Gather the ingredients and have them close at hand on the counter or table.
Using a knife or wavy cutter, roughly chop 1/2 cups of the candy corn, leaving 1/4 cup whole for the top.
Line an 8"x8" square pan with parchment paper or aluminum foil for easy removal of the treats later. (I tried using waxed paper, but it actually stuck to the treats a bit, so I would advise against using it.)
Melt the Marshmallows
In a large saucepan, melt the butter over medium-low heat. Add the miniature marshmallows to the butter and cook and stir until the marshmallows have melted about halfway. This might take 1-3 minutes, depending on how fresh your marshmallows are.
Prepare the Crispy Treats
Remove marshmallows from heat and add in the vanilla extract and also the chopped candy corn. Quickly stir to combine.
Next add in the crispy rice cereal, and mix together with a long-handled wooden spoon. The mixture is quite thick and sticky at this point.
Place the mixture in the prepared square pan. Using either a spoon or your fingers, lightly press the cereal into the pan. You don’t want to press too hard, however, or the treats won’t be soft and chewy.
Next, decorate the top with the whole candy corn.
Allow the cereal mixture to cool completely before removing from the pan. Once cooled, lift it up using the parchment paper and set it on a cutting board. Using a sharp knife or bench knife, cut into nine squares, or however many pieces you want to serve.
Place squares on a platter to serve. Or if you’ll be serving them at a later time, I suggest tightly wrapping each one individually in plastic wrap and then placing them in a gallon freezer bag. They will store like this for 3-5 days without any problem. I’ve even frozen them for 2 weeks like that, and they were just fine after they were brought back to room temperature. Serves 9
