Gather two tablespoons of creamy peanut butter and one cup of ripe bananas, either fresh or frozen. Peel and slice fresh bananas for easier blending.

Place the peanut butter and sliced bananas into a high-speed blender. Optionally, add a splash of milk or yogurt for sweetness.

Blend on medium-high setting for 30-45 seconds until smooth. Add more liquid if needed for consistency.

Pour into a glass and garnish with a slice of banana or chopped nuts if desired.

Rinse the blender with warm water and a drop of soap to clean it.
