Add apples and saute 5 minutes or until apples soften and begin to brown. Remove from heat.
Meanwhile, in a small saucepan, combine Truvia® Brown Sugar Blend, corn starch, 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.

Pour over apples and top with chopped peanuts.
