Blend the mixture

• Place the beans, olive oil, salt, garlic powder and onion powder 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 and evenly as possible with a spatula.

Bake

• Bake at 175 °C for 25–30 minutes, checking often since time depends on thickness.
• Remove from the oven and score cracker shapes with a knife or pizza cutter.
• Flip the pieces if possible and return to the oven to finish drying.
