Step 1
INSTRUCTIONS
Add vanilla to beaten eggs. Turn off mixer. Just combine flour. Create dough logs from each half. Plastic-wrap each dough log and chill for an hour or week.
Step 2
Sprinkle cold dough logs. Pre-heat the oven to 350ºF and line two baking pans with parchment paper. Cut 1/4-inch log circles. Bake cookies 1" apart on pans. Freeze cookies 10 minutes.
Step 3
Bake cookies 12–15 minutes to set. After 5 minutes on the baking sheet, cool biscuits on a wire rack. Slice and bake the second dough log.
