Ready for a fun Halloween craft project in the kitchen? Then you are going to love these Marshmallow Frankenstein treats! They are so fun to make with the kids! I love that no matter how they look they still will taste delicious! 

These Marshmallow Frankenstein treats do take some practice. I highly recommend using a pair of tweezers to help place the eyeballs. You do not want to even see my first three attempts at making these without using them. It was a very messy experiment that was a little bit scary. 

Pair these fun Halloween treats with some cupcakes topped with our delicious homemade chocolate frosting and some orange sprinkles for the perfect Halloween treats to share with your friends and family! 

Prep time: 30 minutes

Serves: 24


Marshmallow Frankenstein
  • 1 bag large (not mini) marshmallows
  • Lollipop sticks or bamboo skewers
  • 12 ounces white chocolate chips 
  • 2 tablespoons vegetable oil
  • 10-12 drops of green food coloring (see notes)
  • Brown or black sprinkles (jimmies) 
  • Candy eyes
  • Pretzel sticks, broken into ½-¾  inch pieces


How to Make Marshmallow Frankenstein Treats

  • 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. 

Tips Tricks and FAQs

  • If you would like you can use almond bark or candy melts rather than chocolate chips. If you choose to do this you can omit the vegetable oil. 
  • Do NOT use gel food colors! The tiniest bit of gel will completely change the texture of your white chocolate/candy coating, turning it into a chunky, thick substance that is almost coagulated. Yuck! Liquid food coloring is the way to go.
  • I love these Marshmallow Frankenstein treats to be a nice green color. Feel free to add more or less food coloring based on the desired color that you prefer. 
  • 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.
  • 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.
  • If you want to take the decorating a step further, consider piping a chocolate mouth onto each Frankenstein. Simply melt chocolate chips or chocolate candy coating, spoon it into a zip lock baggie, snip a very small piece off of the end of one corner of the bag. Pipe a straight, horizontal line, then several small, spaced out vertical lines from one end of the horizontal line to the other to create a “stitched” look.


Store these in an airtight container at room temperature for up to 3-4 days.
