Oatmeal Smoothie
A hearty breakfast smoothie is the perfect way to start your day, and this Oatmeal Smoothie is as satisfying as it is simple! With Greek yogurt, peanut butter, banana, and rolled oats, it's a filling and delicious morning meal.

Easy Oatmeal Smoothie Recipe
Some mornings call for a breakfast that's easy to make and filling, and this oatmeal smoothie delivers on both counts. With a mix of oats, Greek yogurt, banana, and peanut butter, it has a creamy texture and just the right balance of sweet and savory flavor.
The oats give it a slightly nutty, toasted taste, while a sweet banana base makes the smoothie rich and thick. It's a great option for busy mornings when you want something quick, tasty, and made with ingredients you probably already have on hand!
Why You'll Love this Recipe
This is one of my favorite smoothie recipes for a number of reasons:
- It's adaptable. The beauty of smoothies is that you can make them your own! Try adding in a ½ cup of frozen fruit of your choice to make the best smoothie for your tastes.
- It's satisfying. The combination of peanut butter and banana makes sure this is a filling smoothie that will keep you satiated all morning!
- The flavor is balanced. The sweetness of the fruit and maple syrup is complemented by the savory oats and yogurt, making this a wonderfully balanced smoothie.

Ingredients
- Banana: This recipe calls for a frozen banana because of the creamy, thick texture it adds to the smoothie.
- Greek yogurt: I recommend using an unsweetened variety. There is plenty of sweetness in the smoothie from the banana and maple syrup!
- Almond milk: This should also be unsweetened for the best results. You can also try this with oat milk.
- Peanut butter: We like using natural peanut butter (no added sugar), but whichever peanut butter you have on hand will work.
- Rolled oats: I prefer to use rolled oats for this recipe, but instant or quick oats work just as well.
- Vanilla extract: Adds a warm, sweet flavor to the recipe.
- Protein powder: You can use your protein powder of choice, whether that is whey, soy, or even pea protein.
- Maple syrup: This is optional and to taste. If you prefer a sweeter smoothie, adding a bit of maple syrup is delicious!
If using sweetened protein powder, taste the smoothie first before adding maple syrup.
Substitutions and Variations
Spices: Try adding some warm spices like cinnamon or nutmeg to make this smoothie taste like an oatmeal cookie.
Different Fruit: Try adding ½ cup of frozen strawberries for a strawberry oatmeal smoothie or the same amount of frozen blueberries for a blueberry banana version!
Avocado: Adding half of an avocado will thicken the smoothie and add more creaminess.
Vegan: To make this a vegan oatmeal smoothie, swap the Greek yogurt for a vegan variety and choose a vegan protein powder like pea protein.
How to Make Oatmeal Smoothies

Madison's Pro Smoothie Tips:
This banana oatmeal smoothie is as easy as can be. Follow these tips for the best result!
- Scrape the sides of the blender. Peanut butter can sometimes stick to the sides of the blender, so pause to scrape them down with a rubber spatula if needed to ensure everything blends evenly.
- Use frozen banana for the best texture. A frozen banana makes the smoothie thicker and creamier without needing ice, which can water down the flavor of the smoothie.
- Adjust the sweetness to taste. Start with a small amount of maple syrup, then add more if needed. The natural sweetness of the banana may be enough!
- Don't forget to clean your blender properly! The oats in particular can stick onto your blender blades, so this method of cleaning will help greatly!
FAQ
