This caramel apple cake is possibly the world’s most phenomenal cake. It smells like autumn and is next to impossible to stop eating. I made this cake for someone’s birthday at work, and when I finished frosting it, I thought – “This thing is huge! It’s a three layer cake with over three cups of frosting… there’s going to be so much leftover…” By 3pm, there were crumbs left. Caramel apple cake is a serious crowd-pleaser.
