Blueberry High Protein Muffins (gluten free) Print 4 LikeDislike By Lillian Zhao I’ve made over 20 variations of these gluten free blueberry protein muffins and this perfected recipe is a knock-out every time! These Blueberry Protein Muffins with collagen protein are the perfect choice for a sweet, fluffy and deliciously light snack. Enjoy it in the mornings for a refreshing breakfast, or afternoons for that heart-warming snack, and you’ll want to make another batch right away. Our added collagen protein is key to making it a healthy alternative to those sugar-loaded breakfast muffins–it’ll keep you full longer while also aiding in digestive health. Research has shown collagen protein is even more satiating than other protein types. One clinical trial found collagen to be 40% more filling than the same quantity of whey, casein or soy. While packed with protein, these muffins are also a great source of antioxidants, thanks to those juicy blueberries. It’ll be hard to resist this fluffy and mouth-watering treat!
