01 - Set the oven to 425°F and line a baking sheet with parchment paper.
02 - Drain and press tofu for at least 10 minutes to remove excess moisture, then cut into 1-inch cubes.
03 - In a bowl, toss tofu cubes with canola oil, cornstarch, salt, and black pepper until evenly coated.
04 - Arrange tofu cubes in a single layer on the prepared sheet and bake for 25–30 minutes, flipping halfway through, until golden and crispy.
05 - Whisk peanut butter, soy sauce, maple syrup, rice vinegar, sesame oil, garlic, and ginger together. Gradually add warm water until the sauce is smooth and pourable.
06 - Transfer baked tofu to a large bowl, pour peanut sauce over, and gently toss to coat evenly.
07 - Plate tofu immediately, topped with toasted sesame seeds, sliced spring onions, and fresh cilantro leaves if desired.
