Step-by-Step Instructions

Spreading the cookie base for S'more Cookie Bars in a baking pan. — Start your S’more Cookie Bars by creating the perfect cookie base with our simple step-by-step instructions!

Preheat and Prep: Preheat your oven to 375°F (190°C). Grease and line a 9×13 inch baking pan with parchment paper, leaving some overhang on the sides. This will make it easy to lift the finished bars out of the pan.
- Tip: Lining with parchment paper is a game-changer for easy cleanup!
Cream the Sugars and Butter: In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy. This usually takes about 2-3 minutes with an electric mixer.
- Tip: Make sure your butter is softened but not melted for the best cookie dough consistency.
Add Wet Ingredients: Beat in the eggs one at a time, then stir in the vanilla extract. Mix until everything is well combined.
Combine Dry Ingredients: In a separate medium bowl, whisk together the all-purpose flour, baking soda, and salt.

Gradually Add Dry to Wet: Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix the dough.
- Tip: Overmixing can lead to tough cookies, so stop mixing as soon as you see no more streaks of flour.
Layer the Pan: Press the graham cracker squares evenly across the bottom of the prepared baking pan to create a single layer. You might need to break some crackers to fit.
- Tip: Press the graham crackers down gently to ensure they adhere slightly to the pan.
Spread the Cookie Dough: Dollop the cookie dough evenly over the graham cracker layer. Use your fingers or the back of a spoon to gently spread the dough into an even layer. Don’t worry if it doesn’t perfectly cover the graham crackers.
Sprinkle with Chocolate Chips: Sprinkle the milk chocolate chips evenly over the cookie dough layer.

Top with Marshmallows: Scatter the mini marshmallows evenly over the chocolate chips, creating a nice, fluffy layer.
- Tip: For extra gooeyness, you can gently press some of the marshmallows down into the chocolate chips.
Bake: Bake in the preheated oven for 18-22 minutes, or until the edges of the cookie bars are golden brown and the marshmallows are puffed and lightly golden. Keep a close eye on them in the last few minutes to prevent burning.

Cool and Cut: Let the S’more Cookie Bars cool completely in the pan before cutting them into squares. This will help them hold their shape.
- Tip: Be patient! Letting them cool completely makes for much cleaner cuts.

These S’more Cookie Bars are fantastic all on their own, but if you’re looking to make them even more special, here are a few serving suggestions. A tall glass of cold milk is a classic pairing that complements the sweetness perfectly. For a more indulgent treat, try serving them warm with a scoop of creamy vanilla ice cream. On a chilly evening, a warm cup of hot cocoa would also be a wonderful accompaniment, enhancing that cozy, campfire feel. These bars are also perfect for parties and potlucks – just cut them into smaller squares for easy serving!

Want to make your S’more Cookie Bars absolutely perfect? Here are a few handy tips:

Use Quality Chocolate: For the best flavor, opt for good quality milk chocolate chips.
Don’t Overbake: Keep an eye on the bars while they’re baking. You want the edges to be golden and the marshmallows lightly toasted, but still soft and gooey.

Even Layers: Try to spread the cookie dough and marshmallows as evenly as possible for consistent flavor and texture in every bite.
For Extra Gooeyness: If you love super gooey marshmallows, you can add an extra handful on top in the last 5 minutes of baking.
Cool Completely: Resist the urge to cut into them while they’re still hot! Letting them cool completely will prevent them from falling apart.

Storing and Reheating Tips

Storing: Leftover S’more Cookie Bars can be stored at room temperature in an airtight container for up to 3-4 days. For longer storage, you can keep them in the refrigerator for up to a week.

Freezing: To freeze these S’more Cookie Bars, let them cool completely and then cut them into individual squares. Wrap each square tightly in plastic wrap, then place them in a freezer-safe bag or container. They can be frozen for up to 2-3 months.

Reheating: To enjoy a warm and gooey S’more Cookie Bar, you can microwave a square for about 10-15 seconds. Alternatively, you can reheat them in a preheated oven at a low temperature (around 300°F or 150°C) for a few minutes until warmed through.
