Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper.
Cut the tofu into two flat slabs and gently press out excess moisture with paper towels for 5–10 minutes.
Cube the tofu and transfer it to a large bowl.
Add the cornstarch, soy sauce, olive oil, and salt. Toss gently until evenly coated.
Spread the tofu cubes onto the prepared baking sheet in a single layer.
Bake for 20–25 minutes, turning once or twice until golden brown and crispy.
Meanwhile, cook the rice according to the package directions.
In a small bowl, stir together the Yum Yum sauce, chili crisp, and honey if using.
Toss the baked Chili Crunch Tofu with several spoonfuls of the sauce.
Serve over rice, drizzle with additional sauce, and garnish with green onions.
