You have likely heard of a diet coke cake (can of coke + chocolate cake mix) or sprite zero cake (can of sprite + white cake mix). Well, in the fall, it’s time for pumpkin spice cake. All you need is a can of pumpkin and a box of spice cake mix. Mix them together and stick them in the oven (just follow the box instructions roughly). Soon, you’ll have an easy, tasty fall treat!
