Pour into the blender, your eggs, oil, and sugar and chopped orange.
Blend the mixture until smooth and pour it into a bowl.
Add in the flour, baking powder, and baking soda into your mixture. Stir with a spatula or whisk until just combined. Slowly drizzle in the milk while stirring to loosen up the batter.
Grease your baking dish well, pour in the batter and bake at 180ºC (356ºF) for 35 minutes.
