Although the secret to the recipe for Milles Cookies is a company secret (the cookies are delivered in-store in frozen batches), it appears that the secret to a chewy-cookie is to use both brown and caster sugar in your recipe. A recipe using oil or melted butter will also make chewy cookies.
There is a large volume of water in margarine. This will make the cookies or anything drier and most likely crumbly. You can use oil in place of margarine in most things, but not the reverse.
Yep, but shortening or lard will work better, if using oil reduce other liquids by about 1/2 the oil used. Results will be different than if using a "short" fat.
Substitute margarine for butter and applesauce for oil.
Yes, but depending on the amount of oil involved, it might make the cookies taste a little but 'different'.... mot bad, but different. If there is to be any flavouring used, add a bit extra to mask the olive oil.
For most cookies you can't use oil in place of shortening.
When in doubt, make cookies.
YEP! It is not only the sweetening of sugar that is needed for baking, but the granular consistency. You CAN the make cookies, but they will no doubt not be as well formed as those made with granulated sugar.
You can spread it on bread, use it is drinks in place of sugar, and make cookies and candy using it.
your cookies will be ok
The advantage of using oil is to make things work. (For example you take advantage of oil by using it in transportation.)
