Ingredients
Before you start to make this mini chocolate cake recipe, measure and prepare your ingredients so the cooking process will go smoothly and easily.
Flour– I used all-purpose flour for this recipe. Self-rising flour and cake flour will work great as well.
Dutch cocoa powder– I like to use Dutch-process cocoa powder for our cake because I like the deep and rich chocolate taste, but the natural cocoa powder will work great as well!
Baking powder and baking soda – to allow the cake to rise. Make sure that your baking powder and baking soda aren’t expired.
Granulated sugar– I like to use granulated sugar, also the most common sugar used in baking. Castor sugar will work great as well.
Vegetable oil – I used vegetable oil for this recipe. Canola oil will work great for this recipe.
Eggs– to give the cake a good structure. Make sure you’re using room-temperature eggs.
Buttermilk– gives the cake extra moisture. You can make your own buttermilk if you don’t have one on hand. Simply mix a cup of milk with a tablespoon of vinegar or lemon juice and let it sit for at least 10 minutes.
Hot coffee– make a strong hot coffee, you can use espresso, or instant coffee, both will work.
Vanilla extract– vanilla extract is an essential ingredient for baking.
Salt– I used kosher salt for this recipe. Salt doesn’t give the cake a salty taste; it helps to enhance the chocolate flavor.
For the chocolate frosting
Butter- Use unsalted butter that is at room temperature. Remove the butter from the fridge 1-2 hours before making the frosting.
Dark chocolate- Use the best quality semisweet or dark chocolate bars for the best flavor. Using the best quality dark chocolate is very important in this recipe.
I used Scharffen Berger chocolate. Their new 62% semisweet dark chocolate baking portions are perfect for this recipe.
Powdered sugar- you will need powdered sugar for this recipe. You don’t have to buy powdered sugar; you can simply make it at home by blending granulated sugar in a blender or food processor.
Cocoa powder- You can use Dutch-processed cocoa powder or natural cocoa powder for this.
Instructions
Preheat an oven to 180°C (350°F) and prepare an 8x8 inch cake pan with parchment paper.
Into a large mixing bowl, add the eggs, vegetable oil, vanilla extract, salt, buttermilk, and sugar, and sift the cocoa powder. Mix with a whisk until well combined.
Add the flour, baking powder, baking soda, and hot coffee, and mix with a whisk until well combined.
Pour the batter into the prepared baking pan and bake in a 180c (350f) preheated oven for about 30 minutes or until a toothpick inserted into the cake comes out clean.
Make the chocolate buttercream
Into a large mixing bowl, add the soft butter, powdered sugar, heavy cream, cooled dark chocolate, kosher salt, and vanilla extract, and sift in the cocoa powder. Mix on low speed until the frosting comes together.
Increase the speed to medium to high speed and mix for about 3 minutes until the frosting is silky and smooth.
Top the room-temperature cake with the frosting and make a wave pattern with a spatula.
Expert Tips
- Don’t skip the coffee in the cake, you can’t taste the coffee, it simply enhances the chocolate flavor.
- Use room temperature ingredients. It is important that you use room-temperature ingredients like eggs and buttermilk. This step ensures that your mixture mixes into a homogenous mixture and bakes perfectly.
- Don’t overmix the batter, you don’t want to develop the gluten in the flour. This step ensures you have moist cake and not dense and dry cake.
- Make sure that you are using fresh ingredients like baking soda and baking powder. If they are expired your cake will not rise up beautifully.
- Line your baking pan with parchment paper! This step helps the cake to bake evenly, and it makes sure that your cake will release easily from the pan.
- Serve at room temperature for optimal taste. Bring the chocolate cake to room temperature before serving to ensure that the frosting is creamy and not hard and will melt in your mouth.
- Measure your flour correctly! When measuring your flour, avoid scooping it with a measuring cup. Instead, stir the flour with a spoon to create as many air pockets as possible, and spoon it into your measuring cup. Finally, level it with a back of a knife.
- Let the cake cool for at least an hour before frosting. This prevents crumbling and ensures the frosting won't melt.
- Serve at room temperature for optimal taste. Bring the chocolate cake to room temperature before serving to ensure that the frosting is creamy and not hard and will melt in your mouth.

I like to use Dutch-processed cocoa powder because it gives the cake a deeper, richer chocolate taste. I highly recommend not replacing the Dutch cocoa powder with natural cocoa powder.
No! you can’t taste the coffee. Adding the coffee simply enhances the chocolate flavor. So, don’t skip the coffee on the cake!

Rich and delish is spot on! This cake is absolutely delicious. Moist and dense crumb with rich chocolate taste and the frosting is next level scrumptious. Perfect size for a small family. Best chocolate cake I have ever made and I’m old! Thank you for this recipe!
Layla Schaerer
This was the best chocolate cake ever!!!
deb
can castor sugar be used instead of granulated
RichandDelish
Yes.
deb
I am wanting to bake this cake, but our australian cups are different, if I am using 270g of flour(1 3/4 cups) will the ratio of the baking powder and baking soda remain the same? Also could I sub the all purpose flour for self raising?, if so, would I still need to use any baking powder and baking soda
Thanks
RichandDelish
Hi Deb, I suggest weighing the ingredients in grams for the most accurate measurements.
Stephanie Joos
I’ve never had luck baking chocolate cake from scratch so I grabbed this recipe because it’s smaller and it’s just me and my husband so it seems perfect. It is currently cooling, but I like the way it smells and it looks good and I’m sure that it will taste delicious.
Sam
I baked it in an 8” round metal plan and it took about 45 minutes instead of 30. I also topped it with a powder sugar dusting instead of the icing. It came out great!
Linda
Hi I know this cake will be good! Can I substitute heavy whipping cream for the buttermilk? Or will it alter the texture of the cake? I have all the ingredients but can’t afford to buy buttermilk right now. Ty.
RichandDelish
Hi Linda, you can make homemade buttermilk with milk and lemon or vinegar. Simply mix a cup of milk with a tablespoon of vinegar or lemon juice and let it sit for at least 10 minutes. Hope this helps.
Helena
Delicious, even better the next day.
Made a ganache as frosting, Yum!
doris
the cake looks good but I would have to use water not coffee since I don't rink the stuff
Jessie
I made this recipe a couple of weeks ago. Holy mama it is good. I'm not someone who bakes cakes often but I've been wanting to practice without making something massive. This cake was delicious and the recipe was easy to follow. I will be back for more :).
Debra
made this cake to day iam so upset.. it sank in the middle. it is cooked . this has never happened to me
RichandDelish
That is can happen for a variety of reasons. This could happen if you didn't measure your flour correctly, didn't preheat the oven, or opened the oven door in the middle of it baking.
Ash
Could this be halved and baked in an 8" x 4" loaf tin? If so how should the baking time/temperature be adjusted?
RichandDelish
Yep! The baking time should be about the same, but check it 5 minutes before the timer stops. When a toothpick inserted into the cake comes out with a few moist crumbs, it's ready!
Becky
Best recipe for chocolate cake!
