extraextraM&M's and mini chips for topping each cookie dough blob(optional)
Instructions
Preheat the oven to 375°F.
In a medium bowl, whisk together the flour, cornstarch, baking soda and salt. In a separate large bowl, use an electric mixer to combine the butter and sugars. Mix in the vanilla and eggs too. Add the flour mixture and mix until combined. Stir in the chocolate chips and M&M's.
Drop by rounded heaping teaspoonfuls onto parchment or silpat lined baking sheets. Top each cookie dough blob with a few more M&M's and chips, if you want them to look pretty when they're baked. Bake 9 to 11 minutes, or until golden brown. Cool on baking sheets for a few minutes before transferring them to a cooling rack to cool completely.
