Vanilla & Chocolate Striped Biscotti
Twice-baked Italian almond-studded biscotti with striking vanilla and chocolate layers, finished with contrasting chocolate drizzles. The method creates dramatic striped logs that are crispy and perfect for dunking in coffee or hot chocolate. Serve these elegant cookies at afternoon tea, holiday gatherings, or as gifts. This version uses the traditional two-bake technique to achieve the signature crunchy texture while the marbled appearance and dual-chocolate topping set it apart from simpler biscotti recipes.

Tips
Use a sharp serrated knife and a sawing motion when slicing biscotti to prevent crumbling. Chill the first-bake logs for 10 minutes before slicing for cleaner cuts.
Toast walnuts in a dry skillet over medium heat for 3-5 minutes before chopping to intensify their flavor and ensure even distribution throughout the dough.
Melt chocolate slowly over low heat and stir frequently to prevent seizing. Alternatively, use a double boiler for more controlled melting.
Good to Know
Store in an airtight container at room temperature for up to 2 weeks. Keep in a cool, dry place away from humidity to maintain crispness.
Biscotti can be made up to 1 week in advance and stored undrizzled. Drizzle with chocolate up to 3 days before serving. Freeze undrizzled biscotti for up to 3 months.
Serve with coffee, espresso, hot chocolate, or tea. Pair with dessert wine or after-dinner drinks. Ideal for gift-giving in decorative boxes.
Common Mistakes
Do not underbake the second time; ensure biscotti are fully golden and crisp to achieve proper dunking texture.
Do not cut logs while still warm; they will crumble. Cool completely first.
Do not skip the 15-minute cooling period after the first bake, as the logs need to set before slicing.

Full guide →FAQ
Can I freeze biscotti before or after dipping in chocolate?
Yes. Freeze undrizzled biscotti for up to 3 months in an airtight container. Drizzled biscotti can be frozen for up to 6 weeks but may have slightly less crisp chocolate coating. Thaw at room temperature for 1 hour before serving.
What if my chocolate seizes when melting?
Stop heating immediately and stir in 1 teaspoon of vegetable shortening or coconut oil to smooth it out. If that fails, start over with fresh chocolate. Avoid water and steam contact, which causes seizing.
How long does it take to make biscotti from start to finish?
Total time is approximately 1 hour 45 minutes including 20 minutes prep, 23-28 minutes for first bake, 15-minute cooling, 14-18 minutes second bake, cooling, and 10 minutes for chocolate work.
