How to Make S’mores Cookie Bars
Follow these simple steps to prepare this delicious S’mores Cookie Bars:
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper or coat it with nonstick spray to ensure easy removal.
Step 2: Cream the Butters and Sugars
In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar until the mixture is light and fluffy, which should take about three minutes. This process is crucial for a soft, chewy cookie bar.
Step 3: Incorporate Eggs and Vanilla
Add the eggs to the mixture one at a time, beating well after each addition. Then stir in the vanilla extract, letting the sweet scent envelop your kitchen.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, graham cracker crumbs, baking soda, and salt. Gradually mix this dry mixture into the wet ingredients until just combined. Avoid overmixing, or you might end up with tough bars.
Step 5: Build Your Layers
Press two-thirds of your dough into the bottom of the prepared baking dish. Layer the chocolate chips evenly over the dough. Carefully spread the marshmallow fluff on top, creating a deliciously gooey layer.
Step 6: Top It Off and Bake
Crumble the remaining cookie dough over the marshmallow fluff, ensuring some gooey goodness peeks through. Bake the bars for 25–28 minutes or until they are golden brown and set. The anticipation will have your mouth watering!
After baking, let the S’mores Cookie Bars cool completely in the pan before slicing into squares. Serve them up with a scoop of vanilla ice cream or just enjoy them as they are for a truly nostalgic experience.
In conclusion, S’mores Cookie Bars bring a delightful twist to the traditional s’mores we love, making them easy to share with friends and family. They are perfect for any occasion, be it a cozy night in or a summer BBQ. So grab those ingredients, unleash your inner chef, and prepare for some delicious, gooey fun!
