IS BAKING WITH OAT FLOUR GOOD FOR CLEAN EATING?
Baking with oat flour is a great idea if you're trying to eat a clean eating diet. Oat flour produces a soft and tender crumb to most baked goods and tastes delicious. You'll have a mild, slightly nutty flavor to your baked good and notice a delicious depth of flavor to all your homemade treats.
Plus, you're getting all the heart-healthy benefits of oats baked right into your delicious baked goodies. Anytime I can make heart-smart decisions and enjoy a yummy bakery-style treat is a win-win to me! If you're interested in learning more about the healthy benefits of oatmeal, here's a good article from The Mayo Clinic.
And, since oats are naturally gluten-free, this is the perfect mug cake for anyone who not only wants to eat healthier but needs a gluten-free dessert too!

EXPERT TIPS
MICROWAVE COOKING TIME
Microwaves may vary in their cooking time based on the power they output. Here are a few tips to make your mug cake a success:
- Set your microwave on high and cook for 60 seconds. If your cake is set, take it out and let it cool slightly, add your toppings, and enjoy!
- Mug cakes can easily become over-baked and dense. You want your cake to be moist and slightly sticky on top, but not a gooey cake batter consistency.
- If your cake is not quite set after 60 seconds, cook it for 20 more seconds and recheck. Still not set? Cook for 10 more seconds. You can easily overcook your mug cake, so be cautious when adding additional cooking time.
- Mug cakes will rise while cooking in the microwave and then settle once it begins to cool.
