Sugar Free Cream Cheese Icing
3 blocks of 1/3 less fat cream cheese (aka Neufchatel Cheese), softened
1 pkt sugar free vanilla instant pudding
2% milk (or FF 1/2 n' 1/2)
nutmeg to taste
Whip the cream cheese and SF vanilla pudding mix together. Add enough 2% milk to make it fluffy, then add nutmeg to taste. This makes a thick icing, heavy enough to pipe borders around a cake, but not thick enough to create icing flowers. To make it runnier, you can try using more milk or cut it in 1/2 and add extra milk.
I believe this should frost one sheet cake, but the original recipe didn't say. Sorry about that! I've used a recipe like this, which only used 2 blocks of cream cheese, to frost about 3 dozen cookies with frosting/icing left over.
