Ingredients

1 stick butter, softened

3/4 c. sugar

1 tsp. pure vanilla extract

1 c. all-purpose flour

1 tsp. kosher salt

1 c. mini chocolate chips

20 jumbo marshmallows

2 large Hershey’s chocolate bars, split into two

Preparation

Step 1Make cookie dough: In a stand mixer, beat butter, sugar, and vanilla until smooth. Add flour and salt and beat until combined. Stir in chocolate chips. Step 2Line an 8"-x-8" baking dish with parchment paper so there’s an overhang. Transfer half the cookie dough to the parchment paper and pat down so it creates a thin even layer. Cover with another piece of parchment, leaving an overhang, and repeat with remaining cookie dough. Transfer to the freezer until firm, 2 hours.Step 3Remove pan from freezer and separate layers of cookie dough. Cut into eight large squares. Step 4Over a flame on the stove or under the broiler in an oven, toast marshmallows. Step 5Sandwich chocolate and marshmallows in between two squares of cookie dough.
