This oatmeal smoothie tastes just like a cinnamon oatmeal cookie. It’s healthy, packed with over 20 grams of protein and makes for a great breakfast or post-workout snack!
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 but in smoothie form.
Why You Gotta Try This One
I love a smoothie that feels like real breakfast, and this one does exactly that. It’s cozy, creamy, and gives big cinnamon-oat energy without requiring a single pot or pan. Just toss everything in the blender and you’re good to go. The oats make it thick and satisfying, and the fact that it’s packed with protein means you won’t be hungry again in an hour. Total win.
Ingredients Needed:
- frozen banana – frozen banana helps to thicken this smoothie and adds a little sweetness. Be sure to check out my guide for how to freeze bananas.
- 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. My fave brand is Bob’s Red Mill gluten free old fashioned rolled oats.
- vanilla protein powder – I love adding protein powder to my smoothies to make them more filling! I think the vanilla flavor blends really well with this particular smoothie. I like using Nuzest‘s smooth vanilla protein powder. You can use my code eatingbirdfood for 15% off your order.
- cinnamon – for a bit of sweet spice and oatmeal cookie flavor!
- pure vanilla extract – a great flavor enhancer!
Make It Your Own
Want to put your own spin on this oatmeal smoothie? Here are a few ideas to play with:
- Add a nutty swirl: Blend in a spoonful of almond butter or peanut butter for extra richness and a flavor combo that’s super comforting.
- Top it like a bowl: Pour your smoothie into a glass or bowl and add toppings like sliced banana, crushed walnuts, or a sprinkle of homemade granola for crunch.
- Make it chocolatey: Add a teaspoon of cocoa powder or use chocolate protein powder to turn this into a chocolate oatmeal cookie smoothie. Trust me, it works.
- Boost the nutrition: Want to level it up even more? Add chia seeds, flaxseed, or even a handful of spinach. You won’t taste it, but you’ll get all the extra benefits.
How to Make
This oatmeal smoothie is super quick and easy—perfect for busy mornings when you want something satisfying and nourishing.
Step 1: Add all your ingredients to a high-powered blender and blend until smooth.
Step 2: Pour into a glass or bowl and add your favorite toppings, if desired. Sip or spoon and enjoy!
Brittany’s Tip
Sweetness matters: The frozen banana adds natural sweetness, so if you’re skipping it or not replacing it with another sweet fruit, consider adding a little maple syrup, agave, honey, or stevia to balance the flavor.

Oatmeal Smoothie
Ingredients
- 1 frozen banana, (chopped into chunks)
- ½ cup unsweetened almond milk , or oat milk, plus more as needed to reach desired consistency
- 3 Tablespoons old fashioned rolled oats
- 1 scoop (25 grams) vanilla protein powder, I used Nuzest
- ½ teaspoon cinnamon
- ½ teaspoon pure vanilla extract
Instructions
- Place banana, milk, oats, protein powder, cinnamon, and vanilla in a high-powered blender and blend until smooth.
- If the smoothie is too thick, add a little more milk.
- Pour into a glass or bowl (depending on whether you want to use a spoon or straw) and top with your favorite smoothie toppings.
Notes
- No banana? Frozen banana makes this smoothie sweet and creamy, but you’ve got options! Try using ice or frozen milk cubes for texture, or frozen cauliflower rice, frozen zucchini, or a bit of avocado for creaminess. Just note that if you skip the banana, you’ll likely want to add a little extra sweetener like maple syrup, honey, or dates.
- Oats: Rolled oats or quick oats both work well and blend easily. Skip steel-cut oats, which are harder to blend and not ideal for smoothies.
- Protein powder: I like vanilla protein powder here because it boosts the flavor and helps make the smoothie more filling.
- Storage: This smoothie is best enjoyed right after blending, but you can store leftovers in a sealed jar in the fridge for up to 24 hours. Give it a good shake before drinking.

Yummy! Tastes kind of like an oatmeal cookie. I wish it would’ve come out thicker and creamer. Overall tastes good and I will make it again
Yay, so glad you liked the flavor, Feefee! For a thicker and creamier texture next time, you could reduce the almond milk a bit or add a few more frozen banana chunks or even some ice. A spoonful of Greek yogurt or cottage cheese would also work great if you’re okay with dairy. Thanks for giving it a try and sharing your feedback!
I used vanilla oat milk and added a heaping spoonful of Greek Gods Honey Yogurt- OMG yum! My husband and I both agreed this may be the best smoothie we’ve ever had. And I make A LOT of smoothies. Your overnight oats are how I originally found your website but every recipe being delicious is what keeps me coming back :).
Aww this made my day! So glad you and your husband loved the smoothie—and that Greek Gods honey yogurt addition sounds next-level! Love that you found my site from the overnight oats recipe and that you’ve been enjoying all the recipes. 🙂 Thanks for being here!
