I am a serious lover of chocolate, there's no denying it. And the creamier and silkier the dessert is, the better. Mississippi Mud Pie is a traditional chocolate pie which I suppose does resemble mud in some way, but definitely not in taste thankfully. The filling is a creamy combination of melted chocolate, cocoa, eggs and dark brown sugar. Don't be mistaken and use regular brown sugar which is called for in most other desserts, it's that dark rich molasses flavor that makes a mud pie taste so good. It's a little similar to a dense chocolate cheesecake.

Making your Mississippi Mud Pie Bars

You'll need to make the base first. It's a mixture of all purpose flour, powdered sugar, butter and cocoa powder. It's the same base I use for my Buttery Orange Bars minus the cocoa powder. It doesn't form a stiff dough like a regular shortbread base, but as it cooks in the oven the butter melts and brings the other ingredients together until firm. You can make the base a few hours ahead of time if it helps.

Ingredients you'll need for the filling

  • butter, unsalted
  • dark brown sugar
  • large eggs, at room temperature
  • cocoa powder
  • dark chocolate, 72% is perfect
  • heavy cream

Tips for making Mississippi mud pie bars

  • Make sure the butter is at room temperature before beating it with the sugar.
  • Add the eggs one at a time making sure to scrape the sides of the bowl down with a spatula.
  • Melt the chocolate in the microwave but do this gradually as chocolate can burn easily in the microwave.
  • You'll know when the mud pie bars are done when the center looks dry and it no longer jiggles when gently shaken.

Once the mud pie bars are completely cool, you can go ahead and slice them into squares. Top each square with a swirl of whipped cream and garnish with chocolate shavings.
