Curd fillings for cakes and cupcakes are so easy to make and they taste amazing! This luscious lemon curd filling has so much flavor! It all starts with a saucepan and a few simple ingredients.

  • First, combine the sugar, cornstarch and water in a saucepan over medium heat. Stir constantly, until mixture thickens and comes to a boil (3-4 minutes).

  • Next, continue stirring as it boils for one minute more. Remove the pan from the heat.
  • Spoon about a half cup of the hot mixture into a small bowl with egg yolks and stir quickly until combined. Continue stirring, while pouring the egg mixture back into the saucepan. The egg yolks are what give the curd its lovely yellow color.

Let the lemon curd cool, then press plastic wrap onto the surface and refrigerate. The plastic wrap will prevent a skin from forming on the top. The lemon curd will thicken a bit as it cools.

FAQs

  • When using this lemon filling for cupcakes, try injecting the lemon curd into the unfrosted cupcakes with a disposable piping bag!
  • I usually use a tip 12 for this. Simply insert the piping tip into the top of the cupcake and push it about halfway down. Then, give it a little squeeze for a second or two.
  • You can do a practice run on a plate to get an idea of how quickly the lemon curd comes out of the bag and adjust accordingly since you won't be able to see the amount of curd inside of the cupcake until you take a bite of it ;0)
  • Everyone is sure to love this instant boost of lemony goodness! Top off your cupcakes with a swirl of Lemon Cream Cheese Frosting (linked below) for an incredible dessert.
  • When using a soft filling such as lemon curd, mousse fillings, whipped cream fillings, etc. you'll want to first pipe a dam of frosting around the edge of the cake layer (about ¼ inch from the edge). 
  • I usually pipe the dam with a medium sized round piping tip, or you can simply snip the end of the disposable piping bag away to create a medium sized opening. Then, pipe your dam.
  • Next, spread the soft filling within the dam and add the next layer of cake. The dam will prevent the lemon curd or other soft filling from escaping and oozing from the sides of the cake once the next layers are added.
  • If you've ever had this happen to you, you know how difficult it can be to fix! Not only will it mess up the look of your cake, but it can also cause bulging or sliding cake layers. Frosting dams are always worth the extra minute or two of time to make one.

There are so many cakes that pair perfectly with lemon curd! Homemade white cake, white velvet cake, lemon cake, and orange cake are just a few examples!

Our homemade Lemon Coconut Cake is another great example! We often pair our lemon curd cake fillings with homemade whipped cream!

Yes, homemade lemon curd as well as cakes with lemon curd filling should be refrigerated.

While this Lemon Curd recipe is at the top of our list, we also love Lemon Whipped Cream Filling, Lemon Cream Cheese Frosting, and an Easy Lemon Cream filling from our Lemon Cream Cake (which is a pudding-based "mousse")!

  8. Hi Julie, We have never frozen a frosted lemon cake with curd filling, but since lemon curd can be frozen, I think you could do so with no problem. We often fill with a layer of frosting and a thin layer of curd over that. If you want a thicker layer of curd don't spread it close to the edge, leave about 1 inch space around the edge so it will not be pressed out by the weight of the top layer. I would thaw in the refrigerator the day before you plan to serve it.
