1 c. unsalted butter, room temperature
1 c. sugar
1 c. light brown sugar, packed
2 large eggs
2 tsp. vanilla
2 1/4 c. all-purpose flour
3/4 c. unsweetened cocoa powder
1 tsp. baking soda
1 tsp. salt
1 (11 oz.) bag confetti baking chips (about 2 cups)
Preheat oven to 350 degrees. In a large bowl, cream together butter, sugar and brown sugar for two minutes. Scrape down the bowl and add the eggs, one at a time, beating well after each addition and mix until light and fluffy. Mix in the vanilla. In a separate bowl, combine the flour, cocoa, baking soda and salt and gradually mix into wet mixture. Mix until just combined. Stir in confetti chips. Spray cookie sheets with cooking spray.
Form dough into roughly 1 1/2- 2 inch balls (I like to use a 1 3/4 Tablespoon cookie scoop). Place dough balls on cookie sheet, leaving 2-inches between each. Bake for 8-9 minutes or until tops of cookies start to crack (mine are perfect at 9 minutes). Remove from oven and transfer cookies to a wire cooling rack and cool completely. Repeat with remaining cookie dough. Makes around 40 cookies.
