Steps
Before you start
- Preheat oven to 375°F (190°C)
- Line two baking sheets with parchment paper
- Have sourdough discard at room temperature (fed or unfed, both work)
Toast sesame seeds
- Spread white or mixed sesame seeds on a dry skillet over medium heat.
- Toast for 2–3 minutes, stirring frequently, until fragrant and lightly golden.
- Transfer to a plate to cool completely.
- Set aside 2 tablespoons for garnish if desired.

Ready when: Seeds are lightly golden and fragrant
Tip: Toasting develops a deeper, nuttier flavor and prevents the crackers from tasting raw.
Blend dough ingredients
- In a medium bowl, combine sourdough discard (1 cup / 240 ml), mole negro paste (3 tablespoons / 45 g), chopped dark chocolate (1 oz / 28 g), cinnamon (¼ teaspoon), and sea salt (¼ teaspoon).
- Stir vigorously with a wooden spoon until smooth and well combined, about 1–2 minutes.
- The mixture should look like thick batter with no visible lumps of mole paste.

Ready when: Mixture is smooth and uniform in color (darkish brown with spice notes)
Tip: If mole paste is very thick or clumpy, warm it slightly in a microwave (10 seconds) to soften before stirring into the sourdough.
Fold in toasted sesame
- Add the cooled toasted sesame seeds to the mole-sourdough mixture, reserving 2 tablespoons of sesame for topping if you wish.
- Fold gently with the wooden spoon until the sesame is evenly distributed, about 30 seconds.

Ready when: Sesame seeds are scattered throughout the dough without clumps
Tip: Don't overmix or you may bruise the sesame seeds and release excess oil.
Add oil and adjust consistency
- Drizzle olive oil (1 tablespoon / 15 ml) over the mixture and stir until fully incorporated.
- The dough should be thick enough to spread with a spatula—thinner than cookie dough but thicker than pancake batter.
- If it feels too thick, add water 1 teaspoon at a time.

Ready when: Oil is fully blended; mixture spreads easily but holds its shape
Tip: The sourdough discard's hydration varies; trust your eyes over the recipe if the batter needs adjustment.
Spread on baking sheet
- Divide the mixture between the two prepared parchment-lined baking sheets (about ¾ cup / 180 ml per sheet).
- Using an offset spatula or the back of a butter knife, spread in an even layer as thin as you can manage—aim for about ⅛ inch (3 mm) thick.
- You want thin, crispy crackers, not chewy ones.
- It's okay if the coverage is not perfectly uniform; thin spots will be extra crunchy.

Ready when: Layer is thin, roughly even, and covers most of the parchment
Tip: Work quickly but gently; if the dough is hard to spread, let it rest 2 minutes to relax. Thinner spreads yield crispier crackers.
Sprinkle optional garnish
- If using black sesame seeds, sprinkle the reserved 2 tablespoons evenly over both sheets for a striking visual contrast and extra sesame flavor.

Ready when: Black sesame scattered evenly across the dough
Tip: Black sesame seeds are optional but add visual drama and a slightly earthier sesame note.
Bake until crispyOven 375°F / 190°C
- Place both sheets in the preheated 375°F (190°C) oven.
- Bake for 22–26 minutes, rotating the sheets halfway through (around 12 minutes) for even browning.
- The crackers are done when the edges are dark brown and brittle, the surface is dry to the touch, and a thin piece lifted from a corner breaks cleanly.

Ready when: Edges are dark brown, surface is completely dry, and crackers snap cleanly when bent
Tip: If one sheet browns faster, pull it out 1–2 minutes early. Slight color variation is normal and adds to their rustic appeal.
Cool on sheet
- Let the crackers rest on the hot baking sheets for 5 minutes to firm up completely and become crisp as they cool.
- Then carefully break or cut them into irregular shards or 2-inch (5 cm) squares.
- Transfer to a wire rack for 5 more minutes to cool completely.

Ready when: Crackers are fully cool, completely brittle, and break cleanly
Tip: Breaking them while still slightly warm is easier than once they're stone-cold. Handle gently to avoid excessive crumbs.
Good to know
Tips
- Sourdough discard—fed or unfed—works equally well here. The tangy sourness complements the rich, bitter-sweet mole beautifully.
- These crackers are best enjoyed fresh and crispy. Serve them as a snack with cheese, spread with avocado or cream cheese, or alongside a cup of Mexican hot chocolate.
- The mole negro paste varies by brand; taste a small dab first if you're unfamiliar with it. Some are quite spicy; adjust the amount if needed.
- If your dough spreads unevenly, don't worry—the thin spots become extra-crispy flavor bombs, and thick spots remain chewier. Embrace the rustic look.
Storage & reheating
Store in an airtight container or jar at room temperature for up to 5 days. If they soften due to humidity, recrisp in a 300°F (150°C) oven for 3–5 minutes, then cool completely before serving. Not recommended for freezing, as the texture becomes damp upon thaw.
Substitutions
- Mexican mole negro paste → mole rojo paste. A milder, tomato-based mole will shift the flavor toward sweeter and less earthily complex, but still delicious. Reduce to 2 tablespoons if using a thinner paste.
- dark chocolate (70% cacao) → unsweetened cocoa powder (1 teaspoon / 3 g). Offers less richness and body, but if you don't have dark chocolate, cocoa powder works. Sift it in to avoid lumps.
- sesame seeds (white or mixed) → pumpkin seeds (pepitas), toasted. Provides an earthier, squash-like flavor and a different texture; maintains the nutty, toasted character.
- Mexican mole negro paste → homemade mole negro spice blend (1 tablespoon / 10 g chiles, cumin, cloves, cinnamon, cocoa). If you can't find mole paste, bloom whole spices in a bit of warm broth or oil first to awaken flavors, then add to the sourdough.
