Oatmeal Smoothie Recipe (High Protein and Healthy!)- TBMW (1)

Ever enjoyedovernight oats? Well, oatmeal smoothies are essentially a thinner and drinkable version of them.

I used to always be someone who’d make smoothies with fruit, which would naturally thicken a smoothie. However, I wanted to make ones without a banana. It’s not that I dislike a banana smoothie (hellobanana breadand breakfast bars), it’s just I found I would always be hungry 5 minutes later!

Adding oatmeal to my smoothie gave it a thickness that a frozen banana would and kept mefull for HOURS. It’sperfect for weight loss,and theadded fiber and proteinkept me going all morning. I’d sometimes forget it was lunchtime!

Why this recipe works

  • Quick and easy. All you do is throw everything into a blender and you are done!
  • Healthy and filling. Thanks to the combination of oats and protein powder, this smoothie keeps you full for hours!
  • Vegan and gluten free. Made completely dairy-free, this is perfect for most diets out there!
  • Creamy texture. This honestly is like drinking a milkshake.

What I love about this oatmeal smoothie recipe is just how much it tastes like having dessert for breakfast! The combination of cocoa powder and the thickness of the smoothie makes it taste like brownie batter!

Oatmeal smoothie ingredients

You’ll love the simple ingredient list to make this recipe. Everything can be found at any grocery store; honestly, you probably have everything in your pantry. Here is what you’ll need:

  • Rolled Oats.Also known as old fashioned oats, these give the smoothie added thickness. Quick oats will also work. Do not use steel cut oats as they cannot be broken down properly.
  • Cocoa Powder.Adds some chocolate flavor, which is always welcome in the mornings. For a richer flavor, use dark or black cocoa powder.
  • Protein Powder. Optional, but highly recommended if you’d like more staying power and extra chocolate flavor.
  • Sweetener. I like using honey or maple syrup, but granulated sugar also works.
  • Chia seeds.Optional, but gives both an extra boost of fiber and nutrients, and added thickness.
  • Peanut Butter or alternative.A spoonful or two of peanut butter oralmond buttergives the smoothie a fabulous flavor and texture. Keep it nut free by using sunflower seed butter or tahini.
  • Milk.To mix it all around! I like using oat milk or almond milk, but use whatever you have on hand.

How to make an oatmeal smoothie

Simply add all your ingredients into a high speed blender and blend well, until your desired texture is achieved. Give it a quick taste and add more sweetness, if desired.

Tips to make the best recipe

  • Oatmeal smoothies are incredibly forgiving. If your smoothie is too thick, continue to add more milk (or water) until your preferred texture.
  • If you’d like a richer flavor, use canned coconut milk instead of the carton variety (we often do this with ourcarrot smoothie).
  • Add ice cubes if you’d like extra thick smoothies.

Oatmeal Shake Variations

The beauty of this smoothie is just how easy it is to customize to your preferences or dietary restrictions. Here is what we’ve tested:

  • Add protein. While oats contain some protein, you can amp it up by adding a scoop (1/4 cup) of your favorite protein powder. I like either casein or brown rice blend.
  • Add yogurt. Greek yogurt or coconut yogurt will add a boost of protein while also making it extra creamy!
  • Make it gluten free. Choose certified gluten free oats instead of standard ones.
  • Cut the sugar. Try using sugar free maple syrup or a brown sugar substitute.
  • Use different grains. Not a fan of oats? Use quinoa flakes or brown rice flakes instead.
  • Change up the fruit. Like any good smoothie, this works with berries, pineapple, coconut, or anything else really.

Storage instructions

To store: Sometimes, I make a double batch of my oat smoothie recipe and store the second in the refrigerator to enjoy as an afternoon snack.

If you intend to consume the smoothie on the same day, it will keep well for under 24 hours there. If you store it longer, you will need to re-blend it before consuming it. Refrigerated smoothies will keep for up to 5 days.

To freeze: As part of my weekly meal prep, I portion out a single oat smoothie serving and freeze it to have later in the week.

The night before I plan to have it for breakfast, I let it the smoothie block thaw at room temperature, and in the morning, I re-blend it. Frozen oatmeal smoothie blocks freeze well for up to 1 month.
