This is a good recipe for when you bring your Sun Oven on camping trips, picnics, or a day at the beach. Measure the ingredients beforehand than just combine them all in the baking pan.
One Pan Sun Baked Bar Cookies
1/2 cup unsalted butter or coconut oil
1 1/2 cups graham cracker crumbs
1 (14-ounce) can sweetened condensed milk
2 cups semi-sweet chocolate chips
1 1/3 cup flaked coconut
1 cup chopped nuts
Set Sun Oven out to preheat.
Put the butter or coconut oil in a rectangular baking pan and place it in the Sun Oven until melted, 5 to 10 minutes. Sprinkle the graham cracker crumbs over the melted butter or oil. Pour the condensed milk evenly over the crumbs. Scatter chocolate chips, flaked coconut, and chopped nuts over everything and press down firmly. Bake, uncovered, until lightly browned, about 45 minutes. Cool in the pan on a rack. Cut into bars or squares.
