I'm new here and also a beginner in baking.
making new year small muffins and I have a problem with my frosting.
I'm using this recipe http://2.bp.blogspot.com/-2uqGXvKq-I0/TtumVoa3cLI/AAAAAAAACDU/wL9QA0B8XjQ/s1600/65724475781568604_m1f5BNFa_c.jpg
I forgot to sift the powdered sugar. I don't know if that's the problem or something else but my buttercream doesn't turn to be "nice and fluffy". It is also a bit thin..
So can anybody pleaaaase give me any tip, how can I fix that??
Thanks in advance.
