Step‑by‑Step Instructions for Gooey S’Mores Bars
Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). Take a 9×13-inch baking pan and line it with aluminum foil, leaving a 2-inch overhang on the sides for easy removal. Lightly spray the foil with nonstick cooking spray to ensure the S’Mores Bars lift out easily once baked.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together 1½ cups of all-purpose flour, 1 cup of graham cracker crumbs, 1 teaspoon of baking powder, and ½ teaspoon of salt. This combination forms the foundation of your bars, providing structure and flavor. Be sure to mix until well combined and set aside for the next step.
Step 3: Cream the Butter and Sugar
In a large mixing bowl, beat together ½ cup of room-temperature unsalted butter and 1 cup of light brown sugar using an electric mixer until the mixture is light and fluffy, about 2 minutes. This creates a rich base for your S’Mores Bars. Next, add in 2 beaten large eggs, mixing well until fully incorporated.
Step 4: Combine Wet and Dry Mixtures
Gradually add the dry flour mixture to the creamed butter and sugar, mixing on low speed until just combined. Be careful not to overmix, as you want a tender bar texture. The batter will be thick and slightly sticky, perfect for your S’Mores Bars.
Step 5: Press Half of the Dough into the Pan
Divide the dough in half, and with clean hands, press half of the mixture evenly into the prepared baking pan. This will form the crust for your bars. Ensure it’s packed down well, making the surface even and ready for the toppings that will create that classic S’Mores taste.
Step 6: Add Marshmallow and Chocolate
Spread 1 cup of marshmallow topping evenly over the crust, allowing it to fully cover the surface. Next, sprinkle 1 cup of milk chocolate chips on top of the marshmallow layer. The combination of these ingredients will create the gooey, sweet filling of your S’Mores Bars.
Step 7: Crumble the Remaining Dough
Take the remaining half of the dough and crumble it in small clumps over the marshmallow and chocolate layers. Ensure some of the chocolate and marshmallow are left exposed for that delicious gooey look. This will help create a perfect balance of textures in your S’Mores Bars.
Step 8: Bake to Perfection
Place the baking pan in your preheated oven and bake for 30 to 35 minutes, or until the top turns a lovely golden brown. The bars should be set in the center but still soft to the touch. Keep an eye on them to avoid overbaking and losing that delicious gooeyness.
Step 9: Cool and Slice
Once baked, remove the pan from the oven and let it cool on a wire rack. Allow the S’Mores Bars to cool completely in the pan before lifting them out using the foil overhang. Slice into squares and savor the delicious flavors of this irresistible treat!
