looking for a recipe for a vanilla cake but sugar freee OR can use spenda,at customer request.can anyone help? need cake soon!

Have you checked the recipes on this site? You can also look thru the Splenda site recipes. I have also heard some good things about agave. Whatever you decide be sure to bake it and let the client have a taste before d-day. If she is just dieting and not really used to diabetic sweets she may change her mind.
