Recipe adapted from George Geary via wigs at eat.at
2 1/2 sticks butter, at room temperature
2 cups sugar
2 teaspoons vanilla
3 cups flour
3/4 cup Dutch process cocoa powder
1 teaspoon baking soda
1/4 teaspoon salt
2 cups white chocolate chips
1 cup semi-sweet chocolate chips
1 cup milk chocolate chips
Preheat oven to 350º. Line cookie sheets with parchment paper.
In large bowl, beat butter and sugar till light and fluffy. Add eggs and mix till incorporated, then mix in vanilla.
Sift in flour, cocoa powder, soda and salt. Mix just till blended. Add the chips and stir in by hand.
Drop by rounded tablespoons or use 1 3/4-2 inch diameter cookie scoop to dish out dough onto prepared baking sheet. Pat rounds down lightly before baking. Bake 8-10 minutes. The cookies will not look or feel done when you take them out of the oven. Allow to cool on baking sheet, then remove to rack. Makes about 32 cookies.
