Ingredients for No Bake Peanut Butter Bars

Ingredients and Variations

CEREAL Corn flakes and crispy rice cereal make up the bulk of this crunchy recipe, but other cereals will work!

PEANUT BUTTER I use smooth peanut butter as it is what we keep on hand but crunchy will work too. This recipe has not been tested with other butters or natural peanut butter which may affect the consistency.

SWEETENERS Corn syrup helps hold these together while the brown sugar adds a bit of sweetness and flavor.

CHOCOLATE Chocolate chips are the perfect topping for all things peanut butter! Adding a touch of vegetable oil (or even butter or coconut oil) helps keep the chocolate layer from cracking as the bars are cut.


  • Feel free to add cinnamon, apple pie spice, even pumpkin pie spice.
  • We also like sliced almonds, chopped walnuts, or even pecans added to the mix.
  • For extra healthy peanut butter bars, add a tablespoon or so of flax meal for extra omega 3 benefits!
  • Switch out the chocolate chips for white chocolate and sprinkle red and green sugar crystals for a festive dessert bar without the baking!

  1. I made these yesterday and when I cut them to serve, the cereal mix didn’t stick together very well. I’m wondering what I did wrong. They still tasted great, but I had to scoop the cereal mixture from the bottom of the pan.4 stars

    1. We haven’t had that issue with this recipe Nathalie. I’d guess that you may not have pressed it into the pan hard enough. Glad you enjoyed them nonetheless!

  2. This was such a fast and easy recipe and it tasted delicious! I am trying to reduce the added/processed sugars in my diet, so I opted for natural peanut butter, sugar free chocolate chips, honey to replace the corn syrup, and a keto brown sugar replacement! It all turned out perfect! :)5 stars
