# What You'll Need:
→ Wet Ingredients
01 - 1 large seedless orange, washed and quartered
02 - 3 large eggs
03 - 2/3 cup vegetable oil (sunflower or canola)
04 - 1 teaspoon vanilla extract
→ Dry Ingredients
05 - 1 1/4 cups granulated sugar
06 - 2 cups all-purpose flour
07 - 2 teaspoons baking powder
08 - 1/2 teaspoon salt
→ Optional Topping
09 - Powdered sugar, for dusting (optional)
# Method:
01 - Preheat the oven to 350°F. Grease a 9-inch round cake pan and line the bottom with parchment paper.
02 - Place the quartered whole orange (including peel), eggs, oil and vanilla in a blender and process until completely smooth with no large pieces remaining.
03 - In a large bowl, whisk together the granulated sugar, all-purpose flour, baking powder and salt until evenly distributed.
04 - Pour the orange puree into the dry mixture and fold gently with a spatula or whisk until just combined; avoid overmixing to keep the crumb tender.
05 - Scrape the batter into the prepared pan and smooth the surface with an offset spatula or the back of a spoon.
06 - Bake on the center rack for 45–50 minutes, or until a toothpick inserted in the center comes out clean and the top is golden brown.
07 - Let the cake rest in the pan for 10 minutes, then invert onto a wire rack and cool completely.
08 - If desired, dust the cooled cake lightly with powdered sugar before slicing. Serve plain or with whipped cream or vanilla ice cream.
