Perhaps the most proper way to do it would be to take the whole callback outside of the setInterval call and put it in a separate variable:

(function () {
    window.Banner = {

        doMagic: function () {
            var magic = function() {
                console.log('magic');
            };
            setInterval(magic, 2500);
            magic();
        }
    }
})();

Banner.doMagic();

The effect is the same as your first code, but this way your code is a little cleaner.
