My Limequat Cupcakes with Whipped Cream is an oldie but goodie. I experimented one winter when citrus was in season, and this was one of my favorite recipes using limequats. The limequat syrup is Liquid Gold! I use it mixed into club soda for a refreshing drink and I used it to make a limequat margarita and a great Limequat Vodka Martini too.

Testimonial

“If you love citrus, you are going to love this cupcake. It is light and airy and really good.” – Patti L

Why This Recipe Works

This recipe transforms the unique limequat into a show-stopping dessert through a simple but effective technique. By candying the limequats overnight, you create both a concentrated citrus syrup and delicate garnishes that infuse the cupcakes with layers of flavor. The cupcakes get citrus three ways—through the syrup mixed into the batter, the juice for brightness, and a final brush of syrup after baking that keeps them moist. The whipped cream topping is lighter and less cloying than buttercream, allowing the delicate limequat flavor to shine through rather than being overshadowed by heavy frosting. The make-ahead nature of the candied limequats also means the hardest part is done in advance, making assembly day simple and stress-free.

Ingredients in Limequat Cupcakes with Whipped Cream

Limequats – Small citrus fruits that are a hybrid between kumquats and limes, offering both sweet peel and tart juice that infuse the cupcakes with bright, complex citrus flavor.

Water – Used to create the syrup base for candying the limequats.

Sugar (Granulated) – Sweetens both the candied limequats and the cupcake batter, while helping to create a tender crumb.

Salt – Enhances flavors and balances the sweetness in both the syrup and the cupcakes.

Butter – Provides richness, moisture, and a tender texture to the cupcakes when creamed with sugar.

Limequat Syrup – The flavorful liquid from the candied limequats that adds moisture and intense citrus flavor throughout the cupcakes.

Limequat Juice – Fresh-squeezed juice that amplifies the citrus brightness in the batter.

Eggs – Bind the ingredients together and provide structure and richness to the cupcakes.

All-Purpose Flour (Unbleached) – Forms the structure of the cupcakes and creates a light, tender crumb.

Baking Powder – Leavening agent that helps the cupcakes rise and become fluffy.

Milk (2 Percent) – Adds moisture and helps create a smooth batter when alternated with the dry ingredients.

Heavy Whipping Cream – Whipped into a light, airy topping that’s less sweet and heavy than traditional frosting.

Confectioners Sugar – Sweetens and stabilizes the whipped cream topping.

Ingredient Substitutions

Sugar (in cupcakes) – Substitute with an equal amount of monk fruit sweetener (use a 1:1 baking blend), erythritol, or allulose. For the candied limequats, granulated sweeteners like monk fruit or allulose work best to create the syrup.

Sugar (in candied limequats) – Use monk fruit sweetener or allulose in equal amounts. Note that some sugar substitutes may produce a thinner syrup, so you may need to simmer it longer to achieve the right consistency.

Butter – Replace with an equal amount of coconut oil for a dairy-free option, or use a plant-based butter substitute. For a lighter option, you can use half butter and half unsweetened applesauce, though this will change the texture slightly.

2% Milk – Substitute with skim milk, 1% milk, almond milk, oat milk, or any other milk alternative. For richer cupcakes, you can use whole milk or even buttermilk (which will add a slight tang).

All-Purpose Flour – Use a 1:1 gluten-free flour blend for gluten-free cupcakes, or substitute with whole wheat pastry flour for added fiber (this will make the cupcakes slightly denser).

Heavy Whipping Cream – For a lighter topping, use a dairy-free whipped topping or coconut cream (chilled overnight and whipped). Greek yogurt mixed with a little honey or sweetener can also work as a tangy alternative, though it won’t be as fluffy.

Confectioners Sugar (in whipped cream) – Replace with powdered erythritol, powdered monk fruit sweetener, or powdered allulose. I’m a big fan of Lakanto Powdered Monk Fruit Sweetener. You can also make your own by blending granulated sweetener in a high-speed blender until powdery.

Eggs – For each egg, substitute with 1/4 cup unsweetened applesauce, 1 “flax egg” (1 tablespoon ground flaxseed mixed with 3 tablespoons water, let sit 5 minutes), or a commercial egg replacer following package directions.

Limequats – If you can’t find limequats, substitute with kumquats, key limes, or regular limes. You may need to adjust the amount of juice and syrup to taste, as regular limes are more tart and lack the sweet peel of limequats.

How to make limequat cupcakes with whipped cream

You’ll need to make the candied limequats and syrup the day before baking your cupcakes. So plan in advance.
To get started with the recipe, bring water, sugar and salt to a boil, stirring to dissolve sugar. Slice limequats very thin removing the seeds along the way (the seeds will make the syrup bitter). Add limequat slices to the boiling mixture and remove from heat. Let cool and then refrigerate overnight.

To make the cupcakes, preheat the oven to 350 degrees F. Line a 12-cup muffin pan with paper liners.
Using a hand mixer, cream butter and sugar together until light and fluffy. Be sure to use room temperature butter. Mix butter first until creamy and then begin adding sugar slowly until well mixed and the sugar dissolves into the butter. It should be light and fluffy.

Next, add the limequat syrup and juice. Mix until combined, than add eggs one at a time, mixing well. In another bowl, combine flour, baking powder and salt. Add some the dry mixture alternately with some of the milk into the butter mixture until all the ingredients are well combined.
Scoop the batter into the muffin pan until each cupcake holder is about 3/4 full. Bake for about 20-25 minutes until a toothpick inserted in the middle comes out clean.

Let the muffins cool, then brush the tops of each cupcake with the limequat syrup. Let the cupcakes soak up the syrup.

While the syrup is being absorbed into the muffin, make the whipped cream. Using a hand mixer, whip the heavy cream and confectioners sugar until thick and fluffy.

Top each cupcake with a dollop of whipped cream and top with one candied Limequat slice. (Be sure to let excess syrup fall off first) I’m a huge fan of whipped cream and like it so much better than traditional frosting. If you haven’t had a cupcake with whipped cream, try it. It is just lighter and oh so delish!

Frequently Asked Questions

What are limequats and where can I find them?

Limequats are a citrus hybrid created by crossing key limes with kumquats. They’re small, oval-shaped fruits with thin, edible skin and tart flesh. You can find them at specialty grocery stores, farmers markets, or Asian markets during winter citrus season (December through March). If unavailable, you can order them online from citrus specialty retailers or substitute with kumquats or key limes.

Can I make these cupcakes without making the candied limequats ahead of time?

While the recipe calls for overnight candying, you can reduce this to 4-6 hours if you’re short on time. However, the overnight method allows the limequats to fully absorb the syrup and develop deeper flavor. The syrup also thickens better with longer resting time. For best results, plan ahead and make the candied limequats the day before.

Why do I need to remove the seeds from the limequats?

Limequat seeds contain compounds that make the syrup taste bitter. Removing them ensures your syrup stays sweet and citrusy without any unpleasant flavors. Since the limequats are sliced thin, the seeds are easy to spot and remove with a small knife or your fingers as you slice.

Can I eat the entire limequat, including the peel?

Yes! Unlike regular limes, limequats have sweet, edible peels similar to kumquats. The peel is actually the sweetest part, while the flesh inside is tart. This combination creates a unique sweet-tart flavor when eaten whole or candied. There’s no need to remove the peel before using them in this recipe.

How do I store leftover limequat syrup and what can I use it for?

Store the syrup in an airtight container in the refrigerator for up to 2 weeks. It’s incredibly versatile—mix it with club soda for a refreshing drink, use it in cocktails like margaritas or vodka martinis, drizzle over ice cream or yogurt, add to iced tea or lemonade, use as a glaze for pound cake, or mix into salad dressings for a citrus kick.

Why did my cupcakes turn out dense instead of fluffy?

Dense cupcakes usually result from overmixing the batter, which develops too much gluten. Mix just until the ingredients are combined—you should still see a few small lumps. Also ensure your butter is at room temperature (not melted) and that you cream it with the sugar until light and fluffy, which incorporates air for a lighter texture. Old baking powder can also cause density issues.

Can I freeze these cupcakes?

Yes, but freeze them without the whipped cream topping. Wrap cooled, unfrosted cupcakes individually in plastic wrap, then place in a freezer bag for up to 3 months. Thaw at room temperature, brush with additional limequat syrup if desired, and top with fresh whipped cream before serving. The whipped cream doesn’t freeze well and should always be made fresh.

How long will the whipped cream topping stay fresh?

Fresh whipped cream is best served immediately but will hold for 2-3 hours in the refrigerator. For longer storage, you can stabilize the whipped cream by adding 1 tablespoon of cream cheese or 1 teaspoon of unflavored gelatin (bloomed in water) while whipping. Stabilized whipped cream will stay fluffy for up to 24 hours.

My limequat syrup is too thin. How can I thicken it?

If your syrup hasn’t thickened enough after refrigeration, pour it into a saucepan (without the candied limequat slices) and simmer over medium heat for 5-10 minutes until it reduces and thickens. Let it cool before using. The syrup will also thicken slightly as it cools in the refrigerator due to the natural pectin in the limequat peels.

Can I make these cupcakes with regular limes instead of limequats?

Yes, but the flavor profile will be different. Regular limes are much more tart and their peels are bitter, so you’ll need to zest them instead of slicing them whole. Use 2 tablespoons of lime zest and 1/4 cup lime juice in the batter. For garnish, make candied lime wheels by slicing limes very thin and simmering them in the sugar syrup for 15-20 minutes until translucent.

What’s the difference between limequats and kumquats?

Limequats are more tart than kumquats due to their lime parentage, while kumquats are sweeter and less acidic. Limequats are typically oval or oblong in shape, whereas kumquats are rounder. Both have edible sweet peels and can be used interchangeably in most recipes, though limequats provide a more complex citrus flavor with their lime notes. Learn more about limequats, mandarinquats and kumquats in my discovery post.

Why brush the cupcakes with syrup after baking?

Brushing the warm cupcakes with limequat syrup creates a “soaking” effect that infuses them with extra moisture and intense citrus flavor. This technique, borrowed from Middle Eastern and Mediterranean baking, ensures the cupcakes stay moist for days and creates layers of flavor—the baked-in citrus plus the fresh, bright syrup on top.

Can I use this recipe to make a layer cake instead of cupcakes?

Absolutely! Use two 8-inch or 9-inch round cake pans greased and lined with parchment paper. Divide the batter evenly between the pans and bake at 350°F for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Brush each layer with syrup, then stack with whipped cream between the layers and on top.

Are limequats the same as key limes?

No, though they’re related. Key limes are a true lime variety (Citrus aurantifolia), while limequats are a hybrid cross between key limes and kumquats. Limequats have sweeter, edible peels and are smaller than key limes. Key limes have inedible bitter peels and are used primarily for their juice.

How do I know when my cupcakes are perfectly baked?

Look for three signs: the tops should spring back when gently pressed, the edges should just start pulling away from the cupcake liners, and a toothpick inserted in the center should come out clean or with just a few moist crumbs (not wet batter). The cupcakes should be golden on top but not brown.

Can I make the whipped cream topping ahead of time?

Fresh whipped cream is always best made just before serving. However, if you need to make it ahead, stabilize it with 1 tablespoon of instant vanilla pudding mix or 1 teaspoon of unflavored gelatin (dissolved in 1 tablespoon of warm water and cooled) added while whipping. This will keep it stable in the refrigerator for up to 24 hours.

What makes these cupcakes different from regular citrus cupcakes?

The candied limequat process creates a dual-purpose ingredient—both a concentrated syrup and edible garnishes. The syrup goes into the batter, gets brushed on after baking, and the candied slices top each cupcake. This creates three distinct moments of citrus flavor. Plus, limequats offer a unique sweet-tart complexity that you can’t get from lemons or regular limes alone.

My whipped cream deflated. What went wrong?

Whipped cream can deflate if it’s overwhipped (which causes it to separate and become grainy), if the cream wasn’t cold enough, or if it sat too long without stabilization. Always chill your bowl and beaters for 15 minutes before whipping, use very cold heavy cream (at least 36% fat), and stop whipping as soon as stiff peaks form. Don’t continue beating after peaks form.

How many limequats do I need for this recipe?

You’ll need approximately 8-10 large limequats to make the candied limequats and syrup, which yields enough for the recipe plus extra syrup for other uses. This will give you about 1/4 cup of syrup for the batter, 2 tablespoons for brushing, and 12 candied slices for garnish, plus leftover syrup for drinks or other desserts.
