Have you got lots of leftover creme fraiche that you don't know what to do with? And to make it worse you have cupcakes in the oven and you haven't had time to buy some frosting! Well with this recipe you can solve both dilemmas with only 3 ingredients! Sorry the measures aren't exact, it all depends on how much creme fraiche you have left.
If your making chocolate frosting, I'd recommend adding some more icing sugar/sweetener/sugar as cocoa powder can be very bitter!
Vanilla extract, strawberry flavouring, orange/lemon zest, cocoa powder,etc
