Step 1: Preheat your oven to 350°F (175°C).
Step 2: In a large mixing bowl, whisk together the melted unsalted butter with the granulated sugar and brown sugar until smooth.
Step 3: Add the ice cream, egg, and vanilla to the sugar mixture and mix until well combined.
Step 4: In another bowl, whisk together the baking soda, salt, and flour. Gradually add this to the wet mixture, stirring until just incorporated.
Step 5: Fold in the chocolate chips until evenly distributed.
Step 6: Scoop the dough onto a baking sheet lined with parchment paper, leaving space between each cookie.
Step 7: Bake for 10-12 minutes until edges are golden and centers look slightly underbaked.
Step 8: Let cool for 5 minutes on the baking sheet before transferring to a cooling rack.
