Add liquids first. Pour the milk into your blender.
This helps the blades move smoothly and prevents clumping.
Add the banana. Use a ripe banana for sweetness. If you want a thicker, ice-cream-like texture, use a frozen banana.
Scoop in the protein powder. Choose a flavor that complements peanut butter. Vanilla, chocolate, or unflavored all work well.
Add peanut butter. Drop in two tablespoons.
If you’re counting calories, start with one and adjust later.
Season it. Add vanilla, a pinch of cinnamon, and a tiny pinch of salt if using. These small touches make a big difference.
Ice goes last. Add the ice on top. This keeps it from jamming the blades at the start.
Blend until smooth. Start low, then increase to high.
Blend 30–45 seconds until creamy and no chunks remain.
Taste and adjust. If it’s too thick, add more milk. If you want it sweeter, add a touch of honey or maple. Blend again for a few seconds.
Serve right away. Pour into a chilled glass for the best texture.
