We also had leftover icing from a sleepover
We mixed up a batch, after I sliced up the zucchini, and baked it up. I don't know why, but for some reason I expected the whoopie pies to be fairly tricky, but it was surprisingly easy to make.
We ended up with about twenty of them. I wasn't really expecting them to be great. Again, I'm not sure why as I like zucchini bread. Let me tell you people, these things are AMAAAAA-ZING!!! SO good! Ugh. I am going to hear them whispering to me, from the kitchen, until they are gone.
If you want to take a stab at making your own Zucchini Woopie Pies you can find the recipe here at Bakeaholic Mama.
