When I made these cookies, I used one of those Pampered Chef Cookie Scoops. The smaller cookie scoop to be exact. It was the Tablespoon size cookie scoop. I was able to make 45 cookies. Each cookie was between 2 to 2-1/4 inch in size.
Photo of the cookies which I had made years ago, with an (18.25 ounce) boxed yellow cake mix. Now-a-days the boxed cake mixes have been reduced in size to (15.25 ounces), so now I've adjust the amount of ingredients used to make these cookies.
