This peanut butter oatmeal smoothie is quick to make and packed with protein, made with just peanut butter, oats, milk and sweetener. It's the perfect energizer and weight loss smoothie.
This peanut butter oatmeal smoothie is full of fiber, micronutrients, and healthy fats. It also has 12 grams of protein per smoothie! That’s the perfect fuel to wake up your brain and energize your limbs.
Like my other oatmeal recipes, my oatmeal peanut butter bars, and my chocolate oat brownie bars, and even my overnight oats recipe collection, this smoothie is full of rolled oats. I love to add oats to my breakfast recipes because they are inexpensive, wildly nutritious, low in calorie and so useful - they can be blended or sprinkled on almost any recipe.
Why You'll Love This
Quick & easy to make. Just toss the ingredients into a blender, and you have a super creamy protein-rich peanut butter smoothie in a few minutes.
Family & kid-approved. The perfect smoothie for picky breakfast eaters! And easily made with ingredients probably in your kitchen right now.
Perfect for all diets. This peanut butter oatmeal smoothie is dairy free, gluten free, vegan, refined sugar free and even soy free.
Ingredients
Rolled Oats. I use rolled oats in this smoothie, although quick oats would also work. The oats can be eaten raw, and provide a lot of benefits including being heart-healthy, terrific at lowering cholesterol, improving digestion, and great at keeping blood sugar balanced.
Peanut butter. Choose your favorite peanut butter. To raise the health bar, I suggest using a natural version that has only nuts and oil in the ingredients. Creamy or crunch texture is a matter of your preference.
Milk. Use a mix of frozen milk cubes and liquid milk. I freeze full fat coconut milk to thicken my smoothie, but your favorite milk will also work. Try to use one that is not sweetened or flavor, but if you do taste-test before adding any sweetener in case the smoothie is sweet enough.
Maple syrup. This adds a caramel flavor to this peanut butter oatmeal smoothie and it's a plus that this sweetener is refined sugar free.
Vanilla extract, ground cinnamon and salt. These three are small but important flavor boosters to this smoothie.
Equipment Needed
- Fine mesh strainer, to rinse oats
- Measuring cups, spoons

Step by Step Instructions
Here are general steps to make this recipe. For specific measurements and instructions, scroll down to the bottom of this post for the printable recipe card.
Step 1: Loosen the peanut butter by stirring it up in the jar and then measuring it out. If it's hard to stir, you can microwave it for 15 seconds at a time to loosen it up.
Step 2: Put oats in a fine mesh strainer and rinse with cold water to remove phytates.
Step 2: Add all the ingredients to the blender jar, and process. Taste test, and add more oats or peanut butter to thicken or strengthen flavor.
Step 3: Pour into a glass, sprinkle oats and chips, and add a straw. Enjoy!
Recipe Tips
Rinse the oats. Be sure to rinse the oats in a fine mesh strainer, running under cold water for a few seconds, moving the oats around with a spoon so they all get rinsed. This is to remove some of the naturally occurring phytates, a compound found on oats that nature provided to help the plant deter animals from seedlings before they had a chance to grow.
Drink it chilled. For best flavor, make sure the smoothie is chilled before drinking. The frozen milk cubes might make it cold enough, or you might want to refrigerate it before drinking.
Storage
Refrigerated. The smoothie can remain fresh in a closed jar in the refrigerator for about 48 hours. You'll want to stir or shake if the layers have separated.
Frozen. You can make the smoothie ahead of time and pour it into ice cube trays to freeze. Once frozen, add the cubes to freezer bags and store frozen for up to three months.
Substitutions
Rolled oats. You can use quick or instant oats. Do not use steel cut as they won't blend smoothly.
Peanut butter. You can use PB powder instead of peanut butter, just add 3 more milk cubes and add a bit more liquid milk if needed to blend.
Frozen milk cubes. If you don't have time to freeze the milk, just use it in liquid form. Any milk works but full fat coconut milk will add healthy fats and a thicker texture.
Maple syrup. You can use any liquid sweetener, or even dates. To use dates, either make date paste and make a 1:1 swap with maple syrup, or use soften, pitted dates.
Weight Loss Smoothie Options
To increase this smoothie's ability to support weight loss, you have the following options:
1. Add a scoop of protein powder to bulk up the smoothie's ability to support muscle mass and trigger metabolism into burning fat.
2. Add a tablespoon of instant coffee which is known to trigger fat burning.
3. Add a tablespoon of cocoa which turns this peanut butter smoothie into a chocolate smoothie but also boosts metabolism and reduces cravings.
4. Add ½ cup of frozen zucchini or fresh spinach, both add potassium which supports fat burning.
FAQS
Is it OK to put raw oats in a smoothie?
Yes, raw oats are safe to eat and add fiber and nutrition as is. It is true however that cooked oats can be easier to digest in general, but adding this small amount to a smoothie should cause no digestive issues, especially if rinsed first.
Does peanut butter work in smoothies?
It works so well, adding peanut flavor, as well as healthy fats, fiber and protein. It even contributes to a smooth texture.
Does oatmeal in a smoothie keep you full?
Yes, adding rolled oats to smoothies keeps you feeling full much longer than if you were to drink a fruit smoothie. Oatmeal smoothies create a satisfying meal that will help you be less likely to reach for less healthy snacks.
Can I add banana to this smoothie?
You can! I like to make banana-free smoothies because there are so many smoothie recipes built around bananas on the internet, but if you want, add ½ frozen banana to this recipe.
