- 1/2 cup plain Greek yogurt

- 1 teaspoon honey, optional
- 1/2 teaspoon vanilla extract
- 1/4 teaspoon cinnamon

Instructions
Step 1: Load the blender
Add milk first, followed by yogurt, peanut butter, oats, banana, vanilla, cinnamon, salt, and honey if using.

Step 2: Blend
Blend on high until completely smooth, about 45 seconds.
Step 3: Adjust
Add a splash of milk for a thinner smoothie or ice for a thicker, colder texture.

Step 4: Taste
Adjust sweetness only after blending because ripe bananas may provide enough.

Pour into two glasses and serve immediately.

How to Store Leftovers
Peanut Butter Banana Smoothie is best immediately. If necessary, refrigerate it in a tightly covered container for up to 24 hours, then shake or blend again because separation is normal.
