You know those bananas sitting on your counter, getting browner and spottier by the day? They’re not a problem—they’re an opportunity. And these banana nut muffins are the best way to seize it.
These muffins are everything you want in a banana baked good: incredibly moist, deeply flavorful, and just sweet enough. The addition of toasted walnuts adds a wonderful crunch and nutty depth that perfectly complements the sweet banana.
They’re like banana bread’s portable, portion-controlled cousin, with slightly crisp edges and tender, domed tops. Whether you’re packing lunches, hosting a brunch, or just treating yourself, these muffins deliver pure comfort in every bite.
Yields 12 standard muffins or 6 jumbo muffins.
Step-by-Step Instructions
Preheat and Prepare
Preheat your oven to 375°F (190°C). Line a 12-cup muffin pan with paper liners or grease the cups thoroughly.
Toast the Walnuts
Spread the walnuts on a baking sheet and toast in the preheating oven for 5-7 minutes, until fragrant and lightly golden. Watch carefully—they can burn quickly. Remove and set aside to cool. Chop coarsely.
Combine Dry Ingredients
In a medium bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon (if using). Set aside.
Cream Butter and Sugars
In a large bowl, beat the softened butter, granulated sugar, and brown sugar together with an electric mixer until light and fluffy, about 2-3 minutes. Scrape down the sides as needed.
Add Wet Ingredients
Add the eggs one at a time, beating well after each addition. Scrape down the bowl again.
Beat in the vanilla extract.
Add the mashed bananas and sour cream, and mix until combined. The mixture may look slightly curdled—that’s perfectly normal.
Combine Wet and Dry
Gradually add the dry ingredients to the wet ingredients, mixing on low speed or folding with a spatula until just combined. Do not overmix—a few streaks of flour are fine.
Fold in the toasted chopped walnuts, reserving a handful for topping if desired.
Fill the Muffin Cups
Scoop the batter into the prepared muffin cups, filling them almost to the top (about ¾ full for standard muffins, full for jumbo). This helps create those domed tops.
If reserved, sprinkle the extra walnuts and a pinch of turbinado sugar over the tops of each muffin.
Bake
Bake for 18-22 minutes for standard muffins, or 22-26 minutes for jumbo muffins, until a toothpick inserted into the center comes out clean or with a few moist crumbs.
Let the muffins cool in the pan for 5-10 minutes, then transfer to a wire rack to cool completely. Serve warm or at room temperature.

Storage and Make-Ahead Tips
How to Store:
Store banana nut muffins in an airtight container at room temperature for up to 4 days. The moisture from the bananas keeps them soft. For longer storage, refrigerate for up to a week.
Can You Freeze Muffins?
Absolutely! Muffins freeze beautifully. Cool completely, then place in a freezer bag or airtight container with parchment between layers. Freeze for up to 3 months. Thaw at room temperature or microwave for 20-30 seconds.
Reviving Day-Old Muffins:
To refresh muffins, microwave for 10-15 seconds or warm in a 300°F oven for 5-7 minutes. They’ll taste almost freshly baked!
Make-Ahead for Breakfast:
These muffins are actually better the next day as the flavors meld. Make them a day ahead and store at room temperature. Perfect for stress-free breakfasts.
Freezing Banana Puree:
If you have overripe bananas, peel and freeze them in a zip-top bag. Thaw and use directly in muffin batter—they’ll be even softer and more flavorful.
Frequently Asked Questions
Can I use frozen bananas?
Yes! Frozen bananas work perfectly. Thaw them completely, then mash them with a fork. They’ll be very soft and may release some liquid—that’s fine, just include it in the batter.
Can I make these without nuts?
Absolutely! Simply omit the walnuts. The muffins will still be delicious. You can also substitute with chocolate chips, dried fruit, or leave them plain.
Can I use other nuts?
Yes! Pecans, almonds, or hazelnuts all work beautifully. Toast them first for the best flavor. Macadamia nuts would also be delicious.
Why are my muffins dense instead of light?
Dense muffins usually mean overmixing or too much flour. Mix just until the flour disappears, and measure your flour correctly (spoon and level, don’t scoop). Overmixing develops gluten, which makes muffins tough.
Can I reduce the sugar?
You can reduce the sugar to ¾ cup total, but keep in mind that bananas provide natural sweetness. If your bananas are very ripe and sweet, you can reduce slightly without issue. The brown sugar adds moisture as well as sweetness.
Can I make these into banana bread?
Yes! Pour the batter into a greased 9×5 inch loaf pan and bake at 350°F for 50-60 minutes. This recipe makes one standard loaf of banana nut bread.
Can I use whole wheat flour?
You can substitute up to half of the all-purpose flour with whole wheat flour. Whole wheat absorbs more liquid, so you may need to add an extra tablespoon of sour cream or milk.
Why did my muffins sink in the middle?
A sunken middle usually means the muffins were underbaked or the oven temperature was too low. Make sure your oven is properly preheated and bake until a toothpick comes out clean. Overmixing can also cause sinking.
Can I add cinnamon?
Absolutely! Cinnamon and banana are a wonderful combination. Add 1-2 teaspoons of ground cinnamon to the dry ingredients. Nutmeg or cardamom would also be delicious.
How do I get those beautiful domed tops?
Fill the muffin cups almost to the top, use room temperature ingredients, and make sure your baking powder and soda are fresh. Starting at 375°F (rather than lower) also helps create that initial rise.
Can I make these dairy-free?
Yes! Use vegan butter and substitute the sour cream with a dairy-free yogurt or coconut cream. The texture will be slightly different but still delicious.
How ripe should the bananas be?
The riper, the better! You want bananas with brown spots or completely black peels. They should be soft and smell very banana-y. Green or yellow bananas won’t give you the same flavor or moisture.
Can I add a streusel topping?
Absolutely! A simple streusel of ½ cup flour, ¼ cup brown sugar, ¼ cup melted butter, and ½ teaspoon cinnamon sprinkled on top before baking takes these muffins to the next level.
