Ingredient Notes

- Peanut butter
For the healthiest choice, use peanut butter with minimal sweeteners and additives. - Oat milk
Every smoothie needs a liquid base. This recipe uses oat milk, which is creamy and slightly sweet. It also has a mild nutty flavor that’s perfect with peanut butter. Feel free to use other plant-based milks, like almond or coconut milk, as well as dairy options. - Ground cinnamon
A small amount of cinnamon goes a long way in this smoothie. It’s the perfect partner for peanut butter. - Frozen bananas
Bananas add natural sweetness without overtaking the peanut butter. Frozen bananas are used to make the smoothie cold and thick. Always slice the bananas before putting them in the freezer.

You can turn this recipe into a green smoothie by adding a handful of greens. Baby spinach or kale will work best for this drink.
Put the leafy greens in the blender after the peanut butter and before the frozen bananas.
Seeds

These ingredients will also add nutrients like fiber, vitamins, and plant-based protein.

Blender Tips
Liquids go in first.
For the smoothest blend, start with the liquid ingredients. Next, add any nut butters, seeds, and powders, followed with fresh fruit and vegetables, like leafy greens. Finish with heavier ingredients such as ice or frozen fruit.
Cut fruits into chunks.
When freezing fruits for smoothies, be sure to chop them first. Larger pieces are safe for high-speed blenders. However, if your blender is not as powerful, you’ll need to cut the fruit into smaller pieces.
Start on low speed before increasing to high.
Avoid blending on low speed for too long. Otherwise, this can cause the motor to overheat. Start on low then quickly increase to high speed.
Use a blender tamper.
It’s recommended to use a blender tamper when making a smoothie. The tool will let you push the ingredients toward the blades as they spin, ensuring an efficient blend. Most blenders come with their own tamper.

Expert Tips
- When freezing bananas, slice them into coins first. Avoid putting whole frozen bananas in your blender, as this can damage the blades.
- Pick ripe bananas with a yellow peel and some dark brown areas. Don’t use unripe bananas, which have green peels. They’re too bitter and won’t taste good in your drink.
- For a stronger peanut butter flavor, add an extra tablespoon.
- If the smoothie is too thick for your liking, add a splash of milk and blend for another 10 seconds.
- Keep leftover smoothie in an airtight glass jar in the refrigerator. For optimal freshness and texture, enjoy within 1-2 days.
