How to Make Them: A Step-by-Step Visual Guide
1
Craft the creamy lemon curd filling. While store-bought is an option, making it yourself unlocks that true bakery-quality flavor. It’s surprisingly easy and requires only about 20 minutes of active prep time for a deeply flavorful result!
2
Incorporate butter into the dry ingredients. This reverse creaming method is a secret weapon for achieving an incredibly soft and fluffy cupcake texture! Simply mix the room temperature butter into the flour and other dry ingredients until the mixture resembles coarse, sandy crumbs.
3
Gently mix in the wet ingredients. To maintain that delicate texture and prevent overmixing (which can lead to tough cupcakes by developing too much gluten), mix until the ingredients are just combined. A few seconds more after scraping down the sides of the bowl is usually perfect.
4
Bake the lemon cupcakes to golden perfection. Carefully scoop the prepared batter into a lined metal cupcake pan. Each liner should be filled approximately three-quarters full to ensure beautiful domed tops and proper baking.
It’s clear you appreciate the refreshing taste of lemon! For a delightful lemon-fruit combination, you absolutely have to try my soft and fluffy lemon raspberry cookies. They’re the perfect next bake!
5
Whip up the luscious cream cheese frosting. This frosting is incredibly rich, wonderfully creamy, and perfectly tangy. It’s so good, in fact, that it’s the very same frosting I use on my equally delicious lemon poppy seed layer cake!
6
Fill the cooled cupcakes with the lemon curd. My favorite ingenious tool for effortlessly coring the center of cupcakes is an apple corer – it makes the job quick and tidy! Alternatively, a small sharp knife will work just as well.
7
Pipe the decadent cream cheese frosting around the tops of the cupcakes. For that classic bakery swirl, I highly recommend using a star piping tip! It creates beautiful ridges and holds the lemon curd center perfectly.
8
Complete the masterpiece with more lemon curd and fresh garnishes. Fill the exposed centers of the frosting swirls with an extra dollop of lemon curd. For a truly elegant finish, garnish with delicate fresh lemon slices, a sprinkle of bright lemon zest, and a few extra poppy seeds for visual appeal and added crunch!
Expert Tips for Perfect Lemon Poppy Seed Cupcakes
- Room Temperature Ingredients are Key: For a smooth, emulsified batter and fluffy cupcakes, ensure your butter, eggs, milk, and sour cream are all at room temperature. This allows them to combine properly and trap air.
- Don’t Overmix the Batter: After adding the wet ingredients to the dry, mix only until just combined. Overmixing develops gluten, which can lead to tough cupcakes. A few lumps are fine!
- Measure Flour Accurately: For the best results, use a kitchen scale to measure your flour. If you don’t have one, use the “spoon and level” method: spoon flour into your measuring cup until it overflows, then level it off with a straight edge. Never scoop directly from the bag.
- Don’t Overfill Cupcake Liners: Filling liners about 3/4 full is ideal. This prevents overflow and ensures a nice domed top.
- Cool Completely Before Frosting and Filling: Warm cupcakes will melt your frosting and cause the lemon curd to run. Be patient and let them cool completely on a wire rack.
- Chill the Lemon Curd: A well-chilled lemon curd will be thick and easier to work with when filling the cupcakes.
Variations & Customizations
While this recipe is perfect as is, feel free to get creative with these delicious variations:
- Berry Blast: Fold in 1/2 cup of fresh blueberries or raspberries into the cupcake batter just before baking for a fruity twist.
- Almond Extract Boost: Add 1/2 teaspoon of almond extract to the cupcake batter or frosting for a subtle nutty note that pairs wonderfully with lemon.
- Gluten-Free Option: Experiment with a 1:1 gluten-free baking flour blend, ensuring it contains xanthan gum. Results may vary slightly in texture.
- Different Frosting: If cream cheese isn’t your preference, a classic lemon buttercream or even a simple vanilla buttercream would also be delightful.
- Mini Cupcakes: Adjust baking time for smaller cupcakes, typically 10-15 minutes, if using a mini cupcake pan.
Serving Suggestions
These lemon poppy seed cupcakes are a showstopper on their own, but here are a few ideas to make them even more special:
- Coffee or Tea Pairing: Serve alongside a hot cup of coffee, a delicate Earl Grey tea, or a refreshing iced tea.
- Dessert Platter: Arrange them on a beautiful platter with other seasonal treats, fresh berries, or a scoop of vanilla bean ice cream.
- Holiday Spreads: They are perfect for spring holidays like Easter and Mother’s Day, bringing a burst of freshness to your dessert table.
- Garnish Galore: Beyond lemon zest and poppy seeds, consider adding candied lemon slices or a sprig of fresh mint for an extra touch of elegance.
Frequently Asked Questions (FAQs)
- Can I use all-purpose flour instead of cake flour?
- Yes, you can! For every cup of cake flour, use 3/4 cup all-purpose flour plus 2 tablespoons cornstarch. Sift them together thoroughly before using. Cake flour yields a lighter, more tender crumb, but all-purpose will still give good results.
- How long do these cupcakes last?
- Stored in an airtight container in the refrigerator, these cupcakes will stay fresh for 3-4 days. It’s best to let them come to room temperature for about 20-30 minutes before serving for the best flavor and texture.
- Can I freeze these cupcakes?
- Yes! You can freeze the unfrosted, un-filled cupcakes for up to 2-3 months. Wrap them tightly in plastic wrap and then in foil. Thaw them in the refrigerator overnight before coring, filling, and frosting. The lemon curd can also be frozen for up to 1 month.
- Why is my lemon curd not thickening?
- Ensure you’re cooking it to the correct temperature (170°F/78°C) and stirring constantly. It thickens as it cools, so don’t worry if it seems a bit thin when hot. If it’s still too thin after chilling, you might need to gently reheat it to a higher temperature or whisk in a tiny bit more cornstarch slurry (cornstarch mixed with a little cold water) and bring it back to a gentle simmer.
You already know how incredibly soft and moist this lemon cake base is. So, imagine that same tender cupcake, but this time crowned with a dramatic swirl of perfectly toasted meringue. My lemon meringue pie cupcakes are absolutely ideal when you’re looking for something a touch more fancy and show-stopping!

Lemon Cupcake Batter
- 3/4 cup + 2 tablespoons granulated sugar
- 2 teaspoons fresh lemon zest
- 1 1/2 cups cake flour, *See notes below for measuring*
- 2 teaspoons baking powder
- 1 tablespoon poppy seeds
- 1/2 teaspoon fine sea salt
- 6 tablespoons cubed unsalted butter, room temperature
- 1/2 cup whole milk, room temperature
- 2 eggs, room temperature
- 1/3 cup vegetable oil
- 1/4 cup sour cream, room temperature
- 1 teaspoon fresh lemon juice
Cream Cheese Frosting
- 12 tablespoons unsalted butter, room temperature
- 6 oz full-fat cream cheese, cold
- 2 cups powdered sugar
- 2 tablespoons heavy cream
- 1 teaspoon vanilla bean paste or extract
Instructions
For the Lemon Curd
-
Begin by rubbing the fresh lemon zest into the granulated sugar with your fingers until the mixture is fragrant and resembles wet sand. Transfer this aromatic sugar to a ceramic or non-metal pot (to prevent metallic taste from reacting with lemon acid) and whisk in the eggs until thoroughly combined.1/2 cup (100 g) granulated sugar, 1 tablespoon fresh lemon zest, 2 (100 g) whole large eggs
-
Next, whisk in the fresh lemon juice and a pinch of fine sea salt. Place the pot over medium-low heat and cook, stirring constantly with a whisk or rubber spatula. Continue cooking until the lemon curd reaches a temperature of 170°F (78°C), develops a vibrant yellow hue, and is thick enough to coat the back of a spoon. This process usually takes about 8-10 minutes.1/2 cup (113 g) fresh lemon juice, Pinch fine sea salt
-
Immediately pour the cooked curd through a fine-mesh strainer into a clean bowl to remove any cooked egg bits or zest. While still warm, stir in the cold, cubed unsalted butter and vanilla extract until they are fully melted and combined, creating a smooth, glossy curd. Cover the surface of the curd directly with plastic wrap to prevent a skin from forming, and chill in the refrigerator until it is firm and ready to use.6 tablespoons (84) unsalted butter, 1 teaspoon vanilla extract
For the Cupcake Batter
-
Preheat your oven to 350°F (180°C). Prepare a metal cupcake pan by lining it with 12 paper cupcake liners, then set it aside.
-
In a small bowl, rub the fresh lemon zest into the granulated sugar with your fingertips. This technique, called “zesting into sugar,” helps release the aromatic oils from the zest, infusing the sugar with intense lemon flavor.3/4 cup + 2 tablespoons (180 g) granulated sugar, 2 teaspoons fresh lemon zest
-
In the bowl of a stand mixer fitted with the paddle attachment, or using a large bowl and a hand mixer, whisk together the cake flour, lemon-infused sugar, baking powder, poppy seeds, and fine sea salt until well combined. Add the cubed, room-temperature unsalted butter to the dry ingredients and mix on low speed for about 2-3 minutes, until the mixture resembles coarse sand or small crumbs. This is our reverse creaming method for a tender crumb.1 1/2 cups (180 g) cake flour, 2 teaspoons baking powder, 1 tablespoon poppy seeds, 1/2 teaspoon fine sea salt, 6 tablespoons (84 g) cubed unsalted butter
-
In a separate medium bowl, whisk together the whole milk, eggs, vegetable oil, sour cream, and fresh lemon juice until smooth and uniformly combined. Ensure all these ingredients are at room temperature for optimal mixing.1/2 cup (113 g) whole milk, 2 (100 g) eggs, 1/3 cup (65 g) vegetable oil, 1/4 cup (56 g) sour cream, 1 teaspoon fresh lemon juice
-
With the mixer on low speed, gradually add the wet ingredients to the dry butter mixture. Mix until the batter is almost combined, then stop, scrape down the sides and bottom of the bowl with a rubber spatula, and mix for just a few more seconds until everything is fully incorporated and smooth. Avoid overmixing to keep the cupcakes tender.
-
Divide the batter evenly among the 12 cupcake liners, filling each one roughly 3/4 full. You should have just enough batter for precisely 12 perfect cupcakes. For consistent sizing, a cookie scoop works wonderfully here.
-
Bake the cupcakes for 18-25 minutes, or until a wooden skewer inserted into the center comes out clean and the tops spring back lightly when gently touched. Once baked, let them cool in the cupcake pan for 5-10 minutes before carefully transferring them to a wire rack to cool completely. Cooling completely is crucial before filling and frosting!
For the Cream Cheese Frosting
-
In a clean stand mixer bowl with the paddle attachment, or with a hand mixer, cream the room-temperature unsalted butter on medium speed until it is light, fluffy, and creamy, which should take about 1-2 minutes. Reduce the speed to low and add the cold, full-fat cream cheese, mixing just until it’s combined and lump-free. Then, gradually add the powdered sugar, beating at medium-low speed for about 2-3 minutes until the frosting is white, airy, and fluffy.12 tablespoons (169 g) unsalted butter, 6 oz (6 ounces) full-fat cream cheese, 2 cups (240 g) powdered sugar
-
Finally, mix in the heavy cream and vanilla bean paste (or extract) until they are fully incorporated and the frosting is perfectly smooth. Use this glorious frosting immediately for the best texture and piping consistency!2 tablespoons heavy cream, 1 teaspoon vanilla bean paste or extract
Assembly
-
Once the cupcakes are completely cooled, place them back into the cooled cupcake pan—this provides stability and makes coring much easier! Using an apple corer or a small knife, carefully core the center of each cupcake, going about halfway through the cupcake. Transfer the cored cupcakes to a baking sheet or serving platter. Now, fill the hollowed centers generously with the chilled lemon curd. Next, pipe the velvety cream cheese frosting around the lemon curd-filled core, creating a beautiful border or swirl. I love using a star piping tip for an elegant finish! Finally, fill the very center of the frosting swirl with an extra dollop of lemon curd. For an exquisite bakery-style presentation, garnish with thin fresh lemon slices, a sprinkle of bright lemon zest, and a few more poppy seeds. Serve and enjoy!

Notes
Achieve consistent portions with a cookie scoop. For accurate and uniformly sized cupcakes, a large cookie scoop is an invaluable tool to scoop the batter into the liners. It’s not only quicker but also ensures even baking!
Avoid metal pans for lemon curd preparation: When making the lemon curd, always opt for a ceramic or non-metal pot. The high acidity of lemon can react with metal, potentially imparting an unpleasant metallic taste to your delicate curd.
Storage instructions: Any leftover lemon poppy seed cupcakes should be stored in an airtight container in the fridge to maintain freshness. They will keep well for 3-4 days. For optimal taste and texture, allow them to come to room temperature for about 20-30 minutes before serving.
Plan ahead with make-ahead components: You can prepare the luscious lemon curd and the tangy cream cheese frosting up to 5 days in advance and store them separately in the fridge. For an even more convenient baking experience, you can bake the cupcakes in advance, cool them completely, then freeze them (unfilled and unfrosted) for up to 2-3 months. When ready to serve, defrost them in the refrigerator overnight, then proceed with coring, filling, and assembling.
Ingredient Temperatures Matter: For the cupcakes, ensure all dairy and eggs are at room temperature. This helps them emulsify properly with the butter and other ingredients, leading to a smoother batter and a more tender crumb. For the cream cheese frosting, while butter should be at room temperature, using cold full-fat cream cheese helps achieve a firmer, more stable frosting.
