Recipe is copied from recipezaar, I think someone mentioned pepper cookies during chat and I have googled them - and tried the recipe this week. Wow :)
2 1/4 cups all-purpose flour
1 cup granulated sugar
1 cup sweet unsalted butter, softened (don't fall into trap of using all 200 g box - too much)
1 large egg
1 teaspoon baking soda
1 teaspoon pure vanilla extract
1 1/2 teaspoons black pepper
extra sugar, for dipping glass
Directions
1. Mix all ingredients (except for the extra sugar for dipping the glass) together well using a heavy duty mixer.
2. Roll into 1/2 inch size balls-you will need three large ungreased cookie sheets, 16 balls per sheet.
3. Use the flat base of a drinking glass that has been dipped into sugar to flatten each dough ball on the cookie sheets.
4. Bake in a preheated 350 F (or 180 C) oven for 8-11 minutes or until lighly browned on the edges- do not overbake.
5. Remove to wire racks to cool.
With 1/2 inch balls I got much more cookies, close to 100; could be my half inch was metric

Egg was too small so I have added a bit of cream. No vanilla extract, but so called vanilla sugar did the trick.
