Method
 

  1. Preheat your oven to 350°F (175°C). If you are using a homemade pie crust, blind bake it according to your recipe's instructions until lightly golden and set. If using a pre-made crust, ensure it is ready to be filled.
  2. In a large heatproof bowl, melt the 1 cup of unsalted butter. You can do this in the microwave in 30-second intervals, stirring between each, or in a double boiler over simmering water.

  3. In a separate medium bowl, whisk together the 1 ½ cups of granulated sugar, 1 cup of unsweetened cocoa powder, ½ cup of all-purpose flour, 1 teaspoon of instant espresso powder (if using), and ½ teaspoon of salt. Ensure there are no lumps.

  4. To the melted butter, add the 4 large eggs one at a time, whisking well after each addition until thoroughly combined. Stir in the 1 teaspoon of vanilla extract.

  5. Gradually add the dry ingredient mixture to the wet ingredients, whisking constantly until a smooth, thick batter forms. Be sure to scrape down the sides and bottom of the bowl to incorporate all the dry ingredients.
  6. Gently fold in the 8 ounces of bittersweet chocolate chips and the chopped nuts (if using) into the batter. Mix until they are evenly distributed throughout the chocolate mixture.

  7. Pour the rich chocolate batter into your prepared pie crust. Spread it evenly with a spatula, making sure to fill the crust without overflowing.

  8. Carefully place the pie on a baking sheet (to catch any potential drips) and bake in the preheated oven for 30-35 minutes. The center should be set but still slightly fudgy. A toothpick inserted near the center might come out with moist crumbs, which is perfect.
  9. Remove the pie from the oven. Immediately scatter the 1 cup of miniature marshmallows evenly over the hot surface of the pie. The residual heat from the pie will begin to melt and puff them up.

  10. Return the pie to the oven and broil on the top rack for 1-2 minutes, watching *very* carefully. You want the marshmallows to be lightly golden and toasted, not burnt. This step is quick, so stay present!
  11. Remove the pie from the oven and let it cool completely on a wire rack for at least 2-3 hours. This allows the filling to set properly. For best results and an even firmer set, chill the Best Mississippi Mud Pie in the refrigerator for at least 4 hours, or preferably overnight.
  12. Once chilled, slice the Best Mississippi Mud Pie into wedges and serve with a generous dollop of fresh whipped cream.
