Introduction
S’mores cookie bars combine the nostalgic flavors of classic s’mores into a delicious, easy-to-make dessert. With a buttery cookie base, melted chocolate, and gooey marshmallow topping, these bars are perfect for satisfying your sweet tooth any time of year.

Ingredients
- 1/2 cup softened butter
- 1/3 cup brown sugar
- 1/4 cup granulated sugar
- 1 egg
- 1 tsp vanilla extract
- 1 & 1/2 cups all-purpose flour
- 1/2 cup finely crushed graham crackers (about 3.5 sheets)
- 5 standard Hershey bars
- 1 & 1/2 cups marshmallow fluff
- 1/4 tsp salt
- 1/2 tsp baking soda
Instructions
- Step 1: Preheat your oven to 350°F (175°C) and line an 8×8 inch baking pan with parchment paper.
- Step 2: In a mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until fluffy. Beat in the egg and vanilla extract until well combined.
- Step 3: Gradually add the flour, crushed graham crackers, salt, and baking soda; mix until just combined to form the dough.
- Step 4: Press half of the dough evenly into the prepared baking pan. Place the pan in the freezer for about 15 minutes to firm up the dough layer.
- Step 5: Break the Hershey bars into pieces and layer them evenly over the chilled dough. Spread the marshmallow fluff evenly on top of the chocolate layer.
- Step 6: Carefully flip the remaining dough over the marshmallow layer to cover it. Bake in the preheated oven for approximately 25 minutes or until the top is golden brown.
- Step 7: Allow the bars to cool completely in the pan before slicing into squares and serving.
Tips & Variations
- For a nuttier flavor, add 1/2 cup chopped toasted nuts like pecans or walnuts to the dough.
- Try using dark or milk chocolate bars instead of Hershey bars for a different chocolate taste.
- To make cutting easier, refrigerate the bars after baking and cooling to help them set firmly.
- If you don’t have marshmallow fluff, mini marshmallows can be melted on top during the last 5 minutes of baking.
Storage
Store the s’mores cookie bars in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week or freeze airtight for up to 2 months. Reheat in a microwave for 10-15 seconds to soften before serving, if desired.

FAQs
Can I use a different size baking pan?
Yes, but baking times will vary. Using a larger pan will result in thinner bars and a shorter bake time, while a smaller pan will produce thicker bars that may need additional baking.
Can I prepare these bars ahead of time?
Absolutely! You can assemble the bars and freeze them before baking. When ready, bake directly from frozen, adding a few extra minutes to the baking time.
