Prep your blender: Use a high-speed blender or a powerful personal blender. Add frozen berries and frozen banana first.
Add the protein and yogurt: Scoop in the protein powder and Greek yogurt to help everything blend creamy and thick.
Pour in minimal liquid: Add 1/4 cup milk to start.
You can always add more, but you can’t take it out.
Boost with seeds and flavor: Add chia or flax, vanilla, sweetener if using, and a pinch of salt.
Blend low and slow: Pulse or blend on low, stopping to scrape down the sides. If the blade stalls, add 1–2 tablespoons more milk at a time.
Aim for soft-serve texture: The mixture should be thick and hold soft peaks. If it’s too runny, add a handful of extra frozen berries or a few ice cubes and blend again.
Serve: Spoon into a chilled bowl for extra firmness.
Top it: Add fresh fruit, a drizzle of nut butter, a sprinkle of granola, and seeds for crunch and staying power.
