Freeze the banana: Slice a ripe banana and freeze it for at least 2 hours or overnight. Frozen banana is key for that thick, creamy texture.
Layer the blender: Add milk to the blender first, then oats, peanut butter, frozen banana, and any optional add-ins like vanilla or cinnamon.
Blend until smooth: Start on low to break up the banana, then increase to high.
Blend 30β45 seconds, until creamy with no chunks.
Taste and adjust: If you want it sweeter, add honey or maple syrup. For a thicker shake, add a few ice cubes or a bit more frozen banana.
Serve right away: Pour into a glass and enjoy while itβs cold and silky.
