Oatmeal Smoothie

DF GF V VG

This protein-packed oatmeal smoothie tastes like a cinnamon oatmeal cookie, but it’s super healthy and filling. Plus, it’s made with only 6 simple ingredients!

Love having oatmeal for breakfast but want to switch things up? You’re in luck because today I’m sharing a recipe for an oatmeal smoothie that tastes just like you’re eating an old fashioned cinnamon oatmeal cookie!

Ingredients Needed:

The best part is that you can get all of the ingredients for this smoothie at your local grocery store. No fancy ingredients here! And lastly, this smoothie takes less than 5 minutes to whip up.

  • frozen banana – frozen banana helps thicken the smoothie and adds a little sweetness.
  • unsweetened almond milk or oat milk – any milk will work, but I prefer almond milk or oat milk. If you want extra oat flavor and more creaminess, go for the oat milk!
  • old fashioned oats – you can’t have an oatmeal smoothie without oats! Be sure to grab gluten free oats if need be. 
  • vanilla protein powder – I love adding protein powder to my smoothies to make them more filling! I think the vanilla flavor blends really with this particular smoothie. I like using Nuzest protein powder. You can use my code eatingbirdfood for 15% off your order.
  • cinnamon – for a bit of sweet spice and oatmeal cookie flavor!
  • vanilla extract – a great flavor enhancer!

Adding Oats to Smoothies

Yes, adding oats (or ever leftover cooked oats) is a thing! Adding rolled oats to your smoothie is perfectly safe and gives the smoothie a thick and creamy texture. The oats also add a bit of extra nutrition, including fiber, which will help make your smoothie more satisfying and filling.

As for what type of oats to use for smoothies. I recommend old fashioned rolled oats or quick oats. Both of these options are pre-cooked and will blend up just fine in your blender. I don’t recommend steel cut oats as they are the least processed, quite hard and will be harder to blend and more difficult to digest.

      I had 2 medjool dates to use up so I used those instead of banana and added peanut butter. It tasted wonderful 🙂
