Why Youโll Love This Recipe
Every fall, I dive (head first) into an ever-growing collection of fresh and canned pumpkin recipes (24 easy vegan canned pumpkin recipes here), often touting butternut squash as a great substitute. But this winter squash also deserves some dessert limelight! Like pumpkin, butternut squash cake has heaps of natural sweetness (arguably even more than pumpkin) and moisture while still remaining fluffy and tender. Plus, this recipe is egg-free and dairy-free for everyone to enjoy.
This recipe is so easy to throw together, too, and uses just 10 ingredients, with fresh or canned squash puree. Whether you add a decadent layer of vegan cream cheese frosting, a simple dusting of powdered sugar, or enjoy it as is (perfect for breakfast!), this butternut squash dessert (also great at breakfast/brunch) is a crowd-pleasing treat.

How to Make Butternut Squash Cake
Step 1: Preheat the oven to 350F/180C and lightly grease a 9-inch round baking pan. Then, in a large bowl, whisk the plant milk and apple cider vinegar until it thickens, like buttermilk. Add the oil, brown sugar, and vanilla extract, and mix well until the sugar is almost fully dissolved.
Step 2: Then, mix in the butternut squash puree. In a separate bowl, mix the flour, baking powder, baking soda, salt, and pumpkin spice. Add the dry ingredients to the wet one and mix until combined, but be careful not to over-mix the batter.
Step 3: Pour the butternut cake batter into the prepared pan, smooth the top with a spatula, and bake for 25-30 minutes. Moist crumbs are fine but no wet batter. Remove the butternut squash cake from the oven and let it cool completely over a cooling rack before removing it from the pan. Optionally, frost, slice, and enjoy!
FAQs
To make enough squash puree for this butternut squash dessert recipe, either roast the butternut squash OR place 2 cups of cubed butternut squash in a saucepan covered with water. Bring to a boil over high heat, then reduce to a simmer and cook for 20 minutes or until tender (time will vary based on the cube size).
Then, thoroughly drain and leave it to cool before pureeing with an immersion blender, blender, or food processor.
I havenโt tried, though itโs very likely you could sub the AP flour 1:1 with a gluten-free AP blend, like Bobโs Red Mill or King Arthurโs.
Yes, you can use an 8-inch square pan, which has the same capacity. A slightly larger pan would work, too, though the vegan cake will be thinner and may require less time to bake through. A 9×5-inch loaf pan would also work but requires a higher baking time to bake through.
Pro Recipe Tips
- Measure the flour correctly: To avoid ending up with dense bakes, first, fluff it in its bag, spoon it into the measuring cup, then level the top with the back of a knife.
- Avoid over-mixing: Over-mixing batter overworks the gluten in the flour and leads to dense, rubbery cakes. Mix until โjustโ combined โ a few small lumps are fine.
Storage Instructions
Store the cooled squash cake in an airtight container at room temperature for 2-3 days or in the refrigerator (especially if frosted!) for 5-7 days.
You can also freeze the cake, whole or sliced (with parchment between the slices to avoid sticking), for up to 3 months. Thaw in the refrigerator overnight.
