Update 6/10/14: One thing to note about the topping on this cake is that it is not like a traditional icing. It is meant to be more like cannoli filling. The texture is kind of like whipped cream at the soft peak stage. If you’d prefer it to be thicker, you can do one or both of these two things – leave the sweetened condensed milk out of the topping (as it thins it out a bit) and/or add up to about 3 cups of powdered sugar (which would thicken it). I chose to leave it thinner so that I didn’t dilute the cannoli flavor from the cheeses – I love that flavor! And though it’s thinner, it’s still plenty thick to be on top of the cake. I’ve made this cake a couple of times and it has sat out at parties and the icing stays in place. So it isn’t so thin that it runs or anything, it’s just not a traditional icing. I hope that helps, as I know many have been surprised the fact that it isn’t thicker.
