You can make these and set up the muffin tin and keep in the fridge for up to 4 hours before you bake it off. If you decide to bake these ahead of time, I’d bake these off and let them cool completely. You can then put them in freezer bags and store them in the freezer for up to two months. To serve, I just wrap one in paper towels and microwave for 30-40 seconds. Then I have an easy breakfast ready when I am. If you are doing more than one, you can also just put them on a baking sheet and reheat in a 350 degree oven for about 15 minutes.
