This lemon poppy seed cake strikes the perfect balance between tart and sweet! Made with homemade lemon curd, a moist poppy seed cake and a rich, creamy vanilla buttercream frosting, this delicious cake is sure to brighten your day!
Although there were a lot of things about home that I missed while I was living in Norway, one of the thing I missed most was birthdays. Birthdays with family and friends, sharing cake, making cake, eating all the cake…
And so to make up for not being there to make cakes in person, I would often bake cakes in people’s honor, share the recipes on my blog, eat my feelings… You know, the usual things people do when they miss someone.
So for my Mum’s birthday one year, I made this cake. It’s a combination of all of her favorite things: Lemon, poppy seeds and equal parts tart and sweet. I don’t know how she ended up with a daughter whose sweet tooth is as massive as mine because that’s just not her jam (or curd, in this case).
But having made this cake almost 5 years ago, I thought it was time this bad boy got himself an update. Scroll all the way to the bottom if you want to see one of the cringy original photos.
How to make this lemon poppy seed cake
First, if you’re short on time and don’t want to make everything from scratch, you can cut a few corners by using store bought lemon curd and store bought frosting. For this recipe you’ll need about 2.5 lb of frosting and one 10 oz jar of lemon curd.
If you’re not using store bought lemon curd, you’ll want to start by making that. To make the lemon curd, whisk together the sugar, lemon juice and zest, and egg yolks in a bowl over a pot of boiling water.
Once the lemon curd has thickened, remove the bowl from the pot of boiling water and allow to cool for about 10 minutes. Cube the butter and whisk it into the slightly cooled curd mixture. Cover and allow to cool completely in the refrigerator before use.
Second, make the cake. In a bowl, combine the milk and butter for the cake, and microwave using 20 second increments until you can stir the mixture smooth.
In the bowl of a stand mixer, whip the eggs and sugar until light and fluffy. Add the dry ingredients and mix on low until just combined. Repeat with the remaining ingredients.
Pour into three 6″ parchment paper-lined and greased cake pans. Bake at 350F for 22-25 minutes or until a toothpick inserted in the center comes out clean.
Third, make the frosting. In a small saucepan, combine the water and granulated sugar for the frosting over high heat and bring to a boil, cooking until the sugar becomes clear. While the syrup cooks, whip your egg whites until stiff peaks form.
Pour the sugar syrup into the egg whites (with the mixer on high) and whip until cooled to room temperature.
Decrease the mixer to low, add the butter and vanilla extract, and continue beating on high until the frosting is thick and smooth.
Finally, assemble and decorate the cake.
Level your cakes (if necessary) and spread a layer of frosting between each. Use your offset spatula to carve out an indent in the frosting and fill with lemon curd.
Coat the outside with a thin layer (crumb coat) and allow to set up in the refrigerator.
Cover the cake with frosting, using an offset spatula or bench scraper to smooth the frosting and remove any excess. If you’re new to cake decorating and want a more in-depth guide, check out my post on how to smoothly frost a cake.
Tint the remaining frosting a shade or two of yellow. Dab on the yellow frosting on the lower half of the cake and use your offset spatula or bench scraper to smooth it.
In the microwave, heat the candy melts and heavy whipping cream using 10 second increments until it stirs smooth. Pour the ganache into a piping bag and drip down the sides.
Spoon the remaining frosting into a piping bag with a large star tip and pipe a crown of frosting around the top.
Expert tips
- Make the lemon curd in advance: If you’re looking to save some time, you can make the lemon curd a week and store it in the refrigerator.
- Measure your batter: Making even layers of cake start with measuring your batter. For this recipe, that means about roughly 9.3oz of batter per pan (for three pans).
- Chill your cake: Cool cake is easier to cut and handle, so chilling your cake for a short while before use will make this process easier.
- Saving time with store-bought frosting: If you don’t want to make your own frosting for this recipe, you can substitute about 2.5lb (or 2.5 containers) of store-bought frosting.
- Crumb coat: Spreading a thin layer of frosting around the sides and top of the cake, and then refrigerating it will lock in any crumbs and keep them from reaching the surface of your frosted cake.
- The trick for smooth frosting: You’ll need a rotating cake stand and a bench scraper. Place the small end of the bench scraper on the cake stand, long end against the frosting and turn the table. Once excess frosting is removed, heat the scraper in hot water, wipe and drag around the outside of the cake.
- Storage: This cake will keep at room temperature, uncut, for 3-4 days. For best results, cover it with a plastic lid, bowl or place it in a cardboard box.
- Storing cut cake: Once your cake is cut, you’ll want to protect the exposed cake area. The easiest way to do this is with a piece of plastic wrap or two.

Update Notes: This post was originally published in March of 2015 but was republished with step-by-step photos and tips in February of 2019.
Oh yay! You made it all the way to the bottom. High five!
So you probably noticed that this is in updated version of an older recipe from my blog. And maybe that has you wondering what the cake originally looked (or maybe not… I’m no mind reader). Was it pretty? Did she even know how to use a decent camera?? That would be a no and no.
And as much as I hate to share my cringy, old photos, I also appreciate the glimpse at growth it allows and the opportunity to remind you: Seriously guys, if I can do it, ANYONE can. Here’s a little glimpse at the original cake.
This is stunning and you are right, I so want to try it!! All of my favorite flavors in one cake 🙂 (And colors too.) Thank you for the birthday wishes and have a wonderful trip to London!
I’m so glad you like it! I can definitely make it for you when I visit this summer (if Pappo will allow us to use the oven for that long, that is) if you haven’t already made if for yourself. 🙂
Hi Claire,
Is this cake moist? Do you think adding sour cream would make it moist? Lastly, if I attempt to make it for an 8 inch should I just double the recipe?
Hi Stephanie! I think it’s a pretty moist cake as far as white cakes go, but you could definitely add sour cream if you’d like. As far as adapting the recipe for an 8″ cake, doubling it would be slightly more cake than you would need (to perfectly scale it you’d want 1.75x the recipe) so just keep that in mind as you adjust your baking time. 🙂
How much sour cream would you add and would it be a substitute for the milk?
Hi Julie! I usually don’t use sour cream because it makes for a very dense cake. That said you could probably adapt this recipe, which uses sour cream, by halving the recipe and adding 3 tbsp lemon juice, 1 tbsp zest and 1 tsp poppy seeds: https://thesimple-sweetlife.com/peaches-and-cream-sheet-cake/
Oh my goodness, Claire, this is gorgeous! My husband is addicted to lemon desserts and I love a good decorating challenge. Can’t wait to try this.
So glad you liked it! You’ll have to let me know what you think of it if you try out the recipe! 🙂
This cake sounds amazing! I’ve had lemon and poppyseed muffins loads of times – but never in a cake form. Love the idea for baking cakes for friends and family members’ birthdays – even if they’re not here to enjoy them!
Although I’m sure it’s not a novel idea, I haven’t seen many lemon poppy seed cakes that are frosted layer cakes and aren’t loaves. I figured that needed to change. 😉 But I definitely enjoy making cakes for people, even if they aren’t here to enjoy it- makes me feel like I’m able to celebrate them across the miles. 🙂
That gradient you have looks gorgeous! The flavor combo in this sounds just perfect.
Thank you! I think it turned out almost as good as your ginger beer cupcakes look! 😉
This is so beautiful, and I love that it’s called a sunshine cake! (We sure could use some sunshine in Connecticut right about now!!) I think this might be this year’s Easter cake! 🙂
Since we’re not getting any sunshine here in Norway either, I thought I’d whip up a little in my kitchen. 😉 Wishing you sunnier days!
This cake is too gorgeous for words! I seriously appreciate the step-by-step frosting pictures, too. I haven’t attempted ombre frosting yet but with your tutorial, I just might!
Ombre frosting is so much fun to do and a definite must try if you haven’t done it yet! 🙂 I find it easiest to pipe the frosting on because it helps keep it even and keeps you from mixing the colors as your applying them. I’m so glad you found this tutorial helpful and you’ll have to share some pictures if you try ombre frosting!
Wow your ombre frosting is so impressive! I am done with winter food and ready for lemon cake 😛
Down with winter! Long live lemon cake! 😉
This looks wonderful! It’s so, SO, pretty and looks delicious too. I love your frosting job. This cake makes me excited for spring/summer! 🙂
It has been SO gray here lately. Lots of rain and clouds, and the little display of lemons at the grocery store just kind of looked like a ray of sunshine! But hey, the days are getting longer (and ever so slightly warmer)! 🙂
This looks beautiful, and so delicious!
Thank you! I’m so glad you think so! 🙂
This cake is gorgeous! I love lemon desserts and I wish I had this right now!!
I’m so glad you like it! 🙂
Lemon desserts are one of my favorites, and I LOVE the hombre look of the frosting!
Lemon desserts are pretty tasty, and such a sunny flavor. Thanks for the sweet comment! 🙂
this is such a gorgeous cake! It makes me feel all sunshine-y just looking at it 🙂
Thank you! 🙂 It’s definitely the time of year for sunny cakes!
I love this cake and your tutorial photos make it look so easy to make! I’m pinning this so I can try my hand at it. Thanks for sharing!
You’ll have to let me know what you think of the recipe if you try it! 🙂

Love this design! Just a quick question, would it work with cream cheese frosting since I know it can be harder to frost with. Thanks!
I’m so glad you like the design! I think this would absolutely work with a cream cheese frosting as long as it’s a firm frosting and not too soft.
Just made this cake today (slightly altered.) The curd was made yesterday exactly as instructed and came out delicious. We didn’t have 6″ pans, so we doubled the recipe and made three 9″ layers. The recipe didn’t call for salt, so we added a pinch of salt to cut down on the sweetness. We had some concerns when we got to the butter cream frosting for two reasons. The first being the amount of frosting the recipe would yield… although we doubled the cake recipe, we kept the measurements of the frosting the same as instructed and still had A LOT left over. The second concern was the overwhelming sweetness to the frosting. We cut that with about 5T of lemon juice, and it made a huge difference. The last bit of altering we did to this cake was toast unsweetened coconut flakes to decorate the tops and sides. Unsweetened coconut is so mild in flavor and looks so pretty once it is toasted.
Overall, very pleased.
I have cake flour – would I just use that in place of the flour and baking powder?
Great question Tracy! The main difference between cake flour and all purpose flour is that cake flour is more finely ground and lower in protein. It does not have a leavening agent in it (like baking powder) so I wouldn’t omit that if I were you. Personally I don’t use cake flour very often so I don’t have a great answer for you in terms of substitutions, but this site recommends using 1 cup + 2 tablespoons of cake flour for every 1 cup of all purpose flour: https://www.thespruce.com/how-to-make-cake-flour-p2-3057755 If you try that, I’d love to know how that works out! 🙂
Oh my goodness!!! I made this today for dinner guests… Letting them cool… The whole condo smells divine!!! I could not wait to comment before tasting it… They look perfect… I did double the recipe, PLUS 3/4 c. flour, for 3 nine inch rounds and it was just about perfect minus a tablespoon or two of batter… They are light and springy in the middle… Nice and golden tops… Texture looks to be moist when turned out on cooking rack… The smell is KILLING me!!!😉😍 If this tastes half as good as it looks and smells??? This could be my new favorite!!! My Grandbabies will live this also!!!!😊😁 Thank you for sharing… Grandma Cami🌻
This is one of my all time favorites! And I love the re-do 🙂 Beautiful and sooo….. tasty!
It’s cold and windy here again today, so this bright and cheery cake is just what I needed to look at! Love anything lemon, especially when it is decorated as lovely as this cake! And your older photo looks delicious too!
