Ingredients

Toasted marshmallow syrup
Store-bought or homemade (made by dissolving toasted marshmallows in a simple syrup of sugar and water)
2 shots of espresso (or ½ cup strongly brewed coffee)
6 to 8 oz of milk (whole milk or your preferred milk alternative)
Ice (for an iced version)
Optional toppings:
Cold foam made from heavy cream, milk, and syrup
Toasted marshmallows or marshmallow fluff

Directions

Prepare your espresso or brew a strong coffee. If using instant espresso, follow the package instructions to create concentrated coffee.
Pour 1 to 2 ounces of toasted marshmallow syrup into your cup or glass. Adjust the amount based on how sweet you like your latte.
For a hot latte:

Steam or heat your milk until hot but not boiling.
Add the espresso to the cup and stir in the milk.
Top with milk foam and an optional toasted marshmallow garnish.

For an iced latte:

Fill a tall glass with ice.
Pour in the espresso, followed by the milk.
Give everything a gentle stir, then top with cold foam if you like.

Tips & Variations

Chocolate twist: Rim your mug or glass with chocolate syrup and crushed graham crackers for an extra s’mores effect.
Make it lighter: If you prefer fewer calories, use a lighter milk or a sugar free syrup.
Adjust the sweetness: Start with a smaller amount of syrup, then add more if desired. The toasted marshmallow flavor can be intense, so a little goes a long way.
Espresso swap: You can always substitute 2 shots of espresso with ½ cup of strong brewed coffee.

Frequently Asked Questions (FAQs)

Can you store toasted marshmallow syrup in the fridge?
Yes. Most homemade syrup can last about one to three weeks when stored in an airtight container. Store-bought versions also come with their own recommended shelf life.
Can you make this latte without an espresso machine?
Absolutely. Brew a very strong cup of coffee or use instant espresso to replicate those bold flavors.
How can I make this recipe healthier?
Switch to low-fat or plant-based milk and opt for a sugar free or reduced-sugar toasted marshmallow syrup. You can also skip the whipped toppings to cut down on calories.
Can I use flavor variations besides marshmallow?
Definitely. For a different holiday twist, consider trying a peppermint or pumpkin spice alternative. However, toasted marshmallow provides that distinct campfire-like sweetness.
Why do I need to toast the marshmallows for the syrup?
Toasting the marshmallows gives the syrup its signature hint of smokiness. This flavor sets it apart from just plain sweet syrup and captures the essence of roasting marshmallows over a fire.
