1largeegg
1largeegg white
1 ½teaspoonspure vanilla extract
1 ½cupsquick-cooking rolled oats
1cupsemisweet chocolate chips
½cupwhite chocolate chips
¾cupsweetened shredded coconut
Instructions
In a medium bowl, whisk the flour with the baking soda, baking powder and salt.
In a large bowl, using an electric mixer, beat the butter with the brown sugar at medium speed until blended. Beat in the granulated sugar until light and fluffy, about 2 minutes. Beat in the whole egg, egg white and vanilla.
At low speed, beat in the dry ingredients, in 2 additions. With a large wooden spoon, mix in the oats, semisweet and white-chocolate chips and the coconut. Cover the cookie dough and refrigerate for 1 hour, until chilled. Alternatively, you can scoop the cookie dough onto dinner plates, cover and chill the pre-formed dough balls.
Preheat the oven to 375°. Line baking sheets with parchment paper. Using a rounded tablespoon, spoon mounds of dough onto the baking sheets, at least 3 inches apart. Bake the cookies for about 14 minutes, until golden and just set. Let the cookies cool on the baking sheets for 5 minutes, then transfer them to a rack to cool completely.
