How to Make Homemade Mississippi Mud Cake in an Oven
Aunt Lou here.
There are three desserts that were always epic to me as a kid, and the list still rings true as an adult. This Homemade Mississippi Mud Cake is one of them. It is a rich dessert that is like a mix of a brownie and a cake. I highly recommend cutting this cake into 16 pieces instead of 12. It is truly rich, but the flavors are just incredible. With it having so many servings in just a 9×13 dish, it makes it a great dessert to take to a potluck.
