Magic Custard Cake
When I saw a magic custard cake recipe on Pinterest, I was floored. I mean, it left me in a state of delicious shock that something so simple could create an incredible piece of dessert.
What is Magic Custard Cake?
Magic custard cake it truly a magical piece of cake. This dessert is to not too sweet (which I love the most) and is loaded with a wonderful middle layer that’s soft and custard-like. This cake is soft, pillow-y and melt-in-your-mouth wonderful. The delicate top layer of cake and bottom crust is what holds the custard layer together. It looked so easy and like magic, it separated into three layers. It’s cake layer on top, an egg-flavored custard layer in the middle and another dense custard layer on the bottom.

For two weeks, my obsession grew for this cake and I stalked the internet for what ever info I could find, which wasn’t much. I wanted to call this a Magic Custard Cake Recipe. After a search on Google, I realized that there were many variations of this classic “Magic Custard Pie” already being shared from kitchen to kitchen. I inhaled my first two slices in one sitting. And this is coming from someone who is usually one and done with sweets. (Salty stuff is a whole ‘nother story.)

Magic Custard Cake Recipe
Ingredients
- 1/2 cup (113 g) unsalted Butter (1 stick)
- 2 cups (480 ml) Milk
- 4 Eggs , separated
- 4 drops White Vinegar
- 1 1/4 cups (150 g) Powdered Sugar
- 1 Tablespoon (15 ml) Water
- 1 cup (125 g) Flour
- 1 teaspoon (5 ml) Vanilla Extract
- extra confectioner's sugar for dusting
Equipment
- 8”x8” baking dish
Instructions
- Preheat the oven to 325°F/160°C. Lightly butter or grease a 8"x8" (20x20cm) baking dish.

- Melt the 1/2 cup (113g) butter and set aside to slightly cool slightly.

- Warm the 2 cups (480ml) milk to lukewarm and set aside.

- Whip the 4 egg whites and 4 drops vinegar to stiff peaks. Set aside.

- Beat the 4 egg yolks and 1 1/4 cups (150g) powdered sugar until light.

- Mix in the melted butter and the 1 Tablespoon (15ml) water for about 2 minutes or until evenly incorporated.

- Mix in the 1 cup (125g) flour until evenly incorporated.

- Slowly beat in the warmed milk and 1 teaspoon (5ml) vanilla extract until everything is well mixed.

- Fold in the egg whites, 1/3 at a time. Repeat until all of the egg whites are folded in.

- Pour the batter into the prepared pan.

- Bake at 325°F/160°C for 45-60 minutes or until the cake is barely jiggly in the center. If the top browns too quick before the minimum of 45 minutes, then cover the cake with aluminum foil and cook for remainder of time needed.

- Allow cake to completely cool before cutting and then dust with powdered sugar. For faster cooling you can place the cake in the fridge. Even after fully cooled, it will still be slightly jiggly because it's a custard layer cake.

i love custard pies so would love to try this!
WOWZA! I’ve not ever seen a recipe for the cake! I pinned this. Thanks so much for sharing a link to my blog (via your ‘kitchen’=) to my magic custard pie recipe. I found you when I saw the traffic I was getting. Awesome!
So cool! What a fun recipe!
It’s like our egg pie in the Philippines we pour the batter into a pie crust and we use corn flour or custard flour if available.
Hi,
Okay, I made it and baked it for 55 minutes. Took it out the oven about 40 minutes ago. However, I just checked to see if it’s cool enough to cut, but it’s jiggling….a lot! I know it’s a custardy cake and will have jigglings but it feels like there thick liquid inside. Is that normal or should I let it cool for a few hours before attempting to cut it? Help!
Tien- yes, you should let it cool before you cut it.
So what you’re telling me is to go to bed without having a slice? Umm, it’s gonna be a long night…. 🙂 Oh fine, I’ll be a big girl and wait…
I just took it out of the oven and it was still somewhat jiggly in the middle. Should it be that way? The top was already pretty golden at 1 hour so I took it out. Letting it fully cool before cutting into it for fear of oozing. Will keep you posted on my results tomorrow!
It turned out beautifully. I wasn’t able to turn the cake out from the pan as cleanly, so I left it in the 8×8 glass dish. I got 3 layers and it truly was a delightful dessert. My 6 year old helped me make this and she was so proud of herself! This recipe is a keeper. It reminds me of two Filipino desserts I grew up with (a mochiko rice flour cake and flan in one!). No too sweet, which I love. Thanks Todd and Diane for sharing this!
My Mom used to make this, she called it impossible pie, and if I remember correctly it had some coconut in it that would float to the top and make a crispy crust.
This sounds wonderful and I’m going to attempt it tomorrow while the kids are at school. Does it need to be kept refrigerated after baking? And will it taste as good the second day (if there’s any left)?
Angela- The cake needs to be completely cooled, but to help it cool faster, we placed it in the fridge for a while till it felt like the center settled a bit. Yes, it still tasted wonderful the next day!
Thank you for the answers. I made it this morning and have just cut into it….a perfect three layers! I did use the vinegar for the whites but next time I’ll see if cream of tartar works as well. I love how clean your cuts were so next time I’ll also have to line the pan with parchment so I can remove the whole cake! Thank you for the recipe – it’s absolutely mouth-watering 🙂
I’m coming over for a slice… any left?”-)
This recipe is a perfect homemade version of the old 1970’s standby, Bisquick Impossible Pie! Of course, the original version on the Bisquick box did not call for whipping the egg whites, but aside from that, I’d say it’s a dead ringer! There were numerous variations…coconut, pumpkin, a fruit version that came out very much like clafoutis, etc. There were savory versions too. This recipe is going to be a blast to experiment with…
Absolutely stunning cake!
I JUST saw this on Pinterest too. I am TOTALLY intrigued! And glad to see it worked for someone else…
This post reminded me why I originally subscribed to your newsletter; the photography.
Your photography is so beautiful and makes the custard cake look so elegant and desirable.
Will make this tomorrow. My grandmother made what she called a Peachy Pie that had a custard layer over peaches or apricots and then meringue on top. It was wonderful and this reminds me of that pie.
Oh my! I have to make this tonight.
Wow, I’ve never seen anything like that cake! Looks delicious and pretty simple to make. I’ll be trying it soon!
