Ingredients
- Graham Crackers: These iconic crackers form the foundation of the dessert, providing that unmistakable crunch and sweetness that defines a traditional s’more. You’ll need 7-8 full sheets of graham crackers to create a sturdy, sweet base for the bars.
- Unsalted Butter: The butter in this recipe brings a rich, creamy flavor and helps create that soft, chewy texture in the cookie dough. Be sure to use room temperature butter so that it mixes easily with the sugars.
- Granulated Sugar & Light Brown Sugar: A combination of both sugars creates a perfect balance of sweetness and moisture in the cookie dough. The brown sugar also adds a touch of molasses flavor that enhances the overall taste of the bars.
- Eggs: Eggs help bind the ingredients together and provide structure to the cookie bars. They also contribute to the tender texture.
- Vanilla Extract: A classic addition to many baked goods, vanilla extract infuses the dough with a warm, aromatic flavor that complements the sweetness of the other ingredients.
- All-Purpose Flour: The flour is the primary structure of the cookie dough. It helps create a chewy, soft texture while allowing the other ingredients to shine.
- Baking Soda & Salt: The baking soda provides lift to the cookie dough, helping it rise slightly while baking. The salt, while subtle, enhances the sweetness and balances the richness of the butter and sugar.
- Semi-Sweet Chocolate Chips: These chocolate chips melt beautifully in the dough, giving the cookie bars a rich, gooey texture with pockets of melted chocolate in every bite.
- Mini Marshmallows: The marshmallows add a chewy, gooey sweetness that mimics the classic s’mores experience. They toast and melt slightly in the oven, making for a perfect contrast against the crunchy graham cracker base.
- Hershey’s Milk Chocolate Bars: The final touch! The broken pieces of milk chocolate bars are scattered on top of the baked bars, providing a rich, melty layer of chocolate that melts into the cookie dough for an extra indulgent experience.
Instructions
- Preheat the Oven: Begin by preheating your oven to 375°F. This ensures that your bars bake evenly and achieve that perfect golden-brown color.
- Prepare the Pan: Line a 13×9-inch baking pan with parchment paper, leaving a 2-inch overhang on the sides. This makes it easier to lift the bars out of the pan once they’re done, ensuring a clean cut and easy removal.
- Graham Cracker Layer: Break the graham crackers into sections as needed and arrange them in a single layer to cover the bottom of the prepared pan. This creates the perfect foundation for the cookie dough and gives the bars that classic s’mores base.
- Make the Cookie Dough: In the bowl of an electric mixer, cream together the room-temperature butter and both granulated and brown sugars. Beat until the mixture is light and fluffy. Add in the eggs and vanilla extract, mixing until well combined. In a separate bowl, whisk together the flour, salt, and baking soda. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Gently fold in the chocolate chips and mini marshmallows, making sure they’re evenly distributed throughout the dough.
- Assemble the Bars: Spread the cookie dough evenly over the graham cracker layer in the pan, pressing it down gently to make sure it’s evenly distributed. If you like, you can top the dough with additional mini marshmallows for a little extra marshmallowy goodness.
- Bake the Bars: Place the pan in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. Keep an eye on the bars as they bake, and if the cookie dough starts to brown too quickly on top, you can cover it loosely with aluminum foil to prevent overbaking.
- Add the Chocolate: Once the bars are done baking, remove them from the oven and immediately place the broken pieces of Hershey’s chocolate bars on top of the warm cookie bars. Allow the chocolate to soften and melt into the bars.
- Cool and Serve: Let the bars cool for about 20-30 minutes, allowing the chocolate to set slightly but still remain gooey. Carefully lift the parchment paper overhang to remove the bars from the pan, then cut into 24 squares for easy serving.
Notes
- Room Temperature Ingredients: Make sure your butter and eggs are at room temperature before mixing. This ensures the ingredients combine easily and result in a smooth, uniform dough.
- Use a Metal Pan: While glass pans work fine, using a metal or aluminum pan tends to yield more even results, especially for gooey, slightly underbaked bars.
- Storage: S’mores Cookie Bars can be stored at room temperature in an airtight container for up to 3-4 days. If you prefer a firmer chocolate layer, refrigerate the bars to help the chocolate set up completely.
- Freezing: These bars freeze wonderfully! Simply wrap individual squares in plastic wrap, then place them in a freezer bag or airtight container. They’ll keep for up to 3 months in the freezer. To enjoy, simply thaw them at room temperature or pop them in the microwave for a few seconds to melt the chocolate again.
