I know, I know but my mum is coming on sunday and all she wants apparently is "a nice slice of cake". She's diabetic with quite significant issues with her feet and isn't supposed to have it. I've found a betty crocker sugar free mix in tesco but I haven't made a cake with a packet mix for years and I'm suspicious that it will taste artificial and I'm completely stumped at how to ice it. Id generally do butter cream. She doesn't like fresh cream.
Any ideas?
