Copycat Toasted Marshmallow Cold Brew Recipe
How to build the 7 Brew Toasted Marshmallow Cold Brew at home — 5 ingredients, 8 minutes, 344 calories a serving, and roughly $2.40 cheaper per drink than the $5.05 you would pay at the window. This is the recipe I keep coming back to when I am not standing in line.
What you are aiming for — a Toasted Marshmallow Cold Brew off the board. The stand's Medium is 344 calories; this version comes in at 344.
A Toasted Marshmallow Cold Brew is a coldbrew build. Toasted marshmallow is one of the harder flavours to fake, but marshmallow syrup plus a genuinely toasted marshmallow on top gets you there. Toast it with a kitchen torch, not under a grill — a grill cooks it through instead of just the surface.

Ingredients
- 120 ml cold brew concentrate
- 90 ml whole milk
- 2 tbsp toasted marshmallow syrup
- a toasted marshmallow cold foam
- Ice
Equipment
- 1 L jar
- Fine-mesh sieve
- Paper filter
- 16 oz glass
How to make it
- Combine 100 g of coarsely ground coffee with 800 ml of cold filtered water in a jar. Stir once, cap it, and leave it out for 12-16 hours (or in the fridge for 18).
- Strain through a sieve, then again through a paper filter. Do not press or squeeze the grounds — that is what makes home cold brew bitter.
- Fill a 16 oz glass with ice and pour 120 ml of cold brew concentrate over it.
- Stir in 2 tbsp toasted marshmallow syrup. Cold liquid dissolves sugar slowly, so give it a proper 20 seconds.
- Float whole milk on top and let it fall through the drink in ribbons, then add a toasted marshmallow cold foam.
- Cold brew keeps 5 days refrigerated — this is the one to batch on a Sunday.
Tips that actually matter
- Toast with a torch so only the surface caramelises.
- Marshmallow syrup plus vanilla at 1:1 is a fair substitute for a dedicated syrup.
- Cold brew, not hot coffee — heat flattens the marshmallow note.
Variations
- Hot toasted marshmallow latte: espresso and steamed milk.
- Add 1 tsp of chocolate for a s’mores cold brew.
- Graham cracker dusting on the cold foam.
