Roommate and I did this back in December, but I still thought it was worth sharing. It's perfect for a snowy cold day and it's super easy to make: Nutella Chocolate Mug Cakes!
The whipped cream is a must since ours turned out a little dry, but use some chocolate sauce and it's just like lava cake! Recipe here.
Hope everyone is enjoying their lazy or productive Sunday, however you want to spend it!
