Step 1

Preheat the oven to 375°F. Line two baking sheets with silicone baking mats or parchment paper and set aside. In a large bowl, cream together the butter and sugars with beaters. Mix for 1-2 minutes, or until creamy and fluffy. Add the eggs and vanilla and mix just until combined.

Step 2

Add the flour, baking soda and salt and mix just until combined. Fold in the chocolate chips and M&M’s. Refrigerate dough for 15 to 30 minutes if time allows.

Step 3

Using a large cookie scoop (about 3 Tablespoons), scoop the cookie dough onto the baking sheet about 2 inches apart. Place any extra chocolate chips or M&M’s on the top of the cookies if desired.

Step 4

Bake for 7-10 minutes, or until the edges are barely golden brown. Allow cookies to set on pan for 2-3 minutes, and then remove to a cooling rack.
