Preheat the oven to 350℉ and line a cookie sheet with parchment paper or a silicone mat.
Beat the butter, granulated sugar, and brown sugar together on high speed until light and creamy, at least 3 minutes.
Cream in the pudding mix, and then stir in the eggs and vanilla. Beat on high for 2-3 minutes more.
In a separate bowl, whisk together flour, and baking soda. Gradually add to the wet mixture until just combined.
Fold 1 1/2 cups of chocolate chips into the batter with a spatula, until fully combined.
Scoop out about 3 tablespoons of dough per cookie and place on the cookie sheet, about 2 inches apart. Press down the remaining chocolate chips on top of the cookies.
Bake for about 10 minutes. Let cool on the cookie sheet for at least 5 minutes before moving to a wire rack to set and cool.
Notes
You don't need to chill the dough for these cookies because they don't spread too much.
