Yellow roses are suppose to represent friendship and I believe this cake is very friendly.
I mean, who would not want to be friends with a chocolate cake with light yellow buttercream? The chocolate cake was one of my favorites-One Bowl Chocolate Cake. I'm not sure why it's called "one bowl" because you really use 2 but I don't question Martha's methods. I modified my favorite buttercream recipe and it is now my FAVORITE favorite buttercream recipe.
Basically it was this:
4 sticks of unsalted butter, softened
8 cups of confectioner's sugar
6 tablespoons of heavy cream
4 teaspoons vanilla (I used clear for this recipe)
Blend the butter until smooth and add one cup of confectioner's sugar at a time. Add heavy cream and vanilla and blend until smooth.
Of course these "rose" cakes have been all over the baking blogs lately but I hadn't seen one quite like this. Most were one color and I thought it would look lovely to do a variation of the same shade. Yellow and chocolate seemed to be a good combination and I'm glad I chose it instead of something more predictable (ahem, pink). Only having one 1M tip made it a little difficult since I couldn't alternate the colors and had to do one at a time. I went back and filled in what I could with the tip and added a few more roses to hide some holes. This is my new favorite tip and I'm excited to use it next time I make cupcakes. Chocolate cupcakes with yellow roses would be lovely too!
