Blend the base: In a blender, combine cottage cheese, banana, vanilla extract, cinnamon, lemon zest, a pinch of salt, and 2 tablespoons milk. Blend until smooth and creamy.
Add sweetness and protein: Add the protein powder and honey or maple syrup. Blend again.
If it’s too thick, add more milk 1 tablespoon at a time until you reach a thick, spoonable texture.
Stir in the “muffin” bits: Pour the mixture into a bowl. Fold in oats, chia or flax (if using), and most of the blueberries, saving a few for topping.
Rest briefly: Let the bowl sit for 3–5 minutes so the oats and seeds soften and thicken the mixture slightly.
Top and serve: Add remaining blueberries, a sprinkle of cinnamon, and any crunchy toppings you like. Taste and adjust sweetness if needed.
