About this lemon cake filling:
While making lemon cake filling yourself may seem daunting, it’s really not difficult at all. You’ll be able to make this custard-like filling in 15 minutes. You won’t need any special equipment and you won’t need to learn any fancy cooking techniques.
Lemon filling is so good, you’ll want to leave a fair amount of it in the pan for the cook’s enjoyment. Hey, I’m talking about you! Don’t deny the urge to sample what the pan has to offer. That’s your bonus.
How do you make lemon filling from scratch?
Lemon cake filling is a one-pan recipe.
The ingredients are basic:
- lemon juice
- egg yolk
You’ll mix the dry ingredients in the pan, blend in the egg yolks, whisk in the water and cook, stirring constantly, until the mixture comes to a boil and thickens. Stir in the butter and lemon juice, adding a bit of lemon zest, too, and you’re done! It’s so easy.
What’s the difference between lemon filling and lemon curd?
Lemon filling or custard is usually thickened with cornstarch and can be cooked in a regular saucepan. Lemon curd is richer, with more egg yolks and lots of butter, no water or cornstarch, and is usually made in a double boiler. They can be used pretty interchangeably.
What flavors of cake go well with lemon cake filling?
Lemon cake filling goes well with white cake, yellow cake, or lemon cake. Try it layered in a trifle with pound cake, angel food cake, or lady fingers.
How to use this lemon filling:
Because this lemon filling recipe is very simple, there aren’t a lot of ways to make it uniquely your own creation. However, there are lots of different ways to use it.
Of course, you can use lemon filling as a filling in a layer cake. Or serve it in a bowl with a dollop of whipped cream as a dessert on its own. Make lemon custard tarts with pre-baked pastry shells or mini phyllo cups. Layer it in a trifle with angel food cake or pound cake, with fresh strawberries. Or make regular cupcakes extra special with a hidden jewel of lemon filling.
Lemon cake filling will keep in the fridge up to a week, tightly covered.
