Okay, so I love those drinks, but can't afford $4 for one drink, so I tried out making it with some leftover coffee from the Bible study. It was wonderful.
Christa's Frozen Caramel-Coffee Drink
2 cups coffee
1/2 cup granulated sugar
2 Tablespoons caramel syrup (not the coffee syrups, but actual caramel syrup, caramel topping may also work)
Pour in 2 cups of coffee into your blender. Fill blender almost all the way up with ice, and then fill almost to the top with milk. Blend until smooth. Top with whip cream if desired.
