Step‑by‑Step Instructions for S'mores Magic Cookie Bars
Step 1: Preheat the Oven
Begin your baking journey by preheating the oven to 350°F (175°C). While waiting, grab a 9x13 inch baking pan and generously coat it with cooking spray to ensure your S'mores Magic Cookie Bars will come out easily later on. The pan should be ready by the time you've assembled the crust.
Step 2: Make the Crust
In a mixing bowl, combine crushed graham cracker sheets, melted unsalted butter, and granulated sugar. Stir until the mixture resembles wet sand, ensuring all crumbs are moistened. With a firm hand, press this mixture evenly into the bottom of your prepared pan. This will provide a sturdy base for your delicious cookie bars, so make sure it’s compact and even.
Step 3: Prepare the Cookie Layer
In another bowl, whisk together all-purpose flour, baking powder, and salt until well combined. In a separate mixing bowl, cream together softened butter and granulated sugar until the mixture is light and fluffy, about 2-3 minutes. Add in the egg and vanilla extract, mixing until fully incorporated. This creamy mixture will create the soft, delectable layer atop your graham cracker crust.
Step 4: Combine Mixtures
Gently fold the dry flour mixture into the creamed butter mixture, mixing until just combined. Be careful not to overmix, as this can affect the texture. This is the cookie layer that will sit on top of your graham cracker crust, so spread it evenly across the prepared base. Aim for a smooth finish to ensure every bite of your S'mores Magic Cookie Bars is delightful.
Step 5: Add Toppings
Now it’s time for the fun part—adding the toppings! Sprinkle a generous amount of milk chocolate chips and mini marshmallows over the cookie layer. This combination will melt beautifully during baking. Lastly, drizzle sweetened condensed milk evenly over the top. This will bind the layers together and create that signature gooeyness associated with S'mores.
Step 6: Bake the Bars
Place the assembled bars 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. Baking times may vary depending on your oven, so check for that delicious golden hue that signifies your S'mores Magic Cookie Bars are ready to be taken out.
Step 7: Cool and Slice
Once out of the oven, allow your S'mores Magic Cookie Bars to cool in the pan for about 20-30 minutes. For best results, let them cool overnight if you can resist the temptation! When they are cool enough to handle, slice them into squares or rectangles, and marvel at the delightful layers that evoke those cherished campfire memories.

Expert Tips for S'mores Magic Cookie Bars
- Pre-bake for Stability: Pre-baking the graham cracker crust for 5 minutes creates a firmer base, preventing sogginess once you add the cookie layer.
- Cooling Time Matters: Allow sufficient cooling time before slicing to maintain the bars’ shape and enhance flavors. Rushing this step often leads to crumbly bars!
- Check Ingredient Freshness: Ensure your baking powder is fresh to guarantee a good rise in the cookie layer. Without it, your bars might turn out dense and flat.
- Mix-in Options: Feel free to add your favorite mix-ins like nuts or different chocolate types; just be cautious not to overcrowd the mixture, which can affect baking.
- Oven Variations: Baking times can vary depending on the oven. Start checking at the lower end of the baking range to avoid overbaking your S'mores Magic Cookie Bars.
Make Ahead Options
These S'mores Magic Cookie Bars are perfect for meal prep, making them a fantastic choice for busy weeknights or gatherings! You can prepare the crust (graham cracker mixture) and the cookie layer up to 24 hours in advance. Simply assemble both layers in your baking pan, cover tightly with plastic wrap, and refrigerate until you’re ready to bake. When you're set to serve, top with chocolate chips, mini marshmallows, and drizzle with sweetened condensed milk before baking. This not only saves time but also ensures your bars remain just as delicious, with that gooey texture that everyone loves. Enjoy the convenience of preparing ahead and savor the joy of freshly baked treats without the last-minute rush!
