We made cookies that we glazed with a simple sugar icing. The icing is simple
- confectioners sugar
- skim milk
- almond extract
At first the icing was normal and hardened when dry on the cookie surface, but after a few days, it started to get really wet looking and lost its glazed appearance, like it was melting. It looked really bad after.
The base of the cookie dough consists of
- approx. 8 - 10 cups cake and pastry flour (extra as needed)
- approx. 3/4 cup sunflower oil
- 12 egg yolks
- 2 cups of milk
- backing powder
I'm just wondering what would cause this? Is it an interaction with the cookie or the ingredients of the icing or both?
