How to Make Mud Hen Bars
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This step is crucial because it ensures that your bars bake evenly and rise beautifully.
Step 2: Prepare Your Baking Pan
Lightly spray a 9×13-inch baking pan with cooking spray. This will help prevent sticking and make it easy to lift out the bars once they’re cool.
Step 3: Cream Together the Base Ingredients
In a large bowl, cream together the room temperature butter, granulated sugar, one whole egg plus two yolks, and vanilla until smooth. This process incorporates air into the mixture, creating that lovely light texture we want in our dessert.
Step 4: Combine Dry Ingredients
Next, add in the flour, baking powder, and salt. Mix until just combined; over-mixing can lead to tough bars. Once mixed, spread this batter evenly into your prepared pan.
Step 5: Add Chocolate Chips and Marshmallows
Sprinkle the mini vegan marshmallows and semi-sweet chocolate chips over the top of the batter. These will melt during baking, creating delightful pockets of gooey goodness throughout.
Step 6: Make the Meringue Topping
In a clean mixing bowl using a whisk attachment on your mixer, beat the two remaining egg whites until stiff peaks form—this usually takes about two minutes on high speed. The stiff peaks mean that your meringue will hold its shape nicely when baked.
Step 7: Fold in Brown Sugar
Gently fold in the packed light brown sugar into the whipped egg whites until combined without lumps. This step adds sweetness and helps create that beautiful golden topping.
Step 8: Spread Over Chocolate Chips & Marshmallows
Carefully spread this meringue mixture over your chocolate chips and marshmallows. It might look like too much at first, but it’s just right!
Step 9: Bake Until Golden Brown
Bake in your preheated oven for about 30-35 minutes or until the top is golden brown. The aroma wafting through your kitchen will be irresistible!
Step 10: Cool Before Cutting
Once baked, allow your Mud Hen Bars to cool completely before cutting them into squares. This helps them set properly so they hold their shape when served.
Now you have a wonderful batch of Mud Hen Bars ready to enjoy! Perfect for sharing or savoring all by yourself—happy baking!
Pro Tips for Making Mud Hen Bars
Making Mud Hen Bars is a delightful experience, and with these tips, you can elevate your baking game!
- Use room temperature ingredients: Ensuring that your butter and eggs are at room temperature helps them mix more smoothly, resulting in a better texture for your bars.
- Don’t skip the cooling time: Allowing the bars to cool completely before cutting lets the meringue set properly, making it easier to achieve neat squares without crumbling.
- Experiment with chocolate types: While semi-sweet chocolate chips are classic, trying dark or even white vegan chocolate can add a unique twist to the flavor profile of your bars.
- Customize your toppings: Feel free to add nuts or dried fruits along with the marshmallows to give an extra crunch and depth of flavor that complements the sweetness of the bars.
- Store properly: Keep any leftovers in an airtight container at room temperature for up to 3 days. This keeps them fresh and chewy.
