Preheat oven to 325°F (165°C). Line a baking sheet with parchment paper.
In a large bowl, whisk eggs, melted butter, vanilla extract, and almond extract until combined.
Add almond flour, sugar, baking powder, and salt, and mix until a dough forms.
Fold in sliced almonds and chocolate chips.
Divide dough in half. Shape each half into a log about 8 inches long and 2 inches wide on the prepared baking sheet, spacing them 2 inches apart.
Bake for 25–30 minutes, until logs are firm and lightly golden.
Remove from oven and let cool for 10 minutes. Reduce oven temperature to 300°F (150°C).
Using a serrated knife, slice each log diagonally into ½-inch thick slices.
Place slices cut-side down on the baking sheet. Bake for 10 minutes, flip, and bake for another 10 minutes until crisp and dry.
Cool completely on a wire rack. Biscotti will continue to harden as they cool.
