Add chopped chocolate and coconut oil to a microwave-safe bowl and microwave in 30-second increments until smooth; set aside.
Place the tofu into your food processor and pulse until smooth. Then, add the cocoa powder, maple syrup, sugar, espresso powder, vanilla, and salt and pulse until everything is combined. Last, add the melted chocolate and pulse until the mixture is smooth and creamy, scraping down the sides as needed.
Scoop the mixture into 4 small ramekins or jars and place them in the refrigerator for at least 2 hours, which will allow the pudding-like consistency firm up and turn into mousse. Enjoy!
