Step 1

Place enough water in the bottom of a 4-quart saucepan to come 1 inch up the sides. Bring to a simmer over medium heat.

Step 2

Melt the chocolate chips with the coffee liqueur and vanilla in a medium metal bowl set over the simmering water, stirring often with a rubber or silicone spatula. Although vanilla extract is often added at the very end of cooking, the melting chocolate will never get hot enough to damage the delicate sensibilities.

Step 3

Combine the chocolate mixture, tofu, and honey in a blender or food processor and spin until smooth, about 1 minute.

Step 4

Pour the filling into the crust and refrigerate until the filling sets firm, approximately 2 hours.
