Soft, moist cinnamon banana bread muffins rolled in a buttery cinnamon sugar coating, like a cross between banana bread and a snickerdoodle in muffin form.

If you love banana bread but wish it came in a grab and go form with a little cinnamon sugar crunch on top, these cinnamon banana bread muffins are about to become your new obsession. They start with a rich, ultra moist banana bread base, the kind made with very ripe bananas and a touch of sour cream, then take a detour through melted butter and a cinnamon sugar coating while still warm from the oven. The result is something between classic banana muffins and a snickerdoodle, soft and tender in the middle with a slightly crackly, sweet cinnamon crust on the outside.
These are sometimes called snickerdoodle banana muffins for exactly that reason. Every bite gives you warm banana flavor, a hint of vanilla, and that unmistakable cinnamon sugar finish that makes people ask for the recipe before they have even finished chewing.
Before we get cooking, the right tools and ingredients make a real difference here. A sturdy muffin tin helps the muffins bake evenly and release cleanly, and using real butter rather than oil for both the batter and the coating gives these banana churro muffins their signature richness and that golden cinnamon crust.
There are a few small details that separate an average banana muffin from one that people remember.
Chef's Tip: Resist the urge to overmix the batter. Stir just until the flour disappears. Overmixed banana muffin batter develops gluten and can turn your muffins tough or gummy instead of soft and fluffy.
The cinnamon sugar shell is really what turns this into a cinnamon banana bread muffins recipe worth bookmarking. As soon as the muffins are cool enough to handle, usually about 5 minutes out of the oven, dip the domed top into melted butter, then roll it directly in a bowl of cinnamon and sugar. Work in batches so the butter stays warm and the coating sticks evenly.
If you want an even bolder cinnamon flavor, you can add an extra half teaspoon of cinnamon to the coating mixture, or lightly dust the muffin tops a second time once they have cooled for a few minutes.
Ready to make it? Here is the full step by step recipe for these cinnamon sugar banana muffins:

Soft, moist cinnamon banana bread muffins rolled in a buttery cinnamon sugar coating, like a cross between banana bread and a snickerdoodle in muffin form.
Preheat the oven to 375 degrees F (190 degrees C) and grease a 12-cup muffin tin well or line with paper liners.
In a medium bowl, whisk together the flour, baking soda, baking powder, 1 teaspoon of the cinnamon, and salt.
In a large bowl, mash the bananas until mostly smooth. Whisk in the melted butter, sugar, eggs, vanilla, and sour cream until well combined.
Pour the wet ingredients into the dry ingredients and fold gently with a spatula until just combined. Do not overmix, a few small lumps are fine.
Divide the batter evenly among the muffin cups, filling each about three quarters full.
Bake for 18 to 20 minutes, until a toothpick inserted in the center comes out clean or with just a few moist crumbs.
While the muffins bake, stir together the remaining sugar and cinnamon in a shallow bowl for the coating, and melt a few extra tablespoons of butter in a separate small bowl.
Let the muffins cool in the tin for 5 minutes, then while still warm, dip the top of each muffin in melted butter and roll it in the cinnamon sugar mixture.
Set the coated muffins on a wire rack to finish cooling slightly before serving.
These muffins are best enjoyed the day they are coated, still slightly warm, with a cup of coffee or tea. That said, they hold up nicely for a few days if stored properly.
If you are wondering how to make banana muffins with cinnamon a little more nutty or textured, try folding in a half cup of chopped walnuts or pecans into the batter. For a fall twist, swap a quarter teaspoon of the cinnamon in the coating for pumpkin pie spice.
Chef's Tip: Freeze any extra very ripe bananas ahead of time. Thawed frozen bananas are actually even softer and sweeter, making them perfect for banana and cinnamon muffins whenever the craving hits.
However you serve them, these muffins deliver everything you love about banana bread in a cinnamon sugar coated, handheld package that disappears from the kitchen counter fast.
