Pineapple Upside-Down Cake With Blueberries

This Pineapple Upside-Down Cake with Blueberries is a fun, fruity twist on the classic—caramelized brown sugar on top, juicy pineapple, and bursts of blueberries in every slice. It bakes up soft and buttery with a bright, summery flavor that feels a little tropical (but still cozy and familiar). Just layer the fruit, mix the batter, bake, then flip for that glossy, bakery-style finish.
