How to Make Mississippi Mud Brownies

by Alli

When it comes to holiday movies, it’s hard for me to pick a favorite. I like the funny ones, the old traditional ones and the ones that make me cry. What does Mississippi Mud Brownies have to do with movies? Nothing. We just like to eat brownies while we’re watching a good holiday movie! And these are some good brownies.

If I have to choose my favorite movie, it’s a three-way tie between Home Alone, A Christmas Story and It’s a Wonderful Life.

I like how easy brownies are to make. Most of the time, you just mix everything in one big bowl, dump the batter into a pan and bake. This one has a couple extra steps, but it’s all worth it in the end. And, yes, you’ll need your mixer for the frosting.

These Mississippi Mud Brownies have a layer of mini marshmallows on top. Then you quickly pour the frosting over the marshmallows and spread evenly.

I remember when I learned how to spell Mississippi in elementary school. Spelling was always a favorite subject and when my husband and I were first married, we’d have spelling bees to see who could spell the best. Crazy, huh?
