These gluten-free high-protein cottage cheese cinnamon muffins (with optional blueberries) are ready in about 30 minutes! They’re a great option for make-ahead meal prep — perfect for a quick, healthy breakfast, snack, lunch box item or a light dessert.
Line muffin pan with paper liners or parchment squares. Set aside.
Preheat oven to 350℉.
Place liquid ingredients in blender. Blend on lowest speed until mostly smooth, about 25 seconds.
Measure dry ingredients into large mixing bowl.
Add wet ingredients to dry ingredients, and mix to combine. (If using blueberries, mix them in briefly at the end.) I use a handheld electric mixer on the lowest speed.
Plain version (no cinnamon sugar): Scoop the batter evenly into each muffin tin.Cinnamon Sugar version: Scoop the batter into each muffin tin, filling them about one-third full. Sprinkle approximately 1 teaspoon of the cinnamon sugar mixture evenly over the surface of the batter in each cup. Add the remaining batter on top to fill the tins. Finally, sprinkle the rest of the cinnamon sugar mixture evenly over each muffin.
Bake 20 to 23 minutes, or until puffed, golden brown, and toothpick inserted comes out clean.
