What are Mud Hen Bars?

I have no idea why they are called “Mud Hen Bars” but when I googled the name, I discovered there is a Mud Hen, New Jersey. Maybe that is where they originated??   No matter what you call it, it is the perfect dessert solution to any chocolate, marshmallow, ooey, gooey craving you may be having!

mud hen bar ingredients

Ingredients Needed

  • Butter. I use salted butter
  • Eggs
  • Flour. I prefer unbleached all purpose flour
  • Baking powder
  • Salt
  • Chocolate chips
  • Mini marshmallows
  • Brown sugar
  • Granulated sugar

How to Make Mud Hen Bars

  • Cream the butter and sugar in the bowl of a stand mixer with the paddle attachment.
  • Beat in the whole egg and 2 egg yolks
  • Sift flour; baking powder and salt together in another bowl and then combine the two mixtures, blend thoroughly.
  • Spread cookie dough in lightly greased 9 x 13 pan.

  • Sprinkle cookie crust with chocolate chips chips and marshmallows.
  • Beat 2 egg whites until stiff peaks form and fold in brown sugar.

  • Spread over top of cookie base.
  • Bake 30-40 minutes at 350 degrees
  • Cool and cut into bars

Brown Sugar Meringue Topping

My favorite part of this bar cookie is the meringue like topping. It is made by whipping egg whites and folding in brown sugar and then spreading it over the top of the marshmallows and chocolate chips. This creates a delicious crunchy topping as it bakes.

So next time you have a chocolate and marshmallow craving or need to take a bar cookie somewhere give them a try and let me know what you think.

Frequently Asked Questions

Can I add nuts?


If you are fan of nuts in your baked goods, you can sprinkle a cup of chopped nuts on top of the cookie base along with the chocolate chips and marshmallows. You could also chop up the nuts and include them in with the cookie base if you prefer.

How long will Mud Hen Bars last?

These bars are the best the day they are made and are amazing warm, fresh out of the oven. They are good the next day but by far the best the day they are made. Because of the meringue top they do not freeze well or travel well.

  • Lemon Meringue Ice Cream
