How to Make Mud Hen Bars
Step 1: Prepare Your Pan and Preheat the Oven
Start by getting your oven nice and hot at 350°F (177°C). Line a 9×13-inch baking pan with parchment paper—this will make removing and slicing your Mud Hen Bars a breeze later on.
Step 2: Cream Butter and Sugar
In a large bowl, cream the softened butter together with 1 cup of packed brown sugar. Beat until the mixture is light, fluffy, and totally irresistible—this is the backbone of that rich, melt-in-your-mouth base.
Step 3: Add Egg and Vanilla
Crack in the egg and splash in the vanilla extract, then beat until smooth and well combined. These ingredients bring unity and extra depth to the dough.
Step 4: Whisk and Add the Dry Ingredients
In a separate bowl, whisk together the flour, baking powder, and salt. Gradually mix the dry ingredients into the wet mixture, stirring until just combined—no need to overmix! The dough should look soft but hold its shape.
Step 5: Spread the Dough and Add Toppings
Dollop the dough into your prepared pan and spread it evenly to the edges. Sprinkle the marshmallows, chocolate chips, and pecans in a generous, even layer on top. Each bite of your Mud Hen Bars will have a magical burst of flavor and texture.
Step 6: Make the Brown Sugar Meringue
Using a scrupulously clean bowl and beaters, whip the two egg whites until they hold stiff peaks. Gently fold in the remaining 1 cup of brown sugar until fully incorporated. This meringue layer is key to the signature crackly top of Mud Hen Bars.
Step 7: Top and Bake
Spoon the brown sugar meringue over the assembled base, spreading it carefully to cover all the corners. Slide the pan into the oven and bake for 30–35 minutes, until the top turns golden with a slightly firm touch. The kitchen will smell amazing by now!
Step 8: Cool and Slice
Let the bars cool completely in the pan, allowing the marshmallow and chocolate layers to set. For the cleanest, prettiest slices, chill the pan for about 30 minutes before cutting. Then, lift out and slice into 24 Mud Hen Bars—get ready for rave reviews!
How to Serve Mud Hen Bars
Garnishes
Mud Hen Bars are eye-catching on their own, but you can dress them up even more. Try a dusting of powdered sugar, a drizzle of melted chocolate, or a few more toasted nuts on top for an extra-special touch. A dollop of whipped cream takes them to dreamy new heights.
Side Dishes
Pair your Mud Hen Bars with a scoop of vanilla ice cream, a tall glass of cold milk, or a creamy cup of coffee for a truly blissful dessert experience. Their classic sweet flavor also makes them a perfect addition to a Southern dessert platter alongside pecan pie or blondies.
Creative Ways to Present
For parties, cut bars into smaller bites and serve them in cupcake liners, or stack them high on a beautiful dessert tray. Wrap a few individually in parchment paper and ribbon for the sweetest homemade gifts—Mud Hen Bars are always a hit at bake sales and picnics!
Make Ahead and Storage
Storing Leftovers
Place any leftover Mud Hen Bars in an airtight container at room temperature for up to 4 days. If your kitchen gets warm, store them in the fridge to keep the meringue layer fresh and crisp.
Freezing
Mud Hen Bars freeze beautifully! Simply wrap individual bars tightly in plastic wrap and pop them in a zip-top freezer bag. They’ll keep for up to 2 months—let them thaw at room temperature before serving.
Reheating
If you love your Mud Hen Bars a little warm and melty, microwave individual bars for 8-10 seconds. This brings out the gooiness of the marshmallow and chocolate layers and makes them taste freshly baked.
FAQs
Can I substitute walnuts or almonds for pecans?
Absolutely! While pecans add classic Southern flavor, walnuts or almonds will be just as delicious and bring their own unique crunch to your Mud Hen Bars. Feel free to use your favorite nut, or leave them out entirely for a nut-free version.
Why is my meringue layer not crisp?
If the meringue layer on your Mud Hen Bars is soft, it could be due to under-baking or humidity in your kitchen. Bake until the top is golden and just set, and let the bars cool completely before slicing for the best crackly finish.
Can I double the recipe for a crowd?
You sure can! If you’re making Mud Hen Bars for a party, double the recipe and divide between two pans for even baking. Keep an eye on the bake time; they may need a few extra minutes.
Are Mud Hen Bars gluten-free?
Traditional Mud Hen Bars use all-purpose flour, which contains gluten. However, you can try swapping a gluten-free all-purpose flour blend cup-for-cup for a gluten-free batch; just know the texture may vary a bit.
Do I have to line the pan with parchment paper?
Lining your pan with parchment paper makes removing and slicing the bars so much easier, especially with the sticky marshmallow layer. Greasing the pan can work in a pinch, but parchment guarantees a mess-free lift every time.
Final Thoughts
Mud Hen Bars are the kind of dessert that feels like a little slice of home. Once you taste those layers—chewy, gooey, and crisp all at once—you’ll understand why this recipe is always requested at potlucks and family gatherings.
