In a large pot, combine the apple juice and cranberry juice.
Stirring occasionally, bring to a boil and then remove from heat.
Add the schnapps to the warm juice and serve in mugs.
If you use a slow cooker for your party, heat the juices on high heat and then reduce to low when adding the schnapps. Substitute spiced rum or brandy for the schnapps. Garnish the mugs with cinnamon sticks, orange slices, or cranberries.
