This is what you will need:
1 cup unsalted butter
1 cup white sugar
3/4 cup packed brown sugar
1 1/4 cups unsweetened cocoa powder
1 3/4 cups all-purpose flour
2 tsp baking soda
2 cups white chocolate chips
Preheat oven to 350 degrees F.
In a large bowl, cream together the butter, brown sugar and white sugar until light and fluffy.
Add the eggs one at a time, beating well with each addition.
Combine the cocoa, flour, and baking soda, gradually stir into the creamed mixture.
Fold in white chocolate chips.
Drop by rounded spoonfuls onto greased cookie sheets.
Bake for 8 to 10 minutes, until puffy but still soft.
Allow cookies to cool on baking sheet for 5 minutes before removing to a wire rack to cool completely.
NOTE: If you like chocolate and mint together, I did half a batch with Mint Chocolate M&Ms and the other half with White Chocolate Chips.
