A regular size cookie scoop is 2 Tbs, and it takes about a scoop and a half to fill each space. I love this tip so much that I just bought this large cookie scoop (3 Tbs) to make it even better. One scoop is perfect for each muffin. They should just call it a muffin scoop. Just look at this nicely cleaned out bowl - all I did was use my large scoop 12 times. Mmmm... I might have to go bake muffins now.
