Mississippi Mud Brownies recipes are easy to come by, but I particularly like this one. The bars are made in a 13×9 inch pan and feed a crowd.
Since I couldn’t wait to take the photo, the “mud” in this picture hasn’t hasn’t quite set and the bars still look a little gooey, but after a few hours in the refrigerator, the mud (which is icing, of course) firmed up.
If you like the idea of Mississippi Mud Brownies but want a smaller batch, here’s an 8 inch square pan recipe for Small Batch Mississippi Mud Bars.
Mississippi Mud Brownies
8 oz unsalted butter (230 grams)
4 ounces unsweetened chocolate, cut up (114 grams)
2 cups granulated sugar (380 grams)
1 cup all-purpose flour (130 grams)
¾ teaspoon salt (use 1/8 if using salted butter or margarine)
4 large eggs
3/4 teaspoon vanilla extract
1 cup pecans, toasted and chopped
About 3 cups miniature marshmallows
2 oz unsweetened chocolate
4 oz unsalted butter
1/2 cup evaporated milk
1/4 teaspoon salt (omit if using regular butter or margarine)
5 cups sifted powdered sugar (measure after you sift)
Preheat oven to 350 degrees F. Line a 13×9 inch metal pan with foil and spray the foil with cooking spray.
Melt the butter and chocolate together in a large saucepan (3 qt). Remove from heat and let cool slightly (only about 5 minutes).
Mix together the sugar, flour and salt and add to the chocolate mixture. Beat in the eggs and vanilla then stir in the pecans. Pour into pan and bake for 25-30 minutes.
Remove hot pan from oven and sprinkle marshmallows evenly over the top. Make the frosting.
Frosting: Melt the chocolate and butter together in a saucepan. When they are just about melted, add the milk and stir until smooth. Stir in salt if using.
Place powdered sugar in a mixing bowl. Pour the chocolate mixture into the sugar and stir well. Using a hand held electric mixer, beat until smooth. Pour over marshmallows. Let cool at room temperature for about an hour then move to the refrigerator to chill and set. When ready to serve, lift from pan and carefully cut into bars. Makes about 2 dozen.
