Mississippi Mud Bars

Here’s one of my favorite Mississippi Mud Bar recipes. This is from an old book called Cookies by the Dozen. These are pretty gooey when they come out of the oven, so let them cool completely for you attempt to cut them into bars

Mississippi Mud Bars

Cooking Spray
1/2 cup unsalted butter, softened
1 cup granulated sugar
3/4 teaspoon vanilla extract
2 eggs
3/4 cup flour
2 tablespoons unsweetened cocoa powder
1/2 teaspoon salt
1/2 cup extra crunchy peanut butter
1 1/2 teaspoons vegetable oil
3/4 cup semi-sweet chocolate chips
2 cups miniature marshmallows
1/2 cup chopped toasted pecan pieces

Frosting:
2 cups confectioners sugar
1/8 teaspoon salt
1/4 cup unsalted butter
2 tablespoons unsweetened cocoa powder
1/4 cup plus 2 tablespoons milk
1/4 teaspoon vanilla extract

Preheat oven to 350 degrees F. Line an 8 inch square metal pan with parchment or foil. If using foil, spray it with cooking spray.

In a mixing bowl, beat together butter, sugar and vanilla. Add eggs one by one. Combine flour, cocoa powder and salt and stir into batter. Spread batter across bottom of prepared pan. Sprinkle top with chocolate chips. Bake for 20-22 minutes.

Meanwhile, combine peanut butter and oil in a microwave-safe bowl or measuring cup. Microwave on high for about 20 seconds to soften. Pour peanut butter mixture over hot cake. Sprinkle peanut butter covered cake with marshmallows and return to oven to bake for 3 more minutes or until marshmallows puff. Sprinkle puffed marshmallows with toasted pecans.

Place confectioners sugar into a large mixing bowl. Add salt. In a small saucepan, melt butter over medium heat. Stir in cocoa powder and 1/4 cup of the milk and heat just until mixture begins to boil. Pour hot mixture into sugar. Beat on high speed of electric mixer until smooth and glossy. If frosting is not pourable, add remaining milk. Beat in vanilla. Pour over puffed up marshmallows.

Let cool completely for 1 hour. Cut into squares. Makes 12
