Remove the silken tofu from the fridge 1 hour before preparing. It is important for the tofu to be at room temperature. If it is too cold, the chocolate can start to solidify in the blender, and you will lose the smooth texture.
In a heat safe bowl, melt the chocolate in the microwave in 30 second intervals, stirring between each round, until fully melted.
Add the tofu and melted chocolate to a blender and blend until completely smooth. I usually process for about 2 minutes, giving the blender short breaks if needed.Pour the mixture into jars and refrigerate overnight to set.
