What is a non alcoholic sub for brandy in cookies?

Usually !/3 cup fluid in cookies means that it is integral to the recipe (unlike 1/3 cup fluid in soup). Changing brandy with non-alcoholic sub could be tricky because it could effect the texture (due to alcohol) a lot. Also a lot of alcohol content are baked off during baking so that might not even be an issue. What is the recipe?

Adding a different flavor would depend on the type of cookie.
What is the main flavor of the cookie?

Fruit syrup (diluted if it's too thick).
Good quality grape or other fruit juice.
