Are you thinking: what the heck is a Mud Hen Bar? Good, me too.

As far as I can tell, a Mud Hen Bar is a cookie bar that’s been topped with a brown sugar meringue. Supposedly they’re a southern treat, and they’ve been around for years. I first discovered them back in 2012. I’d never heard of them before but I was super intrigued by that brown sugar meringue.

I kind of have a secret crush on brown sugar. If I could use it exclusively, I would.

Back in 2012, I threw the mud hen together with brownies and it was probably the best dessert I’d made up to that point (and, in all honesty, it’s rarely been beaten since). The gooey factor alone drives me to a frenzy whenever I think about them!

I’ve been wanting to do another mud hen version ever since. Traditionally, the base of a mud hen is a plain cookie. Then the cookie is sprinkled with chocolate chips and marshmallows.

I decided to skip the marshmallows (read: I forgot about them) and I also decided to use my favorite chocolate chip cookie recipe for the bar.

I cut them while they were still a little warm. I like gooey chocolate.

So will you. These are AMAZING!

Did you know that May 15 is National Chocolate Chip Cookie Day? When I realized that and remembered I had these bars in my archive, I knew it was time to post them. A day like chocolate chip cookie day needs to be celebrated!

These bars are super easy to make. I’m totally into super easy lately. Ain’t nobody got time for tons of steps!

Step one: Make cookie dough. Press into pan.

Step two: Whip egg whites with brown sugar. (I prefer to do this in a stand mixer – then you can walk away during mixing.)

Step three: Bake. The meringue gets brown and crunchy and the cookie stays ooey gooey.

Step four: Eat straight from the pan with a fork.

If you like crunchy meringue, brown sugar, and chocolate chip cookies, then you’ll love mud hen bars.

These are hide-in-a-closet bars. As in, I’m hiding in a closet with a fork so no one sees me eat the whole pan. And they’re great for parties because (1) you get rid of them without eating them all yourself and (2) people ooooh and aaaaah because they’re something so much more than a cookie.

Meringue is one of those things that’s so easy to make, but people are wowed by it. Use that to your advantage. Bring the star dessert to the end of the year potluck!

Chocolate Chip Cookie Mud Hen Bars

A gooey chocolate chip cookie bar covered in brown sugar meringue!


  • 1/2 cup unsalted butter — softened
  • 1/4 cup granulated sugar
  • 1 1/2 cups packed brown sugar — divided
  • 1 large egg + 2 egg whites — divided
  • 1 teaspoon pure vanilla extract
  • 1/2 teaspoon baking soda
  • 1 1/2 cups all-purpose flour
  • 1/4 teaspoon salt
  • 1 cup chocolate chips


  1. Preheat oven to 350°. Line an 9x9” pan with foil and spray with cooking spray.
  2. Whisk flour, baking soda, and salt in a medium bowl. Stir and set aside.
  3. Cream butter, granulated sugar, and 1/2 cup brown sugar until combined. Turn mixer on low. Add 1 egg, mixing completely. Mix in vanilla extract. Add flour mixture to the wet ingredients and mix until combined. Mix in 1 cup chocolate chips. Press into prepared pan. Chill dough until egg whites are ready.
  4. Beat 2 egg whites with a mixer fitted with the whisk attachment until stiff peaks form (about 3-5 minutes on speed “6” if using a stand mixer). Sprinkle 1 cup of brown sugar over the beaten egg whites, making sure there are no clumps. Fold in the brown sugar and spread evenly over the cookie layer.
  5. Bake for 28-33 minutes or until the meringue is golden brown. If the top starts to brown too quickly, cover it with a layer of parchment paper. Let cool to at least room temperature before cutting. (Chill in the refrigerator for quicker cooling.) Peel away the foil carefully before cutting. **Be sure to spray your knife with cooking spray before cutting. After each cut wipe away excess and spray the knife again.**
