Meet my Super Moist Chocolate Cake that tastes even BETTER on day two. This is my go-to chocolate sponge for birthdays and celebrations. You can easily make it ahead of time and you don’t need an electric mixer.
Oh chocolate cake, you dreamboat you. With a mighty moist crumb, tender texture and a deep cocoa flavour, this Moist Chocolate Cake is anything but boring. Think of it as the chocolate cake from the movie Matilda.
THIS is my go-to chocolate sponge cake. The one I make for any special occasions, birthdays and celebrations that require a finger-licking chocolate cake that must stay moist.
While I love chocolate cakes that use butter, this oil-based cake is a MUST any time you need to make a cake ahead of time.
In fact, it tastes even better on day two and day three. Unlike most baked goods that are best fresh, this cake is best, well, not fresh.
You can use it to make a layer cake or a sheet cake. No electric mixer needed! I’ve frosted it here using my easy Chocolate Ganache Frosting.
So even if this is your first time making a chocolate cake, I’ve got you covered with this easy recipe.

Recipe testing
I didn’t know I needed another chocolate cake recipe in my life. After all, we’ve been enjoying my buttery Chocolate Fudge Cake for years, and I love the moist crumb of my Chocolate Olive Oil Cake. And don’t even get me started on my Chocolate Orange Cake.
But it turns out we do. In the way that we all need a go-to chocolate sponge for ANY and every occasion.
If you need a cake for a birthday party, a graduation, an impromptu dinner party, Valentine’s Day or just because we all need a slice of damn good chocolate cake from time to time, this Moist Chocolate Cake is for you.
Why? Because it’s ridiculously easy to make. You don’t need to get out the electric mixer, just a couple of bowls and a whisk and you are DONE.
Second, it makes two large layers, so you can easily slice them in half to make a four layer cake OR opt for a simple 13 by 9 inch sheet cake. Or go for 30 cupcakes!
And thirdly, it stays moist for days. I’ll even go as far to say it is BETTER on day 2, and maybe even better on day 3!
I’ve tested a number of variations of this cake, changing up the amounts of sugar, baking powder and soda, removing the sour cream (and adding it back in) and using hot water versus coffee.
But I can confidently say that this cake is THE ONE. It’s the one I keep going back to. The one I use when I’m serving it to friends for birthdays or bringing to a potluck. It’s the one that has me reaching for just one more bite. This is the Best Chocolate Cake Recipe.
Ingredients
To make this Super Moist Chocolate Cake, you only need a handful of simple ingredients. And for those that find it hard to come by buttermilk and/or sour cream, we can talk about that below.
Here’s a quick rundown of the key ingredients you’ll need, including any substitutions you can make:
Cocoa powder: You can use either natural unsweetened cocoa powder OR Dutch processed cocoa powder in this recipe. Just don’t use drinking chocolate or any sweetened cocoa powder.
Brown sugar AND caster sugar: Using both sugars gives you the best of both worlds. Brown sugar adds moisture and flavour, while caster sugar offers sweetness. If you don’t have access to caster sugar, use granulated sugar instead. And for the brown sugar, choose regular or light brown sugar.
Oil: You will need a flavourless oil or neutral-tasting oil for this cake. I prefer to use mild olive oil or grapeseed oil as it leaves no aftertaste, but vegetable oil works too.
Buttermilk: Full fat storebought butter does wonders for making a super moist cake crumb. I highly recommend getting your hands on it if you can. If you can’t you can use a DIY buttermilk substitute by adding 1 tablespoon of white vinegar or fresh lemon juice to 240 ml (1 cup) of full fat or whole milk. Leave it to curdle for 5 minutes and then use as per recipe.
Sour cream: Likewise, full fat storebought sour cream also helps create a rich, flavourful chocolate cake. You can leave it out in this recipe – I’ve tested it and the cake is still great – it’s just better with sour cream. Alternatively, you can add full fat Greek yogurt or natural yogurt.
Hot coffee: You can use hot water or hot coffee in this cake recipe. Hot water works just fine but 1 teaspoon of instant coffee or espresso powder can help enhance the chocolate flavour.

Storage instructions
This Moist Chocolate Cake will keep well for days at room temperature. Once cooled, you can wrap it in plastic wrap and keep it at room temperature for two, three or even four days.
Beyond that, consider freezing the layers to maximise freshness. Once decorated, you can also store this cake in the fridge and it won’t go dry.
Frequently asked questions
Yes absolutely. In fact, this cake is EVEN BETTER the next day. Make it a day or two in advance – simply cover it tightly in plastic wrap and place it in an airtight container at room temperature.
Yes. You can use homemade DIY buttermilk in this recipe if you need to. Simply add 1 tablespoon white vinegar to 240 ml (1 cup) whole or full fat milk.
I haven’t tested this recipe without eggs BUT I have a brilliant Egg Free Chocolate Cake recipe you should try.
A few common reasons why your chocolate cake might be dry include adding too much flour and cocoa. Be sure to measure these ingredients using a baking scale to avoid over-measuring. Over-baking your sponges will always make for a dry cake. If you find your cakes are dry around the edges, be sure to remove them from the pans once they have finished baking – letting them cool in the pans will cause the edges to continue to cook against the hot pan. Ingredients like sugars, buttermilk and sour cream ensure chocolate cake is moist so if you change these, it can affect the overall texture in your cake.
MAKE THIS CAKE ANY SIZE OR SHAPE
Use this recipe to make two 8-inch cake layers, three 6-inch cakes, a large 9 by 13 inch sheet cake, or approximately 30 cupcakes.

Notes
Cocoa powder: You can use either natural unsweetened cocoa powder OR Dutch processed cocoa powder in this recipe. Just don’t use drinking chocolate or any sweetened cocoa powder.
Flavourless oil: You will need to choose a flavourless oil or neutral-tasting oil for this cake. I prefer to use mild olive oil or grapeseed oil as it leaves no aftertaste, but vegetable oil works too.
Buttermilk: If you don’t have access to buttermilk, you can use a DIY buttermilk substitute by adding 1 tablespoon of white vinegar or fresh lemon juice to 240 ml (1 cup) of full fat or whole milk. Leave it to curdle for 5 minutes and then use as per recipe.
Sour cream: If you don’t have access to sour cream, you can leave it out in this recipe. I’ve tested it and the cake is still great – it’s just better with sour cream. Alternatively, you can add full fat Greek yogurt or natural yogurt.
Hot water or coffee: You can use either hot water or hot coffee in this recipe. You won’t be able to taste the coffee but it does help to enhance the chocolate flavour. You can simply add 1 teaspoon of instant or espresso powder to the hot water before adding it to the cake batter.
Size and shape: You can use this recipe to make two 8-inch cake layers as pictured OR three 6-inch cakes, a large 9 by 13 inch sheet cake, or approximately 30 cupcakes.

Beyond that, consider freezing the layers to maximise freshness. Once decorated, you can also store this cake in the fridge and it won’t go dry.
Frosting: I used my easy Chocolate Ganache Frosting to decorate the cake as pictured.

Tanya says
Hi I’m tossing up between your Moist Chocolate cake made with oil or your Chocolate Fudge cake made with butter. Which is more moist? I’m going to make double the quantity for two number 1 cakes and will stack them on top of each other
Jessica Holmes says
Hi Tanya, I would go with this one. It is slightly more moist and will get more moist over time, whereas the Fudge Cake will slowly dry out.
Lauren says
This cake is amazing! Easy to make and it tasted great even days later. I made it for my son’s birthday the day before. Everyone at the party loved it. This will now be my go to birthday cake.
Jessica Holmes says
That is so lovely to hear Lauren! I am the same – it’s the best cake for parties because it stays so fresh and moist!
