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– we used all-purpose flour for this recipe, self-rising flour, and cake flour will work great as well.
Dutch cocoa powder– we like to use Dutch-process cocoa powder for our cake because we 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.
Granulated sugar– we like to use granulated sugar, also the most common sugar used in baking. Caster sugar will work great as well.
Vegetable oil – we 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– We 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 for this recipe. Only butter will work for this recipe, no margarine, and no coconut oil. Margarine has a weird taste and can ruin the flavor of this delicious frosting.
Dark chocolate- I used Scharffen Berger chocolate. Their new 62% semisweet dark chocolate baking portions are perfect for this recipe. I love using high-quality dark chocolate for baking and it's important to use the best quality chocolate for the best flavor and results!
Powder 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- I also used Scharffen Berger cocoa powder for this recipe. You can use dutch processed cocoa powder or natural cocoa powder for this.
Kosher salt- to balance out the sweet flavor.
Vanilla extract- vanilla extract is an essential ingredient for frosting.
Milk- use whole milk for this recipe.
Step 1: Preheat an oven to 180c (350f) and prepare an 8x8 inch cake pan with parchment paper.
Step 2: Into a big 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.
Step 3: Add the flour, baking powder, baking soda, and hot coffee, and mix with a whisk until well combined.
Step 4: 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 big 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.
- Use room temperature ingredients. It is important that you use room-temperature ingredients like eggs and butter. This step ensures that your mixture mixes into a homogenous mixture and bakes perfectly. you don’t want to place cold batter into the oven.
- 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 your butter is at room temperature. An hour or two before making this cake, take the butter out of the fridge and let it come to room temperature. The butter should be soft to the touch. If your butter is too cold, it will be harder to mix and there will be lumps of butter in the frosting.
- 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.
- Before you start to make this recipe, measure and prepare your ingredients so the cooking process will go smoothly and easily.
- Be patient! I know it’s extremely tempting to eat and frost this cake as it's pulled out of the oven, but let the cake cool for at least an hour so it will be firmer and won’t crumble up. This step ensures that the frosting won’t melt off the cake. You never want to frost warm cupcakes or cakes.
We like to use Dutch-processed cocoa powder because it gives the cake a deeper rich chocolate taste. We 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!
Yes! You can use any kind of your favorite frosting on this cake, this cake is very versatile so you can turn it into whatever you want! You can use chocolate frosting, vanilla frosting, caramel frosting, etc.
This cake will last up to 5 days stored in the fridge. Cover the cake with plastic wrap or foil to prevent it from drying out. This cake tastes amazing the day after.
Freeze this cake after it cooled completely in an airtight freezer-friendly container for up to 3 months, some people find the cake tastes better after freezing it.
Frosting- you can use your favorite frosting for this cake like classic chocolate frosting, caramel frosting, chocolate ganache frosting, dark chocolate frosting, etc.
Cupcakes- make this cake into cupcakes! This batter will make about 8 cupcakes.
There are a few substitutions that may be helpful for your diet:
Gluten-free - if you want to make this recipe gluten-free, simply replace the flour with gluten-free flour.
Dairy-free- you can make this cake dairy-free by replacing the butter with vegan butter or using your favorite dairy-free chocolate ganache.

made this cake to day iam so upset.. it sank in the middle. it is cooked . this has never happened to me
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.
Could this be halved and baked in an 8" x 4" loaf tin? If so how should the baking time/temperature be adjusted?
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!
Best recipe for chocolate cake!
Moist and fluffy chocolate cake. So delicious.
