Levain Cookie Copycats

Again, I made the Levain cookie recipe, but this time I used walnuts and chocolate chips in addition to chocolate chunks.  I'm obsessed with massive cookies and I want to try the real version of these cookies,

Levain Chocolate Chip Cookie Clone

from vanilla sugar
2 sticks unsalted butter, cold
3/4 cup granulated sugar
3/4 cup packed brown sugar
2 large eggs
1 teaspoon vanilla
3 cups all purpose flour
3/4 teaspoon salt (I used sea salt)
1 teaspoon baking powder
1/2 teaspoon baking soda
12 ounces (2 cups) good quality semisweet chocolate chips or chopped chocolate (In addition, I used 2 squares of chopped Baker's chocolate)
1 cup nuts (pecans or walnuts) (I used walnuts)

If using dough right away, preheat oven to 375 degrees F.

In a mixing bowl, using an electric mixer, beat butter and both sugars just until creamy. Don’t overbeat. Add the egg and vanilla and beat just until incorporated.

Stir together flour, baking soda, baking powder and salt. When thoroughly mixed, add to batter and stir just until blended. Stir in chocolate chips.

Divide dough into 12 big 4 oz lumps. Bake on ungreased cookies sheets (one sheet at a time).

Bake times:

Put the cookies in a 375 degree oven and set timer for 8 minutes. When timer rings, without opening oven or removing cookies, reduce heat to 325 degrees and bake for another 8-10 minutes or until cookies appear set.
