- Preheat the oven to 350°F. Lightly grease an 8x8” baking dish with nonstick spray. 
- Blend rolled oats into oat flour using a blender or food processor. Skip this step if using almond flour. 
- In a blender, combine cottage cheese, eggs, syrup, vanilla extract, lemon juice, and protein powder. Blend until smooth. 
- Add the oat flour, cinnamon, baking powder, and salt. Stir until just combined. 
- Gently fold in the blueberries. 
- Pour the mixture into the prepared baking dish and smooth out the top. 
- Bake for 35–40 minutes, or until the center is set and the top is lightly golden. The bake should begin to pull away from the sides. 
- Let cool slightly before slicing into 4 servings. Enjoy warm or cold. Optional: sprinkle with powdered monk fruit or drizzle with syrup.
