Per my own owners manual instructions which I got with my pasta machine..

The Correct Peanut Butter cookie recipe is:

2 1/2 Cup Flour
1 Teaspoon Baking Soda
1/2 Teaspoon Salt
1 Cup Sugar
1/2 Cup Brown Sugar
1 Cup peanut Butter
1/2 cup butter
2 Tablespoons Vanilla
2 Eggs
Sift flour, soda and salt into mixing bin. Add sugar. Mix dry ingredients for a minute in machine fitted with the large cookie die.
Stop machine. Open lid and add remaining ingredients (peanut butter, butter, eggs and vanilla). Close and MIX about one minute, then extrude.
If cookie dough stops coming out or slows down, it may be necessary to add more flour – 1 tablespoon at a time (through grate in the lid) to keep dough surface dry enough to drop down into extruder. Cook 375° for 10-12 minutes.

By the way, I'm looking for more cookie recipes for my machine if anyone has any... Thanks!!
