Have you ever had chocolate peanut butter Luna bars? Well now you can make your own rice crispy protein bars at home, with only 5 ingredients!

I recommend using brown rice crispies for a healthier version, but if that isn’t available to you, regular rice crispy cereal works just fine. Barbara’s and Nature’s Path make a whole grain brown crispy rice cereal that can be found at most Whole Foods stores.

As quick and easy as it is to grab a bunch of protein bars at the grocery store, I love making my own at home, since the cost tends to add up. This recipe makes 4 bars at a time.

Personally, I love the bars with just the peanut butter flavor, but you also have the option to add a layer of homemade chocolate.

Peanut Butter Rice Crispy Protein Bars
Recipe type: Snack
  • 2 cups crispy rice cereal
  • ¼ cup unsalted peanut butter
  • ¼ cup sticky sweetener (agave nectar or maple syrup)
  • 2 tablespoons vanilla protein powder
  • 1 tsp pure vanilla extract
  • Sea salt, to taste
  • For optional homemade chocolate layer:
  • 1 tbsp cocoa powder
  • 2 tbsp coconut oil
  • 1 tbsp sticky sweetener (agave nectar or maple syrup)
  1. In a large mixing bowl, stir peanut butter, sweetener and vanilla extract together until combined.
  2. Add cereal, protein powder and a dash of sea salt.
  3. Stir well until all rice crispies are coated.
  4. Place parchment paper on a flat surface (baking pan or large plate) and pour mixture onto the paper.
  5. Press down on mixture with a spoon, then mold the outer edges with a spoon so that it makes a giant rectangle shape. (This is easier to do with a spoon than with your hands because the mixture tends to stick to your hands.)
  6. Place in freezer for 30 minutes to harden.
  7. If adding a chocolate layer, melt coconut oil (either in a pot or in the microwave), then stir together with cocoa powder and sweetener until combined.
  8. Remove bars from freezer, spread chocolate sauce on top of bars, and freeze for an additional 10 minutes.
  9. Once the chocolate has hardened, remove bars from freezer again and slice them into small rectangles.
  10. Store in freezer.
