About a week ago, I shared a recipe for salted caramel sauce. I love it so much that I've sort of been going crazy adding it to everything. First, I added it to my salted caramel cashew bars, and now, I've added it to my apple crisp bars. Please don't feel like you have to make a batch just for this recipe. I hate when I read over a recipe and find out that I have to make three other things before I can make whatever it is that I wanted to make (sorry for the times when I do that!). It just makes me feel stressed out, and I don't want to stress you out. So, if you want to make a batch, great! It's delicious, and if you like caramel, you'll be thrilled with it (and me). If not, these bars a great without it – the salted caramel sauce just adds an extra oomph of deliciousness. One other note, if you like a lot of apple filling, you'll want to double the filling. These bars are about as much crisp as they are apple filling.
