This recipe was SO good. The only thing I had trouble with was getting the icing to thicken. I ended up using butter to make it more like buttercream and adding a lot more powdered sugar. I think it may have to do with the fact that I used the solid part of a can of coconut milk because I couldn't find coconut cream. Any suggestions on how to fix that? I'd rather not use quite so much extra powdered sugar if it's not necessary.
