Combine milks and vanilla extract in a blender container.  Blend on medium speed for 7-10 seconds.

Slice Gansitos in thirds lengthwise.  Place 1 slice of Gansito in each mold, add milk mixture, cover and insert popsicle sticks.  Chill overnight or until firm.

Remove from mold by placing mold under warm water.  Remove cover and gently pull each stick to release.
