Description

S’mores Cookie Bars are a delightful layered treat combining a graham cracker crust, gooey cookie dough studded with mini marshmallows and chocolate chips, and topped with melted Hershey’s chocolate bars. These bars capture the classic s’mores flavor in an easy-to-bake dessert perfect for gatherings or sweet cravings.


Ingredients

78 (78-109 g) graham crackers (full sheets/unbroken rectangles)

1 cup (226 g) unsalted butter, room temperature (2 sticks)

¾ cup (150 g) granulated sugar

¾ cup (150 g) light brown sugar, gently packed

2 large eggs

2 tsp vanilla extract

3 cups (360 g) all-purpose flour (stirred, spooned, and leveled)

¾ tsp salt

¾ tsp baking soda

½ cup (135 g) semi-sweet chocolate chips

1 cup (45 g) mini marshmallows

2 regular sized Hershey’s Milk Chocolate Bars (two 1.55 oz / 43 g bars), broken into squares


Instructions

  1. Preheat oven to 375°F. Line a 13×9-inch pan with parchment paper, leaving a 2-inch overhang on the sides.
  2. Place graham crackers in a single layer covering the full pan, breaking them into sections as needed to fit properly.
  3. In the bowl of an electric mixer fitted with the paddle attachment, cream together the butter, granulated sugar, and light brown sugar until light and fluffy. Add eggs and vanilla extract, mixing well and scraping down the bowl as needed.
  4. In a separate bowl, whisk together the flour, salt, and baking soda. Add this dry mixture to the butter mixture along with the chocolate chips and mini marshmallows. Mix until just combined.
  5. Evenly spread and press the cookie dough over the graham cracker layer in the pan. Add additional mini marshmallows on top if desired.
  6. Bake at 375°F for 25–30 minutes, or until golden brown and a toothpick inserted in the center comes out clean. If the edges brown faster than the center cooks, cover loosely with foil.
  7. Remove from the oven and immediately place the broken Hershey’s chocolate pieces on top while the bars are still warm. Allow to cool for 20–30 minutes before lifting the bars out of the pan using the parchment paper overhang. Cut into squares and serve.

Notes

Use milk chocolate or dark chocolate bars instead of Hershey’s for different chocolate flavors.

Add chopped nuts such as pecans or walnuts for crunch.

Mix in peanut butter chips or white chocolate chips for variety.

Swap mini marshmallows for regular-sized marshmallows cut into smaller pieces.

Use gluten-free flour blend to make it gluten-free.

Store at room temperature in an airtight container or covered in the pan with plastic wrap to keep bars soft and gooey.

Refrigerate if you prefer the chocolate topping to firm up, but bars may become less gooey.

Freeze cooled bars in an airtight container for up to 2 months; thaw before serving.

Baking at 350°F for 35 minutes is an option for more even baking.

A metal or aluminum pan bakes bars more evenly than glass pans.
