Nothing screams Autumn quite like caramel and apples. This cake celebrates this age old favorite combination in an incredibly delicious way!
Melt the butter in a medium saucepan over medium heat. Stir constantly until butter is melted and bubbling. Turn off heat for a minute and slowly pour in the cream, milk, and coffee (careful, it will sizzle), After that, add the sugar and salt and return to heat and stir gently until it comes to a boil. Boil for about 7 or 8 minutes until its thick enough to coat the back of a spoon, then remove from heat and stir in vanilla. You should have about 1 1/3 cups.
