Optional mix-ins: 1/2 scoop protein powder (vanilla or chocolate)1 tablespoon flaxseed meal, 1 tablespoon chia seeds
Place all of the ingredients in a blender in the order listed: almond milk, banana, peanut butter, Greek yogurt, cinnamon, and any extra mix-ins.
Blend until smooth. If you'd like the smoothie thicker, add a few ice cubes and blend again. Pour and enjoy!
If you are not using a high-powered blender, you may need to thin the smoothie with more almond milk to get it to blend properly. A good approach is to add the frozen banana in stages, blending between each.
TO STORE: Refrigerate leftover smoothies in airtight storage containers or jars for up to 1 day.
TO FREEZE: Freeze smoothies in freezer-safe jars or ice cube trays for up to 3 months. Let the jars thaw overnight in the refrigerator before serving. If using an ice cube tray, toss the frozen cubes into the blender for a smoothie on demand.
