Ingredients

Scale

For the Cake

  • 2 cups almond flour
  • 2 whole oranges
  • ⅔ cup honey
  • 3 large eggs
  • ½ teaspoon baking soda
  • 1 cup ground pistachios
  • 1 teaspoon vanilla extract

For the Glaze

  • 2 tablespoons honey
  • ½ cup fresh orange juice

Instructions

  1. Prepare the Oranges: Rinse the whole oranges thoroughly. Place them in a pot of water and boil for about 2 hours until the oranges are very soft. Remove and let them cool.
  2. Blend the Oranges: Slice the cooled boiled oranges into quarters, removing any seeds. Place the slices in a food processor or blender and pulse until they form a smooth puree.
  3. Mix the Batter: In a large mixing bowl, combine the orange puree, almond flour, ground pistachios, honey, eggs, baking soda, and vanilla extract. Mix well until all ingredients are fully incorporated and you have a smooth batter.
  4. Prepare the Pan: Preheat your oven to 350°F (175°C). Grease a 9-inch springform pan or line it with parchment paper.
  5. Bake the Cake: Pour the batter into the prepared pan and smooth the top. Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted in the center comes out clean.
  6. Make the Glaze: While the cake is baking, combine 2 tablespoons of honey and ½ cup fresh orange juice in a small saucepan. Heat gently over low heat until the honey dissolves and the mixture slightly thickens. Remove from heat and let cool slightly.
  7. Glaze the Cake: Once the cake is baked and slightly cooled, remove it from the pan and place it on a serving plate. Drizzle the orange-honey glaze evenly over the top of the cake.
  8. Serve: Allow the glaze to set for about 10 minutes before slicing. Serve the cake at room temperature and enjoy the delightful combination of citrus and nutty flavors.

Notes

  • Boiling the oranges softens their peels and reduces bitterness, essential for a smooth puree.
  • You can substitute honey with maple syrup for a slightly different flavor.
  • Make sure to remove all seeds from the oranges to avoid bitterness in the cake.
  • This cake stores well in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week.
  • For an extra crunch, sprinkle additional chopped pistachios on top before serving.
