To prepare a supreme chocolate mint chip cookies baked goods recipe, you will first need to prepare your ingredients. You will need: 14 cup chocolate chips, 1 teaspoon vanilla extract, and 2 tablespoons butter. Preheat the oven to 350 degrees F (180 degrees C) and grease two 9-inch round baking pans with non-stick cooking spray. Set aside. Sift together the flour, cocoa, baking powder, salt and baking soda. Add the dry ingredients to the wet ingredients and mix until just combined. Pour the chocolate mixture into the greased and floured pan. Bake the cookies for 12 to 15 minutes or until the edges are golden brown. Remove from oven and allow to cool before cutting into squares.
