Lemon Baked Custard with Sponge Cake Top is an easy, magical dessert. Baked in individual custard cups, the batter forms two layers; a creamy lemon custard on bottom and light, airy cake on top! Gluten-free and gluten options.
This recipe was originally published in March 2011 and has been updated in April 2018!
Today’s recipe is a reprisal of my ALL TIME favorite childhood dessert: Lemon Custard with Pillow Top (or at least that was the name on my Mom’s recipe card). This simple lemony delight is a recipe my grandmother and mother each have made for as long as I can remember.
I shared the recipe early on Boulder Locavore but the time is right to dust it off to share again!
As a child I thought this recipe was magical. Baked custard in individual cups, this lemony dessert is part custard and part cake. As it bakes the batter separates and forms a rich lemon custard on bottom and light, cakey top layer.
Three Generations of Lemon Baked Custard with Sponge Cake Top Recipe
When I first shared this recipe in 2011, my mother told me she thought the origin of it may have been from The Joy of Cooking. Makes sense.
My grandmother did not develop her own recipes, that I’m aware of, and at the time one jotted down their favorite recipe on a recipe card and stuck it in their recipe box for easy access.
Before starting my redo here, I became curious about this recipe’s lineage and looked it up in The Joy of Cooking. It wasn’t there.
I mentioned it to my husband who is an excellent cook and curator of the hundreds of cookbooks we own. He said that I was looking in a more recent version of The Joy of Cooking (copyright 1997); that the early version, that schooled in everything including how to skin squirrels, was a different version.
He pulled out an earlier version, a 1975 printing of the original copyright 1931 cookbook. Indeed, I found ‘Orange or Lemon Sponge Custard’ which very closely resembles my family recipe. There were modifications, even between my grandmother’s recipe card and my mother’s. And I’ve tweaked it a smidge myself!
Making Lemon Baked Custard with Sponge Cake Top
Having not made the recipe for some time, I did a test run wanting to be sure there was no tweaking needed (there was).
The recipe is an easy one and fascinating, illustrating the magical qualities of baking (chemistry really). A batter is made of softened butter, sugar, salt, egg yolks, lemon juice, lemon zest, flour and milk.
Egg whites are beaten until firm but not dry then folded into the lemony batter making a bumpy, foamy mixture that never hints at the delicious end result forthcoming.
The mixture is spooned into custard cups, baked in a water bath and served hot or chilled. A dollop of freshly whipped cream on top makes it even better.
NOTE: the baked custard will relax as it cools with the puffed top becoming flatter as shown in the photos.
SHORTCUT PREP TIP: I keep a bottle of fresh lemon juice (real lemon juics not from concentrate) in my refridgerator all the time. This saves the time of juicing the lemons and provides the same quality juice!
What is a Water Bath?
A water bath is a manner of cooking by adding containers of ingredients to a larger pan of hot water to be baked in the oven.
The benefits of a water bath is that it adds moisture while cooking to prevent cheesecakes from cracking or custards from becoming rubbery. It also provides even cooking temperatures all through the cooking time.
The water added into the pan is hot so there is no temperature shock to the items being cooked in the water bath.
An Early Version of ‘Magic Cake’
A few years back there was a craze over something called ‘Magic Cake’. Do you remember that? It did not escape my culinary curiosity either.
I made a Blood Orange Magic Cake with Candied Almond Slices version and one for the holidays Eggnog Magic Cake.
While making this the Lemon Bakes Custard it struck me these were the predecessor of Magic Cake; a batter that separates during cooking to make two distinct textures in the finished dessert.
Suggested Supplies for making Baked Lemon Custard Cups
I still have the original Pyrex custard cups my grandmother used to make this recipe. I’ve misplaced a few so just reordered the current version of the custard cups online. They are perfect because you can see the layers and they have a vintage vibe I love. They are affordable and handy for prepping ingredients, holding small items and many more uses.
You’ll need a:
- 6 6-ounce custard cups or ramekins (see link for the ones I used for the recipe above)
- 9-inch by 13-inch baking dish,
- stand mixer (or hand mixer),
- mixing bowl (if not using the bowl of a mixer)

How to Make Lemon Baked Custard with Sponge Cake Top – Step by Step:
Lemon Baked Custard with Sponge Cake Top
These simple to make lemon custard cups with a light, cakey top are refreshing and unique. The custard batter naturally separates during cooking to form a layer of actual lemon custard and a cake. Fresh and light, they are always a welcome treat at the end of a meal!
- 2 tablespoons Unsalted Butter softened (plus extra to butter the ramekins)
- 2/3 cup Granulated Sugar
- 1/8 teaspoon Kosher Salt
- 3 teaspoons Lemon Zest
- 4 large Eggs room temperature, separated
- ¼ cup freshly squeezed Lemon Juice
- 1 cup Whole Milk
- 3 tablespoons All Purpose Flour (gluten-free or regular)
Preheat oven to 325 degrees. Butter 6 6-ounce custard cups or ramekins.
In the bowl of a standing mixer, cream together the softened butter, sugar, salt and lemon zest. Beat in egg yolks.
Slowly pour in lemon juice and milk, alternating with the flour; mix to combine.
In a separate upright mixer bowl or using a hand held mixer, beat the 4 egg whites until firm but not dry.
Fold the egg whites gently into the lemony batter just until combined. NOTE: it will be slightly lumpy.
Evenly spoon gently into the prepared custard cups (do not pour). Place custard cups into a 9-inch by 13-inch (or larger) baking pan. NOTE: they should not be touching each other. Add hot tap water to reach halfway up the side of the custard cups (water bath). TIP: place the baking dish on oven shelf before pouring the hot water in.
Cook until the custards are lightly browned on top and a knife comes out clean; approximately 30-40 minutes. Remove from oven and allow custards to remain in the water bath an additional 5 minutes to set. Transfer to a cooling rack. May be served hot or chilled.
