Before You Start: The Basics

How to Make a Toasted Marshmallow Brown Sugar Latte (Step by Step)

Step 1: Toast the marshmallows

Spread the mini marshmallows on a small baking tray. Toast with a kitchen torch or under the broiler until golden brown.

Step 2: Make the syrup

Add the toasted marshmallows, white sugar, and water to a small pan. Simmer on low for 5 minutes, stirring often, until the marshmallows melt. Strain and let it cool.

Step 3: Add the brown sugar and coffee

Add the brown sugar and 2 tablespoons of syrup to a tall glass. Pour in the hot strong coffee and stir until the sugar dissolves.

Step 4: Add ice and milk

Fill the glass with ice. Pour the cold milk over the top and stir lightly.

Step 5: Top with marshmallow cold foam

Froth the 1/4 cup cold milk with 1 tablespoon of syrup until thick and fluffy. Spoon it over the latte. Add a pinch of brown sugar and a few toasted marshmallow bits.

Tips for the Best Latte

• Strain the syrup so it stays smooth.
• Add more syrup, 1 teaspoon at a time, if you want it sweeter.
• Froth the cold foam for about 20 seconds with a handheld frother. Do not over-froth.
• Use whole milk for the creamiest foam.

Variations

• Oat milk: Use oat milk for a dairy-free latte.
• Hot version: Skip the ice and use steamed milk instead.
• Less sweet: Use 1 tablespoon of syrup and skip the brown sugar.
• Extra cozy: Add a pinch of cinnamon to the cold foam.
• Cold brew: Use 1/2 cup cold brew instead of hot coffee.

Storage

Keep the extra syrup in a clean, closed jar in the fridge for up to 2 weeks. Shake or stir before using. Make the latte fresh for the best taste.
