I made this cake for a birthday party. It got a lot of laughs!
Here's how I did it:
I made a 10" two layer Chocolate Truffle cake with Chocolate Truffle filling and set it in a large shallow bowl. I spread more of the filling over the top of the cake just to make it even richer! I then covered the cake with Buttercream Frosting (I used butter to get the spaghetti color) using a #5 tip. It took 2 batches of icing, but I think my recipe makes a smaller amount than the Wilton recipe, so you might get by with one batch. I built it up a little bit in the center.
The spaghetti sauce is strawberry jam with a little yellow gel and white coloring. Just add a small amount of color, then mix together. You may have to add a little more color to get the affect you want and if you add too much, just add a little more jam. You really can't mess it up!
The meatballs are truffles, the ones with the crunchy stuff on the outside. After it was all put together, I grated a little white almond bark over the top.
