Pre-Heat Solar OvenSet out your solar oven with the lid on in a sunny spot in order to preheat it a bit. Fifteen to thirty minutes is enough time to pre-heat on a sunny day.

Assemble S'Mores

Butter a large casserole dish. Remember to pick a dish that will lay flat in your solar oven.

Cover the bottom of the dish in graham cracker squares.

Break the chocolate bars into bite size pieces and put one or two on top of each cracker.

Place one to two marshmallows on top of the chocolate – however many it takes to fill the area of the graham cracker.

Reserve the top cracker until just before serving.

Baking S'mores in the Solar Oven

Once your dish is full, you're ready to put it in the solar oven.

Take the dish out to the solar oven and put it inside - remember the oven is pre-heated, so it will be hot.

Secure the lid and leave it in the sun to melt both the chocolate and the marshmallows.

Start checking your s'mores at twenty minutes for done-ness.

Use a spatula to serve up individual baked s’mores and place the finishing graham cracker like a hat on top of your s'mores.
