Here is a link that I found off of cake central. They use a high density foam paint roller to smooth out buttercream on cakes. I havnt tried it but it looks awsome! The above link gives the detailed instructions. Pretty simple though.
If you havnt gotten this book from the library, then you are really missing out. It is fantastic. It is by Kerry Vincent. She needs no introduction Her work is flawless. She has some things in there that I would have never thought possible. So cool. For one of her cakes she makes her own silicone mold to make the jewels that you see on the cover (above). Genius! Gabby and I tried out her fondant recipie. Loved it! (Dont make it when its raining. Doesnt work as well) It takes the same amount of work as the MMF but has a much better texture. We are definatly not going back to MMF after this. The plus about this one is that the fondant will stiffen if left to dry. The MMF wont. Plus you can use it right away but its better if you leave it overnight. Heres the recipie for anyone who wants to try it.
I felt like experimenting after having a Mango Raspberry smoothie and wanted to try and translate it into a cupcake. So I made white cupcakes with raspberries and made this frosting. It turned out good.
