What is Mississippi Mud Pie?

There is chocolate pie, and then there is this old-fashioned Mississippi mud pie recipe – the original fix for every chocoholic’s most serious chocolate craving!

Mississippi mud pie is what happens when you combine a chocolate chess pie with a flourless cake, and, let me say, the result is fantastic.

My recipe is in line with a traditional Mississippi mud pie recipe. There are no extra bells and whistles – just the classic combination of a chocolate cookie crust, decadent chocolate pie filling, and a rich ganache to top it off.

What is in a Mississippi Mud Pie?

A Mud Pie has 3 layers: the crust, the chocolate chess pie filling, and the ganache topping.

  • Oreo Crust: You’ll need to crush Oreo cookies and no, you don’t need to remove the filling. For tips, see my post on how to make an Oreo Cookie Crust.
  • Unsalted Butter: You’ll use this to make the crust and in the filling of the pie.
  • Chocolate: For the pie filling, you’ll need chopped semisweet baking chocolate. That’s the kind you get in the baking aisle.
  • Eggs: You’ll need large eggs – and an extra egg white. This helps make the creamy filling of the pie.
  • Bittersweet chocolate chips: These are to make the ganache. You can substitute semi-sweet.

How to Make Mississippi Mud Pie

The pie has a few steps but it’s worth every single one – we have to make the crust, the fudgy brownie-like filling, and the ganache topping.

1. Make the crust by crushing the cookies in a food processor until they are broken down into fine crumbs. Next, transfer them to a bowl, add melted butter, and stir with a fork to combine.

Expert Tips

  • One thing I love about this pie is how ooey-gooey it is! So, I make it a day ahead and keep it covered at room temperature. This allows time for it to set and still have that great gooey texture when you serve it.
  • If you’re in a rush, you can chill the pie, so it sets faster. However, the texture will be fudgier if you serve it cold.
  • For the ganache, feel free to use semisweet chocolate chips if that’s what you have on hand.
  • Store the pie in the refrigerator. If you want it gooey when you serve it, let it come to room temperature first. If you serve it cold, the texture will be fudgier.
  • You can freeze Mississippi mud pie, but it won’t be as good once it’s thawed.

FAQs

Can I use a pie pan? 

Yes, a 10″ pie pan works great for this recipe, too.

Why do I have to bake it on a cookie sheet?

Springform pans can leak sometimes, and it’s better to have a pan under the pie to catch any leaks, so they don’t burn on the bottom of your oven.

Why didn’t my ganache set?

Be sure to measure the ingredients accurately. Also, you need to use heavy cream to make the ganache. Regular milk or half and half won’t work.

How do you know when mud pie is done baking? 

The pie should be set in the middle and be puffy and slightly cracked on top.

Instructions

  • Make the crust: Preheat oven to 350°F. Grind the Oreos in a food processor until they are a fine crumb. Place in a bowl and stir in melted butter with a fork. Press into the bottom and up the sides of 9-inch or 10-inch springform pan. (You can also use a 10-inch pie plate.) Chill until ready to fill.
  • Make the filling: Place butter and chocolate in a medium sized bowl. Melt in the microwave, heating on high in 30 second increments, stirring between each, until the chocolate is melted and smooth. (You can also do it in a bowl set over a pan of simmering water.)
  • Once the chocolate is melted and smooth, whisk in the flour, sugar, vanilla, and salt. Whisk in eggs and egg white, one at a time, until the mixture is smooth. Pour mixture into prepared crust. You can use a hand mixer if you want, but it's easy just to whisk it.
  • Place pan on a cookie sheet (very important as some of the butter might leak out of the springform pan since those pans are not sealed). Bake until the top is puffed and filling is set in the center, 35-45 minutes. Let cool 1 hour.
  • Once the pie has cooled for about an hour, make the ganache: Place the chocolate chips in a medium heat safe bowl. Bring the cream to a simmer in a small saucepan then pour hot cream over chocolate chips. Let sit 30 seconds then stir until the chocolate is completely melted.
  • Spread the ganache over the pie, spreading it to the edges of the crust.
  • You can let this set overnight at room temperature, covered with plastic or you can chill to set.
  • Serve the pie at room temperature for ultimate gooiness (if it’s cold it will be more like fudge). Optional serving suggestion: top with whipped cream or sprinkle with sea salt.

Recipe Notes

  • Be sure to put the springform pan on a cookie sheet to bake. Those pans aren’t sealed and some of the butter from the crust might leak out.
  • You can use a 10-inch pie plate if you prefer.
  • You can also make the ganache with semi-sweet chocolate chips or milk chocolate chips if you prefer.
  • Make the crust with chocolate graham crackers instead using my graham cracker crust recipe.
  • You can top the pie with chocolate curls instead of crushed cookies.

  1. If you like chocolate, you’ll like this pie! It’s rich and chocolatey and I’d recommend having it with whipped cream. The only thing I might do differently is make the crust a bit thinner.
