Insert a lollipop stick into the center of each marshmallow and set aside. Pour the chocolate or black sprinkles into a small bowl.
In a medium-sized microwaveable bowl, melt the white chocolate chips or candy coating. To melt, cook for 30 seconds, then stir. Continue microwaving in 10-15 second intervals, stirring in between, until melted.
When the candy is completely melted, add the green food coloring and vegetable oil. Stir until the mixture is smooth and your desired shade of green is achieved.
Working one by one, dip the prepared marshmallows into the green candy coating, making sure that the marshmallows are covered at least to the bottom edge of each one, and allow any excess green coating to drip off into the bowl.
Dip the top edge of the coated marshmallow into the sprinkles to create Frankenstein’s hair.
Place a pair of eyes on the front of each marshmallow.
Poke pretzel sticks into the sides of the marshmallows (2 pieces for each) to mimic the bolts on the sides of Frankenstein’s neck.
Continue decorating until all of your marshmallows are complete, placing each one right-side up to dry.
When the candy coating is hardened completely, serve and enjoy.
You can use your preferred candy coating such as almond bark or candy melts instead of white chocolate chips. Just eliminate the vegetable oil, as it’s used to make real white chocolate easier to work with.
Feel free to decrease or increase the amount of liquid food coloring that you add to the white chocolate based on your preferred shade of green.
If needed, use a pair of craft tweezers to precisely place the candy eyes on the marshmallows without getting the coating on your skin or compromising your Frankensteins.
To make drying easier so that the candy coating hardens without making a mess or messing up your Frankensteins, I like to stick the lollipop sticks down into a block of floral foam after decorating each marshmallow. It’s a great way to stabilize the sticks, allow air to circulate all around the coated marshmallows, and let any excess coating drip off while drying.
