A tender, nutty brown butter cake topped with caramelized fresh peaches, made in a cast iron skillet for a rustic, flavorful dessert perfect for summer gatherings.
Watch the butter carefully when browning to avoid burning. Use fresh peaches for best caramelization and texture. If peaches are very ripe and soft, reduce caramelizing time to prevent mushiness. For gluten-free, substitute flour with 1:1 gluten-free baking flour. Vegan version can be made using browned coconut oil, flax egg, and plant-based milk. Use a heavy oven-safe nonstick skillet if cast iron is unavailable, lining with parchment paper for easier cleanup.
