Salted Caramel Cold Brew: The Summer Coffee Recipe Everyone Will Ask About

Why Salted Caramel Works With Cold Brew

Cold brew has a natural sweetness and low acidity that makes it one of the most mixer-friendly coffees out there. The richness of caramel matches cold brew's body, and the salt does something important: it suppresses bitterness and makes every other flavor more vivid. Salt in coffee is not a gimmick. It is chemistry.

What You Need

Cold brew: 1 cup coarsely ground coffee + 4 cups cold filtered water (steep 12–24 hrs, strain)

Salted caramel syrup:

• 1 cup granulated sugar
• 1/4 cup water
• 1/2 cup heavy cream (room temperature)
• 2 tablespoons unsalted butter
• 1/2 teaspoon flaky sea salt

To serve: Ice, oat milk or milk of your choice. Start with our cold brew guide

Step 1 — Make the Salted Caramel Syrup

In a small heavy-bottomed saucepan, combine sugar and water over medium heat. Do not stir — swirl the pan occasionally. Cook until the mixture turns a deep amber color (about 8–10 minutes). Watch closely — it goes from amber to burnt in seconds.

Remove from heat and immediately whisk in the heavy cream (it will bubble aggressively — this is normal). Add the butter and whisk until smooth. Add the sea salt. Let cool to room temperature, then transfer to a jar. Keeps in the fridge for up to three weeks.

Step 2 — Build the Drink

Fill a tall glass with ice. Pour in 180ml (6oz) of cold brew concentrate. Add 1–2 tablespoons of salted caramel syrup and stir to combine. Top with a splash of oat milk or cream, depending on how rich you want it. Finish with a pinch of flaky sea salt on top.

Optional but worth it: a small dollop of whipped cream and a drizzle of extra caramel. It looks like something you would pay $9 for at a specialty cafe.

Adjusting the Recipe

Stronger coffee flavor: Use cold brew concentrate at 1:1 ratio with no dilution. Dairy-free: Use coconut cream instead of heavy cream in the syrup, oat milk to serve — the coconut adds a subtle tropical note that works surprisingly well. Frozen version: Blend 180ml cold brew, 2 tablespoons caramel syrup, 1/2 cup milk, and a large handful of ice. You get a cold brew caramel frappe that rivals any chain.

Make a Batch

Double or triple the caramel syrup recipe. It lasts three weeks in the fridge and works on ice cream, in cocktails, over pancakes, and in your morning oatmeal. Making one batch for the week turns your daily cold brew into a 60-second ritual instead of a 10-minute project. This is the summer coffee drink worth perfecting.
