Mix everything except the chocolate in a large bowl. In a double boiler, melt the chocolate. Use low heat, it burns and separates very easily! When the chocolate is mostly melted, pour it onto the dry mix in the bowl. You will need to mix it with your hands, so wear disposable gloves since the chocolate is hot. And be careful to not break up all the pretzels. Once everything is coated in chocolate spread it out on wax paper in about 1 inch thick layers. It will use up all your counter space! Let it dry at least several hours, or overnight if possible. Once dry, you can break it into small chunks and store it.
