But before you can lick the spoon, check out these ingredients.

  • xanthan gum-- omit if your all-purpose flour contains this or guar gum
  • cocoa powder
  • large eggs

  • vanilla extract-- we use the McCormick brand
  • mini marshmallows-- the Dandies marshmallows do not contain any gluten or dairy; however, they do contain soy. Mini marshmallows can also be omitted and you can enjoy this cake more like a mini Texas sheet cake.

frequently asked questions

what is the difference between chocolate cake and Mississippi mud cake

A chocolate Mississippi Mud Cake recipe has a dense cake that cuts easily and does not crumb.

There is also a stronger chocolate flavor in the mud cake versus a traditional chocolate cake.

Needless to say-- this cake is all about the chocolate flavor.

can I use a chocolate cake mix

Yes, if you are short on time you can also use a gluten and dairy free chocolate cake box mix as the bottom layer.

Follow the box mix instructions for baking a 9x13-inch cake.

can this be prepared ahead of time

Not only is this gluten free and dairy free cake absolutely delicious, but it can also be prepared a day ahead of time with no troubles.

After frosting the cake and marshmallows, cover and set in the refrigerator.

what marshmallows are safe to use

The Dandies marshmallows are known as a safe gluten and dairy free brand.

However, this brand contains soy.

And if you just hate marshmallows or cannot find safe ones, leave them out and frost the cake with our delicious chocolate frosting.

how do I store leftovers

Cover and store in the refrigerator up to 5 days. Just before serving we like to allow the cake to sit on the countertop for 15-20 minutes.

Just saw the recipe. Already made a cake. Can I melt marshmallows and add? What’s the best way to do that? Thanks

Yes, if the cake has completely cooled we just topping with marshmallows then popping it back into the oven for at 200 degrees F for just a minute to get the marshmallows a little melty. Then continue with the rest of the recipe. Enjoy, Jill
