I've added some vanilla extract and substituted half of the white sugar for brown sugar, and it's amazing. I've made them four ways, one quarter without toppings, one with marshmallows, one with chunky peanut butter and one with chocolate coated coffee beans and all of them are so delicious! I don't know why I never get the light brown crust, it stays pretty dark for me, but that doesn't make them any less perfect!
