smores in a pizza box solar oven

No campfire? No problem! Try making s’mores using solar energy with this fun project from


  • pizza box
  • black construction paper
  • aluminum foil
  • plastic wrap


Cut the “oven door” flap on the box. Decorate with markers if you wish!

Glue black construction paper to the bottom of the box. The black color absorbs the heat.

Glue aluminum foil to the inside of the door. The foil reflects the sun into the oven.

Tape the plastic over the opening of the door. The plastic wrap allows the air inside the box to heat up but keep the heat trapped inside the box.

Add a graham cracker, marshmallow, and chocolate inside the oven.

Place your oven outside in the sun. Use a wooden skewer to keep the lid propped open if needed.

Watch as the chocolate melts and the marshmallow puffs up from the heat! It may take 1-2 hours to fully bake the s’mores. Pro tip: these are delicious even with just the chocolate melted! 🙂
