Monster Marshmallows are easy — a little frosting and sprinkles, a fun straw, and they make a big impression at Halloween time. Try making them with kids for a fun family project!

I’m not so much a cute decorated food person as I am a person who gets a delicious, healthy meal on the table every single night. I’m proud of that!

But Halloween time demands we step up the game a bit. We let loose, we celebrate the macabre, we practice spooky things. We’ll put sweet things on sticks, we’ll swirl some icing, we’ll toss sprinkles here and there with abandon…we’ll amuse and scare ourselves, and have fun doing it, I promise!

The whole trick of these is to just let your freak flag fly. Once you get started, I promise you, you will feel a creative surge and just go to town with all the decorations and sprinkles.

I gave this to my 8-year-old neighbor and he wasn’t allowed to eat it until his parents had the video cam turned on so they could record it. Yes, it’s epic!

Happy Halloween!

 But first, let’s make some Monster Marshmallows. Boo, baby.

Monster Marshmallows

Prep Time: 1 hour

Yield: Makes 12 monster heads

Monster Marshmallows

Marshmallows on a straw become Halloween Monster Marshmallows with a little frosting and some sprinkles -- easy to do and they make a big impression! Try making them with kids for a fun family project!


  • 12 regular marshmallows (not the mini marshmallows, the regular size)
  • 12 paper straws or lollipop sticks
  • 1 tube orange decorator icing (I used Wilton brand)
  • 1 tube black decorator icing (I used Wilton brand)
  • Assorted sprinkles or other crumbled toppings (I used sprinkles from Sweets & Treats, and Wilton)
  • Candy eyeballs, gummy eyeballs and severed finger candy decorations, or any other gross things you like.


  1. Ease the straws into the marshmallows without piercing through the end.
  2. Using an offset spatula or small knife, spread 1-2 teaspoons of the icing over the mallow, covering the sides and top with a thin layer of icing. Immediately apply eyes and any sprinkles you like, and set the marshmallow on the straw, head up, in a tall glass. I sometimes add dry rice kernels to the glass, so the straws have something to grab onto and the mallow heads stay put better.
  3. As soon as you have done 4 or so, place the glass carefully in the refrigerator for 30 minutes or so, so the frosting will harden up a bit. Continue working on the rest. Don't crowd your glass when you finish a mallow. It's always better to give them a lot of "head space." Repeat by putting the second glass of monster heads in the refrigerator to harden. Once they have hardened, they can be removed and kept at room temperature until served.
  4. Makes 12 Monster Marshmallows.'s hard to tell!

Timing: Does it really take an hour to do this? Maybe, maybe not. Once you begin, you'll find your creativity flowing, and you won't want to rush the process. This is more about fun and less about it being an assembly line.

Want to make the Monster Marshmallows with chocolate outside instead of icing?

Monster Marshmallows for Halloween! Recipe on ShockinglyDelicious.comIt’s easy to adapt them to use a chocolate exterior. Instead of the decorator icing, simply place 1/2 cup semi-sweet chocolate chips in a small glass bowl and microwave them until melted, about 30-50 seconds, stopping to stir several times so you can gauge whether they are melted. (Chocolate chips will hold their shape even when melted, unless you stir.) Carry on with the recipe as directed, dipping the mallow head into the melted chocolate or spreading the chocolate over the mallow using an offset spatula. As with the icing, immediately apply the googly eyes and sprinkles.
