Heat 1 Tablespoon butter in a small skillet over medium heat.

Add sliced apples and saute 5 minutes or until apples soften and begin to brown. Remove from heat.

Meanwhile, in a small saucepan, combine brown sugar, cornstarch, water, half & half, and kosher salt.

Cook, stirring, over medium-high heat until mixture begins to bubble and thicken.

Cook 2-3 minutes more, until mixture is a rich caramel color. Remove from heat.

Stir in 1 Tablespoon butter and 1/2 teaspoon vanilla.

Pour over apples and top with chopped peanuts.
