Looking for the perfect summer dessert? Claire Saffitz shows you how to make a Peach Upside-Down Cake that's tender, buttery, and full of juicy fruit flavor. Instead of the usual sponge, this recipe uses a touch of coarse-ground polenta for subtle texture and flavor-an old-world twist that makes the cake stand out. In this step-by-step tutorial, Claire walks through how to: • Make a quick polenta-based cake batter with milk, vanilla, and lemon zest. • Caramelize fresh peaches with lemon juice and demerara sugar. • Bake it all together in a Made In Saucier pan for an even golden finish. • Flip the cake upside-down for that show-stopping reveal. Whether you're in Austin, New York, or anywhere peaches are in season, this recipe works beautifully with local fruit. Serve it warm with whipped cream or enjoy it at room temperature as a coffee cake.
