Instructions: Preheat oven to 350 degrees. Grease a cookie sheet or line sheet with parchment paper.

In a medium bowl, cream together butter and sugar. Add eggs and vanilla; mix until smooth.

Sift together flour, cinnamon, baking powder and salt; stir into the egg mixture. Stir in the hazelnuts.

Shape dough into two equal logs approximately 12 inches long. Place logs on baking sheet and flatten to about 1/2 inch thickness.

Bake in the preheated oven for 20-25 minutes. Let them cool slightly.

With a serrated knife, slice the logs diagonally into 1/2 inch wide slices.

Lay the slices on their side on the cookie sheet. Return to the oven for another 10 minutes, or until hard and crunchy. These are great dipped in white or dark chocolate.
