M&M's^® Cookies:  Preheat oven to 350 degrees F (177 degrees C). Place one oven rack in the top third of the oven, and one oven rack in the bottom third of the oven. Line two baking sheets with parchment paper. 

In a large bowl, whisk together the flour, baking soda, and salt.

In the bowl of your electric mixer (or with a hand mixer), beat the butter and sugars until light and fluffy (about 2 - 3 minutes). Scrape down the sides of the bowl. Add the egg and egg yolk, beating until well combined. Beat in the vanilla extract.

Gradually add the flour mixture to the creamed mixture and beat just until incorporated. Scrape down the sides of the bowl as needed. (If the batter is very soft, cover and refrigerate for 30 to 60 minutes or until firm.)

Using a 1/4 cup (60 ml), an ice cream scoop, or two spoons, form batter into large balls. Place six balls of dough on each baking sheet. Gently flatten each ball of dough into a 2 1/2 inch (6.5 cm) round. Completely cover the tops of the cookies with the M&M's^® or Smarties^®. Gently press the candies into the dough. Bake the cookies for about 14 - 17 minutes, rotating the baking sheets halfway through the baking time. The cookies are done when they are light golden brown in color and just set around the edges. They will still seem a little soft in the center but they will firm up as they cool. Remove from oven and let the cookies cool a few minutes on the baking sheet before transferring them to a wire rack to cool.

Makes about 15 large cookies.
