These muffins take about 15 minutes in a 375°F oven and make 12. You mash two bananas, stir two bowls together, and you're done.
The batter is whole wheat flour, rolled oats, Greek yogurt and natural peanut butter. That's a heavier mix than a boxed muffin, so don't expect a light cake crumb. Expect something filling you can eat in the car.
One thing to know before you start: mash the bananas until almost no lumps are left. Big chunks leave wet pockets and the muffins bake unevenly.
Step-by-Step Instructions
1. Heat the oven
Set the oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners.
2. Mix the dry ingredients
In a medium bowl, stir together the flour, oats, baking powder, baking soda, cinnamon and salt. Break up any oat clumps with your fingers.
3. Mash and mix the wet
In a second bowl, mash the bananas until smooth. Add the peanut butter, honey, Greek yogurt, almond milk, egg and vanilla, then stir until even.
4. Combine the two bowls
Pour the wet mix into the dry bowl. Stir just until no dry flour shows. A few lumps are fine, and overmixing makes the muffins tough.
5. Fill the cups
Spoon the batter into the liners, about three quarters full each. You should get 12 muffins.
6. Bake
Bake for 15 minutes. The tops should spring back when pressed and a toothpick should come out nearly clean.
7. Cool
Leave the muffins in the tin for 5 minutes, then move them to a rack.
8. Make the drizzle
Stir the peanut butter, honey and almond milk together until smooth. Add the milk a little at a time until it pours.
9. Finish the muffins
Spoon the drizzle over the cooled muffins and scatter crushed peanuts on top if you're using them.
How to Store Peanut Butter Banana Oatmeal Muffins
Refrigerator
Keep the muffins in a sealed container in the fridge for up to 4 days. The drizzle stays soft, so stack them in one layer or put parchment between them.
Freezer
Freeze the muffins without the drizzle for up to 2 months. Wrap each one, then bag them. Add the drizzle after thawing.
Reheating
Warm a muffin in the microwave for 20 to 30 seconds. Longer than that and it goes rubbery.
Tips & Tricks
- Mash the bananas in the wet bowl first, then add everything else. It's easier than mashing around peanut butter.
- Fill each muffin cup about three quarters full. Overfilling makes the tops spill over the liner.
- The muffins are done when the tops spring back when you press them lightly, or a toothpick in the center comes out with just a crumb or two.
- Let the muffins cool in the tin for 5 minutes, then move them to a rack. Leaving them in the hot tin steams the bottoms.
- If you only have a loaf pan, the batter works there too, but it needs about 35 minutes instead of 15.
Variations
Chocolate chip version
fold in a half cup of chocolate chips with the dry ingredients. This is a change to the original recipe, not part of it.
Loaf version
bake the same batter in a loaf pan for about 35 minutes. Check with a toothpick near the center.
No Greek yogurt
use the same amount of plain yogurt or sour cream. The texture will be a little looser.
Frequently Asked Questions
Q: Can I use quick oats instead of rolled oats?
You can, but the muffins come out softer and less chewy. Rolled oats hold their shape better in the batter.
Q: Why did my muffins come out dry?
Usually too much flour or too long in the oven. Spoon the flour into the cup instead of scooping, and pull the muffins at 15 minutes.
Q: Do I have to add the drizzle?
No. The muffins work plain, and they pack better for lunches without it. The drizzle is what makes them taste like a treat.
Q: Can I skip the honey?
You can cut it, but the muffins will taste flat since honey is the only sweetener. Very ripe bananas help make up for it.
Q: How do I know the muffins are baked through?
Press the top lightly. It should spring back. A toothpick in the center should come out with a crumb or two, not wet batter.
