Step 1

In a small pot, melt butter over medium heat.

Step 2

Add heavy cream, brown sugar, and salt.

Step 3

Bring to a low simmer. Once at a simmer, cook for 4 minutes, stirring occasionally, until mixture is thickened (mixture will thicken further as it cools).

Step 4

Remove from heat, stir in vanilla, and transfer caramel to a mason jar or other airtight container for storage.

Step 5

In a small pot, combine 1 tablespoon of the prepared caramel, sugar, and 1/4 cup of the coffee. Heat over medium heat until sugar and caramel completely dissolve and coffee mixture is smooth and uniform in color. Remove from heat and whisk in heavy cream.

Step 6

Add ice to a 16-ounce cup, and pour in remaining 3/4 cup of cold coffee followed by the caramel mixture and stir. Top with whipped cream and drizzle with more caramel sauce if desired. Serve and enjoy!
