Preheat oven to 375 degrees F. Line muffin tin with muffin liners and spray with cooking spray. Set aside.
In a large mixing bowl, add an egg, cottage cheese, maple syrup, milk, oil, vanilla extract, cinnamon, baking powder and baking soda. Whisk well until no white lumps of baking powder are visible.
Add flour and gently mix just until combined.
In a small bowl, add blueberries, sprinkle with 1 tablespoon of flour and toss to coat evenly. Add to the bowl with muffin batter and give a few stirs to incorporate.
Divide batter evenly between 12 openings of previously prepared muffin tin. Bake muffins for 23-25 minutes or until toothpick inserted in the center comes out clean.
Remove from the oven, let cool for 15 minutes and enjoy!
