I want to second the recommendation of chilling the dough first! I make CC cookies several times a week and it's SO easy!
Melt 1 stick of butter
Whisk in 1 cup brown sugar and 1/2 cup white sugar and 1 egg
Whisk till well combined
Sprinkle 1 tsp salt into mixture
Now add a 'splash' of vanilla (2 tsp? 1? doesn't matter?)
a TINY pinch of cinnamon (maybe 1/8th tsp?)-it shouldn't be noticeable, but it adds a happy boost
Add 1 and 1/2 tsp Baking Soda to mix
Add 1/8th tsp Baking Powder to mix
Stir all above together well to combine.
Add in 2 cups 'fluffed' or sifted flour and mix well.
Add 1 cup choco chips and 1 cup chopped walnuts (all together now...yummmmmm!)
Add 1/2 cup sifted/fluffed flour. Mix well again.
Refrigerate for about an hour, until dough is well chilled.
If you want to REALLY make life easier on yourself, make this a double batch and plop the whole thing onto wax paper. Then shmooze it into a log and wrap it up. When it's chilled you have your own personal easy bake cookie log! Just slice and bake!
Oh and I bake at 360 for 8-12 minutes, depending on how many cookies I'm doing.
