White Chocolate Death by Chocolate Cookies

My Brother recently just ruptured his Achilles Tendon and so I thought that I would make him some cookies and send them to him in the mail, I mean who wouldn't love these rich chocolaty cookies?
Here is the recipe taken from The All American Cookie Book.

1 Cup of unsalted butter (room temperature)
1 1/4 cups of granulated sugar
1 cup unsweetened cocoa powder, sifted.
1/2 tsp. baking soda
1/8th tsp. of salt
2 large eggs
1 Tbsp. light corn syrup
2 Tsp. real vanilla extract
2 1/2 cups all-purpose flour
1 1/2 cups white chocolate chips
1/2 semisweet chocolate chips

Preheat oven to 350 degrees F and grease 2 cookie sheets or line them with waxed paper.
In a stand mixer fit with the paddle attachment or with a hand held mixer beat the sugar and butter together until light and fluffy. Reduce the speed to low and add the cocoa powder, baking soda, and salt and mix until smooth being sure to scrape down the edges. Next, add the eggs, corn syrup, and vanilla and beat until smooth. Beat (cautiously) or stir in the flour until it's all incorporated. Then finally mix in the white and semisweet chocolate chips.

Use a tablespoon and form balls and place them on a cookie sheet (about the size of a golf ball) 2 1/2 inches apart. Flatten the balls with your fingers so they will all be the same thickness. Bake off in the oven for about 9-12 minutes or when you press on the middle the cookie is slightly firm. Transfer to a wire rack and let cool for about 5 minutes. These are best eaten within the day they are made but if wrapped properly should stay for at least 3 days.
Enjoy!
