Q&A for How to Make a Whipped Coffee

You may add vanilla extract.

Yes, you can. You can use milk or other types of creamer.

Yes, if you like the flavor of cream cheese. However, you will have to heat the coffee up enough to melt the cheese so that you can properly mix it in.

Yes. Use it in place of the hot water, but start with just one tablespoon, as the 1:1 mix of instant coffee and water is stickier and more syrupy than your brewed coffee will be.

It works best with instant coffee. If you use another kind, brew it as normal, and then use it in place of the hot water. For method 2 with cream and hot milk, use it in place of the hot milk and just whip the cream and sugar together.

No, but you do need to use some kind of granulated sweetener. The granules (of sugar or Swerve or whatever have you) are what make the foam by aerating the mixture - the instant coffee dissolves too quickly to create this effect.
