Peanut Butter Corn Flakes Cookies

Peanut Butter Corn Flakes Cookies

When you start baking gluten-free, one thing you get used to is using anything for a flour-substitute. Gluten-free cereals are one of my favorites since you can use them in baked or no-bake desserts and the flavor’s always familiar.

Good ol’ fashioned corn flakes add a nice crunch and chewiness to traditional peanut butter cookies. The flavor is better than any bowl of cereal I’ve ever had.

If you don’t have powdered sugar but still want to give these cookies a special feel to them, drizzle melted chocolate on instead.

    Actually I think these cookies would be best eaten with chocolate hazelnut spread on top.

    (Genius on the cornflakes. Genius.)

    I just made flourless PB cookies last night and I bet the extra crunch of the cornflakes would be delish! Great recipe idea!

    I agree that adding the cereal would take the PB cookie to the next level, just happen to have a box on hand so look forward to trying these!

    If trying a no refined sugars diet, could you substitute honey, agave, maple syrup, or a mixture of two? wondering if the 1 cup sugar measurement would still be the same…

      I have not tried any other sugar alternatives. You could try using 1/2 cup honey and 1/4 cup white sugar. You could also substitute all of the sugar for a lighter refined granular sugar like turbinado or palm sugar but those tend to be much more expensive.
