Preheat the oven to 350 degrees F. Line a muffin tin with liners or grease.
Blend the cottage cheese using a handheld immersion blender, food processor or blender until smooth.
Combine the dry ingredients: Whisk the oat flour, whey protein, almond flour, baking powder, baking soda, cinnamon and salt in a large bowl.
Mix the wet ingredients: In a separate bowl, whisk the banana, blended cottage cheese, greek yogurt, eggs, maple syrup and vanilla extract until smooth.
Combine the wet and dry ingredients in one bowl. Avoid over mixing.
Fold in the blueberries. Save a few for topping.
Fill each muffin tin about 3/4 of the way full. Top with a couple extra blueberries per muffin.
Bake for 22-25 minutes or until a toothpick comes out clean and the top looks lightly golden.
Cool for 5 minutes before transferring to a wire rack.
Store in the fridge for up to 5 days or in the freezer for up to 3 months.
Notes
Pre-blending the cottage cheese helps prevent clumps in the muffins. It also makes it more fluffy, so you won't want to skip this step!
If on a fat loss journey, make sure to pair these muffins with a high protein meal. As a Nutritionist, I find sticking to meals without snacks provides the best fat loss results.
