Step-daughter's birthday is coming up, and I want to make her
this cake. However, she is allergic to milk. According to her mom, she is "not just allergic to dairy products and lactose, she is allergic to the milk proteins."
Because of some messy, messy divorce issues (see past posts), her mom won't give us a detailed list of what she can and can't eat, but we do know that she can have baked goods, like cake and cookies, and things with some butter in them (e.g. mashed potatoes), because her mom often sends those along as snacks.
So, to be safe, what kind of frosting can I put on this cake that will be fun and edible? Normally we substitute things like peanut butter, but that would be disgusting on a cake. I'm willing to make some sort of icing, but I want to err on the side of caution, and not make anything that includes an overload of butter.
1/2 cup non-hydrogenated shortening, such as spectrum
1/2 cup non-hydrogenated margarine, such as earth balance
3 1/2 cups powdered sugar, sifted if clumpy
1 1/2 tsp vanilla extract
1/4 cup plain soy milk or soy creamer
