How to Make 3 Ingredient Banana Oat Muffins

1. Prepare the Oven

Preheat your oven to 350°F (175°C). Generously grease a mini muffin pan.

Because these muffins don’t contain flour, eggs, or baking powder, they don’t rise much during baking. A greased pan also makes them easier to remove.

2. Mash the Bananas

Place the ripe bananas in a large mixing bowl and mash them until mostly smooth.

A few small pieces of banana are perfectly fine and can add extra texture.

3. Add the Oats and Vanilla

Add the oats and vanilla extract to the mashed bananas. Stir until everything is thoroughly combined.

The mixture should be moist and hold together when spooned into the muffin pan.

4. Add Your Favorite Mix-Ins

If you’re using chocolate chips, chopped nuts, raisins, cinnamon, coconut, dried fruit, or another mix-in, gently fold it into the banana-oat mixture.

Chocolate chips are especially delicious with these muffins.

5. Fill the Muffin Pan

Spoon the mixture into the greased mini muffin cups, filling them close to the top.

Since the muffins don’t rise significantly, you don’t need to leave as much room as you would with traditional muffin batter.

6. Bake

Bake for 15–18 minutes, or until the muffins are set and lightly golden.

7. Cool

Allow the muffins to cool in the pan for about 5 minutes, then carefully remove them and transfer them to a cooling rack.

How to Make Different Flavors in One Batch

Want several flavors without making multiple batches?

Fill the mini muffin cups about halfway with the banana-oat mixture. Add a few different mix-ins to individual cups, then cover with more batter and finish with another sprinkle of the chosen topping.

This lets you make several varieties from one simple base.

Recipe Tips

Use very ripe bananas.
The riper the bananas, the sweeter and more flavorful your muffins will be.

Don’t use traditional paper liners.
The original recipe notes that the mixture tends to stick to paper baking cups, so generously greasing the mini muffin pan works better.

Use a mini muffin pan.
These muffins are dense and don’t rise much, making the smaller size ideal for snacking and lunchboxes.

Don’t expect traditional muffin texture.
Without flour, eggs, or baking powder, these are naturally denser and chewier than conventional muffins.

Storage

Store cooled muffins in an airtight container in the refrigerator for up to 5 days.

They make a convenient grab-and-go breakfast or snack throughout the week.

Frequently Asked Questions

Can I Make These Sweeter?

The basic recipe relies on ripe bananas for sweetness. If you prefer a sweeter muffin, you can add a little brown sugar, maple syrup, or honey.

Chocolate chips or raisins are another easy way to add sweetness without changing the base recipe.

Can I Use Regular Muffin Cups?

A mini muffin pan is recommended because these muffins are dense and don’t rise much. If you use paper liners, they may stick to the muffins, so greasing the pan well is the better option.
