Mississippi Mud Bars
If you've never had one of these Mississippi Mud Bars, you're in for a treat. A firm cookie layer, topped with nuts, chocolate chips and marshmallows, and then covered in a unique meringue flavored with brown sugar, these treats are the essence of Southern decadence.
Servings: 36 Bars
Calories: 180kcal
Ingredients
- 1/2 Cup Butter
- 1 Cup Granulated Sugar
- 2 lg Eggs separated and reserved
- 1 1/2 Cup All-Purpose Flour
- 1 tsp Baking Powder
- 1/2 tsp Salt
- 1 Cup Chopped Walnuts
- 1/2 Cup Semisweet Chocolate Chips
- 1 Cup Miniature Marshmallows
- 1 Cup Brown Sugar dark, firmly packet
Instructions
- Preheat oven to 350° F
- Line a 13 X 9" baking pan with parchment, so that the parchment drapes over the side by about 1". This will be a handle for you to lift out the bars.
- Whisk together the flour, baking powder and salt. Set aside.
- Cream together the butter and sugar until light and fluffy - about 3 minutes on medium. Beat in the egg yolks, one at a time, just until blended.
- On the lowest speed, fold in the flour mixture until all is uniformly moistened.
- Press the mixture into the prepared baking pan and pack down firmly. Sprinkle the nuts, chips and marshmallows over the top of the mixture in the pan.
- In a large bowl, beat the egg whites until stiff peaks form. With a spatula, fold in the brown sugar, trying to keep as much air in the whites as possible. Spread over the mixture in the pan.
- Bake for 35 minutes or until a crust is formed. Remove from oven and let cool in the pan for 5 minutes, then remove to a rack to cool completely.
- Cut into squares and serve.
Notes
Don't stress too much about the egg whites. You'll be folding in brown sugar, which is going to collapse them quite a bit anyway.
