Ingredients for a strawberry smoothie
  • Frozen strawberries give the smoothie strawberry flavor while making it cold without the need for ice.
  • Banana naturally sweetens the smoothie and thickens it up. Learn how to freeze bananas for smoothies, especially if you have an overripe banana.
  • Peanut butter adds protein and a delicious nutty flavor. You can also swap out the peanut butter for almond butter or sunflower seed butter.
  • Oat milk makes the liquid base of the smoothie and helps it become creamy and smooth. You can use boxed oat milk or homemade oat milk. If you’re on a gluten-free diet, then be sure to use oat milk that is certified gluten-free.

Recipe Tips

  • The nutrition information for this recipe does not include the optional protein powder. See my list of clean protein powder. One scoop of protein powder can add up to 10-20 grams of protein per serving.
  • For a chocolate version of this oat smoothie, add 1-2 tablespoons of cocoa powder or cacao powder.
  • If you don’t have oat milk, any other plant milk or regular milk will work in its place. Almond milk or coconut milk would be great options. If you want it to be really sweet, you could even use orange juice.
  • Store any leftovers in a covered container in the refrigerator for up to 3 days. Or, freeze any extra in ice cube trays or popsicle molds for a healthy treat.

Recipe FAQs

Can I use ice in this smoothie?

You won’t need ice. Frozen strawberries are all this smoothie needs to be perfectly thick and creamy. Ice cubes may not break down all the way and can give it an icy texture.

Can I use fresh strawberries?

Frozen strawberries are what gives this smoothie it’s cold and thick texture. If you only have fresh fruit, simply cut the tops off and place them on a sheet pan to freeze. Once frozen, make the recipe as directed. Just be sure the strawberries are ripe and sweet.

Is oat milk gluten-free?

Oats can be contaminated with gluten, so be sure to look for a certified gluten-free brand of oat milk. Or, you can use certified gluten-free oats to make homemade oat milk.

Can I make this recipe nut-free?

Yes, feel free to replace the peanut butter with chia seeds, sunflower seed butter, or pumpkin seed butter instead.

Can an oat milk smoothie help with breastmilk supply?

Oats have evidence that they can help increase breastmilk supply in breastfeeding mothers, and many women report that oat milk can also help. Feel free to add up to 1/4 cup of rolled oats in this smoothie to help with milk supply.
