Blueberry muffins will always have my heart, but this baked oats version is what I make when I want something that feels like a sweet treat while still being nourishing and filling. It tastes like dessert, but it’s made with real, wholesome ingredients that keep you satisfied and energized. Between the oats, protein powder, chia seeds, and blueberries, it’s packed with fiber, antioxidants, and protein, making it perfect for breakfast, a pre-workout snack, or even an afternoon pick-me-up. It’s also incredibly easy for meal prep. You bake one dish, slice it up, and you have breakfast ready for days. No morning decisions, no extra cooking, and no mess since everything gets mixed right in the same dish you bake it in.
And if you loved my Banana Bread Baked Oats, this is the blueberry muffin will be a favorite too! Same cozy base, in an equally delicious flavor.

Ingredients
makes 4-6 servings
1½ cups gluten-free rolled oats
½ cup mashed banana
2 tbsp chia seeds
½ cup vanilla protein powder (I used this one)
1¾ cups unsweetened almond milk
1 egg
1 tsp baking powder
1 tsp vanilla extract
¼ tsp salt
1 cup fresh blueberries
For the swirl on top: 2 tbsp almond butter + ½ cup frozen blueberries (or you can use fresh)
Optional: a sprinkle of powdered sugar
Instructions
- Preheat oven to 350°F. Spray your baking dish with avocado oil spray (an 8″ x 8″ pan or 9” x 6” or any similar oven-safe Tupperware works great. I use this one.)
- Crack the egg into the baking dish and whisk. Then add the almond milk and mix well. Add the vanilla extract and mashed banana. Whisk everything together.
- Add the oats, chia seeds, protein powder, baking powder, and salt. Stir until fully combined and no clumps remain.
- Fold in the cup of fresh blueberries, giving everything one last mix.
- Drizzle the almond butter evenly over the batter.
- For the blueberry topping, if you’re wanting that pretty blueberry swirl, add ½ cup frozen blueberries to a microwave-safe bowl. Microwave for 30 seconds, stir, then microwave another 15 seconds until they’re juicy and slightly broken down. (You can also do this on the stovetop over low heat. The goal is saucy, jammy berries.) Note: You can skip this step and just add more fresh blueberries on top.
- Spoon the juicy blueberries over the almond butter. Use a knife to gently swirl everything together to create a marbled effect.
- Bake about 40 minutes or so, until the center is set.
- If the top starts browning before the middle is done, loosely tent with foil and continue baking.
- Remove from the oven and let cool for about 5 minutes. Sprinkle with powdered sugar, then slice into 4-6 servings. Enjoy!
