It’s a rich, chocolatey cake that is, you guessed it, baked on a sheet pan. It’s a thin cake with a delicious chocolate icing on top. The cake itself has a hint of cinnamon and is very moist. The icing on top is super fudge-y and rich! This cake always makes me think of Thanksgiving and Christmas because that’s when my grandma would make it. It’s so cozy warmed up a little bit with homemade whipped cream on top.
