A quick and easy peach upside-down skillet cake with caramelized peaches and a luscious salted caramel sauce, perfect for comforting desserts or summer gatherings.
Use fresh peaches for best texture and flavor. If using canned or frozen peaches, drain and pat dry to prevent sogginess., Keep heat medium-low when making caramel to avoid burning or graininess; stir gently and remove from heat once smooth., Cake can be made ahead, cooled, and refrigerated up to 3 days; warm before serving and refresh with salted caramel drizzle., If you don’t have a cast iron skillet, an oven-safe nonstick or stainless steel skillet or baking dish will work, but caramel crust may be less deep., For vegan version, swap butter for vegan margarine or coconut oil, use plant-based milk, and substitute egg with flax egg., Peach peeling tip: score ‘X’ on bottom, blanch in boiling water for 30-60 seconds, then ice water bath to slip off skins easily., Leftovers reheat well in a 300°F oven or microwave for 20-30 seconds., This recipe is adaptable: swap peaches for nectarines, pears, or apples, and try different flours and milks for dietary needs.
