Ingredients

1 cup unsalted butter very soft, almost melted
1 cup granulated sugar
1 ½ cups brown sugar packed
2 Tbsp. milk whole is best
3 large eggs room temperature
1 Tbsp. pure vanilla extract
3 ½ cups all purpose flour
2 teaspoon cornstarch
1 teaspoon baking soda
1 teaspoon baking powder
1 teaspoon salt
1 cups semi sweet chocolate chips (I use semi sweet but use your favorite
½ cup Valentine M&Ms
¼ cup mini semi sweet chocolate chips to sprinkle on top after baking - I use Minis but not necessary
¼ cup Valentine M&Ms to sprinkle on top after baking

Instructions

Preheat the oven to 325°F. Spray a standard half sheet pan with nonstick spray (size is 13x18) and set aside.
Add the butter and sugars together in a mixing bowl and mix on medium speed until smooth. Add the milk, eggs and vanilla. And mix until combined.
Add the dry ingredients. Mix until mostly combined.
Add the chocolate chips in and fold just until combined.
Add the batter to the prepared baking sheet. Spread evenly until smooth. All of the batter will fit perfectly, it just takes smoothing. I like to use a cake spreader.
I also like to spray my finger with cooking spray and press that way. Add the ½ cup M&Ms on top and smooth in with a spreader or butter knife.
Bake for 27-37 minutes. I start checking at 27 minutes. You will want to lightly underbake because these cook in the pan a tiny bit after removing from oven. The cookie pan should be golden, but not brown. They will be a little puffy at first but will settle. Tapping them gently on the counter will help them to settle.
Sprinkle the remaining chips and M&Ms on top. Cool completely and cut.
