Last year pastry chef Joy Cho was developing a recipe that just wasn’t going the way she’d hoped. Then, on a whim, she picked up a new baking pan at the mall and brought it home to play with. To give her mind a break, she began to work on a totally different recipe: a mini Bundt cake. And that’s the origin story of Cho’s wildly popular gem cakes, which disappear from her online shop faster than a newly released vaccine appointment. Note that the flour will create a mottled appearance on the surface of the baked cakes, but once glazed they’ll still look shiny and perfect.
