My mother-in-law gave me a book a few years ago that has recipes that you can make with your kids. It is a really cute little book. The book is called "Alphabet Snacks" by Elizabeth McKinnon, illustrated by Gary Mohrman, and published by Totline Publications. I don't know where she got it from and I have had a hard time trying to find it online which is too bad, because it is a really great children's cook book.
Try this recipe when the weather is in the mid-80's or above. In a glas baking dish with a lid arrange graham cracker squares in one layer. Use scissors dipped in water to cut marshmallows in half horizontally. Place one marshmallow half, cut side up, on each graham cracker square and top with chocolate chips. Put the lid on the baking dish and place the dish outdoors in direct sunlight. Check periodically. When marshmallows and chocolate chips are melted eat and enjoy. Each Sunshine S'more makes 1 serving.
Variation: For year-round S'mores, top graham cracker squares with chocolate chips and miniature marshmallows. Heat on low in the microwave for a few seconds, just until marshmallows and chocolate have melted. Let cool slightly before serving.
