Bake cupcakes according to package directions and cool completely.
Frost each cupcake with green frosting and let set for 10 minutes.
Create "apples" by adding a tiny dab of green frosting on red Skittles or M&M's for leaves.
Pipe "ABC" or "A+" on chocolate graham crackers with white writing icing, leaving blank space at bottom.
Cut a small groove in each cupcake's frosting to create a slot for standing the graham cracker.
Insert graham cracker "chalkboard" and add your apple candy and white Good & Plenty "chalk" piece.
