I found this cookie icing recipe at allrecipes.com. It's really good /once you alter the proportions/ of the liquid & corn syrup. It produces a creamy and glossy icing that dries out beautifully.
Ingredients
- 1 cup powdered sugar, packed
- 1 1/2 Tbsp. milk
- 1 1/2 Tbsp. corn syrup
- 1tsp. vanilla extract
- food coloring
Mix the sugar and milk in a small bowl until smooth. Beat in the corn syrup and vanilla extract, until smooth and glossy. If the icing is too thick, add more corn syrup.
Divide the icing into small different bowls. Add a few food coloring drops and mix well. Bush on top of sugar cookies. Let rest for 15 minutes to harden.
