  • 2 pieces 2 eggs
  • 1/2 cup 1/2 cup vegetable oil
  • 2 tablespoons 2 tablespoons water
  • 2 cups 2 cups mini marshmallows
For the Icing
  • 1/4 cup 1/4 cup salted butter
  • 2 tablespoons 2 tablespoons Hershey’s unsweetened cocoa
  • 4 to 6 tablespoons 4 to 6 tablespoons milk
  • 1 teaspoon 1 teaspoon vanilla extract
  • 1 2/3 cups 1 2/3 cups confectioners’ sugar
  • 1/2 cup 1/2 cup toasted chopped pecans
  • 1 spray non-stick cooking spray

Method
 

Preparation
  1. Pre-heat oven to 325 degrees F. Spray an 8×8 inch baking pan with non-stick cooking spray. Set aside.
  2. In a medium mixing bowl, add brownie mix, eggs, oil, and water; mix well, being careful not to over mix.
  3. Spoon into prepared baking dish.
Baking
  1. Bake for 35 to 40 minutes or until a toothpick comes out partially clean.
  2. Remove brownies from oven and sprinkle marshmallows evenly over top. Return to oven and bake for 3 to 5 minutes or until marshmallows are puffy and lightly browned.
  3. Remove from oven and let cool completely.
Icing Preparation
  1. Once brownies have cooled, prepare icing: In a medium saucepan over low heat, melt butter.
  2. Stir in cocoa and whisk until smooth. Stir in 4 tablespoons of milk and vanilla.
  3. Slowly stir in confectioners’ sugar. Cook for 2 minutes or until thoroughly heated; icing should be pourable.
  4. If too thick, stir in 1 tablespoon of milk at a time until desired consistency is reached.
Final Assembly
  1. Immediately pour icing evenly over marshmallow topped brownies. Sprinkle pecans over the top.
  2. Cover and place in fridge to let icing set (approx 30 minutes) before serving.
  3. Store covered at room temperature.

Notes

For best results, serve with lightly whipped cream or vanilla bean ice cream. Store leftovers in an airtight container.
