A tender, caramelized upside-down cake made with ripe peaches and brown sugar, baked in a cast iron skillet for a sticky, butterscotch-like topping. This easy summer dessert comes together in minutes and is perfect for brunch or dessert.
Use ripe but firm peaches—overripe peaches will make the cake soggy. Room temperature ingredients are crucial for proper creaming and texture. The 10-minute cooling time before flipping is essential; too short and topping won’t set, too long and caramel will harden and stick. For best results, use a kitchen scale to measure flour (180g for 1½ cups). Leftovers keep at room temperature for up to 2 days, covered loosely. Freezes well for up to 3 months.
