Step‑by‑Step Instructions for S’mores Cookie Bars
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms up, grease a 9×13 inch baking pan with cooking spray or line it with parchment paper, ensuring the edges hang over for easy removal later. This preparation step will make it easier to remove your delicious S’mores Cookie Bars after baking.
Step 2: Cream the Butters and Sugars
In a large mixing bowl, combine the softened unsalted butter, brown sugar, and granulated sugar. Using a hand or stand mixer, cream the mixture together on medium speed until it becomes light, fluffy, and pale—this should take about 2-3 minutes. This step is essential for creating a tender cookie base for your S’mores Cookie Bars.
Step 3: Add the Wet Ingredients
Next, beat in the large eggs, one at a time, ensuring each is fully incorporated before adding the next. Then, stir in the vanilla extract until combined. This mixture should look smooth and glossy, which is a good sign that your batter is coming together beautifully for those chewy centers.
Step 4: Mix the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add this dry mixture to the butter mixture, mixing gently until just combined. Be careful not to overmix; you want to maintain that soft, gooey texture that makes these S’mores Cookie Bars irresistible.
Step 5: Fold in Graham Crackers and Chocolate
Now, fold in the graham cracker crumbs and half of the chocolate chips into the dough using a rubber spatula. Mix until everything is evenly distributed, creating a rich cookie dough infused with the classic flavors of S’mores—sweet and buttery, with delightful crunch.
Step 6: Layer the Cookie Dough
Press half of the cookie dough mixture into the prepared baking pan evenly. Then, sprinkle the mini marshmallows over the base layer, spreading them out evenly. Carefully place the remaining half of the cookie dough on top, covering the marshmallows completely. This creates that luscious, gooey center we all love.
Step 7: Add Extra Toppings
Before baking, sprinkle additional chocolate chips and mini marshmallows on top of the layered cookie dough. This not only adds to the visual appeal but also creates an even more gooey and melty topping, ensuring every bite of your S’mores Cookie Bars is packed with flavor.
Step 8: Bake Until Golden
Place the baking pan in the preheated oven and bake for 25-30 minutes. Watch for the edges turning golden brown and a slight puffing of the center. A toothpick inserted in the middle should come out clean or with just a few moist crumbs—this indicates that your S’mores Cookie Bars are perfectly baked!
Step 9: Cool and Cut
Once baked, remove the pan from the oven and let the S’mores Cookie Bars cool in the pan for about 10 minutes. Use the parchment overhang to lift them out and transfer to a wire rack for complete cooling. Once cooled completely, slice them into squares for that perfect handheld treat, ready for sharing!
Make Ahead Options
These S’mores Cookie Bars are perfect for meal prep aficionados! You can prepare the cookie dough up to 24 hours in advance. To do this, simply mix the ingredients as per the instructions and store the unbaked dough in an airtight container in the refrigerator. This not only saves you time but also allows the flavors to meld beautifully. If you prefer, you can layer the dough and mini marshmallows in the baking pan, cover with plastic wrap, and refrigerate for up to 3 days before baking. When ready to enjoy, simply preheat your oven and bake directly from the fridge, adding a few extra minutes to the baking time for those perfectly chewy S’mores Cookie Bars just like homemade!
