Pre-heat oven to 350F (180C). Grease and flour a 9 inch cake pan or 9-10 inch bundt pan.
In a medium bowl whisk together the flour, baking powder and salt. Set aside.
In the mixing bowl beat the egg yolks and sugar until light and fluffy approximately 5 minutes. Add the milk, oil, zest and juice beat to combine.
Beat in the flour a little at a time, beating between each addition. Beat until smooth 1-2 minutes. Transfer to the prepared pan and bake for approximately 30 minutes. Test for doneness with a toothpick. Let cool in the pan then move to a plate. Dust with powdered sugar before serving. Enjoy!
