Preheat the oven to 200°C (180°C fan) or preheat your air fryer to 190°C.
Line a baking tray with baking paper if using the oven.
Slice each aubergine into rounds approximately 1–1.5 cm thick.
Place the crushed cornflakes into a shallow bowl.
In a separate bowl, whisk together the plant milk and cornflour until completely smooth.
Dip each aubergine slice into the plant milk mixture before pressing firmly into the crushed cornflakes until evenly coated.
Arrange on the prepared baking tray.
Lightly brush both sides of each coated aubergine slice with olive oil.
Bake for 30–35 minutes, turning halfway through, until golden brown and crispy.
Alternatively, air fry for 15–18 minutes, turning halfway through cooking.
Meanwhile, prepare the tofu aioli.
Add the silken tofu, olive oil, lemon juice, nutritional yeast, garlic and salt to a blender or food processor.
Blend until completely smooth and creamy.
Taste and adjust the seasoning if needed.
Serve the crispy aubergines immediately with the creamy tofu aioli for dipping.
