Butternut Squash Banana Muffins

The smell of roasted butternut squash lingered in my kitchen one November afternoon, and rather than let it go to waste, I mashed it into a banana bread batter that was already halfway done. What came out of the oven was something neither squash bread nor banana bread could ever be on their own: a muffin so tender and warmly spiced that I made a second batch before the first one cooled. These butternut squash banana muffins have been my go-to whenever the fridge holds leftover squash and the fruit bowl has bananas past their prime. They are simple, forgiving, and endlessly adaptable.

My neighbor stopped by unannounced one weekend while I was pulling a tray of these from the oven, and she ended up sitting at my counter eating three of them with butter while telling me about her daughters wedding plans. I sent her home with the remaining six, and she texted me that night asking for the recipe. That is the kind of muffin this is: unpretentious, disarming, and impossible to eat just one of.

Ingredients

• 1 cup butternut squash puree (from roasted squash): Roasting concentrates the natural sugars far better than steaming, and the caramelized depth is worth the extra minutes.
• 2 ripe bananas, mashed: The speckled, nearly black ones you almost threw away are exactly what you want here for maximum sweetness.
• 2 cups all-purpose flour: Spoon and level rather than scooping to avoid dense, heavy muffins.
• 1 tsp baking powder and 1 tsp baking soda: The dual leavening gives a reliable rise even with the dense squash and banana.
• 1/2 tsp salt: Do not skip this, as salt is what makes the spices and sweetness come alive.
• 1 tsp ground cinnamon and 1/2 tsp ground nutmeg: Freshly grated nutmeg will knock your socks off compared to the pre-ground jar.
• 2 large eggs: Room temperature eggs blend more smoothly into the batter.
• 1/2 cup brown sugar, packed, and 1/4 cup granulated sugar: The brown sugar adds molasses warmth while the granulated keeps the crbal delicate.
• 1/3 cup vegetable oil (or melted coconut oil): Oil keeps these muffins tender for days longer than butter would.
• 1 tsp pure vanilla extract: A small pour that quietly ties every flavor together.
• 1/2 cup chopped walnuts, pecans, or chocolate chips (optional): Pick one or mix them all depending on who is at your table.

Instructions

Get the oven ready:

Preheat your oven to 350 degrees F and line a 12-cup muffin tin with paper liners or give each cup a quick spray of baking spray.

Whisk the dry team:

In a large bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg until evenly distributed and fragrant.

Bring the wet ingredients together:

In a medium bowl, beat the eggs with both sugars until smooth, then stir in the oil, vanilla, mashed bananas, and squash puree until you have a gorgeous orange mixture.

Marry wet and dry:

Pour the wet mixture into the dry and fold gently with a spatula just until you no longer see dry flour streaks, as overmixing is the enemy of a tender crumb.

Add your extras:

Fold in nuts or chocolate chips now if you are using them, distributing them with just a few confident strokes.

Fill the tins:

Divide the batter evenly among the cups, filling each about three quarters full so they have room to crown beautifully.

Bake until golden:

Bake for 22 to 25 minutes, checking with a toothpick at the center of one muffin, which should come out clean with just a few moist crumbs clinging.

Cool with patience:

Let the muffins rest in the pan for five minutes, then transfer them to a wire rack to cool completely so the bottoms do not steam and turn soggy.

Save

The morning I packed these into my daughters lunchbox for the first time, she came home and told me her friend traded an entire bag of goldfish crackers for just one of them. I have been sending extras ever since, and somehow that small exchange made these muffins feel like a little love letter tucked between the sandwich and the apple.

Making Your Own Squash Puree

Peel and cube a medium butternut squash, spread the pieces on a parchment-lined baking sheet, and roast at 400 degrees F for about 30 minutes until fork-tender and caramelized at the edges. Transfer to a blender or food processor and blend until silky smooth, scraping down the sides as needed. Any leftover puree freezes beautifully in an airtight container for up to three months, so you can make these muffins on a whim long after squash season ends.

Swaps and Substitutions

You can replace up to half the all-purpose flour with whole wheat flour for added fiber and a slightly nuttier flavor that pairs wonderfully with the squash. Coconut oil works seamlessly in place of vegetable oil, and maple syrup can stand in for the granulated sugar if you want a deeper, more autumnal sweetness. For a nut-free version, simply skip the walnuts or swap them for sunflower seeds, which give a similarly satisfying crunch.

Storage and Freezing

These muffins stay fresh on the counter in an airtight container for up to three days, though in my house they rarely last that long. For longer storage, freeze them individually wrapped in plastic and tucked into a freezer bag for up to three months. A quick 30-second spin in the microwave brings them back to that just-baked softness.

• Sprinkle oats or pumpkin seeds on top before baking for a crunchy, bakery-style finish.
• A pinch of extra cinnamon sugar on the muffin tops creates a sweet crust that is absolutely irresistible.
• Always let them cool completely before freezing so condensation does not make them soggy.

Save

Keep a batch of squash puree in your freezer and you are never more than forty minutes away from a kitchen that smells like everything good about fall. These muffins ask almost nothing of you and give back so much warmth in return.

Recipe FAQs

→ How do I roast butternut squash for the puree?

Peel and cube squash, toss with a little oil and roast at 400°F (200°C) for about 30 minutes until tender. Blend or mash until smooth, adding a splash of water if too thick.

→ Can I swap the all-purpose flour for whole wheat?

Yes — substitute half the all-purpose flour with whole wheat for more fiber. Expect a slightly denser crumb; use a touch more liquid if batter seems stiff.

→ What keeps the muffins moist?

The combination of mashed banana, roasted squash puree and oil provides moisture. Avoid overmixing the batter and bake just until a toothpick comes out clean to prevent dryness.

→ How should I store leftover muffins?

Cool completely, then store in an airtight container at room temperature for 2 days or refrigerate up to 5 days. Rewarm briefly before serving for best texture.

→ Can I add mix-ins like nuts or chocolate?

Yes — fold in up to ½ cup chopped walnuts, pecans or chocolate chips at the end. Nuts add crunch; chocolate gives a sweeter contrast to the squash and banana.

→ Any tips for a gluten-free version?

Use a one-to-one gluten-free flour blend that contains xanthan gum, and check that all other ingredients are certified gluten-free. Texture will vary slightly from the original.
