This cake is UGLY. Like U-G-L-Y-it-ain't-got-no-alibi UGLY. I just don't want you to be surprised. But spoon it up into a bowl and top with some ice cream and trust me, you won't care. In addition to be delicious, it's drop-dead easy!
Put pumpkin, spice cake mix, and butter into your slow cooker in that order, kind of making sure each layer is level. Cook on high for 2 hours before opening to thoroughly mix the ingredients. Cook on high for another hour and serve in bowls topped with ice cream.
