One of my first cake decorating efforts since Wilton I, and first attempt at cornellis. It was a 4 layer, 10 inch cake : yellow cake, choc. cream cheese filling, choc. cake, vanilla cream cheese filling, choc cake, choc. filling, yellow cake. It was frosted with ganache. Whipped the BC decorator frosting a bit too much and it got kind of feathered. I'd like to get better at this, so please leave a helpful tip. What would you have done differently?
