Ingredients

  • 200 g unsalted butter softened at room temperature
  • 200 g granulated sugar
  • 200 g almond flour finely ground
  • 100 g coarse cornmeal polenta not instant
  • 1.5 tsp baking powder ensure gluten-free if necessary
  • 3 large eggs beaten
  • 2 large blood oranges zested and juiced
  • 100 g powdered sugar for the glaze
  • 1 tsp vanilla extract

Notes

Storage: Store in an airtight container at room temperature for up to 3 days or refrigerate for 5 days. Make-ahead: This cake actually tastes better the second day as the citrus syrup fully hydrates the polenta. Variation: If blood oranges are out of season, Cara Cara oranges or regular Navel oranges work perfectly.
