Lost story- Bobbi outgrows the planet

Hey, I figured here might be a good place to ask around to see if anyone can help me with a lost story.  One of my friends is into hyper, and I mean HYPER hyper sizes.  But I can't find the story I was thinking of.

It started with this young woman named Bobbi finding a magic lamp in her grandmother's attic after her passing.  A genie pops out, catlike and rhymes all his sentences, and suggests she wishes big since she only gets three.  So Bobbi wishes to eat everything on the planet, meaning to try all kinds of food, but the genie takes it literally.

Suddenly delivery trucks start showing up.  Buffets drained for her.  When she can't eat people feed her, even set up machines to do it.  The genie mentions that A) she can't make a wish until the first one is COMPLETELY done, and B) genie rules state that she cannot be harmed by the wish, so she should sit back and enjoy the buffet.  Eventually she starts eating everything- cities, busses, draining the oceans dry with a comically large straw.  And finally devouring the planet itself, bit by bit.

She asks the genie where his power comes from, and he states "you silly scamp, it comes from the lamp!" And Bobbi points out she ate the lamp so she has the power now.  It ends with her moving on to take the rest of the solar system as her meal.

Those kinds of astronomical sizes aren't exactly my thing, but that story came back to my memory when discussing with a friend and I really want to show it to them.  If anyone has any leads, let me know!
