About these cookies
These biscotti taste like a mug of Mexican hot chocolate in cookie form: dark cocoa, plenty of cinnamon and a cayenne warmth that shows up a beat after the crunch. Pockets of dark chocolate stay melty in the dough, and the chocolate-dipped end softens nicely when you dunk it into something hot. They're sturdy enough to pack for a Día de los Muertos gathering and look great on a Halloween dessert table.

Tips for success
- Shape the logs with lightly oiled or damp hands. The dough is sticky on purpose, because cocoa dries out biscotti and a wetter dough slices more cleanly.
- Cocoa dough doesn't brown, so judge both bakes by touch: the logs should feel firm and spring back slightly after 25 to 30 minutes. For the second bake, give the slices about 15 minutes per side at 300°F (150°C), until both cut sides are dry and the centers feel nearly firm. Pulling them early leaves soft, cakey middles.
- Slice the logs after the 15-minute rest, while they're still warm. If they cool longer they turn brittle and crumble under the knife. Use a serrated knife and saw gently instead of pressing down.
- Chop the chocolate for the dough into small, pea-sized pieces. Big chunks catch on the knife and tear the slices.
- Cayenne heat builds as you eat. Taste a pinch of the dry mix before you combine it with the wet ingredients, and use 1/4 tsp cayenne if you're baking for kids or spice-shy guests.
Swaps
- No flaxseed: Use 5 tbsp aquafaba (the liquid from a can of chickpeas) in place of the flax egg and water. The biscotti will be slightly lighter and crisper but a bit more fragile when you slice them.
- Instead of neutral oil: Use 1/3 cup melted vegan butter for a richer, more buttery flavor. The crumb will be a little less crisp because vegan butter contains water.
- Instead of cayenne: Use 1 tsp ancho chile powder for a fruity, gentler warmth, or 1/2 tsp chipotle powder for a smoky kick.
- Gluten-free: Swap the all-purpose flour 1:1 for a gluten-free baking blend that contains xanthan gum. The logs will be more delicate, so let them rest the full 15 minutes before slicing.
Storing
Store the cooled biscotti in an airtight container at cool room temperature for up to 2 weeks, or freeze them between layers of parchment for up to 3 months and thaw at room temperature. If undipped biscotti soften, re-crisp them for 5 minutes at 300°F (150°C). Don't do this with the dipped ones, because the chocolate will melt.
