Being that this is a Veg World (after all), you probably could have guessed that I’m a big fan of putting vegetables in just about anything. That includes muffins and other baked goods.
Take my Zucchini Carrot Oat Muffins for example. They’re one of the most loved recipes on the site, so I can’t be the only one who likes veggies in her muffins! Or the Fudgy Beet Brownies and Carrot Banana Breakfast Bread. Two of my favs!
And now I’m adding these Spiced Oat and Butternut Squash Muffins to the list. They’re such a fun recipe for this time of year, and easy to make too!

Reasons to Love Squash Muffins
- They’re a tasty and untraditional way to get more fiber, vitamins A and C (hello, strong immune system), and iron and calcium from butternut squash!
- They’re a good alternative to pumpkin-based baked goods, which get a little too much hype sometimes.
- You can freeze them for busy weeks! Meal prep, for the win.
- A little bit of maple syrup helps bring out the natural sweetness of butternut squash. And with pumpkin pie spice on top of that, the flavor is simply delicious!

How to Make Butternut Squash Muffins – Step by Step
Just like any other muffin, you make these veggie-loaded ones by whisking together the “wet” ingredients (photo 1 below) and stirring in the “dry” ones with a rubber spatula or whisk (photos 2 and 3).
The wet ingredients in these muffins include pureed or mashed butternut squash, maple syrup, and whole milk Greek yogurt and olive oil for some added nutrition and moisture. And of course, we’ve got flour, oats, and pumpkin spice for the dry ones!
Once the batter is thoroughly mixed (it should be a little lumpy), use an ice cream scoop or spoon to fill up the muffin tin (very close to the top for each muffin – see photo 4). Bake for 19-23 minutes at 400, and you’re done.
Expert Tips for Perfect Muffins
- Ingredients: I used canned butternut squash puree (like this kind from Farmer’s Market Foods), which can be found at most grocery stores right by the canned pumpkin. You can also use mashed, cooked (roasted or boiled) butternut squash. See my post on How to Make Butternut Squash Puree to learn how to make it yourself at home. To make these butternut squash muffins gluten free, sub all-purpose gluten free flour for regular flour and use gluten free old-fashioned oats.
- Additions: Feel free to add ¼-1/2 cup of nuts (i.e. pecans) or chocolate chips to the batter before baking!
- Serving: For extra pretty muffins, you can swirl some leftover butternut squash on top of the muffins before baking with a fork (like in photo 4 above) or sprinkle cinnamon or brown sugar on top before putting them in the oven. They taste delicious cold or warm. I like to heat them up under the broiler and add some butter or peanut butter.
- Storage: Store at room temp in an airtight container for 2-3 days. Put the container in the fridge to extend the shelf life by a few more days. To freeze for later, transfer them to a freezer or Stasher bag. They should last for 3 months. Thaw in the fridge before eating.

Made this with leftover roasted squash. Didn’t have some of the ingredients on hand so I substituted sour cream for the yogurt, steel cut oats for the old fashioned and used cinnamon and nutmeg instead of pumpkin pie spice. Turned out wonderfully! Will definitely make again. Thanks for the recipe.
