  • Grease an 8 inch spring form pan and preheat oven to 350 degrees.
  • Place your egg whites and cream of tartar in a stand mixer and mix until stiff peaks form. Set aside.
  • Place your yolks in another bowl and whisk with vanilla extract, liquid stevia and lemon zest.
  • In another bowl whisk together the remaining dry ingredients.
  • Combine the yolks and dry ingredients together until smooth.
  • In small portions a little at a time, fold the egg whites into the yolk and flour mixture, be careful not to over mix and deflate your egg whites.
  • Drizzle the melted, cooled butter on the side of the bowl to slowly fold it into the batter.
  • Pour batter into pan and bake 30 minutes or until golden on top and a toothpick in center comes out clean.
  • Allow to cool completely before removing and adding optional toppings.
  • Keep refrigerated.
