Helpful Recipe Tips

  • Cannot sub out almond flour or coconut flour. They are working together in this recipe. For a coconut flour only recipe see here. For an almond flour only recipe click here.
  • Use lemon flavor or emulsion instead of lemon extract. This will give you the best lemon flavor over lemon extract. The extract just doesn't perform well for a great flavor. Use it if you'd like but I recommend the flavor at the link.
