Ingredients
Scale
Wet Ingredients
- 1/2 cup butter, softened
- 1/3 cup brown sugar
- 1/4 cup granulated sugar
- 1 egg
- 1 tsp vanilla extract
Dry Ingredients
- 1 1/2 cups all-purpose flour
- 1/2 cup graham crackers, finely crushed
- 1/4 tsp salt
- 3/4 tsp baking soda
Mix-Ins
- 5 standard Hershey bars, chopped
- 1 1/2 cups marshmallow fluff
Instructions
- Preheat Oven: Set your oven to 350°F (175°C) to ensure it reaches the proper temperature for baking the cookie bars.
- Prepare Pan: Line a 9×13 inch baking pan with parchment paper to prevent sticking and make clean-up easier.
- Cream Butter and Sugars: In a bowl, beat the softened butter together with the brown sugar and granulated sugar until the mixture is light and fluffy, which will help create a tender texture.
- Add Egg and Vanilla: Mix in the egg and vanilla extract thoroughly to combine the wet ingredients and give the dough richness and flavor.
- Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, finely crushed graham crackers, salt, and baking soda to evenly distribute the leavening agents and seasoning.
- Mix Dry into Wet: Gradually add the dry ingredients to the wet mixture, stirring gently until just combined to avoid overmixing which can make bars tough.
- Incorporate Chocolate and Marshmallow: Fold in the chopped Hershey bars and marshmallow fluff carefully to disperse pockets of melty chocolate and gooey marshmallow throughout the dough.
- Spread Dough and Bake: Evenly spread the dough into the prepared pan and bake in the oven for 20 to 25 minutes or until the edges turn golden brown and a toothpick inserted near the center comes out with a few moist crumbs.
- Cool and Slice: Allow the bars to cool in the pan for about 10 minutes, then lift them out using the parchment paper. Let cool completely on a wire rack before slicing into bars for clean cuts.
Notes
- Ensure butter is properly softened to help with even creaming of sugars and smooth dough consistency.
- Do not overbake to keep the bars soft and chewy; check the bars starting at 20 minutes.
- Using parchment paper makes removing and slicing the bars much easier.
- For a different flavor twist, try using dark chocolate chunks or white chocolate instead of Hershey bars.
- Store bars in an airtight container at room temperature for up to 3 days or freeze for longer storage.
