Shortcut with eggnog and pumpkin pie spice! I also like using leftover cinnamon rolls, cinnamon bread, or pannatone. Make it healthy with no sugar added bread, sugar-free hershey bars, splenda, soy or low-fat eggnog and fat free half-n-half. I also like using white chocolate chips or a white/brown combo. For a more unique flavor, use cloves, nutmeg, cinnamon (i use 1 TBS each because i like the spice) and add some rum extract. Add some nuts on top if you'd like.
