1. Add the eggs and sugar. Beat until high and fluffy. If you are using a hand mixer beat for 20 minutes. Beat really well!
2. At this point add in the lemon juice and mix again. Then add potato starch and baking powder. Mix till blended really well.
3. Bake at 350 degrees Fahrenheit. You can use any type of pan. Bake until golden on top and a toothpick comes out clean. Let the cake cool, then frost. Enjoy!!
