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.

You can mix the muffin up the night before

Oat flour is rolled Oats that have been blended in a food processor to resemble flour
You can use whole wheat or white flour either
