1 teaspoon salt
1 cup (2 sticks) butter, at room temp
3/4 cup sugar
3/4 cup light brown sugar
1 teaspoon pure vanilla extract
2 large eggs
1-12ounce bag chocolate chips (2 cups)

3 sticks softened butter
1 1/2 cups light brown sugar, packed
4 large eggs
2 2/3 cups all purpose flour
1 tsp. baking powder
1 tsp. baking soda
1/4 tsp. salt
1 cup milk
2 tsp. vanilla extract

3 sticks softened butter
3/4 cup light brown sugar, packed
3 1/2 cups powdered sugar
1/2 tsp. salt
2 tbsp. milk
1 tsp. vanilla extract

To make the cookie dough:
In a medium bowl, whisk the flour, baking soda, and salt. Set aside.
In the bowl of a stand mixer, at medium-low speed, mix the butter with the sugar and brown sugar. Raise the speed to medium-high and mix until creamy, light, and fluffy. Scrape down the bowl. Add the vanilla and eggs. Mix together until incorporated.
Add half of the four mixture. Mix until just combined, scrape down the bowl. Add the remaining flour mixture and mix until just combined. Stir in the chocolate chips.
Using a small ice cream/melon baller, scoop, shape the dough into balls. Freeze on a baking sheet lined with a silicon mat or parchment paper. 
Use the leftover cookie dough to make mini cookie toppers for the cupcakes. Spread all the leftover dough on a cookie sheet lined with parchment or a silicone baking mat. Try to spread it fairly evenly. Bake until the cookie is lightly browned, do not over cook. Let cool about a minute. While the cookie is still warm cut out mini cookies using a the end of a large piping tip or a mini round cutter. Do this before the cookie cools down too much or you may not be able to cut the mini cookies out.
