Process
the tofu and maple syrup in a food processor until smooth and
creamy, about 2 minutes. Transfer to a small, heavy saucepan. Add
the chocolate chips and stir to combine.
Warm over
very low heat, stirring constantly while scraping the sides and
bottom of the pan, until the chips have melted completely. Stir well
to thoroughly blend in the chocolate. Remove from the heat and stir
in the vanilla.
Transfer
to a covered container and refrigerate several hours until well
chilled. Stir again before using.
