Mississippi Mud Brownies are the richest, most delicious brownies ever! A layer of brownies topped with layers of peanut butter, marshmallows, and toasted pecans. Then they get topped with a thick layer of chocolate frosting.
I didn’t plan on sharing these Mississippi Mud Brownies with y’all.
I was so disappointed with how they looked when they came out of the oven and even more disappointed with my photos.
But then the other night I had a Lean Cuisine for dinner and then chased it with 3 of these and decided that ehh, they might be hideous but they were way too good to not share!
How To Make Mississippi Mud Brownies
There are a take on the classic Mississippi Mud Pie which is typically a a chocolate cookie crust with a rich cake baked into it. Then it gets chocolate pudding on top of the cake and finally, a layer of freshly whipped cream and some chopped pecans.
For theese Mississippi Mud Brownies, you make a fairly standard brownie recipe but then you cover them with peanut butter, marshmallows, pecans, and a deliciously rich chocolate frosting.
All my favorites.
Which means these regular brownies become magical brownies and before you know it, you’ll have eaten 3 of them while staring out your kitchen window at absolutely nothing. They are just so rich and delicious!
These are so quick and such an easy way to jazz up the regular brownie. You could even start with a brownie mix which is probably what I’ll do next time just to make it even easier.
And yeah, I will definitely be making these again. And again and again!
That good.

Sorry I read the recipe again and there is powdered sugar in frosting. I was looking at line items below the frosting ingredients and didn’t see it listed. It was listed above instead. I see where you added it in the frosting as I read the remainder recipe. Thank you. Sorry I was wrong. Hadn’t had my morning coffee yet! ????
Heather says
These look so good and pics look great! Don’t sell yourself short! I would eat 3 too! I have a similar recipe without peanut butter but I am a little confused on the frosting ingredient? Did you leave something out? I’m think it needed powdered sugar as one of the ingredients listed. Maybe 1lb? Please advise. Thank you so much for this amazing recipe. Can’t wait to try it!

I was so glad to read that the marshmallows get puffed! I love melty marshmallow, but cold, just out of the packet marshmallow does nothing for me. YUM.
Lesa @Edesia's Notebook says
Yum! I definitely would use a brownie mix too, because I am lazy! But these look so good. Pinned!
