One of my favorite easy and healthy breakfast ideas is the lovely kefir smoothie! I have a multitude of recipes on my blog, and I’ve been making my own milk kefir at home for at least 5 years now, so it’s fair to say I’ve tried many kefir smoothies in my day!
This kefir protein smoothie is a recent favorite, and has been a tasty one that I enjoy alongside my toddler, who can’t seem to get enough of all my yummy kefir smoothies (yes, even my Kefir Green Smoothie). While I would consider him a truly picky eater, he gets a good dose of fruits (and vegetables) through kefir smoothies, and so I’m constantly coming up with new recipes to serve.
A Yummy Kefir Protein Smoothie
This Banana and Peanut Butter Kefir Protein Smoothie is loaded with all-natural protein (no protein powders here!) and is completely satisfying and filling for an easy breakfast or snack.
This recipe makes enough for two moderate portions, or you can drink it all to yourself for a mega-filling smoothie that is packed with 30 grams of protein!
Thanks to the protein in the milk kefir, plus the protein in the peanut butter, you’ll have a hunger crushing kefir smoothie that also happens to taste super delicious.
Let’s get started!
- Milk kefir: This can be store bought, or you can make it yourself at home like I do!
- Banana: You will need 1 large overripe banana. I prefer to use frozen, since this helps thicken the smoothie!
- Peanut Butter: Some natural peanut butter helps add protein, fat, and flavor to this kefir protein smoothie.
- Honey: Raw or regular honey is the perfect choice for a sweetener. The flavor compliments peanut butter and banana perfectly.
- Vanilla extract and cinnamon
A Good Quality Blender
How to Make a Kefir Smoothie with Banana and Peanut Butter
It’s SO easy to make this healthy kefir protein smoothie! Once you have your banana, peanut butter, and other ingredients, all you have to do is add them to the jug of a high powered blender!
Blend your smoothie on high until everything is incorporated and smooth. Scrape down the sides of the blender if needed, and blend again.
Once your smoothie is…well, smooth, taste and adjust for sweetness or additional cinnamon. If you need more of either, add and blend again.
Pour into a large tumbler, or into two pint-sized glasses and serve!
Tips for Success:
- While you can certainly use very ripe, fresh bananas for this kefir smoothie recipe, I would recommend using frozen bananas if possible! They add a lovely thickness to the smoothie, and it’s a great way to use any frozen bananas you have on hand.
- If you don’t have frozen bananas, you can use very ripe, fresh bananas + a few ice cubes to thicken your banana and peanut butter kefir smoothie.
- If you have lots of very ripe bananas on hand, peel them and cut them on half. Place the bananas on a parchment lined baking sheet and place it in the freezer. Once the bananas are completely frozen, transfer to a freezer bag and use in your favorite smoothies in the future. Or thaw for banana bread or banana muffins.
Variations and Substitutions
Dairy Free: If you want this recipe to be dairy free, you can use coconut kefir in place of the milk kefir! While the protein count will be significantly less, it should still be ultra satisfying.
Chocolate, Peanut Butter and Banana: Add 1-2 tablespoons of cocoa or cacao powder to your smoothie. Up the sweetener to your taste, and sprinkle with your favorite chocolate chips.
Almond Butter Kefir Smoothie: If you would prefer, you can use almond butter in place of the peanut butter in this recipe.
Maple Syrup Sweetened: While we sweeten with honey for this recipe, you can substitute with maple syrup if desired. You may need to add more to get the same level of sweetness, since honey is just a tad sweeter.
