Brew the cold coffee. Fill 2 mason jars with ice. Drizzle caramel sauce around the inside of each glass. Add 1 Tbsp of caramel sauce to the glass. Pour brewed coffee over ice and stir.
In another mason jar or glass, combine the half and half, sweetened condensed milk, vanilla, and salt. Using a milk frother, an immersion blender, or whisk, mix together until frothy. Pour over the top and enjoy!
