S’mores Magic Cookie Bars Ingredients For the Crust Graham Crackers – They provide the base layer and add a crunchy texture. Consider using digestive biscuits as a gluten-free alternative. Unsalted Butter (6 TBSP) – Adds richness and binds the crust together. Coconut oil can be used for a dairy-free version. Granulated Sugar (2 TBSP) – Sweetens the crust. Brown sugar can create a deeper flavor profile. For the Cookie Layer Unsalted Butter (1/2 cup) – Binds the cookie layer together and adds a creamy richness. Substitute with coconut oil for a dairy-free option. Granulated Sugar (3/4 cup) – Sweetens the cookie layer. For a slightly different flavor, try using brown sugar instead. All-Purpose Flour (1 1/4 cup) – Provides structure to the cookies. Use a gluten-free flour blend if needed. Salt (1/4 tsp) – Enhances the overall flavor. For a gourmet touch, consider using sea salt. Baking Powder (1/4 tsp) – Helps with leavening the cookie layer. Make sure it’s fresh for optimal results. Vanilla Extract (1 tsp) – Adds a warm, aromatic flavor. Opt for pure vanilla extract for better taste. Large Egg (1) – Acts as a binder for the ingredients. You can replace it with flaxseed meal (1 tbsp flax meal + 2.5 tbsp water) for vegan options. Mix-Ins Milk Chocolate Chips (1 cup) – Adds sweetness and that classic chocolatey goodness. For a richer taste, substitute with dark chocolate chips. Mini Marshmallows (1 cup) – Provide the traditional s’mores flavor and a chewy texture. Larger marshmallows can be used if desired. Sweetened Condensed Milk (3/4 cup) – Drizzled on top for extra sweetness and moisture. Look for dairy-free condensed milk options for an allergy-friendly recipe. Get ready to indulge in the delightful layers of S’mores Magic Cookie Bars! Step‑by‑Step Instructions for S’mores Magic Cookie Bars Step 1: Preheat and Prepare Begin by preheating your oven to 350°F (175°C). While it warms up, take a 9×13 inch baking dish and lightly grease it with cooking spray or butter to prevent sticking. This step sets the foundation for your S’mores Magic Cookie Bars, ensuring a delightful golden crust once baked. Step 2: Make the Crust In a mixing bowl, combine the crushed graham crackers, melted butter, and granulated sugar. Stir until the mixture is well combined and resembles wet sand. Once ready, firmly press this mixture into the bottom of the prepared baking dish, creating an even layer that will act as a crunchy base for your magical cookie bars. Step 3: Mix Dry Ingredients In a separate bowl, whisk together the all-purpose flour, salt, and baking powder until evenly combined. This is a crucial step to incorporate air and ensure your cookie layer rises beautifully. Once mixed, set the bowl aside as you proceed to the next step for your S’mores Magic Cookie Bars. Step 4: Cream Butter and Sugar In a large mixing bowl, beat together the unsalted butter and granulated sugar using an electric mixer on medium speed. Continue mixing until the mixture is light and fluffy, about 3-5 minutes. Then, add the egg and vanilla extract, ensuring everything is well incorporated for a rich and flavorful cookie layer. Step 5: Combine Wet and Dry Mixtures Gradually add the flour mixture to the creamy butter mixture, mixing on low speed just until a thick dough forms. Be careful not to overmix, as this can make your bars tough. The dough should be slightly sticky yet manageable, ready to spread over the graham cracker crust in the baking dish. Step 6: Spread the Dough Spoon the thick dough over the graham cracker crust, spreading it gently with a spatula. It may not cover every part of the crust completely, and that’s okay! Just ensure an even layer, which will harmoniously meld with the crust during baking, creating the luscious texture of your S’mores Magic Cookie Bars. Step 7: Add Toppings Sprinkle the mini marshmallows and milk chocolate chips evenly over the dough. Follow this by drizzling the sweetened condensed milk generously on top. Each element adds layers of flavor and texture, making your bars delectable and irresistible. This step is crucial as it captures the essence of traditional s’mores. Step 8: Bake Until Golden Place the baking dish in the preheated oven and bake for 22-27 minutes, or until the edges are golden brown and the marshmallows are toasty. Keep an eye on the bars as they bake; the visual cues will help you determine when they’re perfectly done, delivering that ideal gooey and crunchy balance. Step 9: Cool and Slice Once baked, remove the pan from the oven and allow the S’mores Magic Cookie Bars to cool in the dish at room temperature. For best results, let them cool completely before slicing into squares. This step is essential for achieving the right texture, ensuring that they cut cleanly and hold their shape when served. What to Serve with S’mores Magic Cookie Bars As the rich aroma of chocolate and toasted marshmallows wafts through your kitchen, it’s time to elevate these delightful bars into a complete dessert experience. Vanilla Ice Cream: The classic pairing of cold, creamy vanilla ice cream wonderfully contrasts with the warm, gooey bars, creating a delightful temperature experience. Whipped Cream: A dollop of fluffy whipped cream adds a lightness that balances the richness of S’mores Magic Cookie Bars, perfect for satisfying sweet cravings. Fresh Berries: Juicy strawberries or raspberries bring a burst of freshness that cuts through the sweetness, enhancing the overall flavor profile. Chocolate Sauce: Drizzling extra chocolate sauce on top creates a luscious layer of indulgence, making each bite even more decadent and inviting. Coffee or Espresso: A warm cup of strong coffee enhances the chocolatey goodness, making this pairing an excellent choice for adults looking for a perfect dessert moment. Nutty Trail Mix: For a crunchy contrast, serve alongside a homemade nutty trail mix. Its texture and flavor will harmonize well with the soft, chewy bars. Imagine savoring these S’mores Magic Cookie Bars with any of these delightful accompaniments, transforming a simple treat into a memorable dessert experience! Expert Tips for S’mores Magic Cookie Bars Cool Thoroughly: Allow the bars to cool completely before cutting; this helps them set properly and maintain their structure. Prevent Crust Crumbling: If the graham cracker crust is crumbling, gently bake it for a few minutes before adding the cookie layer to firm it up. Watch Your Oven: Keep an eye on the baking time; ovens can vary, so check your S’mores Magic Cookie Bars around the 22-minute mark for a perfect golden finish. Avoid Overmixing: When incorporating the flour mixture, mix just until combined; overmixing can create tough bars rather than soft, chewy ones. Customize with Toppings: Feel free to experiment by adding nuts or different flavored chips to personalize your S’mores Magic Cookie Bars for your taste. Make Ahead Options These S’mores Magic Cookie Bars are perfect for meal prep, allowing you to enjoy indulgent desserts with less hassle! You can prepare the crust and cookie layers up to 24 hours in advance; simply store them separately in the refrigerator. For the crust, press the graham cracker mixture into the baking dish but skip the baking step—this way, it stays fresh. When you’re ready to serve, spread the cookie layer over the chilled crust, add marshmallows and chocolate chips, then bake as directed. This approach delivers the same deliciousness, while saving you valuable time on busy weeknights! S’mores Magic Cookie Bars Variations Let your creativity shine as you customize these treats to fit your taste buds and dietary needs! Gluten-Free: Use gluten-free graham crackers or a blend of gluten-free flour for the crust and cookie layer without sacrificing flavor. Nutty Delight: Fold in chopped pecans or walnuts to add a delightful crunch and a boost of flavor. The added texture will complement the gooey marshmallows beautifully! Dairy-Free: Swap butter for coconut oil and use dairy-free chocolate chips and sweetened condensed milk to keep all the deliciousness without the dairy. Peanut Butter Swirl: Substitute half the butter with creamy or chunky peanut butter. This adds a nutty richness that pairs perfectly with chocolate and marshmallows. Different Flavor Chips: Experiment with butterscotch, white chocolate, or even mint chips for a brand new twist on the classic s’mores flavors. Add a Touch of Spice: Elevate the flavor by incorporating a pinch of cinnamon or a dash of cayenne pepper. These spices add warmth and a hint of excitement. Bite-Sized Treats: Instead of a large bar, press the mixture into mini muffin tins for portable, bite-sized cookie bars that are perfect for sharing at gatherings.

Reheating: To enjoy these bars warm, pop them in the microwave for about 10-15 seconds. This will make the chocolate gooey and the marshmallows soft again! S’mores Magic Cookie Bars Recipe FAQs How do I choose the right graham crackers for my S’mores Magic Cookie Bars? Absolutely! Look for graham crackers that are fresh and not broken.
