Dairy free frosting

Cream Cheese style Dairy free Buttercream Normally I don't do butter cream or frosting, what ever you want to call it. I have trouble getting over the fact that it's just fat and sugar. I also find it way too sweet, and over dosing on sugar is not really great for my IBS. I get windy pops - which lead's to swollen tummy - and worst case scenario stomach spasms The rest of my family and friends love it though. If I want my baking to be as good as or better than the full fat dairy am going to have to master it. I also need to make my baking look a lot more pretty..... It's out there Iv said it, I don't do pretty fancy decorated baking. Which is really strange as I'm into arts and crafts!!! The guys at work have offered to be taste testers, so I used a Wacky cake recipe to make some cupcakes. You can't really make butter cream, with out baking something for it to go on...... I reduced the fat by using soya ...
