Description

Fudgy, gooey, and irresistibly rich, these Mississippi Mud Cake Brownies combine a dense chocolate base with marshmallows, pecans, and a silky chocolate frosting. A true Southern-inspired treat that’s worth every bite.


Ingredients

Scale
  • 1 cup unsalted butter, melted
  • 2 cups granulated sugar
  • 4 large eggs
  • 2 teaspoons vanilla extract
  • 1 1/2 cups all-purpose flour
  • 1/2 cup unsweetened cocoa powder
  • 1/2 teaspoon salt
  • 4 cups mini marshmallows
  • 1 cup chopped pecans
  • 1/2 cup butter (for frosting)
  • 1/3 cup cocoa powder (for frosting)
  • 1/4 cup whole milk
  • 3 cups powdered sugar
  • 1 teaspoon vanilla extract (for frosting)


Instructions

  1. Preheat oven to 350°F (175°C). Grease or line a 9×13-inch baking pan.
  2. In a large bowl, whisk melted butter and sugar until smooth. Beat in eggs one at a time, then add vanilla.
  3. In another bowl, whisk flour, cocoa powder, and salt. Gradually mix into wet ingredients.
  4. Pour batter into the prepared pan and spread evenly. Bake for 25–30 minutes or until a toothpick comes out mostly clean.
  5. Remove from oven and scatter mini marshmallows evenly over the top. Return to oven for 3–5 minutes, until marshmallows puff up.
  6. Sprinkle with chopped pecans.
  7. In a saucepan, melt butter for the frosting. Stir in cocoa powder and milk until smooth. Remove from heat and whisk in powdered sugar and vanilla extract.
  8. Pour frosting over marshmallows and pecans. Let cool completely before slicing.

Notes

  • Use high-quality cocoa powder for deeper chocolate flavor.
  • Let the brownies cool fully before frosting for cleaner layers.
  • Store leftovers in an airtight container to retain moisture.
  • For clean slices, chill brownies and use a hot knife.
