Take the ice cream out of the freezer to soften.
1 quart vanilla ice cream
In a saucepan, melt the unsalted butter until it turns brown and develops a nutty aroma. Remove from heat and let it cool until it solidifies at room temperature. Once the butter solidifies, transfer it to a large bowl along with the sugars and salt. Whisk until well combined.
1 cup unsalted butter, ¾ cup white granulated sugar, 1 ½ cups brown sugar, 2 teaspoons salt
Add the eggs and vanilla extract to the mixture, whisking until smooth.
2 eggs, 2 teaspoon vanilla extract
Sift in the flour and baking soda, folding until just combined.
2 cups all purpose flour, 1 teaspoon baking soda
Fold in the mini chocolate chips to the cookie dough.
1 cup semi sweet mini chocolate chips
Set aside a portion of the cookie dough for later use with the ice cream. Refrigerate the remaining dough, covered with plastic wrap or in a tightly sealed container, for at least 30 minutes before baking.
While the cookie dough chills, spread the softened ice cream evenly in a baking dish lined with parchment paper to create a layer about 1 ½ -2 inches thick. Scatter small dough balls from the reserved cookie dough throughout the ice cream layer, mixing and folding if necessary to distribute evenly. Place the dish in the freezer for 1 hour.

Preheat the oven to 325 degrees Fahrenheit. Use a 1-inch cookie scoop to form dough balls and place them on a baking sheet lined with parchment paper. Bake for 11 to 13 minutes or until the edges turn golden brown.
Immediately after removing from the oven, shape each warm cookie using a 3-inch cookie cutter placed around it, sliding the cutter to mold the cookie into shape. This ensures uniform cookies that match the size of the ice cream circles to be cut later.
Allow the cookies to cool completely. Meanwhile, use the same cookie cutter to cut out circles of ice cream from the frozen layer. Sandwich each ice cream circle between two cookies.
Repeat the process for all ice cream and cookies, then return the assembled ice cream sandwiches to the freezer for another 30 minutes before serving.
