ANSWER: K-Cups are designed for one use only. You use the K-Cup once and then throw it away. If you find that wasteful, and a lot of Keurig brewer owners do, you can get a Keurig My K-Cup Reusable Coffee Filter .
Can I use Keurig Cups without machine hot chocolate?
Yes, you can use a Keurig cup without the machine. All you need to do is heat up water to either boiling or nearly boiling. Then pour the hot water into a mug with the Keurig cup powder in it, then mix it and add whatever afterward. I had to do this for about a week and a half cause we had no power.
