Adorable Ghost Cupcakes: Easy Marshmallow Fondant Recipe

“Mom, can we make the ghost ones again?” My six-year-old asked this last October, and honestly, I hadn’t thought about those cupcakes since the year before. I remember the first time I attempted them. I was scrolling through Pinterest at 11 PM, convinced I could pull off something cute for her class party. The original recipe I found called for rolling out store-bought fondant, cutting ghost shapes, and hoping for the best. It looked simple enough. But when I tried it, the fondant cracked, the shapes looked like sad blobs, and I ended up frosting the cupcakes with a butter knife while muttering things I shouldn’t say around kids.

That failure stuck with me. Not because it was a disaster—though it was—but because the idea was so good. Little ghost cupcakes with sweet faces, sitting on a tray, making everyone smile. I wanted that. So I went back to the drawing board. Instead of fighting with store-bought fondant, I made my own marshmallow fondant from scratch. Total game changer. It’s softer, sweeter, and way more forgiving. These adorable ghost cupcakes with marshmallow fondant toppers became the thing I actually look forward to making every Halloween season. They’re not perfect, and that’s exactly the point. A slightly lopsided ghost with crooked eyes is a hundred times more charming than a factory-stamped one. Trust me on that.

Why You’ll Love This Recipe

Let me tell you why these little ghosts have earned a permanent spot in my fall baking rotation. First off, they’re genuinely easy. I’m not a trained pastry chef—I’m a mom who bakes in a kitchen that always has a layer of flour on the floor. If I can pull these off, you absolutely can.

• Quick & Easy : The whole process, from mixing the cupcakes to finishing the ghosts, takes about 90 minutes. Most of that is hands-off baking and chilling time.
• Simple Ingredients : You probably have everything for the cupcakes in your pantry right now. The marshmallow fondant uses just marshmallows, powdered sugar, and shortening. No fancy cake decorating supplies required.
• Perfect for Halloween Parties : These are the star of any classroom celebration, office potluck, or neighborhood gathering. Kids go nuts for them, and adults can’t help but smile.
• Crowd-Pleaser : I’ve brought these to three different Halloween events, and they disappear faster than the candy bowl on November 1st.
• Unbelievably Delicious : The marshmallow fondant tastes like a soft marshmallow—not like the bland, waxy stuff from the store. Paired with a moist vanilla cupcake, it’s pure comfort.

What really sets this recipe apart is the fondant. Most people hate working with fondant because it’s stiff and cracks easily. But homemade marshmallow fondant is a different animal. It stretches, it bends, and it tastes good. You can roll it thin, cut it without tearing, and shape it into the cutest little ghosts you’ve ever seen. And here’s the thing—these aren’t just for Halloween. I’ve made them for a “spooky” themed birthday party in July and for a Day of the Dead celebration. They’re versatile in the best way.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples, so you might not even need a grocery run.

For the Vanilla Cupcakes

• 1 ½ cups all-purpose flour (I use Gold Medal, it gives a nice tender crumb)
• 1 cup granulated sugar
• ½ cup unsalted butter, softened (make sure it’s room temp, it makes a difference)
• 2 large eggs, room temperature
• 1 ½ teaspoons baking powder
• ½ teaspoon salt
• ½ cup whole milk (you can use 2%, but whole milk makes them richer)
• 1 teaspoon vanilla extract (pure, not imitation, if you can swing it)

For the Marshmallow Fondant Ghosts

• 10 ounces mini marshmallows (one standard bag, Jet-Puffed works great)
• 2-3 cups powdered sugar, sifted (plus extra for dusting)
• 2 tablespoons water
• 2 tablespoons vegetable shortening (Crisco is my go-to)
• Black gel food coloring (for the eyes and mouth, or use black decorating icing in a tube)
• Optional: edible glitter dust or luster powder for a shimmer effect

For the Buttercream Frosting

• ½ cup unsalted butter, softened
• 2 cups powdered sugar, sifted
• 2 tablespoons heavy cream (or milk, in a pinch)
• 1 teaspoon vanilla extract
• Pinch of salt

One thing I learned the hard way—don’t skip sifting the powdered sugar for the fondant. Lumps in the sugar create lumps in the dough, and then you’re picking out little white clumps while your ghost looks like it has acne. Not cute. Also, if you’re dairy-free, you can swap the butter for a good vegan butter stick (I like Earth Balance) and use oat milk. The cupcakes will still be fluffy.

Equipment Needed

You don’t need a professional bakery setup for these. Here’s what I use:

• Standard 12-cup muffin tin (non-stick is nice, but any will do)
• Paper cupcake liners (white or orange for Halloween vibes)
• Electric hand mixer or stand mixer (you can mix by hand, but the buttercream will thank you for the elbow grease)
• Large mixing bowls (at least two)
• Rolling pin (I use a wooden one, but silicone works too)
• Small ghost-shaped cookie cutter (about 2-3 inches tall, I found mine at a craft store for $3)
• Parchment paper (for rolling the fondant and lining the baking sheet)
• Small offset spatula (for frosting, though a butter knife works in a pinch)
• Toothpick or small paintbrush (for applying the gel coloring for eyes)
• Microwave-safe bowl (for melting marshmallows)

If you don’t have a ghost cutter, don’t panic. You can freehand the shape with a paring knife, or use a small round cutter and pinch the top into a point. I’ve done both, and honestly, the freehand ones sometimes look cuter because they’re all a little different.

Preparation Method

Step 1: Make the Cupcakes

Preheat your oven to 350°F (175°C). Line your muffin tin with paper liners. In a medium bowl, whisk together the flour, baking powder, and salt. Set aside. In a large bowl, beat the softened butter and sugar together until light and fluffy—about 3 minutes with an electric mixer. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract. Now, alternate adding the flour mixture and the milk, starting and ending with the flour. Mix until just combined, scraping down the sides. Don’t overmix, or the cupcakes will be tough. Divide the batter evenly among the 12 liners, filling each about two-thirds full. Bake for 18-20 minutes, until a toothpick inserted in the center comes out clean. Let them cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.

Step 2: Make the Marshmallow Fondant

While the cupcakes cool, make the fondant. Place the mini marshmallows and 2 tablespoons of water in a large microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until the marshmallows are fully melted and smooth—this usually takes about 90 seconds total. Add the vegetable shortening and stir until it melts completely. Now, start adding the sifted powdered sugar, one cup at a time, stirring with a wooden spoon. It will get stiff. When it becomes too hard to stir, turn it out onto a surface dusted with powdered sugar and knead it by hand. Keep adding powdered sugar until the dough is smooth, soft, and no longer sticky. This takes about 5-8 minutes of kneading. Wrap the fondant tightly in plastic wrap and let it rest at room temperature for at least 30 minutes.

Step 3: Make the Buttercream Frosting

In a large bowl, beat the softened butter until creamy. Add the sifted powdered sugar, one cup at a time, beating on low speed. Add the heavy cream, vanilla extract, and salt. Increase speed to medium-high and beat for 2-3 minutes, until light and fluffy. If the frosting is too thick, add a splash more cream. If it’s too thin, add a bit more powdered sugar. Set aside.

Step 4: Shape the Ghosts

Lightly dust your work surface with powdered sugar. Roll out the marshmallow fondant to about ¼-inch thickness. Use your ghost-shaped cutter to press out as many ghosts as you can. Gather the scraps, re-roll, and cut more. You should get about 12 ghosts from one batch of fondant. Place the ghosts on a parchment-lined baking sheet. Now, for the faces. Dip a toothpick into the black gel food coloring and carefully dot two eyes and a mouth onto each ghost. Don’t overthink it—tiny little circles and an “O” shape for the mouth is all you need. Let the ghosts dry and firm up for about 15 minutes while you frost the cupcakes.

Step 5: Assemble

Once the cupcakes are completely cool, pipe or spread a generous swirl of buttercream on top of each one. Gently press a marshmallow ghost onto the frosting. The frosting acts like glue, so they’ll stay put. If you want, you can dust the ghosts with a little edible glitter for a magical, moonlight shimmer. I did this for a Halloween party last year, and people thought I bought them from a bakery. I didn’t correct them.

Cooking Tips & Techniques

Here are the things I wish someone had told me before I started making these. First, when you’re melting the marshmallows, don’t walk away. They can go from fluffy to scorched in about 15 seconds. I learned this the hard way when I had to start over because my marshmallows turned into a hard, brown brick. Second, kneading the fondant is a workout. Your hands will get tired. That’s normal. Just keep going until it feels like soft play-dough. If it’s too sticky, add more powdered sugar. If it’s too dry, add a tiny drop of water.

Another thing—when you’re cutting the ghosts, dip the cutter in powdered sugar between each cut. This prevents sticking and gives you clean edges. And don’t stress if some ghosts look a little wonky. I once made a ghost that looked like it was melting, and my niece called it “the sleepy ghost” and claimed it as her favorite. Imperfections add character.

For the buttercream, make sure your butter is truly softened. If it’s too cold, the frosting will be lumpy. If it’s too warm, it will be soupy. I leave my butter on the counter for about an hour before I start baking. And if you’re making these ahead of time, store the unfrosted cupcakes in an airtight container, the fondant ghosts in a single layer on parchment, and the buttercream in the fridge. Assemble on the day you serve them.

Variations & Adaptations

One of my favorite things about this recipe is how easy it is to change up. Here are some variations I’ve tried and loved:

• Gluten-Free Version : Swap the all-purpose flour for a good gluten-free baking blend (I like King Arthur’s). The texture is slightly more crumbly, but still delicious.
• Chocolate Ghost Cupcakes : Replace ¼ cup of the flour with unsweetened cocoa powder. The dark chocolate ghosts are extra spooky and rich.
• Pumpkin Spice Ghosts : Add 1 teaspoon of pumpkin pie spice to the cupcake batter and use a cream cheese frosting instead of buttercream. It’s like fall in a cupcake.
• Vegan Option : Use flax eggs (1 tablespoon ground flaxseed mixed with 3 tablespoons water per egg), plant-based butter, and oat milk. The fondant is already accidentally vegan since it’s made from marshmallows (check the label, some brands use gelatin).
• Mini Ghosts : Use a mini muffin tin and a smaller ghost cutter for bite-sized treats. Perfect for parties where people want to try a little of everything.

I also tried a version where I dyed the fondant a pale lavender by kneading in a drop of purple gel coloring. The ghosts looked magical, like they were glowing. My daughter called them “twilight ghosts,” and we ate all twelve in one sitting.

Serving & Storage Suggestions

These cupcakes are best served at room temperature. The buttercream softens, the fondant stays tender, and everything just tastes better. If you’re serving them at a party, arrange them on a platter with some fake cobwebs and plastic spiders for a fun presentation. I like to put them on a black cake stand—it makes the white ghosts really pop.

For storage, keep any leftovers in an airtight container at room temperature for up to 2 days. After that, the fondant can get a little sticky. If you need to store them longer, refrigerate them in a sealed container for up to 5 days. Just let them come to room temperature before serving. I don’t recommend freezing the assembled cupcakes because the fondant can get weepy when thawed. But you can freeze the unfrosted cupcakes for up to 3 months. Just wrap them tightly in plastic wrap and then foil.

One thing I’ve noticed—the flavors actually get better after a day. The marshmallow fondant absorbs a tiny bit of moisture from the frosting, and the whole thing becomes more cohesive. If you can resist eating them all on day one, you’ll be rewarded on day two.

Nutritional Information & Benefits

Let’s be real—these are a treat, not a health food. But here’s the estimated breakdown for one cupcake with buttercream and a fondant ghost:

• Calories: 380
• Fat: 16g
• Carbohydrates: 58g
• Protein: 4g
• Sugar: 42g
• Sodium: 180mg

That said, there are a few bright spots. The marshmallow fondant is lower in fat than traditional buttercream-heavy decorations. And if you use a good-quality vanilla extract, you’re getting a small amount of antioxidants from the vanilla beans. I also like to tell myself that the butter in the frosting has vitamin A, and the eggs in the cupcakes have protein. Is that a stretch? Absolutely. But it makes me feel better about having two.

For anyone with dietary restrictions, this recipe can be adapted for gluten-free or dairy-free needs. Just be aware that the sugar content is still high, so these are best enjoyed as an occasional indulgence—like on Halloween, or a Tuesday when you just need a little joy.

Conclusion

I’ve made these adorable ghost cupcakes for four Halloweens in a row now, and they never get old. There’s something about seeing a tray of little marshmallow ghosts with their crooked eyes and tiny mouths that makes people genuinely happy. It’s not about perfection—it’s about the fun of making something cute and sharing it with the people you love.

I hope you give these a try. Don’t worry if your ghosts look a little lopsided or your frosting swirl isn’t magazine-worthy. That’s part of the charm. If you make them, I’d love to hear how they turned out. Drop a comment below or tag me in your photos. And if you come up with a fun variation—like zombie ghosts or vampire bats—please share that too. Happy Halloween, and happy baking!

Frequently Asked Questions

Can I use store-bought fondant instead of making marshmallow fondant?

You can, but I really recommend making the marshmallow version. Store-bought fondant often tastes bland and has a weird, waxy texture. Homemade marshmallow fondant is softer, sweeter, and way easier to work with. Plus, it’s cheaper to make yourself.

My fondant is too sticky. What do I do?

Knead in more sifted powdered sugar, one tablespoon at a time, until it reaches a smooth, non-sticky consistency. If it’s still sticky after adding sugar, let it rest for 15 minutes. Sometimes the moisture just needs to redistribute.

Can I make these cupcakes ahead of time for a party?

Yes! Bake the cupcakes up to 2 days in advance and store them in an airtight container. Make the fondant ghosts up to 3 days ahead and keep them in a single layer on parchment paper at room temperature. Make the frosting the day of. Assemble everything a few hours before serving.

My ghosts keep cracking when I roll out the fondant. What’s wrong?

Your fondant might be too dry. Add a tiny drop of water and knead it in until the dough becomes pliable again. Also, make sure your work surface is lightly dusted with powdered sugar, not flour. Flour can dry out the fondant and cause cracking.

Can I use a different frosting instead of buttercream?

Absolutely. Cream cheese frosting is amazing with these, especially if you’re doing a pumpkin spice version. You can also use a simple glaze made from powdered sugar and milk, or even a dollop of whipped cream. Just keep in mind that the frosting acts as glue for the fondant ghost, so it needs to be thick enough to hold it in place.
