Prep the base: Add milk, yogurt, and vanilla to your blender first. Liquids at the bottom help everything blend smoothly.
Add the dry ingredients: Toss in oats, protein powder, cinnamon, and a pinch of salt.
Sweeten and enrich: Add the frozen banana and maple syrup or date. Include nut butter or seeds if using.
Blend until creamy: Start low, then increase to high for 30–45 seconds.
If it’s too thick, splash in more milk. If too thin, add a few ice cubes or a bit more oats.
Taste and adjust: Add extra cinnamon for more “roll” flavor or a touch more sweetener if you prefer.
Serve with a swirl: For a playful “icing” effect, drizzle the yogurt-maple mixture on top and sprinkle with a pinch of cinnamon.
