Ingredients
Method
- Preheat the oven to 350°F and prepare an 8-inch round cake pan with nonstick baking spray and a parchment circle.
- Whisk together the flour, cornstarch, baking powder, baking soda, and salt until evenly combined.
- Beat the softened butter, oil, and granulated sugar until light, fluffy, and pale in color.
- Blend in the egg whites, vanilla extract, and sour cream until smooth and fully incorporated.
- Mix the dry ingredients into the batter alternately with the buttermilk, stirring only until no dry streaks remain.
- Transfer the batter into the prepared pan and smooth the surface evenly.
- Bake for 38 to 43 minutes, or until a toothpick inserted into the center comes out clean.
- Cool the cake in the pan for 10 minutes before transferring it to a wire rack to cool completely.
- Combine the peaches, brown sugar, cornstarch, and lemon juice in a large skillet over medium heat and bring the mixture to a gentle simmer.
- Continue cooking while stirring occasionally until the fruit softens slightly and the juices become thick and glossy, about 10 to 15 minutes.
- Transfer the peach mixture to a bowl and refrigerate until thoroughly chilled.
- Beat the softened cream cheese with powdered sugar and the heavy cream until smooth and creamy.
- Whip the cold heavy cream with the remaining powdered sugar and vanilla until it reaches soft peaks.
- Fold in the cream cheese mixture, then beat briefly until stiff peaks form.
- Trim the domed top from the cooled cake with a serrated knife to create a flat surface.
- Spread the whipped cream evenly over the cake and freeze for 15 minutes so it firms up before adding the fruit.
- Drain any excess liquid from the chilled peaches, then spoon them evenly over the whipped cream layer.
- Cover the finished cake and refrigerate until ready to serve. Store leftovers in an airtight container in the refrigerator for up to 5 days.
