Orange Upside-Down Cake

Ingredients

1 pound (454 grams) small navel oranges, blood oranges, Cara Cara oranges, or a combination (2 to 3 oranges), divided10 tablespoons unsalted butter, melted, divided1½ cups (10½ ounces/298 grams) sugar, divided1 teaspoon cornstarch ⅛ teaspoon plus ½ teaspoon table salt, divided1 cup (5 ounces/142 grams) all-purpose flour 1 teaspoon baking powder ½ cup sour cream 2 large eggs 1 teaspoon vanilla extract 2 tablespoons orange marmalade

Before You Begin

For the most striking visual, we like to use a combination of navel oranges, blood oranges, and Cara Cara oranges. Look for oranges no larger than a tennis ball; you'll be able to use more slices and cover a greater area. Peel the oranges by hand instead of with a knife: Leaving the exterior membrane intact helps maintain a circular shape. We recommend using a serrated knife to slice this cake to get clean slices. Serve the cake with whipped cream, if desired.

Instructions

  1.  Adjust oven rack to middle position and heat oven to 350 degrees. Grease 9-inch round cake pan, line with parchment paper, then grease parchment. Grate 2 teaspoons zest from 1 orange; set aside. Using your hands, peel oranges. Using sharp chef's knife or serrated knife, trim ends and slice oranges crosswise ¼ inch thick, removing any seeds.
  2.  Pour 4 tablespoons melted butter over bottom of prepared pan and swirl to evenly coat. Whisk ½ cup sugar, cornstarch, and ⅛ teaspoon salt together in bowl, then sprinkle evenly over melted butter in pan. Arrange orange slices in single layer over sugar mixture, nestling slices snugly together and pressing them flat (you may have fruit left over).
  3.  Whisk flour, baking powder, and remaining ½ teaspoon salt together in large bowl. Whisk sour cream, eggs, vanilla, orange zest, and remaining 1 cup sugar in second large bowl until smooth, about 1 minute. Whisk remaining 6 tablespoons melted butter into sour cream mixture until combined. Add flour mixture and whisk until just combined.
  4.  Pour batter over oranges in pan and smooth top with rubber spatula. Bake until deep golden brown and toothpick inserted in center comes out clean, 50 to 55 minutes.
  5.  Let cake cool in pan on wire rack for 20 minutes. Run knife around edge of pan to loosen cake, then invert cake onto serving platter. Discard parchment. Let cake cool for at least 1 hour.
  6.  Microwave marmalade in bowl until fluid, about 20 seconds. Using pastry brush, brush marmalade over top of cake. Serve.

Why This Recipe Works

We were after a sturdy, buttery cake crowned with jewellike rounds of fresh citrus fruit swathed in a sticky glaze. Peeling the oranges by hand (instead of cutting away the peel and pith with a knife) ensured perfectly round slices. We used white sugar in the fruit layer (instead of commonly used brown sugar or a caramel) for a cleaner taste that didn't obstruct the subtle floral flavor of the oranges. Cornstarch helped trap the excess juices and prevent a soggy cake. A thin layer of orange marmalade brushed over the cooled cake made for an extra-shiny and extra-citrusy finish.
