Lemon Curd Filled Vanilla Cupcakes with Swiss Meringue Frosting

I made these for the girls’ childcare teachers in celebration of teachers’ day this year. I loved how the buttery curdy goodness and sourness cuts through the sweetness of the moist vanilla cupcake. The fluffy meringue frosting was light and fluffy, which complimented the whole cupcake experience.

The cupcake recipe used was the same as the Salted caramel filled vanilla cuppies that I made for my nieces’ birthday. Lemon curd recipe can be found HERE so I will not be repeating the recipe on this post. The swiss meringue frosting is the same frosting used for my Nutella Filled S’mores Cupcakes, and I will be reusing the pictures for this post.

Here is a cross-section of the cupcake. I used an apple corer to remove some part of the cupcake so I can fill it with lemon curd. Alternatively, you can fill it up with a filling nozzle. Here was how the cupcake was made. 🙂

Meringue Frosting

Enough to frost 18 cupcakes


  • 3 egg whites
  • 3/4 cup sugar
  • 1 tsp vanilla extract
  • pinch of salt
  • 12 pieces of candied flower deco optional


  • In a large mixing bowl, whisk your egg whites and sugar together.
  • Heat bowl over a double boiler (pan with little water simmering over low heat).
  • Note that your bottom of the bowl should not touch the water!
  • Whisk constantly while heating the egg whites, we do not want it to be scrambled.
  • Continue whisking until thermometer reads 160F or 70C.
  • If you do not have a candy thermometer or instant read thermometer, the mixture should be smooth, meaning all sugar dissolved and hot to the touch.
  • At this point, remove from heat and bring to stand mixer. Whisk on high until meringue is glossy, formed stiff peaks about 7 mins.
  • Then add salt and vanilla extract, whisk to combined.
  • Frost immediately. As frosting cools further it becomes harder to pipe.
  • Lightly toast frosting with a torch, open stove flame, or broiler.
  • Top with a piece of candied flower deco.

    Hi, is the cupcake itself very sweet? It has no butter content, does it have a nice fragrance?

      Hi, cupcake sugar has been reduced. So no, not very sweet. You can always substitute melted butter for the oil in the recipe if you prefer to use butter.

    If butter is used, will it still give the moist and fluffy texture like oil?

    Hi Sharon. Have you ever tried making the cupcake recipe into a layer cake? Can it hold the weight of other toppings in between the layers, e.g. Fruits? I am thinking of whether to use your purple ombré cake recipe or this one. Want something not too rich, but able to withstand the weight of ingredients. Thanks a lot!

      Hi Louise, I’ve used this to make a layer cake before and it works well. Frosted with SMBC and topped with quite a few cake toppers. I personally prefer this as I find it lighter in texture.

    If you don’t mind me asking, which cake flour did you use. I find that the brand of cake flour determines the result of the cupcake. I use Presto and my cupcakes did not come out looking like yours.
