Slow Cooker Caramel Apple Pudding Cake

"This Slow Cooker Caramel Apple Pudding Cake is SO simple, loaded with apples and makes its own hot caramel sauce as it cooks. Our new favorite dessert! Let me tell you — I never get it this right on the first try. But this pudding cake is so, so right, and so incredibly delicious. I know I’ve said it before and I say it again — nothing gets me like a warm, gooey dessert with a scoop of vanilla ice cream!"
