The cake's in-game description
Snow White: Is this what they call a cake? It looks delicious. Let me try.
Nayuta: Hold thee fast, White Snow. A cake is such a thing that the more exquisite its decorations be, the more delightful is its taste.
Snow White: Decorations? What kind?
Nayuta: Folk oft do add garnishes, or e'en inedible ornaments—so long as they be objects of beauty or affection.
Snow White: We don't need inedible stuff. Let's add garnishes.
Nayuta: Well then, I shall fetch the centipede dumpling White Snow did hide, and place it atop.
Rapunzel: Argh...

Rapunzel: T-this is...! I only just managed to obtain it... The limited-edition side story of that passionate, reckless tale! With the cake's icing all over it, I can imagine things all the more vividly...! Ah... Ahh!
Snow White: We don't need stuff we can't eat. Throw them.
Scarlet: ...
Nayuta: Finally, Young Lady Scarlet.
Scarlet: I... I shall abstain.
Nayuta: And lo, here lieth the numeral ornament we did craft together, in celebration of the third anniversary.
Scarlet: O, this is rather common.
Nayuta: I believe there should be at least one proper item.
Snow White: Can we eat already?
Nayuta: Aye. Young Lady Scarlet, might thou aid in cutting the cake into portions for easier savoring?
Scarlet: Very well. I shall cleave it into four equal parts with precision. Grant me but a moment.
*Clatter*
Scarlet: Hmm... Even the plate lies cloven. It seemeth Fleetly Fading is famished this day.
Snow White: Alright! Time to dig in.
Rapunzel: Be careful not to bite the plate.
Nayuta: ...
