No scooping or rolling, these cookie bars are loaded with chocolate chips and colorful Easter M&M'S and perfect for a crowd.
Preheat oven to 350 degrees. Line a 9x13 cake pan with foil, leave some overhang to make removal easier. Spray foil generously with nonstick cooking spray.
In the bowl of a stand mixer, beat butter, granulated sugar, and brown sugar together until fluffy. Add in eggs and vanilla extract and continue to beat. Lower speed of mixer and add flour, baking soda and salt, and mix until combined. Add M&M's, mini chocolate chips and white chocolate chips and give a final stir, reserving some M&M's, mini chocolate chips and white chocolate chips for topping cookie bars.
Transfer cookie dough to prepared baking dish. Press additional M&M'S, mini chocolate chips and white chocolate chips into top of cookie dough. Bake 30 to 35 minutes until cookie bars are just set, but not overly browned. Do not over bake, cookie bars should be soft in the center. Let cool completely and cut.
