If you cannot find corn syrup, there are substitutes that can be used. Any other type of syrup will work to replace the corn syrup.

How to Store Peanut Butter Cornflake Cookies

Store the cookies in an airtight container to keep them fresh for up to a week. Alternately, you can freeze them and thaw them out as needed.

I like to make these cookies and freeze half of it so I can pull out a batch anytime I need to make a quick treat.

Tips for Make These No Bake Peanut Butter Cookies

  • If the cookie dough is too sticky, add a little more cornflakes to it.
  • If the cookies are not holding together well, put them in the fridge for 30 minutes before serving.
  • Be sure to use a good quality creamy peanut butter in this recipe for the best results.
  • The cookies can also be made into bars instead of cookies. Just press the mixture into an 8×8 inch baking dish and then cut into squares after they have cooled.
  • For a chocolate version of this recipe, melt some chocolate chips (or chopped chocolate) and drizzle over top of the cooled cookies.
  • Adding a 1/4 teaspoon of salt to the recipe helps bring out the flavors of the peanut butter and cornflakes.
  • You can also add in some chopped nuts, such as peanuts or almonds, to the recipe for extra crunch.
  • If you want a bit more sweetness to your cookies, consider adding in a few tablespoons of powdered sugar to the mixture at the end.
  • For softer cookies, add in a tablespoon or two of milk when mixing the peanut butter and cornflake mixture.
  • Try adding some sprinkles on top of these cookies for extra festive flair!
