Pre-heat oven to 350F (180C), grease and flour an 8 or 9 inch cake (20-23 cm)
In a small bowl whisk together the flour and baking powder.
In a large bowl beat on low to medium speed (low is best but no higher then medium speed) sugar and eggs until very fluffy and light. Approximately 5 minutes.
Then add the zest, juice, oil and milk, beat until combined. Then add the flour mixture and beat on low speed until smooth.
Pour into prepared cake pan and bake for approximately 40 minutes or until toothpick comes out clean. Let cool in pan then remove to a cake plate.
Let cool completely before dusting with powdered / icing sugar. Enjoy!
**All tablespoons (and teaspoon) are level not heaping.
Eggs and sugar should be beaten on low speed, never on high speed. When adding the flour mix on low speed.If you are having trouble with this cake, a reader mentioned beating the flour into the mixture by hand instead of with a mixer. A whisk or spatula would work for this.Be sure to watch the Video at the top of the post!
