How to Create Frankenstein Rice Krispie Treats

Step 1: Make the Rice Cereal Treats

First, make some rice krispie treats. Press the treats firmly into the baking pan to ensure they are nice and packed and allow them to cool.

Step 2: Cut Out Rectangles

Remove the treats from the pan and cut them into rectangles. I trimmed off the curved edges first to get nice straight lines.

Step 3: Frost the Rectangles with Green Frosting

Frost each rectangle with a thick layer of frosting and place in the fridge for 15 minutes to firm. This makes decorating easier.

Step 4: Create Fun Frankenstein Faces

Create the hair and mouth with black decorating frosting. Add eye candies, sprinkles, and any other decoration you would like.

For the studs on the side of the face, cut up small squares of the graham crackers and push them into the side of the frosting. Get creative!

How to Make Thick Buttercream Frosting

This is my go-to buttercream frosting for cookies, cakes, and treats when I need a substantial frosting that will hold up well and create a thick layer. I learned this recipe from The Icing Artist who has awesome tutorials and recipes.

Place the butter and shortening in a stand mixer and cream together on medium speed. Mix in vanilla and salt.
Begin to add powdered sugar one cup at a time, mixing on low speed until combined then med-high speed for a minute or so each time. After each cup addition, add a tablespoon of cold water to get your desired consistency.
Add gel food coloring to the desired color.

Expert Tips for Decorated Rice Krispie Treats

To make the candy eyes look bloodshot, use an edible marker to draw on them.
Packaged decorating icing is an inexpensive and easy way to decorate without making another frosting. It dries shiny and thick which is perfect for decoration. Black is also a hard color to achieve when making your own frosting, so why not let someone else do it?
A wet finger can smooth out imperfections in the frosting.
I used different sprinkles I had on hand to make eyebrows and noses on some of the Frankensteins. I thought it was fun to make different faces and expressions.
To get a nice, packed rice cereal treat, spray your hands with non-stick spray and press firmly all over the pan. Be careful, the mixture is hot at first so wait for it to cool slightly.
These treats are best at room temperature, but I would suggest storing them in the fridge until you are ready to serve them. Allow them to sit at room temperature for about 10 minutes to allow them to soften before enjoying them.
