Just wondering if anyone has any good receipes for kids muffins?

DS is so fussy, wont eat vegetables or much fruit (will only eat banana). A girlfriend of mine made some carrot and zucchini ones the other day and DS loved them. They werent too bad actually, sweet enough, she put some cinnamon sugar on them and they tasted great.

So just wondering if anyone has some similar receipes i can make for DS.. would be a great way to get him some hidden vegies!

TIA.
