Glaze for Bundt Cake

[mumu]

I made a glaze for my bundt cake.... Powder sugar, milk and vanilla and butter. Most glazes I make don't use butter. The question I have Is the glaze isn't getting hard like it sholuld could it be bec. Of the butter?

I forgot to add it also has cream cheese in it. Would the butter and cream cheese prevent it from hardening up?

Milk makes a soft glaze. Water makes a hard glaze.

I did make it with water this time .....usually I do use milk. But even with the water it still was not hard. Does butter or cream cheese have any thing to do with it hardening up?
