Mississippi Mud Cake Recipe

Mississippi Mud Cake is a chocolate lover’s dream of a cake recipe. A rich chocolate cake with marshmallows, and pecans and a delicious frosting.

Y’all know how much I adore my Chocolate Sheet Cake that I shared with y’all a while back? Well, I’ve gone and made it into a Mississippi Mud Cake and let’s just say – YUM!

Heavenly days are they sure enough good!

We hosted a party this weekend for about 65 people and I wanted to be sure to have a dessert option for chocolate lovers. I kept trying to think of just the right dessert to serve and then in the middle of the night the other night, I thought I’d turn that Chocolate Sheet Cake into something else. We all love the recipe and the transformation sounded mighty good to me, so at 2 o’clock in the morning, my mouth started watering just thinking about them.

On Saturday morning as my husband was on the tractor cutting the runway and fields, I got busy in the kitchen. I made six gallons of sweet tea (I started at five but kept having to “taste test” each batch, so I ended up making six!), two gallons of unsweet tea, three gallons of lemonade, prepped all the fixings for a hotdog and hamburger bar, made a scrumptious dip that I can’t wait to share with you this week, and whipped up this cake.

Then, I ran it all up to what we call the Party Barn on the mule to get set up for the party.

About that time, my sweet husband was helping me haul all the teas off of the mule, I asked him to try a bite of the cake for me as we were setting up.  He cut a tiny little wedge off the piece I had for him and then said, “Wow!”

Now, “Wow” can really mean a few different things when said by husbands in case you didn’t already know.

It can mean they are so good that they knock your socks off.

It can mean they taste so horrible there are no other words.

Or, it can even mean that all they can think of is Wow because they are searching for another word so they don’t hurt your feelings.

So, in the short of it, I never know how to take the word, “Wow!”

So I pushed.

I prodded.

I just came right out and asked him, “Does that mean you like them?”

A girl’s just gotta know that sort of thing before she serves something to 65 people, you know!

And then he kissed me causing even more confusion.

And finally, he picked up the rest of the piece and popped it into his mouth and gave me a little wink.

I think he just likes messing with me.


Here’s how I make them.

    Can I assume that 1 stick of butter is 1/4 of a pound – or a half cup? Up here, it is just usually sold as a pound block.
