When I made a chocolate school cake with chocolate custard a few weeks ago, I had a few people tell me that their school had green custard instead.
GREEN CUSTARD ???? I like green, I also like mint, so I wanted to try it.
Turns out mint custard and chocolate cake is a great combo, I loved the way this tasted.
Chocolate School Cake with Custard
If you’re not from the UK, or if you’re like me and have forgotten everything about your childhood, you might not know what chocolate school cake.
A lot of primary schools in the UK would give this cake as a desserts.
It was just a slice of plain chocolate cake, with custard on top. Some schools had regular custard, some had a pink custard and some had a green custard.
Whenever I hear people talk about this dessert, they say they love it but then they also talk about how dry it was.
I promise this recipe will not give you a dry cake, we’re recreating the school cake but making it better!
Ingredients for the chocolate cake
The cake for this dessert is pretty easy to make.
All we’re doing is mixing the wet ingredients, mixing the dry ingredients, and then putting them together.
Here’s the ingredients that are needed for the cake!
- Cocoa powder – I like to mix this with the wet ingredients. Hydrating the cocoa powder gives it a better chocolaty taste.
- Coffee – adding some coffee also gives a better chocoalty taste.
- Oil – any flavourless oil works, I like to use vegetable. I use oil instead of butter in this recipe, it makes the cake more moist.
- Plain Yoghurt – this also makes the cake more moist.
- Self-raising flour – I like to use self raising instead of plain. The only reason is because it’s easier, I don’t have to add any raising agents.
- Sugar – We’re using a mixture of brown and granulated sugar. The brown sugar gives the cake a great flavour.
Do I have to add coffee?
In the recipe, you will see that I add 100ml of hot water that has been mixed with 1 teaspoon of coffee.
Coffee in chocolate cake helps bring out the chocolate flavour.
I feel like chocolate cake always tastes so much better with a little coffee in it.
It doesn’t make the cake taste like coffee at all, if you’re worried about that.
But you could leave it out if you wanted too, just make sure to still add in the 100ml of hot water.
Substitutes for the yoghurt?
I love adding yoghurt to my chocolate cakes, it makes them so much more moist.
I like to use full fat plain yoghurt.
If you don’t have it….I recommend buying it.
But if you don’t want too, sour cream is the best substitute. Or buttermilk will work well too.
The last resort is to just use regular milk instead. The cake will be a little less moist if you replace the yoghurt with milk, but it will still be good!
Can I use a different flour?
If you’re from the US, you might not be able to get self-raising flour very easily.
You can use the same amount of plain/all purpose flour instead. Just add 2 teaspoons of baking powder to it.
Making the mint custard
Making the custard is also easy. All you need to do is add the ingredients into a pot and heat until the mixture has thickened.
Here are just a few tips!
Keep the heat on medium
The custard has egg yolks in, so you want to keep the heat on medium throughout the whole cooking process.
The reason for this is because we don’t want the eggs to get too hot, if they do, the can end up scrambling.
So then you will have pieces of scrambled eggs in your custard. We don’t want this.
You want to keep stirring during the cooking process. Try not to walk away from it.
Again, this is because we don’t want the eggs to get too hot.
But with that being said, if your eggs do scramble a little, it’s not a huge deal. We’re sieving the mixture anyway.
Sieve the custard
The last step in making the custards is to sieve is.
This is to get out any eggs that might have scrambled but also any other lumps that could have formed because of the corn flour!
The mint flavour
So to give the custard a mint flavour, I used peppermint extract.
I did try using actual fresh mint leave at first. But in order to get enough mint flavour in the custard, I had to use A LOT of mint leaves.
So I decided it’s just way easier to use peppermint extract instead.
In the recipe I wrote that you need 1-2 teaspoons of the extract. The amount if totally up to you though.
If you want a milder mint taste, add less, if you want a stronger mint taste, add more!
