I buy the Starbucks iced coffee in a bottle.

I just make regular coffee. Use a French vanilla creamer, and then chill it or blend it with I've into a frappe

I just make caramel coffee k cups, refrigerate, cream, sugar & ice 🤷🏽‍♀️

Just make a very very strong pot of coffee. Pour into a cup. Add ice and two tablespoons of flavored syrup -- you can get some flavored coffee syrups in the coffee aisle. Mix it together, add a splash of milk/whipped cream and done.
