Begin by washing the green apples thoroughly under running water. Next, use a sharp knife to quarter each apple and carefully remove the core; create a V-shape at the center for the monster mouth.

Spread a generous layer of creamy peanut butter inside each apple mouth to serve as a tasty adhesive for the monster's teeth.

Press a few pumpkin or sunflower seeds along the inner edge of the peanut butter-filled mouth to mimic monster teeth.

Cut slices of cheddar or Colby Jack cheese into triangles and gently insert them into the apple mouth for a toothy grin.

Using the remaining peanut butter as glue, stick a few candy eyes on top of the apple slices to bring your Green Apple Monsters to life.

Serve these delightful creations immediately for the best texture and taste. Store in an airtight container in the refrigerator for up to three days.
