Tips for making Rice Krispies Frankenstein Treats

If you can’t find green frosting at the store, you can color your own icing by mixing 30 drops of green food coloring into one cup of a store-bought can of white icing. (Check out this great frosting-to-coloring ratio chart from Food Network if you want to lighten that green up a bit.)
Because you are working with green and black icing, we highly recommend that everyone helping with this one wear an apron or a smock to help avoid accidents and messes that could stain clothes.
You CAN make your own homemade rice krispie treats instead of buying the packaged kind, but homemade tends to be less uniform in size with a bumpy top. That said, homemade could add to these fun snacks’ “monster” quality.
Use the clean kitchen towel to lay the spatula and butter knife down when not in use (helps with cleanup).

Steps to make these fun Halloween Party Treats

Gather your tools and ingredients. Make space in your refrigerator or freezer to hold your pan or two plates level.
Stir the green icing to help soften it.
Place parchment paper on the baking sheet.
Unwrap each treat and lay them out on the sheet.
Using a butter knife or offset spatula, use the green frosting to frost just the tops of each krispie treat. Set aside.
Gently massage the black writing gel with the cap on. Set aside.
Unravel a twizzler so that it separates into segments for the lips (see photos).
With the cutting board and knife (a butter knife should cut the twizzlers fine if you want to pass this task to your child), cut approximately 1-inch lengths of Twizzler segments. Set aside.
Assemble the eyes, if using, or use the black gel to start drawing on two eyes, nose, and hair at the top of each treat. (See photos.)
Add the “lips” last, pressing each 1-inch Twizzler segment under the nose. Don’t stress if something isn’t going on right. He’s a monster, after all.
If there isn’t enough room in your fridge, carefully transfer the “monsters” to two plates so the black icing will set, as it tends to run. Leave for about half an hour undisturbed in the fridge, or 10 minutes in your freezer.
