Christina's Notes
Cool: While the recipe says to let the coffee cool for 30 minutes, I found it best to let it sit in the fridge overnight. I liked how the flavor intensified overnight.
Alcohol: I added chocolate liqueur and Rumchata to my punch, but you can easily substitute your favorite liqueur – Bailey’s irish cream would be good as would whiskey or dark rum or kahlua. Also, you can make an a liquer free version if you wish.
Flavored Coffee: If you want to make a flavored coffee punch, you can add a flavored coffee creamer in place of the milk. Just be sure to adjust the sugar so it’s not too sweet.
Strong Coffee: You can use instant coffee, espresso, brewed coffee instead or even a cold brew coffee concentrate from the store. Even use a coffee ice cream.
