Preheat oven to 350℉.
In the bowl of a stand mixer, cream butter and both sugars together until light and fluffy.
Add eggs and vanilla and combine.
Add flour, baking soda and salt and mix until just combined.
Using a spatula, fold in chocolate chips and M&Ms.
For best results, refrigerate dough for 30 min!!
Scoop out 2Tbs size balls of dough onto a cookie sheet.
Bake for 8-10 min (9 min was my sweet spot but just watch them. As soon as the edges are golden brown, they are done!)
Let cool on the pan for about 2 min before transferring to a cooling rack to cool the rest of the way.
ENJOY!!
