Prep: Preheat the oven to 350°F. Line a baking sheet with parchment paper.
Make the dough: Mix the butter, sugar and extract with a sturdy wooden spoon or spatula until no lumps remain.
113 grams unsalted butter, 170 grams cane sugar, 2 teaspoon vanilla extract, ¼ teaspoon almond extract
Stir in the wet ingredients and until fully combined.
56 grams sourdough discard, 1 egg
Fold the dry ingredients in, bring the dough together into a ball with your hands.
240 grams all-purpose flour, 40 grams cocoa powder, 7 grams baking powder, ½ teaspoon sea salt, 1 teaspoon espresso powder
Shape the dough: Using your hands form a large log out of the cookie dough and flatten slightly so it’s about 1-inch thick, it should be about 12 by 3 inches. Sprinkle cane sugar on top and top with chopped almonds, if using.
20 grams cane sugar, 40 grams almonds
Bake: Bake for 40 minutes or until the middle looks set, and the log looks lightly browned.
Remove from oven and let rest for 10 minutes.
Trim off the edges, then slice into 14 pieces and arrange them in a single layer on a parchment-lined baking sheet.
Arrange the biscotti into an upright position to ensure even baking, eliminate the necessity to flip them halfway through the process.
Reduce the oven temperature to 300 F and bake for another 30 minutes or until they look dried out.
Enjoy and store: These are best enjoyed once they have fully cooled and the chocolate has set. Store leftover in an airtight container in a cool, dry place for up to 7 days.
