The BEST Mississippi Mud Cake
This is my favorite dessert of all time. My mother has been making this since I could walk and it never disappoints. The icing and marshmallow and chocolate layers melt in your mouth. This recipe does NOT disappoint.
cocoa (I use 100% pure cocoa)
Melt butter in the microwave.
Whisk in cocoa, sugar, eggs, flour, salt and vanilla. Spray a 9 x 13 pan with cooking spray. Add batter to the baking pan.
Bake in preheated 350 degree oven for 20-25 minutes if using jelly roll pan or about 30 to 35 if using 9 x 13 pan checking for doneness as ovens vary.
Remove from oven and spread marshmallows on top while the cake is still hot. Add this frosting over melted marshmallow.
Beat all the frosting ingredients together with mixer. Spread over the marshmallows on top of the cake.
Let cake cool completely before serving.
Note: I keep this cake in the refrigerator
