It's my DS's first birthday party and I have baked a cake. So obsessed with the baking was I that I forgot to think about the icing! I have made a creme fraiche and lemon curd filling which is delish, but now I'm a bit unsure what to put on top. Can i just make butter icing? With vanilla? Or is this a bad mix of flavours? Shall I just do some more creme fraiche stuff?? There has to be something as I want to decorate it with a big smiley face.
Please? Thanks!
PS I'm a beginner, so talk slowly!
