Silly, sweet space creatures made from marshmallows, candy coating, and imagination.

Martian Marshmallows were born when my daughter declared her class Halloween party needed aliens. Not ghosts. Not pumpkins. Aliens. I had marshmallows, candy coating, and not much else, but with some candy eyes and a few lollipop sticks, these weird and wonderful treats took shape. They’re simple to make, endlessly creative, and an absolute hit with kids. Inspired by the kind of hands-on fun you see in The Kitchn’s kids’ Halloween projects, these little Martians landed straight into our family tradition.

🟩 Why This Is So Good

No baking, no stress – Just melt, dip, and decorate.
So much personality – Every Martian is unique (and sometimes hilariously weird).
Perfect for parties or classroom treats – Allergy-friendly and easy to transport.
Fun for all ages – Little hands can decorate, no precision required.
Bright, colorful, and irresistibly cute – You’ll get smiles before the first bite.

We made a tray of Martian Marshmallows for my daughter’s school last year, and they were gone before the cupcakes. One kid even gave his Martian a name and took it home instead of eating it. This one’s a memory-maker, and if it’s your first time dipping, check out this candy coating tutorial to get the texture just right.

🟩 Getting Your Ingredients Right

White candy coating is a must – Add food coloring to make your aliens pop.
Shortening helps thin the coating – Easier dipping, smoother finish.
Use paste or gel coloring – Liquid can ruin the texture of melted coating.
Large marshmallows = the perfect alien body
Candy eyes, licorice, and straws = creative gold – Mix and match for crazy characters.

Need a reliable coating? Wilton Candy Melts work well, and you can tint them any Martian hue with gel food coloring.

🟩 Making It Step by Step

Prep your toppings

Before melting anything, set up a toppings station with candy eyes, colored sugars, nonpareils, licorice strips, and sour straws. Cut some into small pieces to use as antennas or arms. Line a baking sheet with wax or parchment paper for cooling.

Melt the candy coating

Place white candy coating and shortening in a microwave-safe bowl. Heat in 30-second intervals, stirring between each, until smooth and fully melted. If using food coloring, stir it in now.

Stick and dip

Insert a lollipop stick into each marshmallow. Dip marshmallows one at a time into the melted coating, letting the excess drip off. While still wet, roll in colored sugar or sprinkle with nonpareils. Press in candy eyes and other decorations before it sets.

Let them set

Place decorated Martian Marshmallows upright on the parchment-lined tray. Let sit at room temp for 15–20 minutes, or pop them in the fridge for 5 to firm up quickly.

🟩 Making Sure It Turns Out

Use shallow bowls for easy dipping
Decorate immediately after dipping – coating hardens fast.
Press toppings gently – too hard and the marshmallow can slide.
Don’t overheat your coating – it should be smooth, not runny or stiff.

The first time I made these, I melted the coating way too hot—and half my marshmallows slid right off the sticks. Now I stir gently and let the coating cool for a minute before dipping. It makes all the difference in keeping those little aliens intact.

🟩 Perfect Serving Ideas

Serve Martian Marshmallows standing up in a foam block or lined up on a tray like an alien army. They’re great for Halloween parties, outer space birthdays, or just a rainy-day craft that ends in sugar. Kids love naming their Martians and comparing who made the weirdest one.

🟩 Making It Different

Go neon with food coloring—lime green, purple, electric blue. Use mini marshmallows for baby aliens or stack two marshmallows on one stick for tall Martians. Add gummy worm “tentacles,” pipe on little mouths with icing, or give them sunglasses with chocolate chips.

🟩 Storage and Leftovers

Store Martian Marshmallows in an airtight container at room temp for up to 3 days. Don’t refrigerate too long or they’ll get sticky. If you’re prepping ahead, make the marshmallows the night before and decorate the day of for best results.

🟩 Tips That Actually Help

Stick marshmallows before melting coating to speed up the process.
Color coating in small batches to offer variety without waste.
Use a foam block or mason jars to hold them upright while setting.

The tip that saved me? Setting up everything before dipping. Once that candy coating starts drying, there’s no time to hunt for candy eyes. Now I have a toppings assembly line—and the decorating becomes the fun part, not the stress part.

Closing Paragraph

Martian Marshmallows are everything a Halloween treat should be—playful, colorful, and fun to make. They’re the kind of snack that sparks creativity, gets laughs, and disappears by the dozen. Once you make them, don’t be surprised if they become a yearly tradition—or if your kids start asking to make aliens in April.

🟩 Frequently Asked Questions

→ Can I make Martian Marshmallows ahead of time?
Yes! Best made 1 day ahead and stored in an airtight container.

→ Do I need to refrigerate them?
No—room temp is best. Refrigeration can make the coating sticky.

→ Can I use chocolate instead of candy coating?
Yes, but it won’t tint as easily if you want colored aliens.

→ What if I don’t have lollipop sticks?
Use toothpicks, straws, or leave them stick-free for bite-sized aliens.

→ How do I keep the marshmallows from falling off?
Let the coating cool slightly before dipping—too hot and the marshmallow melts.

→ Can kids make these?
Definitely! Just handle the hot coating part yourself and let them decorate.
