Into a small saucepan over medium-high heat, add the granulated sugar and water. Bring to a boil and cook until sugar is dissolved, stirring frequently. Set aside.
Using the microwave, heat chocolate in 20-second intervals until melted, stirring every 20 seconds.
Into a high-speed blender, add the sugar water, melted chocolate, silken tofu, ground cinnamon, vanilla extract, and chili powder. Blend on medium speed until the consistency is completely smooth, about 2-3 minutes.
Divide among serving dishes and chill for at least 30 minutes, until set.
