How to Make Roasted Marshmallow Shot Glasses for Winter Parties

Hosting a winter get-together and want to wow your guests without spending hours in the kitchen? There’s a quick, fun way to add warmth and charm to your evening—without needing fancy glassware or elaborate desserts. Imagine handing someone a sweet, gooey, golden-brown marshmallow that doubles as a shot glass. It’s not just a cute gimmick—it’s an interactive, shareable treat that fits right in with cocoa bars, spiked drinks, or even coffee milk pairings.

The trick is simple: lightly roast a marshmallow until the bottom and edges crisp up and it naturally forms a little bowl. That’s it. No special molds, no baking. Just heat, wait, and pour. Read on to learn exactly how to make these adorable edible cups step by step.

What Are Roasted Marshmallow Shot Glasses?

Roasted marshmallow shot glasses are made by toasting a regular marshmallow over a flame or stovetop until the base and sides brown and the inside caves in slightly—forming a natural cup shape. Once cooled, they can hold a small amount of liquid such as hot chocolate, coffee with milk, or even a shot of liquor. They’re edible, Instagram-worthy, and perfect for adding a playful touch to cold-weather gatherings.

Why This Works: The Science of Melting Sugar

When you roast a marshmallow, the heat causes the sugar on the outside to caramelize—a Maillard reaction that browns and firms the surface. The interior, insulated by the outer layer, stays soft a little longer. As the bottom heats, it begins to melt slightly, allowing the marshmallow to sag inward and form a shallow well. That depression becomes your “glass.” Keep the heat controlled, and the structure holds long enough to enjoy a drink or dessert inside.

How to Make Your Own Roasted Marshmallow Cups

You only need two things: marshmallows and a heat source. Here’s the step-by-step from food blogger Cheri Alberts, originally shared on The Watering Mouth and featured by Food Beast:

• Step 1: Skewer the Marshmallow
  Use a fork to hold your marshmallow. Pierce it firmly enough to keep it stable, but don’t push all the way through the bottom—that’s where the cup shape forms.
• Step 2: Toast Over Heat
  Hold the marshmallow over a low flame or stove burner. Keep it about an inch away to avoid burning. Rotate gently for even toasting. Let the bottom and outer edges turn golden brown. For best results, use a second fork to support the base as it melts inward.
• Step 3: Cool and Fill
  Set the roasted marshmallow on a plate to cool for a minute or two. Once stable, pour in your drink—hot chocolate, coffee with milk, or a liqueur. Don’t add the liquid too early or the marshmallow will absorb it and lose its shape.

Mistakes to Avoid

A few common missteps can ruin your marshmallow cup:

• Don’t poke all the way through the bottom—it’s essential for forming the cup.
• Avoid holding the marshmallow too close to the flame, which leads to scorching or sudden collapse.
• Don’t pour your drink into the marshmallow until just before serving, or it will soak through and fall apart.
• Make sure the base is toasted enough to hold shape but not so much that it burns through.

Frequently Asked Questions

How do you get the marshmallow to form a cup shape?

To form a cup, toast the marshmallow over gentle heat until the bottom and outer edges brown. The heat melts the bottom slightly, causing the inside to sag inward and create a natural depression. Supporting the base with a second fork helps guide the shape as it forms.

What can you serve in a roasted marshmallow shot glass?

You can serve hot drinks like cocoa, coffee with milk, or even a small shot of liquor. Avoid cold liquids, which melt the marshmallow faster. For best results, pour the liquid just before serving to prevent sogginess.

How long do roasted marshmallow cups hold their shape?

They’ll hold their shape for a few minutes once cooled, especially if not overloaded with liquid. The warmer and wetter the filling, the quicker they’ll soften and possibly leak. Serve immediately after filling.

Can you prepare these ahead of time?

You can toast the marshmallows ahead, but don’t add the liquid until just before serving. Pre-toasted marshmallows will start to soften within minutes if left unfilled, especially in a warm room.

Is there a way to make them sturdier?

Toasting the base more thoroughly helps, but they’ll always be delicate. Using a second fork to stabilize the bottom during toasting improves the chance of a deeper, more stable cup. Don’t overfill.
