Heather’s Notes

• A Fresh Take on Fall Baking – Instead of the usual pumpkin, we use butternut squash puree for a smoother texture and naturally sweet flavor that pairs beautifully with spices.
• The Perfect Spice Blend – Ground cinnamon, nutmeg, and cloves give the cake that classic warm, spiced flavor that screams autumn baking.
• Super Moist Texture – Thanks to the squash puree and a touch of oil, this cake stays incredibly tender for days.
• Light Citrus Glaze – A drizzle of fresh clementine glaze adds brightness that balances the richness of the cake without overpowering the spice.
• Versatile for All Occasions – Serve it as a rustic loaf, a pretty bundt, or even cupcakes—this recipe adapts easily and always impresses.

Why You’ll Love Butternut Squash in Cake

Using butternut squash in baked goods isn’t just a clever way to sneak in a vegetable and it’s actually one of the best-kept secrets for ultra-moist, tender cakes. It has a velvety texture when pureed and a subtle sweetness that pairs beautifully with warm baking spices. Compared to pumpkin, it’s slightly more mellow and creamy, which makes this cake feel a little more elevated and unexpected.

And let’s talk about that glaze, fresh clementine juice gives it a bright, citrusy zing that enhances every bite. The aroma alone as it hits the warm cake will have you reaching for a slice before it even fully sets.

Ingredients to make Butternut Squash Cake

• Whole wheat pastry flour
• Baking powder
• Salt
• Ground cinnamon
• Ground nutmeg
• Ground cloves
• Butternut squash puree – homemade or canned
• Olive oil
• Granulated white sugar
• Brown sugar

For the Glaze:

• Icing sugar or powdered sugar

Substitution Ideas

Butternut Squash Purée

• Pumpkin Puree – A 1:1 substitute. It’s slightly earthier but still gives a moist, spiced cake texture.
• Sweet Potato Puree – Adds richness and sweetness. Just be sure it’s smooth and well-mashed.
• Carrot Purée – Boil or steam carrots until soft and blend into a purée for a similar result with a slightly lighter flavor.

Flour

• Gluten-Free Flour Blend – Use a 1:1 baking blend that contains xanthan gum to keep the texture close to traditional.
• Whole Wheat Flour – Sub up to half the all-purpose flour for whole wheat for a heartier, slightly nuttier cake.
• Spelt Flour – Offers a slightly sweet and nutty flavor. Use in place of all-purpose for a more rustic, wholesome twist.

Oil

• Vegetable Oil or Canola Oil – Use a light oil for the best tasting cake.
• Coconut Oil – A great dairy-free option with a mild flavor. Just make sure it’s melted and cooled slightly before mixing.

Spices

• Pumpkin Pie Spice – Replace the cinnamon, nutmeg, and cloves with 1½ teaspoons of pumpkin pie spice blend for convenience.
• Cardamom – Adds a beautiful floral spice note—use sparingly (about ⅛ teaspoon) in place of cloves or nutmeg.
• Ground Ginger – add 1/4 teaspoon ground ginger to give this delicious cake even more flavor.

Clementine Juice in Glaze

• Orange Juice – A great alternative with a slightly bolder citrus note.
• Lemon Juice – For a tangier glaze, use lemon juice—but reduce the quantity to taste so it doesn’t overpower the cake.
• Milk or Cream – If you’re out of citrus, use a few teaspoons of milk or cream for a simple vanilla glaze and add ¼ tsp vanilla extract.
• Cream Cheese Icing – this moist cake will hold up great to a smooth cream cheese icing. Use your favorite recipe. 

Instructions

1. Preheat oven to 350°F (175°C). Grease and flour a loaf pan or line with parchment paper.
2. In a medium bowl, or stand mixer with the whisk attachment, whisk together flour, baking powder, salt, cinnamon, nutmeg, and cloves. Set aside.
3. In a large mixing bowl, combine the brown sugar, granulated sugar, eggs, and oil. Mix on medium speed or whisk until smooth and well combined.
4. Add the butternut squash puree and vanilla extract, and mix until incorporated.
5. Fold in the dry ingredients just until no streaks remain, do not overmix.
6. Pour the batter into the prepared pan, place in preheated oven and bake for 40–50 minutes, or until golden brown and a toothpick inserted into the center comes out clean.
7. Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
8. Meanwhile, whisk together the powdered sugar and clementine juice (and zest if using) in a small bowl until a pourable glaze forms.
9. Once the cake is completely cool, drizzle with the glaze and let it set before slicing.
