Like many families, mine cherishes a collection of beloved traditional desserts – sweet confections that have graced our tables for as long as I can remember, lovingly prepared by my mom. These classic, comforting recipes truly shine during the holiday season, a time when my mom transforms into an exceptionally prolific baker. As early as December rolls around, she meticulously plans and begins baking our family’s customary array of holiday treats. Her foresight extends to drafting holiday dinner menus weeks in advance, ensuring every possible task is completed long before the festive rush. She’s an unparalleled planner (a habit I gratefully inherited!), and while she always seeks new culinary inspiration, these time-honored dishes frequently reappear, often by popular demand from us, her eager family.
Every year, I eagerly volunteer to assist my mom with the holiday preparations. I relish our conversations about menu planning, and on the actual day of our festive dinner, I love sharing the joyful responsibility of setting a beautiful table, presenting artfully arranged plates, and, of course, taking a little credit for contributing to everyone’s happiness around the table. Most often, I offer to prepare dessert, as it’s my true culinary passion and an area where I believe I’ve honed my skills considerably. My mom always graciously accepts my offer, yet she can never resist serving her own classic cookies and bars alongside whatever elaborate creation I’ve concocted. To be perfectly honest, her traditional treats often steal the spotlight. I know my desserts are delicious, and she certainly doesn’t mean to overshadow my efforts, but during the holiday season, the comfort of tradition frequently triumphs.
Driven by this friendly competition and a continuous quest for culinary excellence, I dedicate time each year to experimenting with new recipes, hoping that some will eventually carve out their own cherished place within our family’s traditions. My lifelong obsession with vibrant citrus fruits consistently fuels my creativity, especially during the colder months. Many of my long-time favorite citrus desserts for winter have sprung to life during these end-of-year brainstorming sessions. These include an effortlessly delicious orange yogurt cake, an elegantly classic French lemon tart, and a truly spectacular lemon and olive oil cake topped with toasted meringue. Each year, I strive to introduce a dessert that combines innovative flavors with a comforting familiarity, aiming to create a new classic for the next generation.
It was a few years ago that inspiration struck, leading me to create these incredibly tender, wonderfully aromatic, and utterly adorable clementine squash cupcakes. They were an instant hit, quickly earning their place as a new family favorite. The idea of incorporating squash came to me as I considered carrots and pumpkin – two savory ingredients frequently used in baking to impart exceptional moisture and tenderness to cakes. With a butternut squash readily available, I decided to grate and use it just as I would carrots. Since it was the heart of winter, I also had a generous crate of sweet clementines in my fridge. Combining these two seasonal stars, I added a touch of pure maple syrup as a natural sweetener, resulting in a perfectly balanced and uniquely flavored cupcake.
These exquisite clementine squash cupcakes harmoniously blend classic winter flavors into irresistible tiny bites that are always the first to disappear from any serving plate. The grated squash ensures an incredibly moist and tender crumb, while the clementines introduce a delightful zestiness and bright citrus aroma. The maple syrup, subtly incorporated into the frosting, bestows an irresistible, warm fragrance and a delicate sweetness. But perhaps the most appealing aspect of this winning recipe is its convenience: you can bake the cupcakes, pipe on the elegant maple Italian meringue buttercream, and then freeze them completely assembled. This all-around winning recipe has truly become a cherished classic in my household – my son even makes a point of requesting them for his birthday parties, a true testament to their popularity!
Don’t feel you need to wait for the next holiday season to whip up a batch of these sensational clementine squash cupcakes. Their charming appearance and delightful flavor make them the perfect dessert for all anniversaries, parties, and special occasions throughout the year. During the warmer months, feel free to adapt the recipe by using other vibrant citrus fruits to replace seasonal clementines. You can even swap in good old carrots for the grated squash, creating a delightful variation (refer to my helpful tips below for detailed substitution instructions). However, there’s one crucial component you should never skip: that utterly incredible maple Italian meringue buttercream. It’s so luxuriously silky, rich, and elegantly smooth that you’ll be tempted to eat it straight by the spoonful!
Helpful Tips for Mastering Your Clementine Squash Cupcakes
Clementine Substitutions: What to Use When Clementines Aren’t Available
Aromatic clementines are a fantastic addition to a wide array of desserts, from chocolate chip cookies to delicate French macarons! They are, however, seasonal, typically gracing grocery store shelves from late November to early March. If you find yourself without clementines, don’t despair! You can easily use any member of the orange family as a substitute. Mandarins are the most obvious choice due to their similar size and flavor profile to clementines. Tangerines and even common Navel oranges also work wonderfully. The key is to ensure that the total amount of zest and fruit flesh you collect from your chosen substitute citrus fruits is equivalent to the quantities specified in the original recipe. For more precise measurement guidance and substitution tips, be sure to refer to the detailed notes within the recipe below.
Can Carrots Be Substituted for Squash in This Recipe?
Absolutely! For a slightly different flavor profile that still delivers incredible moisture, you can successfully substitute the same measured amount of finely grated carrots for the squash. Carrots are a fantastic alternative, especially if you prefer their classic sweetness in baked goods.
Understanding Italian Meringue Buttercream: A Silky Delight
Italian Meringue Buttercream (IMBC) is renowned for its incredibly silky, rich, and exceptionally smooth texture. The process of making it involves a specific technique: you first cook a sugar syrup to a precise temperature, then gradually stream this hot syrup into whipped egg whites, creating a stable and glossy meringue. Finally, soft, room-temperature butter is gradually beaten into this meringue, transforming it into a luxurious buttercream. What sets IMBC apart is its reduced sweetness compared to conventional buttercream frostings; the primary source of sugar comes from the cooked syrup, resulting in a more balanced flavor profile. There are several compelling reasons why Italian Meringue Buttercream is worth the extra effort: it’s remarkably stable, holds its shape beautifully even in warmer conditions, and unlike many other buttercreams, it doesn’t form a crust upon resting, maintaining its smooth consistency. Its stability also makes it an ideal frosting for intricate piping and elegant cake decorating.
Italian Meringue Buttercream vs. Swiss Meringue Buttercream: What’s the Difference?
While Italian Meringue Buttercream (IMBC) and Swiss Meringue Buttercream (SMBC) yield very similar textures and consistencies—both being smooth, light, and less sweet than traditional American buttercream—their preparation methods differ notably. As mentioned, IMBC is made by boiling a sugar syrup to a specific temperature and then slowly pouring it into already whipped egg whites. In contrast, for Swiss Meringue Buttercream, egg whites and sugar are whisked together over a pot of simmering water (a bain-marie) until the mixture reaches a certain temperature and the sugar fully dissolves. This gentle heating creates a stable meringue, to which butter is then incorporated. Both methods result in a glorious, stable buttercream, but the Italian method typically offers a slightly more robust and glossy meringue foundation.
Why Does Italian Meringue Buttercream Have a Pronounced Buttery Flavor?
Italian meringue buttercream inherently contains significantly less sugar compared to many other butter-based frostings, such as American buttercream. This lower sugar content allows the natural, rich flavor of the butter to truly shine through. Because the butter’s taste is more prominent in IMBC’s creamy, silky texture, it’s highly recommended to use the highest quality butter you can afford. European-style butters, often churned to a higher fat content, and cultured butters (which have a subtly tangy, more complex flavor) tend to produce especially exquisite results. A good rule of thumb is this: if you genuinely enjoy the flavor of a small knob of a particular type of butter on its own, then your Italian meringue buttercream made with that butter will undoubtedly taste amazing and elevate your dessert.
Can I Freeze These Delicious Clementine Squash Cupcakes?
You absolutely can! This is one of the fantastic features of this recipe, making it perfect for meal prepping ahead of special events or simply enjoying fresh cupcakes whenever a craving strikes. I highly recommend freezing the fully decorated cupcakes, complete with the elegant Italian Meringue Buttercream piped on. To do so, place them gently into an airtight container, ensuring it’s roomy enough to prevent squashing your beautiful piping work. When you’re ready to enjoy them, simply take the frozen clementine squash cupcakes out of the freezer and let them thaw at room temperature for 1 to 2 hours before serving. They will be just as moist and delicious as when they were freshly baked.

Clementine Squash Cupcakes with Maple Italian Meringue Buttercream
Ingredients
For the Clementine Squash Cupcakes
- 3 clementines
- 2 eggs
- ¾ cup brown sugar, packed
- ½ cup light-tasting extra-virgin olive oil, or any other neutral-tasting oil
- 1 tsp pure vanilla extract
- 1 ½ cups all-purpose flour
- 1 tsp baking powder
- ½ tsp ground ginger
- ¼ tsp baking soda
- ¼ tsp kosher salt, or fine sea salt
- 3.5 oz grated butternut squash or pumpkin (about ¾ cup, slightly packed)
For the Maple Italian Meringue Buttercream
- 2 large egg whites, room temperature
- ¼ tsp cream of tartar
- ¼ tsp kosher salt, or fine sea salt
- 2 tbsp granulated maple sugar
- ⅔ cup maple syrup
- 1 cup unsalted butter, room temperature (see note)
To Serve (optional)
- Coarse maple sugar
- Finely grated clementine zest
Instructions
-
For the Clementine Squash Cupcakes: Preheat the oven to 350°F (175°C). Line a mini muffin pan or a regular muffin pan with parchment paper liners.
-
In a medium bowl, zest the 3 clementines (using a Microplane is best.) Juice 2 of the clementines into the same bowl. Peel the third clementine, remove the pith and pits (if any), then finely chop up the flesh and add to the bowl. Add the eggs, oil, and vanilla extract and whisk to combine.
-
In a second, large bowl, whisk the flour, baking powder, ginger, baking soda, and salt together. Pour the liquid ingredients over the dry ingredients and mix just until combined. Fold in the grated squash.
-
Divide the batter between the muffin cups, making sure each cup is only three-quarters full. Bake mini cupcakes for about 15 minutes, and regular cupcakes for about 22 minutes, or until puffed and golden brown. Let the cupcakes cool in the pan for 10 minutes, then take them out of the pan and transfer to a wire rack to cool completely.
-
For the Maple Italian Meringue Buttercream: In the bowl of a stand mixer fitted with the whisk attachment, or in a large mixing bowl, if you’re using a hand mixer, whisk the egg whites with the cream of tartar and salt until soft peaks form. Add the maple sugar a teaspoon (5 ml) at a time, whisking, and when the sugar is all incorporated, keep on whisking until the egg whites are opaque white and stiff peaks form.
-
Pour the maple syrup into a saucepan and bring to a boil over medium heat. Let it boil, without stirring, until a candy thermometer dipped in the middle of the saucepan registers 240°F (115°C), about 5 minutes.
Once the syrup reaches its temperature, immediately remove from the heat and, while whisking the egg whites at medium-high speed, slowly pour the hot syrup in a slow stream along the side of the bowl. Once all the syrup is added, keep on whisking, scraping down the side of the bowl as needed with a rubber spatula, until the meringue is cool to the touch, 6 to 8 minutes.
-
IMPORTANT NOTE: The meringue MUST be cooled to room temperature before adding the butter. Any residual heat will melt the butter and spoil the buttercream.
-
With the mixer at medium speed, add the butter 1 tbsp (15 ml) at a time, making sure each cube is mostly incorporated before adding more. Once all the butter is coarsely mixed in, keep beating until the buttercream is completely smooth and creamy, which could take up to 10 minutes.
-
Frost the Cupcakes: Use an offset spatula to slather a generous amount of buttercream over each cupcake, or use a pastry bag fitted with a round tip or a star tip to pipe the frosting onto the cupcakes. If desired, sprinkle each cupcake with coarse maple sugar, finely grated clementine zest, and/or a tiny slice of clementine.
-
SERVING: Serve the cupcakes at room temperature. If the cupcakes are refrigerated, bring them back out to room temperature at least 1 hour before serving.
-
STORAGE: Refrigerate the frosted cupcakes in an airtight container for up to 3 days. Bring the cupcakes back to room temperature 1 hour before serving to allow the frosting to soften.
You can also freeze the frosted cupcakes for up to 1 month. Thaw frozen cupcakes overnight in the fridge, or at room temperature for 2 hours.
-
NOTE: Italian meringue buttercream is a type of frosting that contains less sugar than your usual butter-based frosting. Italian meringue buttercream has a rich, creamy, silky texture, and the flavor of butter does come through more than in regular birthday cake frostings. For this reason, I recommend using the best quality of butter you can afford. European-style butters and cultured butters produce especially good results. The rule of thumb is: if you enjoy the flavor of a small knob of a particular type of butter on its own, then your buttercream will taste amazing!
