I love the surprise of an upside down cake. It's so exciting to me, the satisfaction of flipping the cake and seeing the beautiful pattern that has been secretly cooking underneath. In the recipe below the apples are layered in a slow cooker and you end up with a cake you never though you could actually make in a slow cooker.
Using a slow cooker liner is the secret. It makes it a breeze to take out of the slow cooker because all you do is lift it out, no mess no fuss. I first make a mixture of melted butter, brown sugar and cinnamon. This is poured right into the slow cooker and spread evenly on the bottom. Then the apple slices are arranged evenly like tiles on a roof. The batter is poured on top of the apples and I line the slow cooker with a few paper towels to absorb any excess moisture.
