Lemon Poppy Seed Cake with Lemon Curd and White Chocolate

I am so glad to share with you this amazing lemony dessert that I simply adore. This Lemon Poppy Seed Cake with Lemon Curd and White Chocolate Cream Cheese filling is out of this word. It is so flavorful and refreshing and has a great combination of textures. 

The cake consists of a lemon and poppy seed sponge cake at the bottom, with a mousse-like texture white chocolate, poppy seed and cream cheese filling and a homemade lemon curd insert and topping. 

The lemon curd adds a perfect tangy balance to the chocolate filling, which makes it not too sweet, not too tangy and is simply bursting with lemon flavor. It is very light and hardly can stop at only one slice.

Few tips to make the perfect Lemon Poppy Seed Cake

The lemon and poppy seed sponge cake at the bottom is very easy to prepare. It is very soft and flavorful and uses butter, vegetable oil and buttermilk for extra moisture. Really love the texture the poppy seeds bring to the cake as well, so please don’t consider leaving them out.  

If you want a no-bake version of this cake, simply substitute the sponge cake with a cookie crust. Process the cookies with some poppy seeds, lemon zest and butter for an amazing no-bake lemon and poppy seed crust. 

As for the lemon curd which is the star of this cake, I hardly recommend preparing your own lemon curd instead of using the store-bought one. It is very easy to prepare and takes no more than 10 minutes to cook it over bain-marie and have it ready for later. For this lemon curd I have used the whole eggs, so in this way you don’t have to separate the eggs or bother what to do with your whites. 

Each step of the cake is very easy and quick. Hope you will give it a try and don’t forget to tag me on Instagram if you do. Enjoy as we sure did!

    1. Hello from Costa Rica!
      Ella, regarding the Lemon Poppy Seed Cake with Lemon Curd… Can I use mascarpone cheese instead of cream cheese? and Can we use this same recipe using passionfruit instead of lemon?
      I love your recipes!

      1. Ella-HomeCookingAdventure Author says:

        You can definitely use Mascarpone instead of cream cheese. As for the passion fruit.. it might work as well.. though I’ve never tried.

    2. 5 stars
      Awesome recipe… This was my first time trying out a recipe using poppy seeds. Turned out really delicious. My husband loved it…!! Thanks a lot for the recipe…!!

      1. Ella-HomeCookingAdventure Author says:

        So happy to hear that Niv… hope you will try some other recipes too 🙂

    3. looks very nice. Is this able to be freezed?

      1. Ella-HomeCookingAdventure Author says:

        It definitely freezes very well 🙂

    4. Ramona Luffer says:

      Hello from Romania. Instead of poppy seads in the cream can I use chocolate chips? I thought it might taste good with the lemon combination!!
      I really love your recipes!!!

      1. Ella-HomeCookingAdventure Author says:

        Ramona, in mod sigur poti folosi ciocolata in loc de mac. Ti-as recomanda sa cumperi chocolate mini rocks. Merg foarte bine la mousse-uri.

    5. hello from Romania, again 🙂 Ella in primul rand multumesc f.mult ceea ce faci, chiar am facut cateva retete de pe site.
      Am facut si reteta de mai sus intr-o forma dreptunghiulara (20×11) am adaptat ingredientele la forma mea, dar din pacate nu mi-a iesit cum a trebuit, crema si lemon curd au iesit extrem de moi 🙁

      1. Ella Marincus-HomeCookingAdventure Author says:

        Servus Monica. Pt crema de regula imi place sa folosesc Philadelphia, si ti-o recomand in special la deserturile cu crema de branza care nu mai necesita coacere. Ciocolata alba, care aduce si o aroma deosebita ajuta crema de branza sa se intareasca suficient cat sa nu mai fie nevoie de gelatina. Recomand si aici sa folosesti o ciocolata alba pe baza de unt de cacao. Poate de vina a fost lemon curd. Oare ai lasat pe foc suficient cat sa se ingroase? Astept raspunsul tau.

    6. Hi,what are the proportion for making an unbaked cookie base? How much before can cake be assembled.?Thanks

      1. Ella - Home Cooking Adventure Author says:

        You can make a cookie crust. Use 7 oz (200g) cookies with 1/3 cup (80g) butter and 2 tbsp sugar. You can assemble it with even 2 days in advance. Hope you will try it out 🙂
