Cake in a mug with 4 ingredients? Now that's too good to be true. Mix Nutella, flour, baking powder, and milk in a mug. Bake at 350 degrees for 16-18 minutes for a yummy cake outside and a gooey center.
Nutella Gooey Butter Cake: this was ok-- just ok. the nutella flavor was weak (surprising, since there is a lot in the recipe) and the texture wasn't as gooey and soft as regular butter cake. i don't see us making this one twice.
