Two Peas and Their Pod

Mud Hen Bars

I was looking for a bar treat to make for a party and stumbled across a recipe for Mud Hen Bars. The bars have a cookie crust and are topped with marshmallows and chocolate chips. Wait, there is more! The bars also have a brown sugar meringue topping. I wasn’t sure where the “Mud Hen” name came from, but I didn’t care. I was going to make the bars anyways.

Mud Hen Bars Recipe on These bars are always a hit! Easy to make too!

First, you make a basic cookie dough crust and top it with mini marshmallows and chocolate chips. You can add chopped nuts, but I left them out since Josh is allergic and I really don’t care for nuts in my cookies and bar treats.

Next, you beat the egg whites until they form stiff peaks and gently fold in the brown sugar.

You cover the bars with the meringue topping and bake for about 30 minutes. And then you impatiently wait for the bars to cool so you can can cut and devour them. Oh wait, these were for a party so I couldn’t devour them all, but I did sneak a taste. I loved the cookie base, but the best part of these bars is the brown sugar meringue topping. The topping is sweet, crackly, and melts in your mouth.

Everyone at the party loved these bars and wanted the recipe. When I told them they were Mud Hen Bars, they looked confused. I told them not to worry because I don’t know why they are called Mud Hen Bars either:) I still have no idea, but I don’t really care. All I know is that these bars are super duper delicious and that is all that matters to me!

Mud Hen Bars

Yield: 24 bars

Cook Time: 30 minutes


1/2 cup butter, at room temperature
1 cup granulated sugar
3 large eggs, divided (1 egg, 2 yolks, and 2 egg whites)
1 teaspoon vanilla extract (I added this)
1 1/2 cups all-purpose flour
1 teaspoon baking powder
1/4 teaspoon salt
1/2 cup semi-sweet chocolate chips
1 cup mini marshmallows
1 cup chopped nuts (I left these out)
1 cup light brown sugar


1. Preheat oven to 350 degrees F. Grease a 9x13 pan and set aside.

2. In the bowl of a stand mixer, beat together butter and granulated sugar until creamy. Beat in 1 whole egg and 2 egg yolks (put aside the whites for later.) Beat in the vanilla extract.

3. In a separate medium bowl, whisk together the flour, salt, and baking powder. Add the dry ingredients to the wet ingredients. Blend until just combined. Spread mixture into 9x13" pan. Sprinkle with marshmallows, chocolate chips, and nuts-if using.

4. Beat egg whites until stiff peaks form. Gently fold in the brown sugar. Spread mixture evenly over marshmallows and chocolate chips. Bake for about 30 minutes or until bars are a deep golden brown. Let bars cool completely. Cut into squares and serve.

    I just posted about some bars I made earlier today…marshmallows, white choc chips, peanut butter, 4 layers of cake and goo and frosting.

    After those bars are done, I want to make your Mud Hen bars!!!!

    How fun are these? Love the marshmallow addition! I don’t like nuts in my baked goods either (except granola)

  12. The Blue-Eyed Bakers — August 8, 2011 @ 9:49 am

    Um hello delicious. Chocolate chips and marshmallow are our baking kryptonite – we cannot resist!

    These looks so yummy! I’ve never heard of “Mud Hen Bars” either–but it sure is a fun name. I’ve sometimes heard Magic Cookie Bars called “Congo Bars” too, so go figure, I guess. :)

  16. The name is intriguing. They look delicious!

  28. CouponClippingCook — August 8, 2011 @ 11:49 am

    What a fun recipe. Sounds delicious and it’s different….and the name is a great conversation piece.

  29. Georgia Pellegrini — August 8, 2011 @ 12:03 pm

    These look so tasty… what a funny name! Thanks for introducing me to them.

  30. Joanne — August 8, 2011 @ 12:40 pm

    It seems like an irrational twist of fate that I’ve never seen or heard of these before.

  31. The meringue topping sounds so yummy! Awesome recipe.

  33. Sara — August 8, 2011 @ 1:00 pm

    I’m from Toledo, OH, and our minor league baseball team is the Toledo Mud Hens. Maybe these are somehow connnected?

  34. Kat — August 8, 2011 @ 1:32 pm

    Whoa, that is for someone with a sweet tooth!

  35. Tanya @ Sunday Baker — August 8, 2011 @ 1:32 pm

  36. DessertForTwo — August 8, 2011 @ 1:42 pm

    I’ve been working on scaling these down to serve two! One of my favorites! :)

  37. VickiD — August 8, 2011 @ 1:50 pm

    perhaps the name is from MASH, Cpl Klinger’s Toledo Mud Hens? I’m saving this recipe for when I need something to give away, or else cut into very small pieces

  38. Marty — August 8, 2011 @ 2:15 pm

    Are these legal? :) They look scrumptious !

  39. Tickled Red — August 8, 2011 @ 2:56 pm
