Ingredients

• 2 cups all-purpose flour
• 1.5 teaspoons ground cinnamon
• 1 teaspoon baking powder
• 0.25 teaspoons salt
• 0.67 cups white sugar
• 6 tablespoons butter
• 1 large egg
• 1 large egg yolk
• 1 teaspoon vanilla extract
• 1 large egg , beaten
• 3 tablespoons white sugar
• 1 teaspoon ground cinnamon

Instructions

1. 1 Preheat the oven to 325 degrees F (165 degrees C). Line a baking sheet with parchment paper.
2. 2 Sift together flour, 1 1/2 teaspoons cinnamon, baking powder, and salt; set aside.
3. 3 In a medium bowl, cream together 2/3 cup sugar and butter. Beat in egg, egg yolk, and vanilla. Stir in flour mixture.
4. 4 On a lightly floured surface, divide dough in half. Roll each piece into a log about 9-inches long and 1 1/2-inches wide. Place logs on the prepared baking sheet and flatten slightly. Brush with beaten egg.
5. 5 Bake in the preheated oven until golden and firm to the touch, 25 to 30 minutes. Cool for 15 minutes.
6. 6 On a cutting board, slice each log crosswise at a diagonal into 1/2-inch-thick slices using a serrated knife. Place cut-side down onto the baking sheet. Combine 3 tablespoons sugar and 1 teaspoon cinnamon in a small bowl; sprinkle over biscotti.
7. 7 Return to the oven until toasted, 15 to 20 more minutes. Cool on wire racks and store in an airtight container.
