Cooking Instructions for S’mores Cookie Bars

Let’s get started on making these delicious S’mores Cookie Bars. Follow these steps for a perfect outcome. You’ll see how easy it is to create this treat!
Preheat your oven to 350 degrees F (165 degrees C). Getting the oven ready is crucial for ensuring an even bake. This temperature is perfect for achieving that golden-brown top.
If you haven’t already, place the frozen mini marshmallows in the freezer now. This will help them keep their shape as the bars bake.
Spray a 9×13 inch baking dish with cooking spray to prevent sticking. Alternatively, you could line it with parchment paper for easier removal.
In a medium bowl, combine the graham cracker crumbs, granulated sugar, and melted butter. Mix until fully combined, creating a moist crumb mixture. Press this mixture evenly into the bottom of your prepared baking dish. This will form the crust, so make sure it’s packed tightly.
In another bowl, sift together the all-purpose flour, baking soda, and salt. Set this aside as you prepare the wet ingredients.
In a large bowl, cream together the melted butter (make sure it’s mostly cooled), brown sugar, and remaining granulated sugar until well blended. You want this mixture to be light and fluffy, which indicates that air has been incorporated.
Beat in the vanilla, egg, and egg yolk until the mixture is light and creamy. This step is essential for adding richness and flavor to your bars.
Now, gradually mix in the sifted ingredients until just blended. Be careful not to overmix; you want to keep the bars soft and chewy.
Fold in the semi-sweet chocolate chips and 1 cup of the frozen mini marshmallows. The chocolate should be evenly distributed for that delightful gooeyness.
Scoop the dough over the graham cracker crust, gently pressing it into an even layer. Don’t worry if it doesn’t cover the pan completely; it will spread as it bakes.
Sprinkle the remaining ½ cup of mini marshmallows on top, pressing them in slightly to adhere. This will create a lovely toasted top when baked.
Bake for 18 to 25 minutes, or until the top begins to get golden brown. Make sure the center is set and not jiggly, as they will firm up during cooling.
Once baked, remove the pan from the oven and let it sit for about 5 minutes. Carefully place the broken pieces of Hershey chocolate bars on top. The residual heat will melt the chocolate slightly.
Allow the bars to cool completely before cutting them into squares. Patience is key here; the bars will be easier to cut when fully cooled.
Things Worth Knowing
- Cool Completely: Always let your bars cool completely before cutting. This ensures cleaner edges and prevents them from falling apart.
- Don’t Overbake: Keep a close eye on your bars as they bake. Overbaking can lead to dry cookie bars, whereas underbaking leaves a gooey center.
- Storage: These bars can be stored in an airtight container at room temperature for up to a week. For longer storage, consider refrigerating them.
- Mix-ins: Feel free to add nuts, different types of chocolate, or even peanut butter chips to the mix for a unique twist!
- Serving: These bars are delicious warm, but they can also be enjoyed cold. Try serving them with a scoop of ice cream for an indulgent treat!
Change It Up

If you’re looking to experiment with your S’mores Cookie Bars, here are some tips to add a twist to your creation:
- Flavor Variations: You can mix in different flavors of chocolate chips, such as milk chocolate or white chocolate, to keep it interesting.
- Nutty Addition: Consider adding some chopped nuts, like pecans or walnuts, for a crunchy texture that complements the softness of the bars.
- Seasonal Toppings: Try adding seasonal toppings like crushed peppermint for winter or fresh berries for summer.
- Different Bases: Instead of using purely graham cracker crumbs, consider mixing in some crushed cookies, like Oreos, for a fun spin on the crust.
- Chocolate Variations: Use different brands or types of chocolate bars for the topping to give your bars a unique flavor profile.
- Extra Layers: For an extra indulgence, spread a layer of peanut butter or Nutella on the graham cracker base before adding the cookie dough!
How to Serve S’mores Cookie Bars
