Apple Sheet Cake With Salted Caramel Frosting

This is my favorite non-chocolate cake. Normally I don’t like a ton of frosting, but I could eat a bowl of this salted caramel with a spoon. (And I’ve done it. SHHHHH!) This recipe isn’t gluten free, but I’ve made it with my gluten-free flour blend and added 1 teaspoon xanthan gum to the dry ingredients. It was still amazing, just a little crumbly.

For Apple Sheet Cake:

Preheat oven to 350 degrees Fahrenheit.  Grease and lightly dust with flour a 11″ x 17″ jelly roll pan and set aside.
