Oatmeal Smoothie – Thick, Creamy, NO Banana Required!

This healthy oatmeal smoothie recipe is high protein, high fiber, and super quick to prepare for an almost instant breakfast or post workout snack!

Breakfast Peanut Butter Banana Oatmeal Smoothie

What makes this the best oatmeal smoothie?

No banana required. Unlike many similar oatmeal smoothie recipes, this one can be made without bananas, so it won’t taste like banana.

Delicious creamy texture. If you like EXTRA THICK, filling smoothies, this is the recipe for you.

Protein packed. Each nutritious serving provides 28 grams of protein (or more!), along with whole grains, vitamins, and antioxidants thanks to two cups of fruit in the recipe.

Just 5 ingredients. Whip up your own homemade oat smoothie in seconds!

Healthy oatmeal smoothie ingredients

The recipe is great for breakfast, after school snack, a balanced on-the-go meal, hydrating post workout drink, or weight loss or muscle building. Choose higher or lower calorie ingredients based on your own personal needs.

Oats – Whole grain rolled oats add thickness and nutrition. You can swap them for quick oats or even instant oats. For best taste and texture, do not use steel cut oats.

Want a gluten free oat smoothie? Look for certified gluten free oats or substitute an equal amount of rolled quinoa flakes.

Fruit – Almost anything goes here! It’s a great way to use up whatever fresh or frozen fruit you have on hand, and you can mix and match different fruits to create fun new flavors.

Milk – Use dairy free almond milk or oat milk for a low calorie smoothie. Or try canned coconut milk for a beverage that taste like an oatmeal cookie milkshake and is good for weight gain.

If you choose plant based milk, the drink can also be cholesterol free.

Yogurt – Try soy yogurt or Greek yogurt for the highest protein. Plain or vanilla yogurt are fine as well. While you can substitute more milk instead of yogurt, the results will be less creamy.

(An excellent option for a yogurt free smoothie is to swap all of the yogurt for two thirds cup of ripe, mashed avocado.)

Sweetener – Go with your favorite. I like pure maple syrup or coconut sugar. For an added sugar free smoothie, use erythritol, monk fruit, or stevia to taste.

Add more or less sweetener to taste, if needed. The amount will depend on what type of fruit, yogurt, and milk you choose.

Protein powder (optional) – If you want more protein in the morning, blend in one scoop of your favorite flavored or unsweetened protein powder.

How to make easy oatmeal smoothies

If you want a refreshingly cold oat beverage, I recommend chilling the fruit ahead of time in the refrigerator or freezer.
A tip to yield the creamiest smoothies is to pulse the oats a few times in a blender before adding other ingredients. Or for a smoothie with a slightly chewy oat texture, proceed directly to the next step.
Combine all ingredients in a blender, then blend until evenly mixed and completely smooth. (Those who do not own a high speed blender with a tamper may find it easier to start with non frozen fruit.)
Pour into two glasses, mason jars, or smoothie bowls.
Garnish with sliced fruits, shredded coconut, chia seeds, mini chocolate chips, raisins, or anything else your heart desires.
Enjoy right away. Or cover and refrigerate leftovers for up to five days.

Oatmeal breakfast smoothie flavors

Peanut Butter Banana. Use banana as your fruit of choice, and blend in two to four tablespoons of peanut butter or powdered peanut butter.

Strawberry. Measure two cups of chopped frozen strawberries (stems discarded), or one cup each of strawberries and peaches or raspberries for the fruit.

Apple Cinnamon. Blend in two cups of fresh peeled and sliced apples. Also add half a teaspoon of ground cinnamon and an optional pinch ginger or allspice.

Blueberry Almond. Use blueberries as the fruit, and add two to four tablespoons of almond butter for an ultra creamy oat shake. Top with crunchy granola cereal.

Pumpkin Pie. Substitute canned pumpkin puree for up to a third cup of the yogurt. Add in a fourth teaspoon of cinnamon and an eighth teaspoon of pumpkin pie spice.

Tropical. Use a combination of frozen pineapple and sliced mango or papaya. Throw in a handful of magnesium and iron rich spinach or kale to turn it into a green smoothie.

Chocolate Mocha. Add a tablespoon of cocoa powder and a fourth teaspoon of instant espresso or coffee granules. Choose chocolate milk instead of plain. Or a basic chocolate oatmeal smoothie, omit the instant coffee.

Healthy Oatmeal Breakfast Shake (Dairy Free, Vegan)

1. To yield the best thick, cold oatmeal smoothie, I recommend refrigerating or freezing the fruit ahead of time.
2. If you want a creamy texture, pulse the rolled oats on their own in a blender until soft and powdery. Or for a slightly chewy texture, skip this step.
3. Add the fruit, oats, milk, yogurt, sweetener, and optional protein powder and nut butter to the blender. Process on high until smooth. (If your blender is not high speed with a tamper, you may find it easier to use non frozen fruit.)
4. Pour into glasses, mason jars, or bowls, and add toppings as desired.
5. Enjoy right away, or refrigerate leftovers in a covered cup for up to five days.
