Preheat the Oven: Set the oven to 350°F (175°C) and line baking sheets with parchment paper.
Mix Dry Ingredients: In a bowl, combine flour, sugar, baking powder, and salt. Stir to blend evenly.
Prepare Wet Ingredients: Whisk eggs, vanilla, and almond extracts in another bowl until combined.
Form the Dough: Gradually add wet ingredients to the dry mix. Fold in chopped almonds until a sticky dough forms.
Shape the Biscotti: Divide dough into two logs, each about 10 inches long. Place them on the baking sheet.
First Bake: Bake for 25 minutes until firm. Let the logs cool for 10 minutes.
Slice the Biscotti: Use a serrated knife to cut ½-inch thick slices. Arrange slices cut-side down on the baking sheet.
Second Bake: Bake for 10 minutes per side until golden brown. Cool completely on a rack.
Make the Ganache: Heat cream and espresso in a saucepan until it simmers.
Melt the Chocolate: Pour the hot cream over chocolate chips and whisk until smooth.
Drizzle Time: Drizzle ganache over cooled biscotti for an elegant finish.
Set and Serve: Allow ganache to set before serving or dive in for gooey, chocolatey bliss.
