Blend the mixture

• Place the beans, olive oil, salt, garlic powder, onion powder and any optional flavorings in a food processor or blender.
• Blend until very smooth and thick, like a dense hummus.

Spread thinly

• Line a baking sheet with parchment paper.
• Spread the mixture as thinly as possible with a spatula; thin crackers turn out crunchy.

Bake and score

• Bake at 175 °C, checking often since time depends on thickness.
• Score cracker shapes with a knife or pizza cutter.
• Flip the pieces if possible for even crispness.
