We did discover these yummy recipes (via Pinterest)! Given all the limitations, a yummy treat with a veggie or a fruit in it is a magical find.
Frosted Zucchini Bread Muffins by MIH (Mommy I'm Hungry)
We modified the recipe to be gluten free by using gluten free all purpose flour.
One bit of warning that it does make a BUNCH of muffins...we had enough for 19 muffins! Oh my!
Banana Cream Caramel Dessert by Glorious Treats
(photo is from their site...we ate ours too fast for a photo!)
We modified it by using soy milk.
