I partnered with Bob's Red Mill for another quick and easy recipe for you gals on the go. While they are a sponsor, I only share products I can stand behind. This is my 100% honest review of the BRM Homestyle Peanut Butter Granola; long story short, it's bomb.
Oat Smoothie With No Oats
The best oat smoothie is not made with rolled oats. That’s right, I said it. If you want a next-level oat smoothie or shake, put down the oatmeal and pick up some Bob’s Redmill Peanut Butter Granola.
Technically there are still oats but hear me out. Plain rolled oats are like a blank canvas and take on the flavor of whatever you add. On the other hand, this granola is made from oven-baked oats with a blend of creamy peanut butter and real maple syrup. That’s instant toasted flavor baked into the oats, like a cookie. It is the perfect flavor foundation for this oh-so-creamy and deliciously comforting smoothie.
Ingredients Needed For Oat Smoothie Recipe
- Peanut butter granola: This flavor Bob’s Redmill Homestyle Granola, is packed with toasted peanut buttery goodness. I add it both in the smoothie and on top of the smoothie as a crunchy garnish.
- Frozen Banana: Bananas add natural sweetness and help thicken the smoothie giving it its creamy texture. If you don’t have frozen bananas, don’t worry. Just use a regular banana and add a few ice cubes while blending.
There's no such thing as a rotten banana. Next time you have overripe bananas at home, don't throw them away; instead, peel and chop them into chunks, store them in a freezer bag. They will add thickness, natural sweetness, and creaminess to your shake or smoothie.
- Chocolate protein powder (optional): I just love the flavor combo of peanut butter, banana, and chocolate, but this shake is also great with vanilla protein powder. To make vegan, use a vegan certified protein powder.
- Salt: A small pinch of salt is added to enhance the overall flavor of the smoothie and bring out the sweetness of the other ingredients.
- Cinnamon: add to make the smoothie extra cozy and has anti-inflammatory properties.
- Milk: Smoothie thickness is a personal preference, and your milk helps you achieve the right consistency. I recommend starting with 3/4 cup of your desired milk and adding 2-3 tablespoons at a time until you get it just right.
- Ground coffee (optional): A little coffee brings out the flavor of the peanut butter. It adds a bit of natural caffeine, perfect for that early morning fuel.
- Ice (optional): Sometimes, I’ll add a few ice cubes at the end to make my smoothie thicker and colder.
Tools Needed To Make This Recipe
Like with most shakes and smoothies, you’ll need a high-powered blender. I love my Breville Super Q Blender, but any powerful blender will do.
How To Make Oat Protein Smoothie
Creating the perfect oat protein shake is easy, just toss all ingredients into a blender, blend for about 30 seconds or until everything is smooth. Remove the lid to stir to make sure there are no chunks left. You can also scrape the sides if any ingredients got stuck. Blend for another 30 seconds then pour it into a glass sprinkle additional granola for garnishing. Enjoy it while it’s fresh and cold!
Can I double this recipe?
Yes! You can easily double the recipe to serve two or freeze half for a later date. Simply blend all the ingredients in batches if needed, depending on your blender size.
Tip: If you want to make this into a "smoothie bowl," double the frozen banana, reduce the milk to 1/3 cup so it's extra thick, and use a taper to help the ingredients blend. Sprinkle with more Bob's Red Mill Peanut Butter Granola and any other toppings you love.
Can I use old fashioned rolled oats or rolled oats?
This smoothie is bursting with flavor and only has a few ingredients because a ton of flavor is baked into the Bob’s Redmill Peanut Butter Granola. Using granola cuts a few steps in the prep but if you only have oats or oatmeal, I would add 1 tablespoon of peanut butter and 1/2 teaspoon of maple syrup to achieve comparable flavor in the recipe.
What’s the difference between a protein shake and a smoothie?
So, the main difference between a protein shake and a smoothie is that a shake has protein in it, and a smoothie doesn’t always have it. But both are yummy blended drinks that you can make with all sorts of tasty ingredients. Smoothies tend to have lots of fruit and vegetables and be a bit more fruity, while protein shakes are creamier because of the protein powder or other protein sources.
Storage and Freezing Instructions
This smoothie is best enjoyed fresh, but you can store leftovers in the fridge for a couple of hours if needed. You can also freeze this prepared smoothie in an ice cube tray and just re-blend it before enjoying it later.
