The most popular cookies I have ever made

Hi all- I should preface this by saying that I bake almost daily for all the fellow UNC music students. They tend to like me more now. I make a ton of cookies and experiment some, (one day I will post my recent maple syrup and sausage muffins). This is, though, the most popular cookie I have ever made, and it is incredibly easy:
White Chocolate dream cookies:
2 1/4 cups, (300 grams) flour
1/2 tsp baking powder
1/2 tsp salt
1/2 tsp baking soda
2 sticks butter
1 cup white sugar
1/2 cup brown sugar
1 egg
1 tsp vanilla
1 bag white chocolate chips
zest of one orange, (this is crucial! the secret ingredient you might say)
2-3 oz white and unsweetened/bittersweet chocolate

Preheat to 375
Beat egg with vanilla and set aside. Pulse flour, baking powder and soda, and salt in a food processor for 5 seconds
Cream butter in bowl of stand mixer for a few minutes or until larger in volume and lighter in color
Add sugar and increase speed. Beat for a few more minutes until light and bigger in volume
Add egg mixture, and increase speed if necessary to incorporate
Reduce speed to low and add flour mixture in three installments. Add orange zest at this time.
Add white chocolate chips.
Drop on preferably parchment covered baking sheets and bake until slightly golden, (these will not get very browned even though they will be done), or 8 or so minutes. You don't want them to get too dark because they generally become a crunchier cookie anyway, you don't want them to be crumbly.
Remove cookies. Let sit for a minute or two then transfer to racks. If you used parchment paper, make sure to put the paper underneath the racks, (you'll see why in a second)
Melt the white and dark chocolates separately in the microwave or over hot water if you really want.
Using a spoon/fork, dip in one of the chocolates and kind of fling chocolate over the cookie. You can try to drizzle beautifully if you want, but if you just aim for a Pollock-like finished product I promise people will still think you spent hours on it. After applying one chocolate this way, apply the other chocolate in the same way and let cookies sit until chocolate is set. Keep in an airtight container. (These freeze REALLY well. if you want to freeze them put them in the freezer on a cookie sheet until hard and chocolate is totally set. Then put in ziploc bags)
