Common ingredients found in magic cookie bar recipes include graham cracker crumbs, butter, sweetened condensed milk, chocolate chips and flaked coconut. The original recipe also includes chopped nuts, such as pecans or walnuts. Recipe variations may add butterscotch morsels, peanut butter chips, white chocolate chips or dried fruit.
To make magic cookie bars, mix 1 1/2 cups graham cracker crumbs with 1/2 cup melted better. Press the mixture into the bottom of a baking dish. Pour one 14-ounce can of sweetened condensed milk over the graham cracker mixture, and layer the cookie bars with 1 cup chocolate chips, 1 cup chopped nuts and 1 1/3 cups flaked coconut.Once all of the ingredients are in the dish, press firmly on the top.
Bake the cookies for approximately 25 to 30 minutes at 350 degrees Fahrenheit, or until the top is lightly golden. Remove the cookies from the oven and run a knife around the inside edge of the dish to loosen the cookies from the sides of the pan. Allow the dish to cool on a wire rack, or chill it in the refrigerator before cutting it into bars.
To make a variation, add or swap ingredients. For example, the recipe from the food blog, Sally's Baking Addiction, calls for butterscotch morsels to be mixed in with the graham cracker crumbs and pre-baking the crust for five minutes before adding the other ingredients.
