The Heartbreak Bakery by A.R. Capetta

'What's done is done.' Unless, of course, it was done by my brownies. Then it's getting undone. Syd (no pronouns, please) has always dealt with big, hard-to-talk-about things by baking. Being dumped is no different, except now Syd is baking at the Proud Muffin, a queer bakery and community space in Austin. And everyone who eats Syd's breakup brownies . . . breaks up. Even Vin and Alec, who own the Proud Muffin. And their breakup might take the bakery down with it. Being dumped is one thing; causing ripples of queer heartbreak through the community is another. But the cute bike delivery person, Harley (he or they, check the pronoun pin, it's probably on the messenger bag), believes Syd about the magic baking. And Harley believes Syd's magical baking can fix things, too-one recipe at a time
