Mud Hen Marshmallow Dessert Bars Recipe

Sometimes names can be deceiving.

Haven’t you ever met a person and been like, yeah…your parents SO should have named you Jan and not Heather?  Or Brody and not Chuck? It happens.

Same thing happened with these bars. They’re called Mud Hen Bars. Which is basically the grossest name ever. Mud is not tasty…Hens are all pecky and whatnot… And the google told me a “Mud Hen” is a gross marsh bird that lives in swamps and other wetland-type areas.

Well, I am not a bird-fan in general.  They scare me.  I mean, they can fly.  Think about it. AND Mud Hens are not only birds, they live in swamps.  Swamp birds.  Could there be a worse type?

But defying all laws of logic I made these Mud Hen Bars. They sound gross. But they aren’t. They’re exactly the opposite.

This Mud Hen Bars recipe is really easy.

What is a Mud Hen Bar?

The best way to describe Mud Hen Bars is they are is a kind-of cookie base, topped with chocolate chips and marshmallows with a yummy brown sugar meringue spread all over the top.

How to Make This S’mores Dessert

Just sprinkle your chips and marshmallows…

Then mix up your meringue, which is just brown sugar and egg whites…

Do I really fold in the sugar and not beat it in? Folding brown sugar doesn’t sound like it would ever incorporate correctly/fully and would come out grainy…

Mud hens are a Triple A baseball team in Toledo, Ohio. Sometimes stadium treats get called by the ball park name when people try to dupe them at home. I wonder if this might be on of those recipes.

I can’t wait to try these, I’m a sucker for gooey marshmallow and chocolate.

The meringue was delicious but the cookie was very undercooked. ?I will try them again & increase the bake time.

I found this recipe (minus the marshmallows) in the newspaper in the 1960s or 70s and have been making them ever since–they are a favorite! They were not called Mudhens, though, but Chocolate Chip Meringue Bars.

As I looked at the description for making these bars I noticed a descrepency in how to make the Meringue. It says to add 1 brown sugar to the beaten egg whites. Is that supposed to be 1 cup of Brown sugar? Sorry if there was already a correction made. I’m anxious to try these for our church pitluck this Sunday so I hope U see this soon. Thank U.

I am going to make these for church. Would like to make them 2-3 days ahead of time. Will they be as good or should I wait until the day before?

These bars look delicious, but I have to disagree with you regarding mud hens! They are cute! We have them all over Florida waterways. 🙂

My son has a dairy allergy…do you think it would work to use coconut oil in place of the butter? These look amazing!

A friend gave me this delicious recipe a good 40 years ago and yes it was called MudHen Bars even then. You cannot go wrong with these bars. Have made them many times and enjoy seeing this recipe again. Thank You!!

These are fabulous. Speaking of gross names for food, I make a cookie and we always called the “Cow Patties” when we were kids, the name has stuck through the the years.

These are amazing. Loved the crunch on top and chew underneath. I added white chips and MnMs to the cookie base since I had some to use up. Highly recommend!
