Anyone who's read Rat Queens knows that Betty, like most everyone, loves her some candy. And spoiler alert: I love Betty. On at least two separate occasions, she's put in charge of food, both times providing only candy and drugs. When mixing a cocktail at their party, she charmingly says, "Booze and candy! Two out of three of my favorite things in life, poured in a glass! I'd mix in the third thing, but I've yet to figure out how to make an orgasm an ingredient."
So, clearly, she's my best friend.
Anyways, the food. Obviously, I needed to have something with candy so that Betty will love me as much as I love her. Betty also talks about mushrooms (likely of the hallucinoginic variety) an awful lot, even going to pick mushrooms while questing, so I considered a mushroom themed meal. There's also candy apple martinis. And, at one point, Betty whips up some flapjacks. But, ultimately, it seems that Betty's truest love is candy, so what better way to celebrate her and the Rat Queens than with a candy cake?
