Add the oil, sugar, eggs, and vanilla to a blender and blend for 20-30 seconds (do not over blend).
Pour the blended mixture into a bowl and mix in the orange zest, lemon juice, and orange juice.
Add ½ of the flour and mix.
Now, add the other ½ of the flour + the baking powder. Mix until combined.
Pour the batter into a loaf pan that is lined with parchment paper.
Bake at 350F for 25-30 minutes (depending on the oven) or until a toothpick comes out clean.
