Kitchen Tools You’ll Need

• Mixing bowls
• Baking pan
• Electric mixer or whisk
• Rubber spatula
• Measuring cups and spoons

Ingredients

• 1 cup butter, room temperature (provides moisture and richness)
• 1/2 cup granulated sugar (adds sweetness and texture)
• 1 cup light brown sugar (introduces deeper flavor and moisture)
• 2 large eggs, room temperature (binds ingredients and provides structure)
• 2 teaspoons pure vanilla extract (enhances overall flavor)
• 3 cups flour (gives structure and bulk)
• 1 teaspoon baking soda (helps the bars rise and become light)
• 1 teaspoon salt (balances sweetness)
• 4 whole graham crackers, broken into smaller pieces (adds crunch and flavor)
• 2 1/2 cup mini marshmallows (adds sweetness and a chewy texture)
• 1 cup semi-sweet chocolate chips (provides rich, chocolate flavor)
• 2 Hershey’s milk chocolate bars, broken into mini bars (adds classic chocolate taste)

How to Make Smores Cookie Bars

Step 1. Begin by preheating your oven to the desired temperature to prepare for baking. Grease and line a baking pan with parchment paper, allowing some overhang for easy removal later. This will help the cookie bars maintain a nice shape and prevent sticking.

Step 2. In a large bowl, cream together the room temperature butter, granulated sugar, and light brown sugar using an electric mixer or a whisk. Mix until the mixture is light and fluffy, taking care to ensure that there are no lumps of brown sugar left. This step helps incorporate air for better texture in the finished bars.

Step 3. Next, add the eggs, one at a time, to the butter-sugar mixture, mixing well after each addition. Stir in the pure vanilla extract until everything is combined smoothly. This adds moisture and richness to the cookie bars, creating a soft base.

Step 4. In a separate bowl, whisk together the flour, baking soda, and salt. Gradually mix this dry ingredient mixture into the butter mixture, stirring until just combined. Be careful not to overmix, as this can affect the texture of the bars.

Step 5. Once the dough comes together, gently fold in the broken graham crackers, mini marshmallows, and chocolate chips using a rubber spatula. This helps distribute the chocolate and marshmallows evenly within the dough. The dough should have a thick and slightly sticky consistency, packed with tasty morsels.

Step 6. Spread the mixture evenly into your prepared baking pan, smoothing the top with the spatula. Aim for an even layer to ensure uniform baking. Press down lightly to compact the dough, which will help the bars hold their shape after baking.

Step 7. Bake the bars in the preheated oven until they are golden brown and the edges appear set. The center might seem a little soft, but it will firm up as it cools. Watching the edges become firm is a great cue that they are done.

Step 8. Once baked, remove the pan from the oven and let it cool completely on a wire rack. This cooling process allows the marshmallows to set slightly, making cutting the bars easier. Keep an eye on the visual doneness, as the marshmallows should not be overly browned.

Step 9. After the bars have cooled, use the parchment overhang to lift them out of the pan. Cut them into squares or rectangles as desired. The chocolate can be slightly melty, enhancing the overall appeal of each bar.

Step 10. Serve the S’mores Cookie Bars as a delightful treat for family and friends. Whether for dessert, a snack, or a cozy evening in, these bars are sure to please.

Serving Suggestions

These S’mores Cookie Bars are lovely for breakfast with a cup of coffee or enjoyed as a sweet afternoon snack. They are also perfect for family meals, whether served warm with a scoop of ice cream or as part of a dessert platter at gatherings. These bars hold up well, so leftovers can be wrapped and saved for later enjoyment, making for an easy and satisfying treat throughout the week.

Pro Tips for Best Results

• Ensure your butter is at room temperature for proper creaming with sugars, which will enhance the texture.
• Don’t skip the cooling step; this allows the marshmallows to firm up, making it easier to cut the bars.
• Press down the dough lightly in the pan to help the bars hold their shape after baking.
• Rotate the pan halfway through baking for even cooking, particularly if your oven has hot spots.
• Use a sharp knife for cutting the bars once they’ve cooled to achieve neat edges.
• For a richer flavor, consider using dark chocolate chips instead of semi-sweet.

Common Mistakes to Avoid

1. Using cold butter: Cold butter can lead to dense bars, as it won’t cream well with the sugars. Always use room-temperature butter for the right texture.
2. Overmixing the dough: Mixing the dough too much can result in tough bars. Stop mixing once the dry ingredients are just incorporated for a light texture.
3. Not cooling enough: Trying to cut the bars before they’ve cooled completely can cause them to fall apart. Patience is key for clean cuts.
4. Skipping the parchment paper: Without parchment, the bars may stick to the pan, making removal messy. Always line your pan for easy lifting.
5. Underbaking the bars: Bars that are taken out too early may be overly soft and crumbly. The edges should be golden brown with a set center when done.
6. Ignoring ingredient temperature: Ingredients like eggs and butter should be at similar temperatures to blend seamlessly. Cold eggs can cause curdling, affecting the final texture.

Variations & Substitutions

• For added texture, consider mixing in nuts like walnuts or pecans.
• Swap out mini marshmallows for larger, cut-up marshmallows if preferred.
• You can easily change the type of chocolate using milk or dark chocolate as per your taste preference.

Storage & Reheating

Store the cookie bars in an airtight container at room temperature for up to three days. If you wish to extend their life, refrigerate them, where they will last up to a week. For longer storage, they can be frozen in individual squares, wrapped tightly in plastic wrap, for up to three months. To reheat, simply warm in the oven or microwave until just heated through, to preserve their chewy texture.
