The perfect homemade Kit Kat Protein Bars made with protein powder, peanut butter powder and rice cake thins for the crunch. Healthy Kit Kat bars are gluten free and sugar free too!

I’d been holding off on trying this healthy Kit Kat bar recipe for a while just because I wanted those rice cake thins.


Definitely worth the try because these bars are crunchy and taste so perfect! A really easy snack or dessert to satisfy those candy cravings.

Ingredients for Kit Kat Protein Bars:

These candy inspired Kit Kat protein bars are made with rice cakes thins and simple healthy ingredients, with no sugar or milk; A great sugar free and Vegan homemade protein bar!

  • Rice Cake Thins
  • Chocolate Protein Powder for high protein magic cookie bar, and also replace the sweetener.
    I recommend Protein World Slender Blend or ProteinWorld Whey for this recipe to keep it sugar free; Use the code HAYLSKITCHEN for a discount.
    Another option would be Quest.
  • 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.
  • Unsweetened Almond Milk

For the Chocolate Coating for a homemade Kit Kat Candy effect:

  • Chocolate Chips: The sugar free from Lakanto again here (same code HAYLSKITCHEN for a discount) 
  • A bit of Coconut Oil

Tips for perfect Homemade Kit Kat Bars without Peanut Butter

  • Use sharp knife to cut rice cakes so they don’t break.
  • Add milk only a little at a time or the mixture will be too runny.
  • Spread paste on rice cakes gently; They can break very easily.
  • Stir chocolate partway when melting so it doesn’t burn.

To store Rice Cake Protein Bars for Snack

To store homemade rice cake protein bars, place in the fridge for 3-4 days.

They won’t be as crunchy though.

To freeze, place protein rice cake Kit Kat bars in 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!

Other ingredients for Healthy Alternatives to Kit Kat

I made these high protein sugar free Kit Kat candy bars with cornflakes with this ingredient list, but here’s some options to choose from.

  • Peanut Butter Powder: About 3 tablespoon Peanut butter, but start with only 1½ tablespoon of water at a time.
    I recommend American Dream Nut Butter’s flavored PBs (code HAYLSKITCHEN for a discount here too)
  • Rice Cake Thins: Graham crackers or cub crackers
  • Chocolate Protein Powder: Use a vanilla
  • Protein Powder: Try 1:1 Zero Calorie Sugar Substitute; I use Lakanto, to keep this recipe sugar free;  (code HAYLSKITCHEN for a discount here too)

Add less water in this case.

Vegan Kit Kat Candy Bars

Since there’s no milk in this dairy free recipe, these Kit Kat protein candy bars can easily be made Vegan with the right ingredients.

Use a plant based protein powder to get a Vegan Kit Kat bar; ProteinWorld has a Vegan protein blend as well.

You also want to make sure you use dairy free chocolate chips too.

    Okay rice cake thins for the wafer in these is just genius. I sometimes felt the wafers in actual kit kat was a bit too thin but with these I can get the crunch and the chocolate. Perfect ratio ??
