There’s something magical about the crackling warmth of a campfire, the smoky air, and the simple joy of roasting marshmallows until they’re golden brown—or delightfully charred. It’s a nostalgic flavor that instantly transports you back to cozy nights with friends and family, sticky fingers, and the satisfying crunch of a perfectly toasted treat. Now imagine all that comforting, toasty goodness swirled into a cup of creamy coffee. That’s exactly what a toasted marshmallow latte delivers.

This latte has a toasted marshmallow syrup that dissolves into creamy milk with an espresso boost. It’s indulgent, cozy, and just the right amount of sweet, plus it’s super easy to make!

Here’s how to make this comforting toasted marshmallow latte at home!

What’s in a Toasted Marshmallow Latte?

A toasted marshmallow latte is made of milk, espresso, ice, and toasted marshmallow syrup, plus a toasted marshmallow on top as an extra garnish. You can enjoy it hot or cold, and it’s delicious both ways.

You can use your favorite milk or dairy-free or vegan milk, as well as your choice of coffee. The beauty of making drinks at home is you can customize it to your preferred taste. My personal preference is making this iced with whole milk!

What Does a Toasted Marshmallow Latte Taste Like?

This drink mimics the experience of eating a toasted marshmallow and washing it down with a cup of creamy coffee. The toasted marshmallow syrup adds a rich, slightly caramelized sweetness balanced by the smoky undertones from toasting, which pairs perfectly with the smokiness of roasted coffee beans.

Plus, both the toasted marshmallows and coffee have a slight bitterness, which helps balance the syrup’s sweetness, making it even more addicting. You’ll love this drink if you love roasty, toasty, and smokey flavors.

How to Toast Marshmallows at Home

You don’t need a campfire to roast marshmallows! All you need is a fire source, heatproof skewers or chopsticks, and your favorite marshmallows. Toasting marshmallows at home is easy and super fun! It’s mesmerizing watching a white marshmallow turn golden brown.

There are a few ways to get that perfect golden brown (or charred, if that’s your thing):

• Gas stove burner: If you have a gas stove, you can skewer the marshmallows on a (heatproof) stick or skewer and carefully roast them over the middle of the burner (hottest part). Hold them close enough to toast but not so close that they catch on fire and rotate constantly. It’ll burn if you let your marshmallow roast on one side too long!
• Butane kitchen torch: Another great option is using a kitchen torch. Torches give you precise control over the level of toastiness and are fantastic for achieving that perfect golden-brown hue. Plus, it’ll save your fingers from constantly turning the marshmallow skewer.
• Lighter: A lighter can work in a pinch without fancy tools or a stovetop burner. Keep the flame underneath the marshmallow while you rotate it for an even toast. This method may take a while… but it works!

Best Marshmallows to Use

Large marshmallows are the best for this drink! They’re large enough to toast on a skewer easily, and you don’t need many to make this yummy drink. Any store-bought marshmallow works perfectly, although you can also try making your own.

For better flavor, go for an artisanal or higher-quality marshmallow. They often have a creamier texture and are made with better ingredients, which can elevate your latte.

You can also use mini marshmallows and easily toast them in a baking dish and broil them until golden brown. Because the mini marshmallows have more surface area than a large marshmallow for toasting, I think you’ll get more of the toasted flavor in the syrup!

Vegan marshmallows are also widely available now, so everyone can enjoy this toasty treat.

What Does Toasted Marshmallow Syrup Taste Like?

Toasted marshmallow syrup is sweet, smoky, and slightly caramelized, with a rich yet light flavor, blending the warmth of vanilla with the light smokiness of a perfectly toasted marshmallow.

The syrup is literally melted down toasted marshmallows, so it tastes very close to, if not exactly like, the actual thing. When you make it, it also has an interesting viscous texture that makes it fun to use!

In coffee, it acts as a sweetener and gives it a nice smoky flavor.

How to Make Toasted Marshmallow Syrup

Making toasted marshmallow syrup at home is so easy.

Start by toasting marshmallows until golden brown, then add them to a small pot with water and melt them over low heat. As they heat up, the marshmallows will expand, so use a slightly bigger pot than you think you’ll need.

Let the mixture simmer for a few minutes until the marshmallows have dissolved, and constantly stir to mix the marshmallows into the water. Then remove it from heat and stir in a splash of vanilla extract for extra flavor.

You can optionally strain the syrup to remove any marshmallow chunks, and you’ve got yourself a homemade toasted marshmallow syrup that’s perfect for lattes or even drizzling over desserts.

How to Make a Toasted Marshmallow Latte

Here’s what you’ll need to make a toasted marshmallow latte:

• A fire source
• Marshmallows
• Water
• Milk
• Ice
• Espresso

Toasted Marshmallow Latte Recipe

1. Brew espresso. Brew espresso or a strong coffee equivalent using your favorite method. You can even use espresso instant powder or coffee concentrate.
2. Toast marshmallows. Using whatever method available, toast your marshmallows until golden brown all around. Be careful about using too much heat or burning your marshmallows.
3. Make marshmallow syrup. Dissolve toasted marshmallows with water in a small saucepan on low to medium heat. Once the mixture boils, simmer the syrup until the marshmallows melt. Stir constantly to incorporate it well. Let cool before transferring to an airtight container or use, and store in the fridge for 2 weeks.
4. Assemble drink. Add marshmallow syrup and milk to a cup and stir until dissolved. Add ice and top with your espresso. Optional: garnish with a toasted marshmallow!
5. Mix and enjoy!

Can Marshmallow Fluff be Toasted?

Yes, marshmallow fluff can be toasted, but not traditionally like an actual marshmallow.

To toast marshmallow fluff, spread it onto a heatproof surface and then use a kitchen torch to toast it. It’ll brown quickly, so work fast while moving your touch around the tray evenly.

You can also add the fluff to a baking tray and broil it in the oven until the top is golden brown. Watch it closely to prevent burning!

Once you have your toasted marshmallow fluff, scoop it into a saucepan to make the toasted marshmallow syrup!

Additionally, fluff won’t hold its shape like regular marshmallows, so it’s best used as a topping rather than a garnish. It’s deliciously gooey and adds a fun texture to your latte.

Tips

• Burnt Marshmallow Flavor: Love that charred marshmallow taste? Toast your marshmallows until they’re dark, and add them to your syrup for extra smoky flavor.
• Expanding Marshmallows: Be careful when toasting marshmallows—they expand when heated, so don’t let them touch open flames for too long. They’ll also get soft and start sliding off the skewer.
• Add Vanilla Extract: A splash of vanilla in your syrup or drink enhances the toasted marshmallow flavor!
• Make It Vegan: Use plant-based milk and vegan marshmallows to create a dairy-free version that’s just as delicious.
• Gift Marshmallow Syrup: Homemade toasted marshmallow syrup makes a thoughtful, unique gift for coffee lovers! Package it in a cute jar with a label, and you’re good to go.
