How to Make It

Step 1

Preheat oven to 300°.

Step 2

Place liqueur in a small bowl. Microwave at HIGH 10 seconds. Stir in cocoa and espresso until smooth. Add oil, egg whites, and egg, stirring with a whisk until blended.

Step 3

Lightly spoon flours into dry measuring cups; level with a knife. Place flours, sugars, 2 tablespoons hazelnuts, baking soda, and salt in a food processor; process until hazelnuts are ground. 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. 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. Place rolls 3 inches apart on a large baking sheet coated with cooking spray. Bake at 300° for 28 minutes. Remove rolls from baking sheet; cool 10 minutes on a wire rack.

Step 4

Cut each roll diagonally into 20 (1/2-inch) slices. Place slices, cut sides down, on baking sheets. 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). Remove from baking sheets; cool completely on wire racks.

Step 5

Note: To toast hazelnuts, place on a baking sheet and bake at 350º for 15 minutes, stirring once. Turn nuts out onto a towel. Roll up towel and rub off skins. Chop nuts.
