Complex Chewy Gooey Good Chocolate Chip Cookies

• 1 cup butter
• 1 1/2 cups whole wheat flour
• 1 cup all-purpose flour
• 1 1/2 teaspoons cornstarch
• 1 1/4 teaspoons baking soda
• 3/4 teaspoon salt
• 1/2 cup firmly packed dark brown sugar
• 1/2 cup firmly packed light brown sugar
• 1/4 cup granulated sugar
• 1 - 1 1/4 tablespoon vanilla extract
• 1 large egg
• 1 large egg yolk
• 2 cups chocolate chips
• 2 tablespoons milk (optional)

1. Preheat oven to 375u0b0.
2. Whisk together cornstarch, flours, soda and salt.
3. Melt the butter completely, but do not burn it, in the microwave or in a saucepan.
4. Cream the butter extremely thoroughly with all three sugars. Cream until you can cream no more.
5. Add egg and egg yolk, beat for an excessive time again.
6. Add vanilla (yes, that really is a tablespoon) and milk, if using. Again, cream together thoroughly.
7. Add flour mixture slowly, stirring together. Add more all-purpose flour if the dough is liquidy, but it shouldn't be as firm as a traditional cookie dough.
8. Stir in chocolate chips.
9. Chill for 2-4 hours or until quite firm.
10. Drop by scant 1/4 cups or by a cookie dropper onto greased baking sheets, bake in your 375u0b0 oven for about 13-16 minutes, until done puffing and pale golden brown.
11. Do yourself a favor and eat one warm.
