Cookies and Cream Brownie Ingredients

Notes
- This recipe was tested with a 9 X 9″ square pan. It’s my favorite for brownies. If using an 8 X 8 pan, add 5 minutes for baking time. It will seem underbaked at first, but will continue baking in the pan while cooling.
- This recipe tastes great after the chilling time.
