Recipe Tips & Substitutions

  • 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, 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 (see my round-up of the best dairy-free milk recipes). Almond milk or coconut milk would be great options. If you want it to be really sweet, you could even use orange juice.

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 or pumpkin seed butter instead.
