Ingredients You’ll Need

The beauty of this syrup is that the ingredient list is short and easy to keep on hand. Here’s what you’ll need:

• 1 cup mini marshmallows (or chopped regular marshmallows) – mini marshmallows toast evenly, but chopped large ones work too.
• 1 cup granulated sugar – gives the syrup its sweetness and viscosity.
• 1 cup water – helps dissolve the sugar and create a smooth syrup.
• 1 teaspoon vanilla extract – adds depth and richness to the flavor.
• ½ tsp sea salt – can enhance the caramel notes.

That’s it! No corn syrup, no artificial flavors, just marshmallows, sugar, and love.

How to Toast Marshmallows Perfectly

Toasting marshmallows is the secret to this syrup’s rich flavor. You want golden-brown, slightly crispy edges, not burnt sugar. Here are two easy methods:

Oven Method

Stovetop Torch Method

If you have a kitchen torch, you can toast marshmallows directly on a pan. This gives you more control and that signature campfire look. Just hold the flame over the marshmallows until golden brown, rotating as needed.

Either method works beautifully—the key is not to burn them, as burnt marshmallows can make the syrup taste bitter.

Making the Toasted Marshmallow Syrup

Once your marshmallows are perfectly toasted, the syrup itself is a breeze.

Tips for the Perfect Syrup

• Use real marshmallows: Flavored or mini marshmallows work best. Avoid marshmallows with added fillers—they can affect texture.
• Don’t skip toasting: Toasting gives that signature caramelized flavor that makes this syrup stand out.
• Watch your heat: Too high heat can scorch the sugar. Medium heat with constant stirring is key.
• Store in a clean jar: Glass jars with tight lids keep the syrup fresh longer.

Creative Ways to Use Toasted Marshmallow Syrup

This syrup isn’t just for lattes! Here are a few ways to enjoy it:

1. Marshmallow Lattes

Add 1–2 tablespoons of syrup to your favorite latte, stir, and top with whipped cream for a sweet, cozy drink.

2. Hot Chocolate Upgrade

Drizzle into hot chocolate for a campfire-inspired twist. Top with toasted marshmallows for extra indulgence.

3. Milkshakes and Smoothies

Blend a splash into a vanilla or chocolate milkshake. It pairs beautifully with banana or strawberry smoothies too.

4. Dessert Drizzle

Pour over ice cream, pancakes, waffles, or even brownies. The golden toasted flavor pairs well with chocolate, caramel, and nutty desserts.
