Because of MUFFINOMICON

DERPY'S INFINITE MUFFIN SPELL

My comment on the story:

Tenebris vires supra, hoc muffin aeternam! Vos appello, cuius spiritus mortuos muffin aeterna saecula Ita fiet;!"

Thats perfect latin!

it translates into...
"The dark forces of the above, this eternal muffins! I call upon you, muffins, whose breath is eternal ages of the dead, So shall it be;! "

She probably will over time gain short bursts of infinite Dark powers from taking bites of the muffin

Which also means her muffins are now powered by dark/elder gods (I.E. Cthulhu, Hastur, Khorne, Slaanesh ,Hades And Zalgo)

replace dead with bread and we are golden

Uhh slaanesh's domain is Ecstasy and pleasure Whereas slaneesh's is sex and orgies

Anotherwords Derpy makes muffins that would push alot of PEOPLE/PONIES into ecstasy and they are pleasure of the mouth

Tenebris vires supra, hoc muffins aeterna! Vos appello, muffins cuius spiritus in aeterna saecula panibus erunt

ROugh translation

The dark forces of the above, this eternal muffins! I call upon you, muffins, whose breath is eternal ages of the bread, So shall it be!
