These muffins use three cups of oats and no flour at all. That is the whole trick. The oats soften in milk and Greek yogurt, and the banana holds it together.
You need one bowl and about fifteen minutes of hands-on work. The oven does the rest in 30 minutes at 350 degrees F. The batter looks wet before it bakes. That is normal, and it is why the muffins come out moist instead of crumbly.
Twelve muffins, one standard tin. Eat a couple warm, then store the rest for breakfasts during the week.
Step-by-Step Instructions
1. Heat the oven
Set the oven to 350 degrees F (180 degrees C). Line a 12-cup muffin tin with paper liners.
2. Mash the bananas
Put the bananas in a medium bowl and mash them until smooth. A fork works fine.
3. Mix the wet ingredients
Stir in the eggs, maple syrup, salt, baking powder, vanilla, cinnamon and Greek yogurt. Mix until no streaks of yogurt are left.
4. Add oats and milk
Stir in the oats and the milk. The batter will look loose and wet at this point.
5. Let it stand
Leave the bowl alone for 5 to 10 minutes. The oats absorb the liquid and the batter thickens to an oatmeal-like consistency.
6. Fill the cups
Spoon the batter into the lined cups, about three quarters full each. Scatter your toppings on top and press them in gently.
7. Bake 30 minutes
Bake for 30 minutes, until the tops are set and spring back when you touch the center. A skewer in the middle should come out clean.
8. Cool and store
Cool in the tin for 5 minutes, then move the muffins to a rack. Once they are fully cool, keep them in an airtight container or freeze them in a bag.
Variations
Chocolate chip
fold 1/2 cup of chips into the batter at the end, before it stands.
Nut version
add 1/2 cup chopped walnuts or pecans with the toppings.
Less sweet
use sugar-free maple syrup, as some readers do, and expect a slightly drier crumb.

Frequently Asked Questions
Q: Can I use quick oats instead of rolled oats?
You can, but the texture changes. Quick oats soak up the milk faster, so skip most of the standing time and expect a softer, less chewy muffin.
Q: Why are my muffins wet in the middle?
Usually the batter went in before the oats finished soaking, or the oven is cooler than it reads. Give the batter its 5 to 10 minutes and check your oven with a thermometer.
Q: Do these need flour?
No. The oats and eggs do that job here. The muffins are denser than a flour muffin, closer to baked oatmeal in a paper cup.
Q: Can I make them without Greek yogurt?
Regular plain yogurt works, and the muffins come out a touch softer. Sour cream also works in the same amount.
Q: How do I know they are done without a timer?
Press the center of one muffin. It should spring back and feel firm, not spongy. A skewer inserted in the middle should come out clean.
