  2. If you don’t want to cook them off straight away, then place them in the refrigerator for up to 24 hours.

Recipe Notes

Cooking time will vary greatly depending on your microwave and the width and depth of the mug. The mugs I use are small, roughly 6oz (¾ /1 cup)

Always keep a close eye on your mug while in the microwave so it doesn’t over flow or over cook
