Wrap the tofu in a paper towel to remove excess moisture.
Mix the tofu with almond flour, unsweetened cocoa powder, erythritol, and baking powder in a bowl until well combined.
Spread the batter evenly in an oven-safe container.
Bake in a preheated oven at 180°C (356°F) for 20 minutes.
Let cool and cut into bite-sized pieces.
