Preheat the oven to 350 degrees. Line a baking sheet with parchment paper. In a large bowl combine the white sugar, brown sugar, eggs, vanilla, butter, cinnamon, nutmeg, ginger and cloves. Mix until everything is evenly incorporated and it has a creamy texture (by hand or mixer).
In a smaller bowl combine the flour, salt and baking powder. Stir them until they are evenly combined. Add the flour mixture to the bowl of wet ingredients and stir it until a soft dough forms.
Using your hands (dust with flour if needed) shape the dough into two logs about 3 inches wide and 14 inches long. Bake in the oven for 35 minutes or until golden brown.
Remove the logs from the oven and carefully transfer to a cutting board. Using a serrated knife, gently slice the logs diagonally into 1 inch thick pieces (see photos below).
Place the slices back on the baking sheet. Sprinkle the tops with a mixture of cinnamon and sugar and bake for 5-7 minutes. Flip the pieces over, sprinkle the other side with cinnamon and sugar and bake for another 5-7 minutes. Let the biscotti cool on a wire rack before packaging or storing in an air tight container.
