There are lots of recipes for Mississippi Mud Brownies out there but this one is perfection. Moist brownies topped with marshmallows and a rich chocolate ganache. Everyone asks for this bar recipe when I make these.

(Originally posted 2015)

I just returned from a week long trip to Maui. All I can say is that the beauty of the island is overwhelming. While biking down Mt. Haleakala I saw plants and trees that looked so magical they almost looked fabricated. I feel lucky to have spent 1 of my 52 weeks in 2015 there. On the other hand, I was loaded with guilt for leaving my kids that long. Why don’t guys ever feel the guilt?

I know I’m a foodie because I find the same kind of beauty in food. Like these brownies. I fell in love with the buttery brownie base and now want to use it for any brownie I make from now on out. The brownies are topped with marshmallows and a rich ganache that I fell in love with too. The mixture of chocolate chips, cream, and a little butter cream creates the silkiest ganache I’ve ever had…and consequently now want to pour on everything.

These brownies get the same reaction every time. People take one off the plate, assuming that they’re regular old brownies, and then they take a bite. Every time they turn around and say, “These are soooo good! Can I have the recipe?”

The ganache topping for these brownies are silky and decadent.

Fold in some marshmallows.

Layer the marshmallow topping on the cooked brownies.

My neighbor Julie has made them a couple of times for me and hands down these were our favorite treat at Christmas this year. And after harassing her relentlessly I finally have the recipe!

PrintPinRate

Prep Time: 10 minutes mins

Cook Time: 25 minutes mins

Total Time: 35 minutes mins

Servings: 24 bars

Ingredients

Brownies:

4 ounces unsweetened chocolate, (like Bakers)
1 cup (2 sticks) butter
4 eggs
2 cups granulated sugar
1 Tablespoon vanilla extract
1/4 teaspoon salt
1 cup all-purpose flour

Chocolate Ganache-Marshmallow Topping:

2 cups (12 ounces) semisweet chocolate chips
3/4 cup heavy whipping cream
1 1/2 Tablespoon butter
3 cups mini marshmallows

Instructions

Preheat oven to 350 degrees and grease a 9x13 baking dish.
For the brownies: In a large glass bowl, combine the unsweetened chocolate and butter. Heat in microwave 1-2 minutes stirring intermittently until melted and smooth.
Beat in eggs, sugar, vanilla, and salt until well blended.
Stir in flour, blending well.
Spread evenly into prepared pan. Bake 25-30 minutes. Do not overbake! Brownies should be moist. Cool in pan.
For topping: Combine chocolate chips and cream in a large glass bowl. Heat in microwave 1-2 minutes stirring twice until melted and smooth. Add butter and stir until melted and smooth. Fold in marshmallows.
Spread topping evenly over the top of cooled brownies. Refrigerate several hours or overnight. Cut into bars. Store in the refrigerator.

Notes

Tips: Line the pan with heavy duty foil and then spray it. After brownies are done lift the whole pan of brownies out by the foil for easier cutting.

It says to sore in the refrigerator. Do you think I could use these for a bake sale or will they melt?
- Christy Denney — Tue, 07 Nov 2023 @ 02:46:41 EST Reply
  No they won’t melt. You could technically store at room temp

I’m so excited to try this, do you think I could use half n half instead of heavy cream, that’s all I have on hand. Thanks

If ever, but more likely never will we raise concern enough for people for this,
yes you can find all sorts of groups available doing excellent achievements plus some even going to extreme methods which ultimately ends up like a negative image for
group and cause. Online editions have categorized different news items
including world business news, international business news, news in middle east,
and Islamic news, to offer additional information because
the event progresses every seconds from the day.
However, he formed the habit of stopping “just for any drink or two” with
friends after work.

  It’s in inches. Never can be too safe!

  I beat with a mixer but you could do it by hand.

do you whip the cream?

I’m supposed to bring a peanut butter & chocolate dessert to lunch. Do you think I could substitute Reese’s
Cups for the marshmallows?
Thanks!
- Christy Denney — Tue, 21 Apr 2015 @ 22:53:58 EDT Reply
  Um yes! I love the texture the marshmallows gives it though. Maybe do both marshmallows and pb cups?

      No! Don’t whip the cream. I would include that if needed. Just straight whipping cream.

What?! You were on Maui & I missed you? How is that even possible? I looked for you at the conference & Todd said he didn’t see John. Major bummer. Did you bring the kids? Please tell me your coming to the conference here next year.
- Christy Denney — Mon, 23 Mar 2015 @ 22:17:04 EDT Reply
  We were at the Ritz for the NFLPA conference. you were there?!!
  - Sara Watkins — Tue, 24 Mar 2015 @ 01:26:17 EDT Reply
    Yes, ma’am! The former player convention Wednesday-Friday so we went on over. So crazy! All the events Wednesday were joint so if John golfed or you went to the luau then we literally walked right by each other & I never got to thank you in person for saving my cooking sanity. You should definitely bring the kids along next year. My boys loved it & we have a few girls from our ward who tag along to the hotel to help with babysitting.

      Nice! So we were supposed to golf but got back too late from Molokini! Then we missed the joint dinner because we flew out early. Next year for sure!!

In #7, did you mean to spread the topping over the cooled brownies? You wrote to spread over the cooled marshmallows.
For those of us who can’t live without nuts, I would spread 11/2 cups chopped, toasted pecans on top of the brownies when they come out of the oven. Then put the chocolate-marshmallow topping over the pecans.
