Core apples to ½ inch of their bottoms. It helps if you have an apple corer. If not, simply use a paring knife. Cut out the stem area first, then the core. Use a spoon to dig out the seeds. Make the incisions about ¾-inch wide.
In a small bowl, mix apple juice concentrate and vanilla. Pour into cored center of each apple.
Place a cinnamon stick in the center of each apple. Place apples on nonstick baking sheet and bake in oven for 20 minutes.
Decorate with plastic spider and edible eye candies (but don't eat them!)
