Preheat oven to 350 degrees, line pans with parchment paper or silpat mats
In a medium bowl, whisk flour and baking soda and set aside.
In a separate bowl, using a mixer, beat together butter, sugars and instant pudding mix until thoroughly combined.
Add in eggs and butter extract and mix until incorporated.
Slowly add in dry ingredients until fully combined.
Gently fold in 1 cups of mini M&M’s, ½ cup M&M's and chocolate chips.
Pour the remaining cup of mini M&M's into a bowl and set aside.
Using a large cookie or ice cream scooper, scoop the dough and release dough into your hand and roll only tops of cookies in mini M&M's. The mini M&M's should be close together, they will spread out while baking. (If you don't have a scoop, roll balls in hands about 1.5" across.)
Bake 6 cookies to a cookies sheet at 350 for 12-14 minutes.
Let cookies cool on baking sheet a few minutes before moving to a wire rack.
