Start by giving the candy corn a quick rough chop; a few cuts will do the trick, as you want recognizable chunks in the final treats.
In a large saucepan over low heat, add the butter and stir it gently until fully melted. Next, pour in the mini marshmallows and stir them continuously until they melt into a smooth, gooey mixture.
Take the pan off the heat and fold in the chopped candy corn, stirring just until it’s well distributed.
Now, add the Rice Krispies cereal, stirring until each piece is thoroughly coated in the marshmallow mixture.
Prepare a 9x13 springform pan by generously coating it with cooking spray or lining it with wax paper. Transfer the candy corn Rice Krispies mixture into the prepared pan, then use a greased spatula to spread it evenly. For an extra festive touch, press a few additional candy corn pieces on top.
Let the treats cool completely, then slice into 12 squares. Enjoy this Halloween treat with a sweet, spooky twist!
