These brownies are called "Over the top brownies":
They are characterised by a sweet gooey goodness, according to the recipe. I think your fic is a little like these brownies, Bob: sweet and gooey and just a
leeeeetle over the top! At least compared with the fare you have served us in the past!
But I'm not complaining, and I, too, love the up-side-down floating scene at the end of the fic!
