Mississippi Mud Brownies

I am totally smitten with these Mississippi Mud Brownies. A moist brownie layered with chocolate chips, topped with melted crunchy peanut butter, marshmallows, sprinkled with toasted pecans and lacquered with a thin layer of frosting. You want them don’t you?

Instantly, when my eyes fell upon TK member Taylor’s (greensnchocolate) recipe forMississippi Mud Brownies, I just knew I had to make them. I desperately felt the need to sink my teeth into these ooey-gooey sinful brownies! And these Mississippi Mud Brownies didn’t disappoint.

These brownies require a few basic pantry ingredients, and they take less than 30 minutes to prepare! I chopped the toasted pecans ahead of time to quicken the process a bit.

Start off by measuring the flour, cocoa powder and salt. Add them into a small bowl.

Stir to combine and set aside.

Cream the stick of butter along with a cup of sugar until light and fluffy.

Next add in the vanilla extract.

Add the dry ingredients in with the sugar/butter mixture and stir to combine.

Spread the brownie mixture into the bottom of a lined 8×8 square pan.

Sprinkle with chocolate chips and pop into a 350ºF oven for about 20-22 minutes.

Once the brownies have baked, here comes the really fun part.

Start by mixing oil in with some warmed peanut butter.

Then evenly pour the peanut butter all over the warm brownies.

Sprinkle 2 cups of marshmallows over the peanut butter. Bake in the oven for 3 minutes, just to puff up the marshmallows.

Top with the chopped toasted pecans and set aside to cool. Now it’s time to make the frosting!

In a small pan, melt 4 tablespoons of unsalted butter. Next add in the cocoa. Stir and gradually pour in the milk. Heat the chocolate mixture until just about boiling, remove from the heat and add the vanilla extract. You could also add the vanilla to the frosting once it’s been mixed.

In a mixing bowl that contains 2 cups powdered sugar and 1/8 teaspoon salt, pour in the warm chocolate mixture while the mixer is on low speed.

Scraping down the sides as you go, mix until the powdered sugar is absorbed into the chocolate. If the frosting looks too thick, add a tablespoon or two of milk to thin it out.

Pour over the pecans and marshmallows.

After I poured the icing over top, I realized my frosting must have cooled down too much because the icing didn’t melt into the crevices of the pecans and marshmallow. So I just spread the frosting out evenly. Once cooled enough, I placed the pan into the fridge for an hour or two.

It wasn’t until I removed the Mississippi Mud Brownies and pulled back the parchment paper did I realize what I was in for. These bars contain everything that I love in life. And it was almost too pretty to eat.

This is exactly what one needs to get over the cold weather and post holiday blues. Just be sure to pour yourself a giant glass of milk, because these brownies are rich and will definitely make you thirsty.

These Mississippi Mud Brownies were so much fun to make and definitely the most decadent brownie I have ever had the pleasure to taste!

    I've been on a brownie kick lately too! (in fact, just posted about them myself – double orange dark chocolate ones!)

    These sound great – I love the addition of marshmallows… very s'more like, and nice to add a softer texture to the mix!

    Pretty sure I just gained 5 lbs just from looking at that side shot of the brownie layers. I'm sure I'd probably gain 10 lbs more if I actually made these, but it would be totally worth it. 🙂

    I always thought Mississippi Mud treats had coffee in them. Regardless, these brownies look fantastic. I wish I had one right now!

    I've always wanted to try a mississippi mud brownie, because I've tried the pie version and loved it. Your brownies look absolutely incredible… I must have stared at that picture of the peanut butter being poured on them for a whole 2 minutes straight.

    These look SO good, but I missed the amount of ingredients for the actual brownies. Help?!

    I made a gluten free version of these for my mom (she has an allergy) and they were amazing! SOMEHOW I didn't have chocolate chips, so I used peanut butter chips and we were practically licking the pan afterward. 😀

    Kiri W. — January 23, 2012 at 3:04 pm

    Oh wow, this looks incredible! Soooo tempting! I don't think I'd include the marshmallows, just for personal taste, but other than that? Oooh, do I want one!

    A jar of peanut butter is the only thing that is keeping me away from making these treats. I think I need to make a trip to the grocery store for that peanut butter. These look delish!

    I just made these Mississippi Mud brownies for a friend's southern baby shower (who's from Mississippi). They were such a hit!! VERY rich and sweet, but perfect for a special occasion. Everyone asked for the recipe, and I passed along the link to your blog.

    I just made these for the second time. The first time my frosting was waaaay too runny because I ran out of powdered sugar…….. and substituted regular sugar for the remainder. I also don’t own an 8×8 square baking pan. SO, this time, I doubled the recipe and used a larger pan. But my frosting was still not anywhere near looking like yours…. Lol. However, it was thicker than the first time, so I guess that’s a win? They are cooling in the fridge now. Yum Yum Yum!
