Directions

1. Preheat oven to 30
2. Place liqueur in a small bowl. Microwave at HIGH 10 seconds. Stir in cocoa and espresso until smooth.
3. Add oil, egg whites, and egg, stirring with a whisk until blended.
4. Lightly spoon flours into dry measuring cups; level with a knife.
5. Place flours, sugars, 2 tablespoons hazelnuts, baking soda, and salt in a food processor; process until hazelnuts are ground.
6. Add ground coffee; pulse 2 times or until blended. With processor on, slowly add liqueur mixture through food chute; process until dough forms a ball.
7. Add 6 tablespoons hazelnuts; pulse 5 times or until blended (dough will be sticky). Turn dough out onto a floured surface; knead lightly 4 to 5 times. Divide dough into 3 equal portions, shaping each portion into a 10-inch-long roll.

13. Bake at 300 for 20 minutes. Turn cookies over; bake an additional 10 minutes (cookies will be slightly soft in center but will harden as they cool).
14. Remove from baking sheets; cool completely on wire racks.
15. Note: To toast hazelnuts, place on a baking sheet and bake at 350 for 15 minutes, stirring once. Turn nuts out onto a towel.
