Preheat oven to 375°F. Grease a large cookie sheet or line with parchment paper.
In a medium sized mixing bowl beat together the butter, brown sugar, sugar, and vanilla extract with an electric mixer until light and fluffy, about 5 minutes.
1/2 cup unsalted butter, 1/3 cup dark brown sugar, 1/3 cup granulated sugar, 1 teaspoon vanilla extract
Mix in the egg.
1 egg
In a separate bowl, combine the flour, baking soda and salt. Gradually add the flour mixture into the butter mixture until well combined.
1 cup all purpose flour, 2 tablespoons all purpose flour, 1/2 teaspoon baking soda, 1/2 teaspoon kosher salt
Stir in the chocolate chips.
1 cup semi sweet chocolate chips
Drop rounded tablespoons of the cookie dough onto the prepared cookie sheet about 2 inches apart.
Bake the cookies in the oven for 8 to 10 minutes, or until cooked through and light golden brown.
Transfer the baked cookies to a wire rack to cool completely.
Place the cooled cookies into a ziplock bag and into the freezer for 15 minutes before adding the ice cream filling.
When ready, place a scoop of ice cream onto the center of a cookie, and place another cookie on top to gently flatten down the scoop of ice cream. You can use a small frosting knife to smooth the edges.
48 ounces vanilla ice cream
If using mini chocolate chips, roll the prepared cookie ice cream sandwich sides into the mini chocolate chips. Serve immediately or return to the freezer until ready to serve.
