The cake mix box says that the mix should make 24 cupcakes. This was not the case for me. It only made 15 cupcakes for me and I didn't overfill the cups. I think when you are using this baking technique there isn't as much batter as when you make the cake mix traditionally.
You could also make mini muffins, but you will need to adjust the baking time accordingly.
I calculated that these muffins are 5 points each if you make 15 muffins for the green, blue and purple myWW plans.
