Line a baking sheet with parchment paper and preheat the oven to 350 degrees.
Combine the melted butter, granulated sugar, brown sugar, and eggs together with an electric mixer.
In a separate bowl, mix together the flour, salt, and baking soda.
Add the dry flour mixture to the butter mixture. Mix until combined. Add in the vanilla extract and chocolate chips.
Scoop the cookie into teaspoon size balls and place them on the baking sheet.
Chill in the fridge for 15 minutes before baking.
Bake in the oven for 20 minutes. Take the cookies out every 5 minutes and pound the baking sheet on the counter to flatten the cookies.
After 20 minutes, remove the cookies from the oven and cool. They should be golden brown.
Once the cookies have cooled, top the bottom of one cookie with a scoop of vanilla ice cream. Top with the bottom of another cookie to make a sandwich. Repeat until all cookies are used.
Store in the freezer in an airtight container.
