I would just internet google "sugar free red velvet cake" recipe and see what you get. I've never tried Sugar Free for a red velvet cake. I wondered how good it would taste with the red dye and sugar substitute.
If you make it, let us know how it turned out.
(PS: just an fyi, having CAPS on looks like you are SHOUTING. )
Love the SPS system....See Leah's tagline for instructions.
