Lemon Sunshine Cake

Lemon Sunshine Cake

Hello Everyone! Yes I am fully aware that it’s Thursday today, which means I’m a day late from my normal upload schedule of every Wednesday night (Philippine time). There’s a reason for this, because:


For my new followers and friends who don’t know the story behind my blog, before I got it up and running, I already had an interest in cooking. I was already sharing photos of my kitchen adventures on Facebook throughout my first year in university up until my third year. Throughout these years, I kept getting comments and messages from family and friends, encouraging me to start up a blog and share my recipes online.

Finally, after many years of encouragement and pure procrastination, I started what was formerly known as Kitchen Headquarters back in April 16 of 2014. It happened when I was 2 months into my last year of university and in the middle of my mid-semester Easter break; not wanting to tackle the many assignments I had on my to-do list before resuming classes.

To celebrate today’s occasion, I’ve baked a Lemon Sunshine Cake. It strikes the perfect balance between tart and sweet with homemade lemon curd, a moist lemon cake, and a rich, creamy vanilla buttercream frosting. It’s delicious and sure to brighten your day!

Before we dive into tonight’s recipe, please take the time to check out the original recipe that I drew my inspiration from over at The Simple Sweet Life by Claire.

Lemon Sunshine Cake Ingredients



For the lemon curd

  • 60g unsalted butter, cubed
  • 4 free-range egg yolks
  • 1/2 cup white granulated sugar
  • 1/4 cup fresh lemon juice (about 1 large lemon)
  • 1 tbsp lemon zest

For the lemon cake

  • 200g unsalted butter, melted
  • 6 large free-range eggs
  • 3 cups cake flour
  • 1 & 1/2 cup white granulated sugar
  • 1 cup soy milk
  • 6 tbsp fresh lemon juice
  • 2 tbsp lemon zest
  • 4 tsp baking powder

For the vanilla buttercream frosting

  • 500g unsalted butter (cold), cubed
  • 10 free-range egg whites*
  • 2 cups white granulated sugar
  • 10 tbsp water
  • 1 tsp vanilla extract
  • Yellow food colouring (optional)

* Don’t throw away the egg yolks! You can keep them in the fridge for up to two days while you decide what you can make with them. I made an easy Leche Flan (Crème Caramel) recipe. If you’re feeling a little bit creative and inspired, try turning them into Crispy Fried Leche Flan instead!


  1. Lemon Curd: Whisk together the sugar, lemon juice and zest, and egg yolks in a heat-proof bowl over a pot of boiling water.
  2. Cook the mixture, stirring occasionally, until it thickens. It should almost have the consistency of a pudding. Once the lemon curd has thickened, carefully remove the bowl from the pot of boiling water and allow to cool for about 10 minutes.
  3. Slowly incorporate the cubed butter into the slightly cooled curd mixture. Cover and then allow for the curd to cool completely in the refrigerator before use.
  4. Lemon Cake: Preheat oven to 180C (350F or gas mark 4).
  5. Add the eggs and sugar in a large mixing bowl. Using a handheld electric mixer on high speed, whip them together until light and fluffy.
  6. Add the dry ingredients (flour and baking powder) and mix on low speed until just combined. Repeat with the remaining ingredients.
  7. Evenly distribute the batter into four 8” parchment paper-lined and greased cake pans. Bake for 22 to 25 minutes or until a toothpick inserted in the centre of the cakes come out clean. Remove from the oven and set aside to cool for about 5 to 10 minutes before turning them out onto a wire rack to cool down completely.
  8. Vanilla Buttercream Frosting: In a small saucepan, combine the water and sugar and bring to a boil over high heat, cooking until the sugar becomes clear.
  9. While the syrup cooks, whip the egg whites in a large mixing bowl until stiff peaks form.
  10. With the mixed running on high, slowly pour the sugar syrup into the egg whites and whip until the mixture has cooled down to room temperature.
  11. Turn the mixer speed down to low and slowly incorporate the butter and vanilla extract. Continue beating until the frosting is thick and smooth.
  12. Assembly: If necessary, level your cakes before layering for assembly. Place one cake layer on a cake board and spread a layer of frosting on top.
  13. Using an offset spatula, carve out an indent in the frosting and fill with the lemon curd. Repeat with the second and third layer and then top with the fourth. Coat the outside with a thin crumb coat and allow for the cake to set in the refrigerator for about 15 to 20 minutes to set.
  14. Optional: Equally divide the remaining frosting into three batches. Tint each batch a different shade of yellow.
  15. Cover the cake with the frosting and use an offset spatula or bench scraper to smoothen the frosting and remove any excess. Feel free to get creative in how you’re going to use the colours to decorate and present your cake.I topped the cake with the remaining lemon curd and added a few slices of baked/dehydrated lemon slices for that finishing touch.
  16. Place in the refrigerator to chill before serving. Enjoy!

Here are some helpful tips to note when making this Lemon Sunshine Cake:

  1. Make the lemon curd in advance: You can make the lemon curd a week and store it in the refrigerator if you’re looking to save some time when you come around to making this cake.
  2. Crumb coating: 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.
  3. 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.
  4. 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.

Before I end tonight’s post, I want to thank everyone for all the love and support. Of course all the hard work that goes into Amcarmen’s Kitchen wouldn’t have been possible without my #1 supporter, my Mom. I asked my Mom to teach me how to cook after trying to survive off regular takeaway meals from the nearest shop or my attempts at home-cooked food of very poor quality during my first year away from home.

I have my Mom to thank for the days she had to put up with my very little knowledge in the kitchen, and my inability to choose the best produce when she would bring me along to her trips to the market. Thank you Mama for passing down your knowledge and love for food on to me. I know you’re proudly watching over me.

Lastly, I want to thank a very special someone in my life. Since the day we first started talking to each other, you’ve always been very proud and supportive by sharing my recipes each week. And for that, thank you for encouraging and motivating me to continue doing what I love to do!
