Low-FODMAP No-Bake Peanut Butter Cereal Bars; Gluten-free, Vegan

Although this recipe has not been tested, a single serving should be low-FODMAP based on the ingredients

Serves: 12

Prep/Cook time: 15 min

Equipment: 13 by 9 inch casserole dish


  • 3/4 cup sugar (vegan certified if necessary)
  • 3/4 cup light corn syrup
  • 16 ounces (1 jar) all-natural smooth peanut butter
    • Note: Some natural peanut butters are more thick, with less oil than others.  The oils actually help the butter get smooth and stirrable. If your jar of peanut butter is dry, then feel free to add 1 tbsp of peanut or canola oil when mixing to help the consistency
  • 2 & ¼ cups Cheerios oat cereal
  • 2 & ¼ cups Chex Corn cereal
  • 1 tsp vanilla extract
  • ½ tsp salt if not added to your peanut butter


  • Prepare a 13 by 9 inch casserole baking pan- grease lightly with baking spray or vegetable shortening
  • In a large saucepan, place sugar, corn syrup, vanilla and peanut butter over medium-low heat
  • Stir constantly until the sugar is dissolved and the mixture is beginning to bubble very slightly, but not boiling
  • Remove from the heat and quickly stir in two cereals.  Make sure your pan is not too hot on the bottom or the peanut butter may start to thicken and seize up.  If it gets too hot to stir, then flip it over into your prepared pan to stir and spread there
  • Spread quickly into lightly greased prepared pan and smooth top with spatula
  • Cut into bars while warm, then let cool to serve

  1. Way to much sugar & peanut butter I kept adding cereal and I used cornflakes & crispix because the bad stuff about Cheerios. Maybe oatmeal would have been better but I feel like I wasted a lot of sugar & peanut butter for nothing!

  2. Easy chewy treats!

    I was searching for an easy recipe after so much cooking for Thanksgiving and was happy to find a no baking choice for low FODMAP. This was a big hit with my kids (and me!). Very healthy snack with all the fiber in the cereals. Thank you!

    1. Angela,
