Before this thread cake making really wasn't a part of my daily interest, but I thought I'd buy a few cake mixes to see what they were like. First I bought a cheap Waitrose sponge cake mix and whipped some thick cream and some chopped up fresh strawberries and made a sort of Victoria Sponge - and it was really good. I have also tried some other mixes .... today a toffee cake mix. What I liked about using a premix is that you can take just a 100gms of mix and scale down the water and oil and make a couple of fresh muffins in around 20 to 30 minutes or so. I like the idea of just making wifey and me a muffin size cake each and premixes seem to me to be a perfectly acceptable method.
I have convinced wifey to get stuck into scratch cake making and bought her the Mary Berry book, but mean time a daily muffin sized cake is a nice idea.
Thanks to the OP for sowing the seeds of my muffin stuffings.
