Make the raspberry cold foam. Add the raspberry cold foam ingredients to a small container or glass and froth with a milk frother for 10-15 seconds or until foamy. Set aside.
Add ice to a tall glass, then pour in the cold brew and vanilla syrup. Stir.
Pour the cold foam over the sweetened cold brew, then drink up!
Notes
Note: use 1 tablespoon chocolate syrup instead of the vanilla syrup for a raspberry chocolate cold brew!
