How to Make Flourless Orange, Pistachio, and Almond Cake

PIN IT

1. Boil the Oranges: Place whole oranges in a saucepan, cover with water, and boil for 1 hour. Drain, cool, then remove any seeds and blend into a smooth purée (peels included!).
2. Preheat Oven: Set oven to 350°F (175°C). Grease and line a 9-inch cake pan.
3. Mix Wet Ingredients: In a large bowl, whisk the eggs and sugar until light and frothy.
4. Add Orange & Dry Ingredients: Stir in the orange purée, then add almond flour, pistachios, baking powder, and salt. Mix until just combined.
5. Bake: Pour into prepared pan and bake 50–60 minutes or until golden and a toothpick inserted comes out clean.
6. Cool & Garnish: Let cool in pan 10 minutes. Remove and dust with powdered sugar and extra pistachios before serving.

What to Serve With It

• A dollop of Greek yogurt or whipped cream
• Espresso or cardamom tea
• A drizzle of orange blossom honey
