1-2-3 Dough is on of the basic formulas that all bakers should know. 1-2-3 is a ratio for 1 part fat, 1 part sugar, and 1 part flour. You need to include the eggs and any flavoring, but that is a ratio that will create the same consistent product no matter how much you need, big or small.
8 ounces (2 sticks) butter
1 pound of sugar (2 1/4 Cups)
1.5 pounds of flour (4 1/4 Cups)
*if you have problems with your dough coming together, you can a small amount of water.
