Stir together half & half and vanilla syrup to make Sweet Cream.Set aside.
Pour vanilla syrup, cold brew, then ice into a cup.
Add sweet cream.
NOTES
The vanilla syrup and the cold brew can be made ahead of time but keep them separate until the drink is ready to be assembled.
Add as much sweet cream you like to make it creamy and sweet.
I use half & half as a shortcut to making sweet cream, but to make sweet cream just like Starbucks, stir together 6 ounces of heavy cream, 3 ounces of 2% milk, and 1 ounce of vanilla syrup.
