powder
- ½ tsp sea salt
- 2 large eggs
- 5 ounces plain Greek yogurt**
- 1/2 cup egg whites

Equipment and tips
- 9×5-inch loaf pan (or similar). Line with parchment for easy removal.
- Large mixing bowl, whisk, rubber spatula, measuring cups, and spoons.
- A blender or food processor will give the oats a finer texture if you prefer a less rustic crumb.
- Room-temperature eggs and yogurt help the batter come together evenly.
Step-by-step instructions

The following directions have been rewritten for clarity and flow, following the ingredient list and preserving all quantities. Read through once, then preheat the oven and mix your batter.
- Preheat your oven to 350°F (175°C). Lightly grease a 9×5-inch loaf pan and line it with parchment, allowing a little overhang for easy lifting.
- Measure 2 ½ cups rolled oats into a large mixing bowl. If you prefer a finer texture, pulse the oats in a food processor or blender for 10–20 seconds before adding them to the bowl.
- Add ⅔ cup granulated sweetener, ⅓ cup protein powder of choice, 2 tsp baking powder, and ½ tsp sea salt to the oats. Whisk or stir these dry ingredients together until evenly combined.
- In a separate medium bowl, whisk 2 large eggs until just combined. Stir in 5 ounces plain Greek yogurt, 1/2 cup egg whites, ⅓ cup avocado oil, and 2 tsp pure vanilla extract. Mix until smooth and uniform.
- Pour the wet mixture into the bowl with the dry ingredients. Use a rubber spatula to fold everything together gently until mostly combined; avoid overmixing. The batter will be thick and slightly coarse from the oats.
- Fold in the zest of 1 lemon, distributing it evenly through the batter so each slice will have bright citrus notes.
- Toss 3 cups fresh blueberries with a small pinch of the reserved flour-protein mixture (or a teaspoon of flour). This simple step helps prevent the berries from sinking. Gently fold the blueberries into the batter, taking care not to crush them.
- Spoon the batter into the prepared loaf pan, smoothing the top with the spatula. If you like, scatter a few extra blueberries on top for a pretty finish.
- Bake in the preheated oven for 45–55 minutes, or until the top is golden and a toothpick inserted into the center comes out with a few moist crumbs but no wet batter. If the top is browning too quickly, tent with foil for the last 10–15 minutes of baking.
- Remove the pan from the oven and let the loaf cool in the pan for 10–15 minutes. Use the parchment overhang to lift the bread onto a wire rack and cool completely before slicing. If you slice too early, the interior may be tender and slightly crumbly; letting it cool yields cleaner slices.
Serving suggestions

This Blueberry Protein Bread is delicious served a handful of ways. Enjoy a warm slice with a smear of butter or a drizzle of honey. For a more filling option, top with nut butter and banana slices, or toast slices and spread a thin layer of cream cheese. It also makes a handy snack for on-the-go mornings — wrap slices individually and freeze for quick reheating.
Storage and freezing
Store cooled slices in an airtight container in the refrigerator for up to 5 days. To freeze, wrap individual slices tightly in plastic wrap or parchment, then place them in a freezer-safe bag for up to 3 months. Thaw at room temperature or warm briefly in the toaster or microwave.
Variations and swaps
- Protein powder: Use whey, casein, pea, soy, or any favorite protein powder. The flavor will affect the final loaf slightly, so neutral or vanilla varieties work best.
- Sweetener: Swap the granulated sweetener for coconut sugar or a monk fruit blend for a different flavor profile. If using a sugar substitute, check the package for cup-to-cup substitution guidance.
- Fruit: Try frozen blueberries (do not thaw) or substitute raspberries or chopped strawberries. For a citrus twist, add a tablespoon of fresh lemon juice along with the zest.
- Texture: For a more cake-like crumb, pulse half of the oats into a finer flour before mixing.
Why this recipe works
The balance of oats and protein powder creates structure without the need for large amounts of wheat flour. Greek yogurt and egg whites keep the crumb moist while adding protein and tenderness. Avocado oil provides a neutral, healthy fat that preserves moisture without weighing the bread down. Fresh blueberries contribute juicy pockets that contrast the denser oat texture, and lemon zest brightens the flavor so each bite feels fresh and lively.
Common questions
Can I use rolled oats or quick oats? The recipe calls for rolled oats. If you use quick oats, the texture will be softer and the batter may be a bit looser; it should still work, but keep an eye on bake time.
Can I make this nut-free? Yes — the base recipe is naturally nut-free unless you top it with nut butter. Double-check your protein powder and yogurt labels if you need to avoid cross-contamination.
How do I stop blueberries from sinking? Tossing the berries with a tablespoon of flour or a small amount of the dry mix helps suspend them in the batter.

Blueberry Protein Bread
Ingredients
Equipment
Method
- Preheat the oven to 350°F (175°C). Line a 9 x 5-inch loaf pan with parchment paper and set aside.
- Place the rolled oats in a high-powered blender or food processor and blend 20–30 seconds on low until they become a fine flour.
- Add the granulated sweetener, protein powder, baking powder, and sea salt to the oat flour and pulse briefly until combined.
- In a large bowl, whisk together the eggs, Greek yogurt, egg whites, avocado oil, and vanilla until smooth and well combined.
- Pour the dry mixture into the wet ingredients and stir until a smooth batter forms. Gently fold in the fresh blueberries and lemon zest.
- Transfer the batter to the prepared loaf pan and smooth the top. If desired, sprinkle seeds or nuts on top.
- Bake on the center rack for 50–70 minutes. If using foil, cover the loaf for the first 30 minutes then remove foil and continue baking until done.
- Check doneness by inserting a digital thermometer into the center; the bread is done at 190–205°F (88–96°C). Remove from oven and cool to room temperature before slicing.
Notes
- Use your favorite granulated sweetener (cane, coconut, maple, or sugar-free).
- I prefer 2% or 5% milkfat Greek yogurt but nonfat works too.
- Covering the loaf with foil for the first 30 minutes prevents the top from over-browning.
- Let the bread cool fully before slicing for cleaner slices.
