Toasted Marshmallow Cold Brew — Coffee Classics

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.

What it should taste like. Marshmallow over cold brew. Should taste toasty and sweet — closer to a campfire smore than a coffee. The toasted note comes from the syrup, not from torching anything.

What you need

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
Method

How to make it

  1. 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).
  2. 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.
  3. Fill a 16 oz glass with ice and pour 120 ml of cold brew concentrate over it.
  4. Stir in 2 tbsp toasted marshmallow syrup. Cold liquid dissolves sugar slowly, so give it a proper 20 seconds.
  5. Float whole milk on top and let it fall through the drink in ribbons, then add a toasted marshmallow cold foam.
  6. Cold brew keeps 5 days refrigerated — this is the one to batch on a Sunday.
Why this works: 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.
Getting it right

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.
Mix it up

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.
