Mud Hen Bars are gooey, chewy and delicious cookie bar base topped with chocolate, marshmallow and a brown sugar meringue!
I have no idea why they are called Mud Hen Bars, but they are delicious. It is the perfect combination of chocolate and marshmallow.
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.

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.
