Make the best Mississippi mud cake with this highly reviewed marshmallow fluff that Amazon reviewers swear by!

This recipe was handed down from my mother.

Right now we are on vacation and around here we are taking each day as it comes. We are relaxing and baking and napping and wrapping and just soaking in every minute of the simple joy of putting together a puzzle.

It’s the little things.

I just baked my mother’s secret recipe for Mississippi Mud Cake and life is a little sweeter here now.

If you liked the other family recipes I've shared, you will LOVE this one.

Here’s a recipe to make your day a little brighter.

Mississippi Mud Cake

I know it says you are supposed to let the cake cool completely.

But sometimes?

This happens.

I walked around the corner and the corner of the Mississippi Mud Cake was history.

If you only make one new dessert this holiday, let this be the one. 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—especially served with these copper mules and these cute white baking dishes which are perfect to gift the cake to someone or even bring it to the next party. They match my kitchen perfectly.
