S’mores Cookie Bars

Yield: 24 Bars (9X13-inch pan)

Prep Time: 15

Cook Time: 32

Total Time: 47

Ingredients

1 cup (227 g) salted butter, softened to room temperature
1 ½ cups (318 g) packed light brown sugar
1 teaspoon vanilla
2 large eggs
2 cups (284 g) all-purpose flour
2 cups (200 g) graham cracker crumbs
1 teaspoon baking powder
¼ teaspoon salt
7-ounce jar marshmallow creme or fluff
2 cups (340 g) milk or semisweet chocolate chips

Instructions

Preheat the oven to 350 degrees F. Line a 9X13-inch pan with foil or parchment (for easy removal of the bars after they've baked and cooled). Lightly grease the foil with cooking spray and set aside.
In a large bowl with an electric mixer on medium speed (or in the bowl of a stand mixer fitted with the paddle attachment), beat the butter and brown sugar until light and fluffy, about 2 minutes.
Beat in the eggs and vanilla until well combined.
Add the flour, graham cracker crumbs, baking powder, and salt and mix until combined.
Press half the dough into the bottom of the prepared pan. Dollop the marshmallow topping on top of the cookie base and gently spread into an even layer with a lightly greased spatula.
Sprinkle the chocolate chips on top. Scatter the remaining dough in pieces over the top.
Bake until golden brown at the edges but still soft in the middle, 30-32 minutes. Cool completely. Remove the bars from the pan using the foil or parchment overhang. Cut into squares and serve.

Notes

Marshmallow Fluff: don’t be tempted to substitute mini-marshmallows for the fluff/creme. The marshmallows completely dissolve while baking.
