“When I think about coffee, I think about holding a warm mug in the morning, so I loved the idea of a warm mug of coffee infused chocolate cake! My son helped me test out this recipe, and he loved that it was so quick from start to eat. Thanks to Door County Coffee for inspiring a wonderful after-school treat at our house!”
