Blood Orange & Corn Flour Ricotta Cake with Whipped Mascarpone {gluten-free}

Corn flour gives this cake a golden hue while ricotta adds tenderness and chew. Topped with mascarpone and blood oranges, it makes a bright treat for the depths of winter.

Ingredients

Cake:

  • 1 teaspoon butter for greasing the pan
  • ¾ cup + 2 tablespoons organic granulated cane sugar, (175 g)
  • finely grated zest of 1 large blood orange and 1 large lemon (preferably meyer)
  • 1 vanilla bean, split lengthwise and scraped
  • 3 large eggs
  • cups best-quality whole-milk ricotta (I like this one), (12 ounces, 340 g)
  • 8 tablespoons unsalted butter, melted, (113 g)
  • ½ cup sweet white rice flour, (80 g)
  • ½ cup corn flour (i.e. very finely ground cornmeal, NOT cornstarch), (75 g)
  • ½ cup oat flour, (50 g)
  • 2 teaspoons baking powder
  • ½ teaspoon fine sea salt

For serving:

  • 1 cup heavy whipping cream, (120 ml)
  • ½ cup mascarpone, (4 ounces, 113 g)
  • 1 tablespoon organic granulated cane sugar
  • seeds from ½ vanilla bean , (or ½ teaspoon vanilla extract)
  • 4 large blood oranges

Instructions

  • Position a rack in the center of the oven and preheat to 350ºF. Butter an 8-inch cake pan and line the bottom with a round of parchment paper.
  • Place the sugar in a large bowl and add the citrus zest and vanilla pod and scrapings. Rub the zest and vanilla seeds into the sugar to moisten and distribute. Remove the vanilla pod and reserve for another use. Beat the eggs into the sugar mixture, then the ricotta, and finally the butter. Place a strainer over the bowl and add the sweet rice, oat and corn flours with the baking powder and salt. Sift in and stir until well-combined.
  • Scrape the batter into the prepared pan, smooth the top, and bake until golden on top and a tester comes out clean, 50-60 minutes. Let cool until warm, then invert the cake onto a plate, peel away the parchment, and flip right side-up. Let cool completely unless serving warm.
  • To prepare the topping, whip together the cream, mascarpone, sugar and vanilla seeds or extract until the mixture just holds firm peaks. (If you overwhip and the mixture starts to look grainy, you can rescue it by folding in a few tablespoons of cream until it loosens up.) Chill until needed.
  • Prepare the oranges by cutting off ½-inch from each end. Place a cut side down and use a sharp knife (I like a small serrated knife) to pare away the peel and white pith, following the curve of the fruit. Turn the orange on its side and slice into rounds 3/8-inch thick. Repeat with the remaining oranges.
  • Dollop and spread the whipped mascarpone all over the top of the cake leaving a 1-inch border. Drain the orange rounds and place atop the cake in overlapping circles. Serve the cake right away, using a large serrated knife to cut slices (they will be messy – go with it). Extra cake will keep refrigerated airtight for up to a day or two.

Notes

Cake adapted from Bon Appétit.
You can bake the cake in a 9-inch pan for a flatter cake; decrease the baking time by 5-10 minutes.
You'll want to finish the cake at the last minute, so that the cake is room temperature and the cream is cold. It will hold up for an hour at cool room temperature. Alternatively, dust the cake with powdered sugar and serve wedges of still-warm cake on plates with a dollop of whipped mascarpone and a few rounds of blood orange to the side.
The cake can be made up to 1 day ahead and stored airtight at room temperature.
