Place 3/4 cup chocolate chips in a microwave-safe bowl. Microwave on high until just melted, about 1 minute. Stir and allow to cool slightly.

Combine tofu, peanut butter, and maple syrup in a blender. Add melted chocolate and blend until smooth.

Cover the bottom of the pie crust with banana slices and pour chocolate-tofu mixture over top. Sprinkle with remaining chocolate chips and chill until firm, about 2 hours.
