S'mores Cookie Bars
Ingredients
- 3/4 cup unsalted butter, melted
- 1/2 cup sugar
- 3 tablespoons sugar
- 3/4 cup packed brown sugar
- 1 large egg
- 1 egg yolk
- 1 1/2 teaspoons vanilla extract
- 3/4 teaspoon baking soda
- 3/4 teaspoon salt
- 2 1/4 cups all-purpose flour
- 2 1/4 cups chocolate chips
- 1 1/2 cups mini marshmallows
- 8 graham cracker sheets, enough to line the bottom of your pan

Preheat oven to 350°F (175°C). Line an 8x8 or 9x9 baking pan with parchment paper, leaving an overhang on two sides to easily lift the bars out later.

In a large bowl, combine the melted butter and both the granulated sugar and packed brown sugar. Mix with a whisk or electric mixer until smooth and well combined.

Add the large egg, egg yolk, and vanilla extract to the butter and sugar mixture. Mix well until fully incorporated and the mixture is light and creamy.

In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix the dough.

Fold in 2 1/4 cups of the chocolate chips into the cookie dough until evenly distributed.
⏱️ 1 min - 6
Arrange the graham cracker sheets in a single layer on the bottom of the prepared baking pan, breaking them as needed to fit snugly and cover the entire bottom.

Press half of the cookie dough evenly over the graham cracker layer. An offset spatula or your hands can help with this. Sprinkle the mini marshmallows evenly over the dough layer. If desired, add an extra layer of chocolate chips over the marshmallows for extra chocolatey goodness.

Carefully place the remaining cookie dough on top of the marshmallow and chocolate chip layer. Gently press it down and seal the edges as best as you can. It's okay if some marshmallow peeks through. Sprinkle additional chocolate chips on top of the final cookie dough layer, if desired.

Bake for 22–28 minutes, or until the edges are set and lightly golden brown, and the center is still slightly soft. The bars will continue to set as they cool.

Allow the S'mores Cookie Bars to cool completely in the pan on a wire rack before slicing into bars. This can take at least 1 hour to ensure they are firm enough to cut cleanly.
