Ingredients

1.5 cups graham cracker crumbs (about 10 full sheets)
0.5 cup unsalted butter (melted)
1 cup all-purpose flour
1 tsp baking powder
0.5 tsp salt
0.75 cup brown sugar
0.5 cup granulated sugar
2 large eggs
1 tsp vanilla extract
1.5 cups mini chocolate chips
1.5 cups mini marshmallows

Directions

Preparation Steps

Preheat the Oven: Preheat your oven to 350°F (175°C). This prepares the oven for even baking.
Prepare the Baking Dish: Grease a 9×13 inch baking dish with a bit of butter or cooking spray to prevent sticking.
Mix the Dry Ingredients: In a large bowl, combine the graham cracker crumbs, flour, baking powder, and salt.
Combine Butter and Sugars: In another bowl, mix the melted butter with brown sugar and granulated sugar until well combined.
Add Eggs and Vanilla: Beat in the eggs, one at a time, and mix in the vanilla extract until smooth.
Combine Mixtures: Gradually add the dry ingredient mixture to the wet mixture. Stir until everything is well incorporated.
Fold in Chocolate Chips: Gently fold in the mini chocolate chips and mini marshmallows, making sure they are evenly distributed throughout the batter.
Transfer to Baking Dish: Pour the mixture into your greased baking dish and spread it out evenly.
Bake: Bake in the preheated oven for 20-25 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out mostly clean (it’s okay if a few chocolate chips stick to the toothpick).
Cool and Cut: Once baked, remove from the oven and allow it to cool in the pan for about 10-15 minutes. Cut into squares and enjoy warm or let them cool completely.

Tips and Variations

Helpful Tips

Chilling the Dough: If you find the dough too sticky, you can chill it in the refrigerator for about 30 minutes before spreading it into the baking dish.
Ingredient Swaps: You can replace half the all-purpose flour with whole wheat flour for a slightly healthier option. Also, try different types of chocolate chips, like white chocolate or peanut butter chips, for a unique flavor.
Avoiding Soggy Bars: Make sure to let them cool properly before cutting to avoid sogginess.
Dietary Adaptations: For gluten-free options, use gluten-free graham crackers and flour. If vegan, you can substitute eggs with flax eggs or applesauce.

Common Mistakes

Overmixing the Batter: Mix just until combined; overmixing can lead to tough bars.
Baking Too Long: Keep an eye on the bars while baking. Overbaking can dry them out, leading to a less enjoyable texture.

Storage and Serving Suggestions

To store your leftover s’mores cookie bars, place them in an airtight container at room temperature. They will stay fresh for up to 3 days. If you want to extend their life, you can refrigerate them for up to a week.

To reheat, simply pop a square in the microwave for about 10-15 seconds, just enough to warm up the chocolate and marshmallows. They can also be enjoyed cold; many people prefer the texture and flavor when they are less gooey.

For serving, consider pairing these bars with a scoop of vanilla ice cream, drizzling chocolate or caramel sauce on top, or adding fresh fruit like strawberries for a twist. They are perfect as a stand-alone dessert or as part of a dessert platter.

FAQs

Can I use regular-sized chocolate chips instead of mini?

Yes, you can use regular-sized chocolate chips; just ensure they are evenly distributed in the batter.

Do I need to use eggs in this recipe?

While eggs help with binding and texture, you can substitute them with flax eggs or applesauce for a vegan option.

Can I freeze s’mores cookie bars?

Yes! To freeze, wrap the bars tightly in plastic wrap or aluminum foil and place them in a freezer bag. They can be frozen for up to three months. Thaw overnight in the refrigerator before enjoying.

What can I use instead of graham cracker crumbs?

You can use crushed digestive biscuits or vanilla wafer cookies as a substitute for graham cracker crumbs.

How can I make these bars more chocolatey?

Feel free to increase the amount of chocolate chips or add a layer of chocolate ganache on top after baking for extra chocolate flavor.
