Lemon Curd Cake with Cream Cheese Frosting
This lemon curd cake layers tender lemon cake with silky homemade lemon curd and fluffy cream cheese frosting. It’s a bright, tangy dessert that feels special without fussy techniques.
The cake bakes up soft and buttery, and the curd adds a sharp, refreshing note that keeps each forkful interesting.
Why This Lemon Cake Stands Out
The curd is what makes this cake memorable. It’s buttery, puckery, and slices right through the sweetness of the frosting. You get a little hit of sunshine in every bite.
The cream cheese frosting stays fluffy and tangy, which balances the whole thing so it never feels heavy. Even after a day in the fridge, the cake stays moist and the layers meld together nicely.
Ingredients
For the lemon curd:
- 3 large eggs, at room temperature: they thicken the curd and give it a silky texture
- ¾ cup granulated sugar: sweetens and balances the lemon
- ½ cup fresh lemon juice: strained to remove pulp and seeds
- 1 tbsp lemon zest: adds a fragrant, bright pop
- 4 tbsp unsalted butter, cut into pieces: gives the curd a rich finish
For the cake:
- 1¾ cups all-purpose flour: spooned and leveled, not scooped
- 1½ tsp baking powder: helps the cake rise evenly
- ½ tsp baking soda: reacts with the buttermilk for a tender crumb
- ½ tsp salt: brings the lemon flavor forward
- ½ cup unsalted butter, softened: at room temperature so it creams smoothly
- 1 cup granulated sugar: keeps the cake light and sweet
- 2 large eggs, at room temperature: they emulsify the batter
- 2 tbsp lemon zest: offsets the richness with fresh citrus
- 1 tsp vanilla extract: rounds out the lemon
- ½ cup buttermilk, at room temperature: makes the crumb soft and fine
- ¼ cup vegetable oil: adds moisture so the cake stays tender
For the frosting:
- 8 oz cream cheese, softened: full-fat brick style, not spreadable tub
- ½ cup unsalted butter, softened: gives the frosting structure
- 2½ cups powdered sugar: sifted to avoid lumps
- 1 tsp vanilla extract: for a warm background note
- 1 tsp lemon zest: optional, but it brightens the frosting
Variations / Substitutions
- Swap the citrus: lime curd and zest work just as well, and passionfruit curd gives a tropical twist.
- Use store-bought curd: a 12 oz jar of good quality lemon curd saves time and still tastes bright.
- Make it dairy-free: use vegan butter, vegan cream cheese, and replace buttermilk with ½ cup oat milk mixed with 1 tsp lemon juice. The curd will need coconut oil instead of butter.
- Change the frosting: whipped cream or a simple lemon glaze are lighter options that let the curd shine.

How to Make Lemon Curd Cake
Step 1: Cook the Lemon Curd
Whisk the 3 eggs, ¾ cup sugar, ½ cup lemon juice, and 1 tbsp lemon zest together in a small saucepan. Drop in the 4 tbsp butter pieces and set the pan over medium heat. Stir constantly with a silicone spatula, scraping the corners, until the curd thickens enough to coat the back of a spoon, about 5 to 7 minutes.
The curd will look glossy and feel heavier on the spatula. It won’t be fully pudding-like yet.
Don’t crank the heat or walk away. The eggs can scramble if the temperature spikes, so keep the motion steady. Strain it through a fine mesh sieve into a bowl to catch any cooked bits, press plastic wrap directly on the surface, and chill completely.
Step 2: Mix the Cake Batter
Preheat your oven to 350°F (175°C). Grease two 8-inch round cake pans and line the bottoms with parchment paper. In a medium bowl, whisk the 1¾ cups flour, 1½ tsp baking powder, ½ tsp baking soda, and ½ tsp salt together. In a large bowl, beat the ½ cup softened butter and 1 cup sugar on medium speed until light and fluffy, about 3 minutes. Beat in the 2 eggs, one at a time, then mix in the 2 tbsp lemon zest and 1 tsp vanilla. With the mixer on low, add the dry ingredients in three additions alternating with the ½ cup buttermilk and ¼ cup oil, beginning and ending with the flour. Stop mixing as soon as the last streaks of flour disappear.
The batter will be thick, smooth, and pale yellow.
Overmixing at this stage can make the cake dense. A few small streaks of flour are fine, they’ll blend when you spread the batter in the pans.
Step 3: Bake the Layers
Divide the batter evenly between the prepared pans and smooth the tops. Bake for 25 to 30 minutes, until the cakes are golden and a toothpick inserted in the center comes out clean. Let the cakes cool in the pans on a wire rack for 10 minutes, then run a knife around the edges and invert them onto the rack to cool completely.
The tops should spring back when lightly pressed and the edges will pull slightly from the pan sides.
Don’t rush the cooling. If the layers are even a little warm, the curd will melt and slide off when you assemble the cake. Speed it up by placing the rack in the fridge after 20 minutes.
Step 4: Whip the Frosting
In a clean bowl, beat the 8 oz cream cheese and ½ cup butter together on medium speed until completely smooth and no lumps remain, about 2 minutes. Scrape the bowl, then add the 2½ cups powdered sugar in two batches, mixing on low until combined. Add the 1 tsp vanilla and 1 tsp lemon zest, then increase the speed to medium-high and beat until fluffy, about 2 more minutes.
The frosting should hold soft peaks and spread easily without being runny.
If it feels too soft, pop the bowl in the fridge for 10 to 15 minutes before assembling the cake.
Step 5: Fill and Stack the Layers
Place one cooled cake layer on a serving plate or cake stand. Spoon the chilled lemon curd onto the center and spread it outward, leaving about a ½-inch border so it doesn’t ooze over the sides. Set the second layer on top, flat side up. Spread a thin layer of frosting all over the top and sides to create a crumb coat, then chill the cake for 20 minutes.
This quick chill sets the curd and traps any loose crumbs so your final frosting layer goes on clean.
The cake will hold together better and the curd won’t squish out when you slice later.
Step 6: Frost and Swirl on Curd
Pile the remaining frosting onto the chilled cake and spread it evenly over the top and sides with an offset spatula. For the finishing touch, spoon 2 to 3 tablespoons of lemon curd onto the center of the top and gently swirl it with a toothpick or the tip of a knife. Scatter a little fresh lemon zest over the swirls, then slice and serve.
The curd ribbon looks pretty against the white frosting and hints at what’s inside. If you’re serving right away, the cake slices cleanly at room temperature. Chilled, the layers will be firmer but just as good.
Tips for a Better Lemon Curd Cake
- Give the curd enough time to chill. Warm curd will soak into the cake instead of sitting in a neat layer, so plan to make it at least 2 hours ahead.
- Use fresh lemon juice, not bottled. The flavor is sharper and brighter without any metallic aftertaste.
- Weigh or spoon your flour into the measuring cup. Scooping directly can add too much and dry out the cake.
- Chill the frosted cake for at least 2 hours before slicing for the cleanest cuts. The curd and frosting set up and the layers hold together beautifully.
Bake times by pan size:
| Pan size | Bake time |
|---|---|
| 2 x 8-inch rounds | 25 to 30 minutes |
| 2 x 9-inch rounds | 20 to 25 minutes |
Storing Leftovers
Cover leftover cake and refrigerate for up to 5 days. The frosting firms up when cold, so let slices sit at room temperature for 15 to 20 minutes before eating. You can freeze unfrosted cake layers wrapped tightly in plastic for up to 3 months. Thaw overnight in the fridge, then fill and frost.
What to Serve with Lemon Curd Cake
Fresh raspberries or blueberries tuck nicely next to each slice, and their gentle sweetness plays off the lemon tang. A cloud of unsweetened whipped cream adds richness without extra sugar. For a warm drink, chamomile or Earl Grey tea softens the whole dessert and feels right for an afternoon treat.
Frequently Asked Questions
Can I use store-bought lemon curd?
Yes, a 12 oz jar of good quality curd works well. Taste it first, and if it’s very sweet, you can whisk in a little extra lemon juice.
Can I make this cake a day ahead?
Absolutely. Bake the layers, wrap them, and keep at room temperature. Make the curd and frosting a day ahead and store them in the fridge. Assemble the cake a few hours before serving.
What if my curd didn’t thicken?
It likely needed more time on the heat. Pour it back into the saucepan and cook over medium-low heat, whisking constantly, until it coats the back of a spoon. Don’t let it boil hard.
Can I freeze the whole assembled cake?
Yes. Wrap the fully frosted cake in a double layer of plastic and freeze for up to 2 months. Thaw overnight in the fridge and bring to room temperature before slicing.
Can I use a different frosting?
Swiss meringue buttercream or a simple lemon glaze both work. A glaze will give a thinner, more tart finish, and the buttercream will be lighter and silkier.
