Preparation Steps

• Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
• In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, and salt.
• Add the eggs and vanilla extract to the dry ingredients and mix until combined. Fold in the hazelnuts and chocolate chips.
• Divide the dough in half and shape each portion into a 12-inch log on the prepared baking sheet. Flatten each log slightly.
• Bake for 25 minutes, then remove from the oven and let cool for 10 minutes.
• Using a sharp knife, cut each log into 1/2-inch slices. Arrange slices cut side down on the baking sheet.
• Return to the oven and bake for an additional 15 minutes or until dry. Allow to cool completely.
