IngredientsFor the Graham Cracker Base1½ cups graham cracker crumbs½ cup melted butterFor the Cookie Layer1 cup all-purpose flour¾ cup brown sugar1 egg1 teaspoon vanilla extractFor the Filling and Topping1 cup chocolate chips1½ cups mini marshmallows
Equipment Needed8x8-inch baking panMixing bowlsMeasuring cups and spoonsRubber spatulaParchment paperWire cooling rack
Step 1: Prepare Your PanPreheat your oven to 350°F (175°C).Line an 8×8-inch baking pan with parchment paper, allowing some overhang on the sides. This makes removing the bars much easier after baking.Lightly grease the parchment paper with cooking spray or butter to prevent sticking.
Step 2: Make the Graham Cracker CrustIn a medium bowl, combine the graham cracker crumbs and melted butter.Mix until all crumbs are evenly coated and resemble wet sand. The mixture should hold together when pressed between your fingers.Transfer the mixture to the prepared baking pan and press firmly into an even layer across the bottom.Use the back of a measuring cup or glass to compact the crust tightly.Bake for 8 minutes.Remove from the oven and allow it to cool slightly while preparing the cookie dough.
Step 3: Prepare the Cookie DoughIn a mixing bowl, combine the brown sugar, egg, and vanilla extract.Whisk until smooth and creamy.Add the flour and stir until a soft dough forms.The dough will be thick but should still be easy to spread.Avoid overmixing, as this can make the bars tough instead of tender and chewy.
Step 4: Assemble the LayersSprinkle the chocolate chips evenly over the slightly cooled graham cracker crust.Spread them out so every bite gets plenty of chocolate.Next, carefully spread the cookie dough over the chocolate chips.Because the dough is thick, drop spoonfuls across the surface first, then gently spread with a spatula.Don’t worry if it isn’t perfectly smooth. It will spread as it bakes.
Step 5: Bake the Cookie LayerPlace the pan into the preheated oven.Bake for 18 to 22 minutes, or until the cookie layer appears lightly golden around the edges.The center may still seem slightly soft, which is perfect because it will continue cooking after removal from the oven.
Step 6: Add the MarshmallowsRemove the bars from the oven.Immediately sprinkle the mini marshmallows evenly over the hot cookie layer.Return the pan to the oven for 3 to 5 minutes.Watch carefully as the marshmallows puff up and become lightly golden.For an extra campfire-style appearance, switch the oven to broil during the final minute. Keep a close eye on them because marshmallows can brown very quickly.
Step 7: Cool CompletelyRemove the bars from the oven.Allow them to cool in the pan for at least 30 minutes.Then transfer them to a wire rack to cool completely.This step is important because the chocolate needs time to set slightly, making the bars easier to slice.If you prefer extra gooey bars, enjoy them while still slightly warm.
Step 8: Slice and ServeUsing the parchment paper overhang, lift the bars from the pan.Place them on a cutting board.Cut into 9 large bars or 16 smaller squares.Serve as they are or pair with:Vanilla ice creamHot chocolateCold milkCoffeeChocolate sauce drizzle
Tips for Perfect S’mores Cookie BarsUse Fresh MarshmallowsFresh marshmallows melt and toast much better than older ones that have become dry or stale.Don’t OverbakeThe cookie layer should remain slightly soft when removed from the oven. Overbaking can result in dry bars.Line the PanParchment paper makes removal simple and helps maintain clean edges.Let Them CoolCooling helps the layers set properly and makes slicing easier.Toast CarefullyIf using the broiler, never walk away. Marshmallows can burn in seconds.
