Detailed Recipe Steps with Practical Tips
- Preheat the oven: Begin by preheating your oven to 350°F (175°C). This step is crucial as it ensures even baking. While the oven heats up, you can prepare your baking pan.
- Prepare the baking pan: Grease a 9×13 inch baking pan or line it with parchment paper for easy removal of the cookie bars later. Using parchment paper can help prevent sticking and makes cleanup a breeze.
- Cream the butter and sugars: In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until the mixture is light and fluffy. This process usually takes about 2-3 minutes. The air incorporated into the mixture will help give your cookie bars a soft texture.
- Add the eggs and vanilla: Add the eggs, one at a time, mixing well after each addition. Stir in the vanilla extract, which adds depth to the flavor of the cookie bars.
- Mix dry ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. This step ensures even distribution of the leavening agent and salt throughout the flour, leading to consistent baking results.
- Combine wet and dry ingredients: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix, as this can lead to tough cookie bars.
- Incorporate chocolate and marshmallows: Gently fold in the semi-sweet chocolate chips, mini marshmallows, and graham cracker crumbs until they are evenly distributed throughout the dough.
- Spread the cookie dough: Spread the cookie dough mixture evenly into the prepared baking pan. Use a rubber spatula to ensure an even layer.
- Add toppings: Sprinkle the additional chocolate chips and mini marshmallows on top of the cookie dough. This will give your S’mores Cookie Bars an extra layer of gooey goodness.
- Bake: Place the baking pan in the preheated oven and bake for 25-30 minutes. Keep an eye on the edges; they should be golden brown, and a toothpick inserted into the center should come out clean.
- Cool and cut: Allow the cookie bars to cool in the pan for at least 15 minutes. This cooling time helps them set, making them easier to cut into squares. Once cooled, slice them into squares and serve!
