What does addding pudding to cake mix do? If I add pudding into the mix do I have to add any extra liquid or adjust the cooking time?

Makes it super moist and yummy! I usually add a smidge more water if the mix seems a little dry.

would it make the Giant Cupcake sturdier or should I use the WASC? Will I need to adjust my cooking time if I use the giant cupcake pan because it's so deep?

Sorry, I'm not sure because I've never used it. BUT, I would think it wouldn't matter.
