My kids love smoothies! One of their favorites is this kid-friendly Peanut Butter and Banana Green Smoothie – it’s a great source of protein without protein powder, for breakfast or anytime!


Seriously, I love smoothies. There are so many different ways you can make them. I started having a smoothie for breakfast about four years ago, and they serve to both keep me full until nearly lunch (if made with some protein) and help me keep off extra weight. 

My kids also like smoothies too, although they don’t like the protein powder that I use. So I decided to find a different way to incorporate protein into our smoothies (greek yogurt and peanut butter) as well as some vitamin C through something other than juice (spinach!). 

This resulted in one of our favorites, the Peanut Butter and Banana Green Smoothie!

It’s a delicious peanut butter banana protein smoothie recipe made without protein powder. 

I’m excited to share it with you today.

Do you need to have exact ingredients to make smoothies?

Yes and no. After many years of experimentation, I’ve found that it’s best to start out with an already-created recipe. Then, as you get used to what you want the consistency of your smoothie to be, you can start to eyeball your amounts of ingredients. 

A helpful smoothie ratio is:

  • 3/4 to 1 cup liquid (milk or juice)
  • 1 cup yogurt
  • 1 cup fruit 
  • 1 cup greens (such as spinach or mixed greens)
  • 1-2 tbsp fat (nut butter, flaxseed etc)
  • Protein powder (if desired)
  • Soft fruit (like avocado or banana) – optional
  • 1/2 cup ice cubes (if you don’t use frozen fruit)

This doesn’t have to be exact but it is a guide to get you started!
