Method
Prepare the peaches and caramel
- Peel and slice the peaches and toss with lemon juice and 2 tablespoons sugar; let sit 10–15 minutes, then drain and pat dry.
- Melt 4 tablespoons butter in a medium skillet over medium heat; add 1/3 cup light brown sugar, 1/4 teaspoon salt, and 1/2 teaspoon cinnamon and cook, stirring, until bubbling and slightly thickened, about 2–3 minutes; remove from heat and stir in 1/2 teaspoon vanilla.
- Pour the warm caramel into a lightly buttered 9-inch pan and arrange the peach slices in a tight concentric pattern.
Make the batter
- Preheat oven to 350°F. Brown 6 tablespoons butter in a small saucepan until nutty, about 4–5 minutes, then let cool 3 minutes.
- Whisk together 1 1/4 cups flour, 1 1/2 teaspoons baking powder, and 1/4 teaspoon salt in a bowl.
- In a large bowl, beat 2 eggs with 3/4 cup sugar until pale; whisk in the cooled browned butter, 1/3 cup sour cream, and 1 teaspoon vanilla. Fold in dry ingredients until just combined; add 1 tablespoon milk only if batter is too stiff.
Bake and finish
- Gently pour batter over arranged peaches, smoothing the top carefully, and bake at 350°F for 38–45 minutes until golden and a toothpick comes out with a few moist crumbs.
- Cool in the pan on a wire rack for 10 minutes, run a knife around the edge, then invert onto a serving plate; cool another 10 minutes before slicing. Reposition any peaches that stuck to the pan.
Notes
Use ripe but firm peaches and pat them dry after macerating to avoid a soggy cake. Line the pan bottom with parchment if using a springform to make inversion easier. Store covered at room temperature up to 2 days or refrigerate up to 4 days; rewarm slices in a 300°F oven for 10–12 minutes to refresh the caramel.
