Banana Protein Bars – No Bake, The Best

6 2" bars

The best no bake Banana Protein Bars with a protein packed banana and frosting layer! These banana bread protein bars are low fat, low carb, gluten free and have no added sugar.

I actually had just one banana left from my chunky brownie recipe a few days ago, and I really wanted to try something simple.

No baking needed for these protein bars, and they actually come together like 10 minutes! Great for a meal prep snack or post workout treat.

Ingredients for Banana Protein Bars Recipe:

These banana protein bars are made with simple healthy ingredients, have no sugar or flour, making them a gluten free, dairy free and sugar free homemade protein bar!

  • Mashed Banana
  • Unflavored Protein Powder to replace some of the flour (and carbs) in the recipe for a slightly low carb banana protein bar. I used a whey-caesin blend from Quest Nutrition.
  • Vanilla Protein Powder; Some sweetness in the protein powder banana bar since there’s no added sugar in this recipe. Quest again here.
  • Peanut Butter Powder, also known as Powdered Peanut Butter. I recommend Lakanto for a sugar free version (the code HAYLSKITCHEN gives you a discount). Or you could use the one from PbFit too.
  • Coconut Flour
  • Walnuts

The Protein Frosting layer

These no bake banana protein bars use a high protein and sugar free icing made with Greek yogurt and reduced fat cream cheese.

  • Vanilla Protein Powder for high protein icing.
  • I recommend Quest Vanilla here since it’s whey-caesin and blends well with yogurt.
  • Non fat Greek Yogurt
  • Reduced Fat Cream Cheese

And for the Drizzle:

  • Peanut Butter! Or any other nut or seed butter.
