Comic Book Resources has tossed up the extended preview to My Little Pony: Friends Forever #22. For those of interested in seeing what other ingredients besides flour, cake mix, something sweet not sour, a pinch of salt, and a teaspoon of vanilla are added to the cake Celestia and Pinkie cook up, you can find it after the break!
For some reason, I get the feeling that the special ingredient is bananas. Though I can't quite put my finger on it.
Anyways, special thanks to Chevistian1, Masem, and everyone else who sent it in!
