Preheat the Oven:

Begin by preheating your oven to 350°F (175°C) and lining a baking sheet with parchment paper.

Mix Dry Ingredients:

In the bowl of a stand mixer, combine the flour, baking powder, salt, and sugar.

Add Eggs and Flavor:

Beat in the eggs, egg yolks, and almond extract into the flour mixture. Continue to mix until a sticky dough forms.

Knead in Cherries and Almonds:

Lightly flour a clean surface and turn out the dough onto it. Gently knead in the chopped candied cherries and sliced almonds until they are evenly distributed throughout the dough.

Shape and Bake:

Shape the dough into a log and place it onto the prepared baking sheet. Bake in the preheated oven for 25 minutes.

Cool and Slice:

After the initial baking, remove the log from the oven and allow it to cool. Once cooled, reduce the oven temperature to 250°F (120°C). Slice the log into individual biscotti.

Bake Again:

Place the sliced biscotti, cut side up, onto the baking sheet and bake for an additional 20 minutes. Then, flip them over and bake for another 20 minutes.

Cool and Serve:

Remove the biscotti from the oven and allow them to cool completely before serving. They will continue to crisp up as they cool.
