Preheat the Oven: Preheat the oven to 180°C (350°F) and line a baking tray with parchment paper.
Mix Dry Ingredients: Combine flour, sugar, and baking powder in a large bowl.
Add Wet Ingredients: Beat the eggs and mix them into the dry ingredients until a firm dough forms.
Add Flavorings: Fold in whole almonds or your preferred additions, such as chocolate chips or pistachios.
Shape the Dough: Divide the dough into two portions and shape each into a long, flat log on the prepared tray.
First Bake: Bake for 25–30 minutes until the logs are lightly golden and firm. Remove them from the oven and cool for 10–15 minutes.
Slice the Logs: Using a serrated knife, cut the logs diagonally into slices approximately 1–2 cm thick.
Second Bake: Arrange the slices flat on the tray and bake for another 10–15 minutes, turning halfway through, until crisp and dry.
Cool and Serve: Allow the Biscotti to cool completely before serving with coffee, tea, or hot chocolate.
