Preheat oven to 400°
I use a KitchenAid mixer to mix my dough.
In the mixer bowl cream together butter and sugar.
Then add in the eggs and vanilla.
Add the flour, baking powder, and salt, then mix on medium-low to incorporate it all.
Mix on medium until the dough forms a ball, and pulls away from the sides.
*Follow Instructions for each cookie variety you prefer Bake at 400° for 7 minutes. (7 minutes is the baking time for most all of the cookies except the cookies with the kisses, jam, and cinnamon they baked at 6 minutes as they are smaller.
**dough should be soft and not have a flour feel when fully mixed, it is easier to add a little flour. Once you add too much flour to cookies you can not remove it. So add a small amount (a tablespoon) at a time if you need it. You may not. You will be handling this dough quite a bit and don't want it to be dry after baking.
