The only thing I do with Chocolate chip cookies to keep them soft is not bake them to long. Take them out as soon as they are browning around the edges. They can be light brown in the middle too. But like someone said they will bake a little as they cool in the pan before transfering them to a cooling rack.
So if it says 10 mins. leave in for 8. The first batch might take the whole ten but after that do 9.
I use margrine right out of the fridge, that doesn't seem to effect it any for me at least.
And the only time I use extra flour is if the cookies spread out , this will happen when you use different margrines.
Here is my reciepe:
1 cup flour
1/2 tsp. salt
1/2tsp. baking soda ( mine is in the cupboard forever...haha)
Mix together
In another bowl
1/2 cup butter or margrine
2/3 cup brown sugar
cream
add 1 egg
1/2 tsp. vanilla
add to butter mixture then add the flour mixture to that .
Add 1/2 chocolate chips
optional add cup of walnuts ( we dont' like nuts)
bake at 375 for 8-10 mins. I bake at 8 for soft cookies.
I make this cookie a lot for every member in my family... because they are soft.
