This is my standby creamcheese icing recipe. It's from Canadian Living magazine. I love the calculator for multiplying the recipe according to how many cupcakes you've got.
This is for 12 cupcakes. I had extra leftover; I only needed 3/4 of the recipe. I suppose it all depends on how much you love icing!
1/4cup (50 mL) cream cheese, softened
1/4cup (50 mL) butter, softened
1/2 tsp (2 mL) vanilla
1-1/2cups (375 mL) icing sugar
Mix all ingredients together in a bowl. Transfer to piping tube. Ice those cupcakes!
