Ingredients

  • 1/2 cup butter
  • 1/2 cup sugar
  • 1/2 cup karo syrup
  • 1/2 cup creamy peanut butter
  • 5 ounces mini marshmallows
  • 5 cup Cornflakes Cereal

Instructions

  • Grease a large baking sheet with nonstick cooking spray or butter.
  • In a large non-stick pot, add your butter and melt over medium heat.  Once the butter has just about melted, add the sugar and karo syrup.  Bring to a rapid boil and boil for 1 minute. 
  • After boiling for 1 minute, reduce the heat slightly and add the marshmallows and peanut butter and stir until combined. Continue to heat over medium-low heat until the marshmallows have almost completely melted.
  • Take the mixture off the heat and add the Cornflakes. Stir carefully until mixed thoroughly, being careful not the crush the cereal. 
  • Using two spoons, carefully drop small mounds of cookie mixture onto the prepared cookie sheet, then let cool completely at room temperature. Enjoy!

Notes

Storing instructions: store in an airtight container at room temperature in a cool dark place for up to 5 days. I don't recommend storing these in the fridge or the freezer because the Cornflakes absorb the condensation quickly, making them mushy.
