1. Boil the Oranges:

– Start by placing the whole oranges (skin, pith, and all) into a pot of water. Bring it to a boil and let the oranges cook for about 1 hour. This softens the peel and enhances the flavor.

– Once boiled, remove the oranges from the water and allow them to cool down.

2. Blend the Oranges:

– Cut the cooled oranges in half and remove any seeds. Then, place them in a food processor or blender and blend until smooth. Set the orange purée aside.

3. Prepare the Cake Batter:

– Preheat your oven to 350°F (175°C) and grease a round 9-inch cake pan with a bit of butter or non-stick spray.

– In a large mixing bowl, whisk the eggs and sugar together until light and fluffy. This will give the cake a nice texture.

– Add in the orange purée, vanilla extract, almond flour, baking powder, and a pinch of salt. Stir until everything is well combined.

4. Bake the Cake:

– Pour the batter into your prepared cake pan and spread it evenly.

– Bake for about 45–50 minutes, or until a toothpick inserted into the center comes out clean.

– Once baked, allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.

5. Serve:

– Once cooled, dust the top with powdered sugar or garnish with fresh whipped cream and orange slices, if desired.

– Slice and enjoy!
