Ingredients

  • 1 cup pistachios, shelled: These nutty gems provide a lovely texture and taste.
  • 1 cup granulated sugar: Sweetens the cake perfectly.
  • 6 large eggs: Bind everything together and create a fluffy texture.

How to Make Flourless Orange Pistachio Cake

  1. Preheat the oven to 350°F (175°C). Grease and line an 8-inch round cake pan with parchment paper.
  2. Place the whole oranges in a pot, cover with water, and bring to a boil. Reduce heat and simmer for about 1 hour until soft. Drain and let cool.
  3. Once cooled, cut the oranges in half and remove any seeds. Place the oranges in a food processor and blend until smooth.
  4. In a separate bowl, finely grind the pistachios until they resemble a coarse meal.
  5. In a large mixing bowl, combine the orange puree, ground pistachios, sugar, eggs, baking powder, and salt. Mix until well combined.
  6. Pour the batter into the prepared cake pan and smooth the top.
  7. Bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean.
  8. Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
  9. Dust with powdered sugar before serving, if desired.

Substitutions & Additions

  • If you’re not a fan of pistachios, try using almonds or walnuts for a different flavor.
  • Add a splash of vanilla extract to the batter for an extra layer of sweetness.
  • For a richer flavor, consider adding a tablespoon of orange zest.

Tips for Success

  • Make sure to blend the oranges until completely smooth for the best texture.
  • Don’t skip the cooling time; it helps the cake set properly.
  • If the cake sinks a little in the middle, don’t worry! It will still taste delicious.
