Ever wondered how Batman gets all those muscles to protect Gotham City? It’s through a process called injection molding. Plastic pellets are melted and injected into a Batman shape mold. Once the mold is full, the plastic cools down and hardens. Then, Batman is removed from the mold and ready to jump into action to fight crime! Try making a mold using chocolate! It’s fun and yummy!

chocolate molding


  • Baking tray or other flat plate
  • Parchment paper
  • Chocolate chips or melting candies
  • Microwaveable bowl
  • Cookie cutters for your chocolate mold shapes
  • Sprinkles, nuts, or seeds for extra yummy and crunch

Parental supervision required.


Cover the baking tray or plate in parchment paper and place the cookie cutters flat on the tray.


Place ½ cup chocolate chips in a microwave-safe bowl. Heat for 30–45 seconds and stir to avoid burning the chocolate. Repeat the heating process until the chocolate is melted and fluid.


Pour or spoon the melted chocolate into the cookie cutter mold. Make sure the entire bottom is covered.


Add sprinkles, nuts, or seeds.


Place the tray or plate in the freezer for 30–45 minutes. Once chocolate is hardened, remove tray from freezer and remove chocolate from cookie cutters.
