How to Make Homemade Mississipi Mud Cake

I love when chef's use classic recipes as inspiration for something bigger and better. For example, this Mississippi Mud Cake is inspired by the flavors and makeup of a traditional Mississippi Mud Pie. A super moist chocolatey cake, a decadent chocolate frosting, and gooey melted marshmallows. If you like chocolate - this is a good recipe for you.

I might be the only person in the history of the world that has ever been grounded from baking. That's right. When I was a teen, it wasn't the computer, or the phone or the tv that got taken away. For me, it was the unsalted butter.
