A creamy, protein-packed smoothie inspired by the classic Czech kolache pastry, blending sweet fruit, vanilla protein, and a hint of cinnamon for a satisfying breakfast or post-workout treat.
For a thicker smoothie, use frozen banana instead of some berries. Store leftovers in an airtight container in the refrigerator for up to 24 hours (shake well before drinking). For meal prep, freeze all ingredients except milk in individual bags, then blend with liquid when ready to serve.
