It's an upside down cake, cooked and baked in a heavy skillet. I made this cake more than a week ago, of course, when I had the urgency to finish up the green apples in the fridge that occupied my fridge drawer for a long while. It's a recipe from the Pioneer Woman website, using a skillet to cook the caramel and apple first, prior to putting the dough and then bake the cake in the oven.
It's another recipe that's reasonably easy to do and tastes yummy too. You could have vanilla ice cream with it, but I like it just like that.
