Step 1

Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Grease and flour a 9x5 loaf pan or line it with parchment paper for easy removal.

Step 2

In a blender, combine the whole seedless navel orange (quartered and seeds removed), eggs, olive oil, granulated sugar, sour cream, and vanilla. Process the mixture until smooth. Be careful not to over-blend.

Step 3

Add the dry ingredients to the blender. Pulse the blender just a few times until the dry ingredients are incorporated into the wet mixture. Do not overmix.

Step 4

Pour the batter into the prepared loaf pan.

Step 5

Bake the cake in the preheated oven for 50-55 minutes, or until a toothpick inserted into the center comes out clean and the top is golden brown.

Step 6

Once baked, remove the cake from the oven and let it cool in the pan for about 10 minutes. Then, transfer it to a wire rack to cool completely.

Step 7

Once the cake has cooled, you can serve it as is or dust it with powdered sugar for decoration.

Step 8

Combine powdered sugar and orange juice until smooth.

Step 9

Pour the glaze over the cake.
