Apple Cider Caramel

I found the recipe on Cookies and Cups... and knew I wanted to make some to go with the baked doughnuts that are coming up next!

Ingredients
1 cup apple cider
1 cup light brown sugar
½ cup salted butter, cut into cubes and room temperature
¼ cup heavy cream, room temperature
⅛ teaspoon ground cinnamon
¼ teaspoon kosher salt
½ teaspoon vanilla

Instructions

1. On medium-high heat, bring cider to a boil on the stovetop.
2. Boil for ~12 minutes.  It should be reduced to about 1/4 cup.
3. Add in sugar, butter, cream, cinnamon, and salt.  Stir until combined.
4. Boil for 2-3 more minutes.
5. Remove from heat and stir in the vanilla.
6. Cool.
