Celebrate Halloween with these adorable, tasty Frankenstein Rice Krispie Treats and the best part about them is that you can make them today using simple ingredients you already have on hand!
Can you believe there’s only 10 more days until Halloween! Where has this month gone? But seriously, Halloween is one of my favorite days of the year (next to Christmas and my birthday of course!) One of the best parts of being a mom at Halloween is the fun of sharing it with my kids and my kids like probably most kids love Rice Krispie Treats. Oh who am I kidding… I love Rice Krispie Treats!
I love these gooey marshmallow little squares of crisp rice cereal and I wanted to transform them into a fun, Halloween inspired treat my kids and their friends could enjoy. I was going for the classic Frankenstein look, but my daughter actually just calls them “Monster Treats.” She’s 3 so I’m just going to let her have that since she has absolutely no clue who Frankenstein is.
No matter what you decide to call these fun little treats, they are sure to be a crowd favorite this Halloween. I wanted to make them super easy, because that’s pretty much the whole point behind no bake recipes right? No running out to Target to find those little eyeball sprinkles or trying to find pre-made royal icing to glue them on with. Just plain, simple ingredients that the average person would have on hand; I hope you’ll enjoy them and have a Happy Halloween!
