Homemade Peanut Butter Oatmeal Smoothie

Smoothies that are healthy AND taste good are the best! And the ones that require a spoon instead of a straw are even better. This Oatmeal Smoothie is loaded with creamy peanut butter, old fashioned oats, and soy milk. Even though it’s loaded with protein and healthy nutrients, it tastes like dessert in a glass!

This Oatmeal Smoothie recipe makes just enough for one serving. It is the perfect portion size for a snack, breakfast, or midday meal. But you can easily double it if you’re making smoothies for two. (That’s my kind of love language!)

With only a few simple ingredients (only 5!) this smoothie comes together quickly. It can be made in under 5 minutes! Perfect for hectic mornings when you are running out the door.

To make the Oatmeal Smoothie, simply add all of the ingredients to a blender, blend for 30 seconds (or until smooth), and stir. Blend again for another 30 seconds to 60 seconds after stirring to ensure there are no chunks. Pour into a glass (or a bowl), and garnish with banana slices, peanut butter drizzle and oats if desired. Serve immediately or place in the refrigerator until ready to eat. You can also double or triple the recipe to have extra on hand for the week!

Oats: Rolled oats, quick cooking oats or old fashioned oats work best in this smoothie. I would not suggest using steel cut oats in this recipe, as they’ll result in a gritty smoothie.
Creamy Peanut Butter: You can use natural nut butter in place of the peanut butter if you prefer, to cut down on the sugar. Almond or cashew nut butter would both be delicious! To make this smoothie nut free substitute tahini or sunflower seed butter.
Banana: I like using frozen bananas in this smoothie. It keeps the smoothie extra thick, and it’s the perfect excuse to use up all those overripe bananas on your counter or in your freezer! The riper the banana the sweeter this smoothie will be! If using room temperature bananas add in a couple ice cubes to chill down the smoothie and to help thicken it up. If you do not like banana, then I would suggest substituting the banana with greek yogurt.
Soy Milk: Almond milk, cashew milk, oat milk, or regular milk can be substituted for the soy milk. Use your favorite kind! I usually just use whatever we have on hand at the moment.

TIP: For an extra chilled smoothie freeze your banana first! You could also just add some ice cubes too!

tips

Adjust the thickness of this smoothie by adding more or less milk to get your desired consistency. Some people like easily drinkable smoothie and others like super thick smoothies you can eat with a spoon!
The riper your banana the sweeter your smoothie will be! If you want to sweeten up your smoothie more or if you banana wasn’t super ripe add a bit of honey or maple syrup to taste.

oatmeal smoothie variations

Want more protein? Add some plain Greek yogurt, raw nuts (like almonds or walnuts), and flax or more chia seeds. You could even add a scoop of your favorite protein powder!
Incorporate some raw veggies! Spinach is easily hidden in this smoothie, but broccoli or carrots would be good, too!
Need it to be colder? Add some ice!
Add some more fruit! Apples, frozen berries, or kiwi would be great here.
Add a splash of pure vanilla extract for added flavor! Works well with the peanut butter and oatmeal.
Add spice: A touch of cinnamon or ground cloves would be amazing in this! This smoothie reminds me so much of oatmeal in a glass.
Add some cocoa powder or cocoa nibs to make this a chocolate oatmeal smoothie!

how to store smoothies

This smoothie is best enjoyed fresh, but you can store leftovers in the fridge for a couple hours if needed. You can also freeze this prepared smoothie in an ice cube tray or freezer-safe container. Just re-blend it before enjoying later.
