This recipe made me laugh, because I eat it almost every single day, yet I realized I’d never actually posted the recipe! I’ve talked about it so many times and yet… I have no recipe to link to! Honestly, this peanut butter protein smoothie has gone through various iterations over the years but my most recent one is my favorite because it doesn’t require protein powder but it’s packed with protein! A few months ago, I started using peanut flour instead of protein powder and it made a world of difference. 1/4 cup of peanut flour has just 90 calories and 10g of protein! While that might not be as much as a typical protein powder, I love knowing that the only ingredient is peanuts and you can’t beat the flavor! Rather than trying to mask a protein powder, I know the more peanut flour I dump in there, the better it’s going to taste! 🙂 I typically buy PB2 from Bell Plantation (they sell it at most grocery stores now!) but I’ve seen a few other products on the market as well.

Ok, enough with the explanation, let’s get into the recipe!

Peanut Butter Protein Smoothie (No Protein Powder Required)

This is my very favorite smoothie recipe! Rather than using protein powder, I use peanut flour!



  • 1 banana, frozen
  • 1/2 cup almond milk (or any milk you like)
  • 1/4 cup peanut flour
  • 1 tbsp peanut butter
  • 4 drops liquid stevia
  • 1 handful of ice


  1. For an ice cream-like texture, freeze your banana overnight. If you don’t have a high speed blender, slice it up first so it’s easier to blend. You can also make it with a regular banana, it just won’t be as thick.
  2. Blend it all up until smoothie and serve immediately!

Of course, you can add a handful of spinach if you want to get in a serving of greens as well!

I would recommend using spinach rather than kale, unless you have a very high speed blender. If you do use kale, be sure to remove the stems as those are quite bitter!

Even though it’s been cold, I’ve been enjoying one of these smoothies at least a few times a week. My favorite way to eat one of these bad boys is in an almost empty peanut butter jar. It’s the perfect way to scrape out the last little bits of peanut butter that hide in all the nooks and crannies.

I’ll be definitely be eating one of these on Saturday morning before I squeeze into this gorgeous number.  
A few friends and I are competing in a gymnastics meet this weekend. It’ll be the first time I’ve worn a leotard since age 11 so that should be interesting. (#ootd) I’m mostly just excited to spend the day cheering on my “teammates” and laughing about how much harder it is to tumble as an adult. Wish me luck!
