Rainbow Cookies

1) Preheat the oven to 350 degrees F and prepare some sheet pans with silpats or parchment paper.
2) In a bowl, mix together the butter and sugars until well combined.
3) Add the eggs and vanilla and beat until creamy and fluffy.
4) In a separate bowl, combine the flour and baking soda.
5) Add the dry ingredients to the cookie dough and mix well.
6) Stir in the M&M’s.
7) Scoop the cookie dough onto the sheet pans (ideally with an ice cream scoop). Then comes the weird part: stack a second scoop of dough on top of each of the first scoops (so you will have two balls of dough sitting on top of each other).
8 ) Make sure to leave plenty of room between them (I baked 8 at a time on a sheet).
9) Bake the cookies about 10-12 minutes. They should be soft and pale in color – these do not turn golden brown.
10) Let the cookies cool before transferring them to a cooling rack.
11) Enjoy!
