I have a book on my shelf called "Fantastic Food with Splenda" by Marlene Koch (says 'the author of Unbelievable Desserts with Splenda')
I have NEVER made anything form this book, but would be glad to share some of the recipes with you. It lists 18 recipes n the index under Cake
I also have a book titled "Baking with Splenda" by JoAnna M Lund, again, never used. There seems to be about 40 listed under 'cake'
They seem to have the simple, to the 'more things added' type
Are you looking for a 'basic yellow' cake, or something a bit more?
These books could not have been that expensive, or I wouldn't have bought them!
