Illustrated batch of golden-brown oat muffins with crumbly tops in paper liners

These are the muffins we bake most often. They’re not a treat, just a dependable breakfast. Everything goes into the blender, and twenty minutes later you have a dozen soft, banana-sweet muffins that freeze beautifully for busy weeks.

There’s no flour and no butter. The blender grinds rolled oats into flour as it mixes, ripe bananas do most of the sweetening, and a little maple syrup rounds out the flavor. They’re naturally dairy-free, and gluten-free when you use certified gluten-free oats.

Oat muffins have a softer, moister crumb than wheat muffins, and they need a short rest in the blender before baking. The method below explains why that step matters.

Why this recipe works

The blender makes oat flour
Blending turns whole oats into flour right in the jar, so there's no flour to measure and the muffins are naturally gluten-free when you use certified gluten-free oats.
The rest thickens the batter
Oats absorb liquid slowly. Ten minutes in the jar thickens the batter so the muffins dome nicely instead of spreading flat.
Bananas do double duty
Ripe bananas sweeten, add moisture and help bind the muffins, which lets us use only a quarter-cup of maple syrup and no butter.

How to know it’s done

The tops are domed, golden and spring back when gently pressed.
A toothpick in the center comes out clean, apart from melted chocolate.
The internal temperature reads 200°F (93°C).

Tips for success

The riper the bananas, the sweeter the muffins. Use bananas with plenty of brown spots.
These are softer and moister than flour-based muffins and firm up as they cool, so let them cool before you judge the texture.

Swaps & variations

Egg-free: Use 2 flax eggs (2 tablespoons/14 g ground flaxseed mixed with 6 tablespoons water, rested 5 minutes). The muffins will be denser and more delicate.
Honey: Use the same weight (80 g) of honey in place of maple syrup. The muffins will brown a little faster.

Make ahead, storage & reheating

Make ahead: Bake a batch on Sunday and freeze. Take one out the night before and it'll be thawed by breakfast.
Store & reheat: Keep in an airtight container at room temperature for 2 days, in the fridge for up to 5 days, or frozen for up to 3 months. Microwave a frozen muffin for 30 to 40 seconds.

Frequently asked questions

Are these muffins gluten-free?

They're gluten-free when made with oats labeled certified gluten-free and baking powder that's also gluten-free. Regular oats are often contaminated with wheat during processing.

Can I use quick oats?

Yes. Use the same weight (225 g). They blend even more easily.
