Oatmeal smoothie

If there was an award for most faithful oatmeal fans, we’d be the winners! This oatmeal is on our table every single day, and baked oatmeal and oatmeal bars are one of our ultimate treats. I do think I could eat it for every meal (no exaggeration). So here’s yet another way to eat this healthy whole grain: the perfect Oatmeal Smoothie! Blend up oats with banana and peanut butter and it tastes, oddly enough, just like a bowl of oatmeal! The puree is perfectly scented with cinnamon and ultra creamy! It went over so well in our house, it’s one of our favorite smoothies yet.

Oatmeal smoothie ingredients

You’ll need a handful of ingredients for this oatmeal smoothie, and if you’re anything like us, you’ll already have them on hand. Here’s what to know:

  • Old Fashioned rolled oats: Use regular old oats: don’t even think about substituting steel cut oats! They’re the texture of rice so much too hard to blend
  • Bananas: Room temperature! You’re welcome
  • Frozen pineapple: Trust us: it makes just the right sweetness and icy texture!
  • Peanut butter: Adds creaminess and protein: for nut allergies, use sunflower butter
  • Greek yogurt: Yogurt also adds loads of protein and a creamy body
  • Milk: Use normal milk or the vegan variation below
  • Vanilla: The extract develops the flavor just enough
  • Cinnamon and salt: Cinnamon is perfect for the oatmeal vibe
  • Ice: Ice achieves just the right icy texture

Flavor variations and add-ins!

Throw the ingredients into a blender and whiz them into a beautiful creamy puree: and you’ve got an oatmeal smoothie! Take one sip and it tastes remarkably like…well, oatmeal. The cinnamon is key to the oatmeal vibe. Here are a few more tweaks to this banana oatmeal smoothie you can do to vary it up:

  • Customize the cinnamon: We’ve listed a range in the recipe below. Use the 1/2 teaspoon cinnamon for a very forward spiced flavor.
  • Vary the nut butter: Use any type of nut butter in place of the peanut butter, like almond butter, cashew butter, or pecan butter.
  • Add chai spices: Substitute cozy chai spices for the cinnamon.

Make it a vegan oatmeal smoothie

This banana oatmeal smoothie has Greek yogurt, like many of our smoothie recipes, to load on protein and healthy probiotics. But want a vegan smoothie? Try it with oat milk.

  • Use oat milk (and skip the yogurt). An oatmeal smoothie needs oat milk, right? We love using this dairy free milk in smoothies: it’s very creamy and makes for a good body. It’s easy to find at your local grocery. Use slightly more dairy free milk until the smoothie comes together.
  • Add back some protein! You’ll lose some protein from removing the yogurt. Here are some ideas for adding plant based protein: add more peanut butter, or throw in up to 2 tablespoons chia seeds.

Smoothie storage

This oatmeal smoothie is best right after you blend it up. But you can make smoothies in advance! Store them up to 1 day, refrigerated in a sealed container or a mason jar with the lid on. The smoothie may separate, which is perfectly natural. Just shake it up and you’re good to go!
