Mississippi Mud Bars

Rich, gooey chocolate bars made from a cake mix base topped with marshmallows and chocolate chips, perfect for potlucks and bake sales.

  • Total Time: 30 minutes
  • Yield: 12 squares 1x

Ingredients

Scale
  • 1 box Super Moist Cake Mix
  • 1/2 cup unsalted Butter, melted
  • 1 Large Egg
  • 2 cups Mini Marshmallows
  • 1 cup Chocolate chips
  • 1 cup Powdered sugar
  • 2 tablespoons Cocoa powder
  • 3 tablespoons Milk
  • 1 teaspoon Vanilla extract

Instructions

  1. Preheat the oven to 350°F (175°C) and grease a 9×13 inch baking pan thoroughly.
  2. Combine the cake mix, melted butter, and egg in a large bowl until the mixture is uniform and slightly thick.
  3. Spread the cake mixture evenly into the prepared pan using an offset spatula for a flat surface.
  4. Bake the pan for about 15 to 20 minutes, or until the center is set but still slightly soft to the touch.
  5. Remove the pan from the oven immediately when set to prevent over-browning around the edges.
  6. Sprinkle the mini marshmallows evenly across the hot base immediately after removing from the oven.
  7. Scatter the chocolate chips over the marshmallows so they nestle into the top surface.
  8. Return the pan to the oven for an additional five minutes, or until the marshmallows appear puffed and glossy.
  9. Whisk the powdered sugar, cocoa powder, milk, and vanilla extract in a separate bowl until smooth and pourable.
  10. Drizzle the icing over the warm bars using a spoon or small piping bag for even coverage.
  11. Allow the bars to cool completely in the pan before cutting into squares to ensure clean slices.

Notes

For best results, measure the ingredients accurately and avoid overbaking.
