Step 1

Cream butter and sugar until very fluffy.

Step 2

Add eggs and vanilla and mix until incorporated.

Step 3

Add dry ingredients and beat on high speed in mixer for 12 - 14 minutes. Scrape bowl often.

Step 4

Scoop out cookies (a little smaller than a ping pong ball) and place on cookie sheet that is either Teflon coated or lined with parchment paper. Parchment (silicone) paper is your best choice. Do not grease pan.

Step 5

Flatten cookies with finger tips that are slightly moistened. The moisture will prevent your fingers from sticking to dough as you flatten the cookie dough.

Step 6

Bake at about 350 F for 6 minutes. Rotate pan (front to back) to distribute heat and then bake a further 6 minutes. Remove from oven and leave on pan until stiff enough to handle. They will be very soft when they first come out of the oven.

Step 7

You may need to alter the baking time and temperature of your oven if you do not get a satisfactory result. No two ovens bake the same, even if you have clones.
