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.
Tips for Protein Powder Banana Bars with Coconut Flour
These protein powder banana cake bars are really easy to make, but here’s some tips to get it right.
- Use completely ripe/overripe banana since it is more sweet, and will also mash better.
- Use whey-caesin protein powder for the base; It works well with the ratio of ingredients here. If you use a whey protein powder, you might want to increase the coconut flour since it is not as absorbent as whey-caesin.
- Use whey-caesin protein powder for the frosting since it works mixes well with the yogurt and doesn’t turn sticky.
- Mix the dough well to form a smooth mixture, but don’t over-mix since the protein powder might make the texture tough.
- Let the healthy banana bread bars chill before slicing, or they will be too soft.
To store No Bake Banana Bread Bars
This high protein no bake banana bread bars recipe uses Greek yogurt for the frosting layer and can only be kept a few hours on the countertop.
Store homemade banana protein bars in an airtight container in the fridge or freezer so they stay fresh and last longer. They keep in the fridge for up to a 1 week.
To freeze, place no bake banana energy bars in an airtight sealed container, or individually wrapped in plastic wrap and placed in zipper bag; They should keep for 2 or 3 months. Be sure to let them thaw on the counter before eating!

I made this healthy, sugar free and gluten free and low calorie banana bread bar recipe with this particular ingredient list, but here’s some options to choose from.
- Unflavored Protein Powder: Oat flour or Almond flour
- Coconut flour: Try using about 1-1½ cup of Almond Flour
- Greek Yogurt: Coconut Yogurt
Vegan Banana Bars recipe:
Since there’s no milk in this banana protein bar recipe, they can easily be made Vegan with the right ingredients.
Use a plant based protein powder to get a Vegan homemade protein bar; ProteinWorld has a Vegan protein blend that would work well here (code HAYLSKITCHEN for a discount).
You also want to make sure you use coconut yogurt for the frosting layer to make these homemade healthy protein bars.

Tina says
Amazingly delicious; however, it was super runny despite freezing it as directed. I ate them with a fork and the flavor was great. There was no way I had 6 bars as the recipe described and they did not have the same volume/height as the pictures. On the second try, I will use a much smaller pan, not a 9×5 loaf pan. Still a recipe to repeat-thanks!
Haylee Jane Monteiro says
Oh I’m so sorry the recipe turned out runny. Did you by any chance use whey instead of whey-casein? Whey-casein absorbs more moisture compared to whey so if you used a whey only protein powder the mixture would be runnier.
Also for the loaf pan I used a smaller than 9×5 pan which gave me thicker bars.
Amanda says
Could I use all vanilla protien? Instead of half and half.
Haylee Jane Monteiro says
The unflavored is actually a replacement for flour so you can replace the unflavored with oat flour or extra coconut flour.
Heather says
Do you have a suggestion for how to sub peanut butter powder with regular peanut butter?
Thanks
Haylee Jane Monteiro says
You can use 2Tbsp peanut butter and reduce the yogurt to 1Tbsp.
