What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use a frozen banana for a thick, milkshake-like texture without ice diluting the flavor.
- 2Start the blender on low speed to prevent powder from flying, then increase to high for 30–45 seconds.
- 3If your banana isn't frozen, add 3–4 ice cubes and reduce the milk by 2–3 tablespoons to maintain thickness.
- 4For a richer flavor, let the milk get ice-cold and consider using whole milk or a splash of cream.
- 5Blend the wet ingredients first to help the protein powder incorporate smoothly without clumps.
- 6Serve immediately after blending; the shake will thin out as it sits.
