Nectarines or peaches play so nicely with the warm flavor of brown sugar in this simple sheet cake. Add a little browned butter glaze for an out of this world flavor combination!
Preheat the oven to 375°F and grease a 13x18x1-inch half sheet cake pan.
Wash 3 peaches or nectarines and thinly slice or dice.
In a bowl, toss peach slices/cubes with 1 teaspoon cornstarch and 1 teaspoon ground cinnamon. Set aside.
In a large saucepan over medium heat, bring 1 cup butter, 1 cup granulated sugar, 1 cup light brown sugar, and 1 cup water to a boil. Remove from heat.
Whisk in 2 eggs, ½ cup plain yogurt, 2 cups all purpose flour, 1 teaspoon almond extract, 1 teaspoon vanilla extract, 1 teaspoon baking soda, and 1 teaspoon salt until just combined. Spread in prepared pan.
Arrange sliced peaches over cake batter.
Bake for 25-30 minutes or until cake is done (the cake will bake darker than you are used to due to the brown sugar. Test the cake and don't go by color.)
Cool most of the way and then drizzle with brown butter glaze, or dust with powdered sugar.
