A magic cake that everyone loves!
I was going through my posts and realized we haven't talked about chocolate very much lately, right? This recipe is probably one of the few chocolate cake recipes I have on the blog to this day and I want to thank you so much for making this chocolate magic cake and loving it! You all are the best readers in the world and I can't wait to share many more recipes with you!
I've edited this post to add some notes and answers to questions that are being frequently asked about this chocolate magic custard cake. This magic cake is a favorite of ours and what I love mostly about it is that it's not overly sweet and with a little bit of powdered sugar dusted on top, it achieves a perfect balance of sweetness and decadence.
What is chocolate magic custard cake?
This is not the usual chocolate cake with frosting or icing on top. This is an indulgent cake that will wow anyone who tries it! Three layers of deliciousness all coming from one simple batter? That's something to wonder about! Chocolate magic custard cake is made with basic ingredients but it's the technique that makes it magic!
This chocolate magic cake recipe is pretty simple to follow and requires basic ingredients such as eggs, flour, cocoa powder, sugar and butter. The process of making this cake is also very similar to any other cake we've already made.
Chocolate magic cake has three layers: A fudgy layer at the bottom, a chocolate custard layer in the middle and a souffle-like, airy layer on top.
Wait, so what makes this chocolate magic cake special?
It's the ratio and measurements of the ingredients which give this cake a magical texture. This cake only has half a cup all purpose flour and ⅓ cup cocoa powder whereas it requires 2 cups of lukewarm milk which means the batter is going to be very thin. The thinness and the addition of egg whites beaten to stiff peaks make this chocolate magic cake divide into three layers with the top layer being airy, the middle layer having a custrad-y texture and the bottom being fudgy.
How to make chocolate magic cake
First of all, melt the butter and set aside to cool. Then beat the egg whites to reach stiff peak and set that aside as well. Now mix egg yolks, sugar and butter, add in flour and cocoa powder and mix until combined. Add in milk and once everything is mixed, fold in the egg whites gently and don't over mix. Bake the cake in the oven for about on hour until the center is firm but a little jiggly.
The most difficult part is to let the cake cool for some hours in the fridge. But I promise, it's worth the wait!
Now this isn't one of those recipes that are only pretty on the blogs and turn out to be a total disaster when you make it at home. This is a practical recipe that you'll enjoy making every time. However, a little bit of troubleshooting never hurts, right? This magic cake is all about the three layers of deliciousness so we must make sure they're coming out right.
My chocolate magic cake doesn't have all the three layers. Why?
There can be several reasons for that:
- Egg whites: Make sure the egg whites have reached stiff peaks. That means once the beaters are lifted, the egg whites stand straight up. This is the point you should stop beating the egg whites. To reach stiff peaks faster, add a pinch of sugar to the egg whites while beating them. Aged egg whites also reach stiff peaks quicker.
- Oven heat: Ovens are different and each oven gives a different result when it comes to baking. For this magic chocolate cake, you should start checking after 40 minutes of baking. For me, it usually takes between 50 to 60 minutes. The cake is done once it's slightly jiggly in the center but firm in other parts.
- Mixing: Make sure you don't over mix the batter. Over mixing will result in deflated egg whites and that would make the chocolate magic cake lack the clear layers.
As this is not a common cake, there are question that might come up when you decide to make this cake. I have answered a few of the common questions here, but you can comment any other questions you have and I'll add them to this list.
FAQs about making chocolate magic cake:
- Can I double this recipe?
Yes! This cake is made in an 8x8 cake pan. If doubling the recipe, you should use a 9x13 inch pan.
- Do I need to refrigerate this cake?
This cake should cool in room temperature and then be refrigerated for an hour or two before serving. This cake is best eaten on the day its made but if you have leftovers, refrigerate them.
- Can I use any type of milk?
Any type of dairy milk, yes. You can use whole milk, lowfat or non-fat milk that contains dairy. As for non-dairy milk such as almond or coconut milk, I have not tried them myself yet.
- Should I use Dutch processed cocoa powder or regular cocoa powder?
Both would work perfectly in this recipe. But I prefer Dutch processed cocoa powder.
- Can I make chocolate magic cake without eggs?
Unfortunately not to my knowledge. You need the eggs to have that airy, light texture on the top layer and the custard-y texture to the middle layer. So you definitely need the eggs.
- How long should I whip the egg whites?
You should whip the egg whites until they reach stiff peak. You can read more about how to beat egg whites on The Spruce Eats.

Can I use 1/2 . This recipe is intriguing and I want to try it.
I don't recommend halving this recipe.
Used erythritol for the sugar and gluten-free flour. It tasted almost like a brownie but looked nothing like the picture.
Hi Nancy, since you've changed the key ingredients in the recipe, that could be the reason the texture and look is different from the original recipe.
One question about your Magic Cake recipes I never saw answered is can I substitute a good quality oil e.g. Avocado or Organic Canola oil instead of using melted butter? I prefer not to use Coconut oil. Your recipes look amazing. Thanks!
Hi Deena, Thank you for your comment. I'm not sure about using oil instead of butter in this particular recipe. I'll test it and if it works out, will post it here!
Wow! This recipe checks all my chocolate boxes: fudgy, custardy, and souffley! Delish!
Looks so good! Can't wait to try this one with my family.
Made this last night and it turned out extremely well! Very chocolaty and satisfyingly good. My husband loved it too! We usually make the original version and we liked this one better.
Hi Kristen! Thank you for your comment. I like the chocolate version better as well, the three layers are so fun and tasty! Enjoy!
I noticed you wrote 1 stick of butter, but stick sizes vary pretty wildly in my local grocery. A lot of the magic cake recipes call for 1/2 cup of melted butter, so what size stick are you using? For reference the ones I have available are the super thick natrel ones with the purple packaging. Should I just go ahead and measure out a 1/2 cup of melted butter or is your amount maybe closer to a cup?
Hi Cynthia, one stick of butter equals to 4 ounces which is 113 grams 🙂
It is 1/2 a cup
This recipe was so easy that my 4 year old helped me make it & it was delish!! I was scared it might be too sugary so I cut back on the sugar but it wasn't overly sweet at all. Will definitely make again! Thx!
Hi Rachel! I loved your comment! I'm so happy you liked it and your cute 4 year old has some good talent! <3 <3
I have been trying to remember how we made this Tunnel of Fudge cake for a long time, so I am extremely happy to see this recipe!
So glad to hear that! This cake is so good!
This looks amazing. I'm going to try to make it with a 1-to-1 gluten free flour mixture since I have Celiac and can't have wheat flour. I find that the GF mixes will often work with recipes that call for only a small amount of flour like this one. But you never know, it might not work at all, which I'm also used to having happen. We'll see.... 🙂
Hi Judi! I'm quite sure the recipe will work out well with gf flour, but if doesn't work out, you can still make banana bread chocolate chunk cake balls! 😀
Will do. Everyone asked for seconds, so I will be making it again sometime!
Glad everyone liked it! <3 <3
I just made this (it's currently sitting in the oven, smelling delicious)! If my family likes it, I would like to share it to AllRecipes.com. Would you be okay with that? Of course, I would give you credit in any way possible.
Awesome to hear it Amanda! Sure, as long as the credit is given, feel free to to share it 🙂 I hope you guys like it! Let me know!
Ugh, this is SO calling my name right now! I try not to cook too many desserts because I always overindulge, but this one is totally making my mouth water right now. I love chocolate and I think my brother loves it even more... gotta save this one for later!!
Thank you Whitney! Yes you guys will love this especially the custard layer! <3 🙂
