So, how exactly did an attempt at making pancakes lead to the destruction of Equestria?

This, along with such things as "Did I put enough vinegar?" or "Nah, They may be slightly overcooked." were the thoughts going through Celestia's mind as she floated through the endless void of space, munching on some good yet slightly crunchy pancakes, the remains of a scorched frying pan still held in her magic.
