Step‑by‑Step Instructions for S'mores Magic Cookie Bars
Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). While that’s heating up, grab a 9x13-inch baking pan and lightly spray it with cooking spray to prevent sticking. This is an essential step for your S'mores Magic Cookie Bars, ensuring they come out effortlessly from the pan once baked.
Step 2: Make the Crust
In a mixing bowl, combine crushed graham cracker sheets, melted unsalted butter, and granulated sugar until the mixture resembles wet sand. Press this mixture firmly and evenly into the bottom of the prepared pan using your fingers or the bottom of a measuring cup. This crust will provide a sturdy base for your delicious S'mores Magic Cookie Bars.
Step 3: Prepare the Cookie Layer
In a separate bowl, whisk together the all-purpose flour, baking powder, and salt to ensure even distribution of the leavening agent. Then, cream together unsalted butter and granulated sugar in another bowl until fluffy, about 2-3 minutes. Add a large egg and vanilla extract, mixing until well incorporated. Gradually blend in the flour mixture until just combined to avoid overmixing, which is key for a lighter texture in your cookie layer.
Step 4: Assemble the Bars
Spread the prepared cookie layer evenly over the graham cracker crust in the baking pan, smoothing it out with a spatula. Aim for an even coverage to ensure every bite of your S'mores Magic Cookie Bars is deliciously balanced. This simple assembly is the transition from base to the star of the show, the toppings!
Step 5: Add Toppings
Sprinkle milk chocolate chips and mini marshmallows generously over the cookie layer, ensuring they are evenly distributed. Finally, drizzle sweetened condensed milk over the top to bind all the flavors together and add that gooey aspect that makes these S'mores Magic Cookie Bars irresistible. This step will also create a beautiful glaze when baked.
Step 6: Bake the Bars
Place the pan in the preheated oven and bake for 22-27 minutes. Keep an eye on the edges; they should turn golden brown while the center remains slightly soft. This is crucial for achieving that perfect balance between chewy and gooey texture in your S'mores Magic Cookie Bars.
Step 7: Cool and Slice
Once baked, remove the pan from the oven and let it cool in the pan for at least 30 minutes. This cooling period is essential for the bars to firm up, making it easier to slice into squares. Patience will pay off, as cutting them too soon could lead to a messy serving of your delightful S'mores Magic Cookie Bars.
Make Ahead Options
These S'mores Magic Cookie Bars are perfect for meal prep enthusiasts! You can prepare the crust and cookie layer up to 24 hours in advance. Simply complete steps 1 through 3 of the recipe, cover them tightly with plastic wrap, and refrigerate until you’re ready to bake. This not only saves you time on busy weeknights but ensures the freshness of your dessert. When it’s time to finish, simply proceed with assembling the layers (step 4) and baking as instructed. To maintain the bars' gooey texture and flavor, make sure to cool them completely before slicing. With this make-ahead strategy, you’ll have a delightful treat ready with minimal last-minute effort!
Expert Tips for S'mores Magic Cookie Bars
