This super creamy, milkshake-like oatmeal smoothie combines oats, raisins, cinnamon, and vanilla for a flavor that tastes just like an oatmeal cookie.

Start Your Day with an Oatmeal Smoothie
This oatmeal smoothie has been on my mind for years. The idea of blending oats into a drink stuck with me after seeing an oat-based breakfast beverage years ago, and I finally developed a version that feels indulgent yet simple.
The result tastes like a cross between a banana milkshake my mom used to make and a warm oatmeal cookie. It’s cool, creamy, and lightly spiced with cinnamon and vanilla, with a satisfying oat-forward texture. Despite having no ice cream, the smoothie achieves a milkshake-like consistency that’s silky and thick.
What you’ll love about this smoothie recipe:
- An easy, grab-and-go breakfast.
- Made with nourishing ingredients like rolled oats, Greek yogurt, and banana.
- Simple to adapt for vegan or gluten-free diets.

Ingredients and Substitutions
- Milk. Any milk works — unsweetened almond milk or skim milk are great choices.
- Greek yogurt. Plain Greek yogurt adds creaminess and protein. Use dairy-free yogurt to make it vegan.
- Banana. Ripe banana gives a naturally creamy texture and sweetness.
- Rolled oats. Uncooked rolled oats thicken the smoothie and add fiber and nutrients. For gluten-free, use certified gluten-free oats.
- Raisins. Raisins add a chewy sweetness and an oatmeal-raisin cookie note.
- Brown sugar. Adds caramel-like sweetness; substitute maple syrup or a softened date for less processed sugar.
- Vanilla extract.
- Ground cinnamon.
- Ice cubes.
Tips and Tricks
Using a fresh, ripe banana gives the smoothest texture, though frozen banana works if you prefer a colder smoothie. Stirring in a scoop of protein powder makes this a more filling breakfast. A drizzle of natural peanut butter on top is a popular and delicious option.
