Hello there! Before you browse, there’s a lot of vital information in this article!includes the FAQ section, which may help you with any queries you have regarding this recipe. Enjoy!

Ingredient Notes:

Let’s have a look at some of the ingredients used in the cake and buttercream recipes. (All of the ingredients are included in the recipe card below.)

All-purpose flour: This recipe calls for basic all-purpose flour, so no special flour is required. When measuring the flour, be sure you scoop it into the measuring cup rather than packing it in. (For further information, see the FAQ section below.)

Natural unsweetened cocoa powder: This is what gives the cake and buttercream a deep chocolate taste. Use raw unsweetened cocoa powder rather than Dutch-processed cocoa powder. (For further information, see the FAQ section below.)

Baking powder and baking soda will be used in this recipe. They’ll both help the cake rise, but baking soda is also required since cocoa powder is acidic.

Unsalted butter: This will be used in the cake as well as the buttercream. A little melted butter in the cake adds a small buttery flavor and simply makes this cake a little more tasty than a chocolate cake cooked just with oil.

The butter in the icing is what gives it that delicious buttercream flavor and smoothness.

Buttermilk: Using buttermilk in cakes gives the cake a soft texture and improves the flavor. Don’t worry, it won’t make the cake taste like buttermilk. (If you have any queries regarding substitutes, please see the FAQ section below.)

Hot coffee or water: The coffee improves the chocolate taste but is insufficient to give the cake a coffee flavor. If you don’t have any coffee or just dislike the concept of using it, boiling water will suffice.

How to make this cake:

Let’s get started on making this chocolate mini cake. (Details are also included in the recipe card below.)

Step 1:

To begin, preheat the oven to 350 degrees Fahrenheit and butter and flour (or spray) two 6 inch round cake pans that are 2 inches deep.

Step 2:

Add all of the dry ingredients (flour, cocoa powder, baking powder, baking soda, salt, and sugar) to a large mixing bowl. Set it aside after thoroughly mixing it with a whisk.

Step 3:

Now, in a separate mixing dish, whisk together all of the liquid ingredients (except the hot water or coffee).

Step 4:

Then, combine the liquid mixture (save for the coffee or water) with the dry mixture. Mix with an electric mixer until the ingredients are well mixed. Then, scrape down the sides of the basin and mix for just a few seconds longer.

Step 5:

Now add the hot coffee (or hot water) and stir until fully blended, but don’t overmix.

Step 6:

Pour the mixture into two 6 inch round cake pans and bake the cake layers for 35-40 minutes at 350 degrees F.

Step 7:

While the cake layers bake, prepare the buttercream, cover, and put away.

Step 8:

After baking, chill the cake layers on wire racks for approximately ten minutes.

Step 9:

After that, remove the cakes from the pans and cool entirely on the racks.

Step 10:

After the cakes have cooled, level them with a knife. (Remove any domes from the cake.)

Step 11:

Add a layer of cake on a cake plate or cake board and top with buttercream, then add the second layer of cake and cover with buttercream. You may then decorate the cake with piping if desired.

Step 12:

Enjoy with sprinkles or any other pattern you like!

Tips & FAQs:

What size are mini cakes?

In general, any cake smaller than an 8-inch cake might be considered a little cake. This small cake recipe makes a six-inch two-layer cake.

How many people does a 6-inch chocolate cake feed?

This cake will feed around 8 people. Larger slices will serve fewer people, whereas thin slices will serve more people.

Tip for measuring flour:

Make cautious not to overfill the measuring cup with flour. Spoon the flour into the cup and level it, but do not scoop it. Packing too much flour into the measuring cup will result in too much flour being added to the cake mix, making the cake dry and tough.

Do I have to use natural unsweetened cocoa powder, or can I use Dutch-processed?

Don’t use Dutch-processed cocoa for this cake since it isn’t as acidic as natural cocoa powder and would need adjustments to the other components. See this link for additional information on the many varieties of cocoa powder: What kind of cocoa powder should I use?

Can I substitute the baking soda for baking powder or vice versa?

You do not want to do that. These are distinct and cannot be exchanged for one another. If you want to learn more about the distinction, read this blog post: Baking Soda vs. Baking Powder

Can I use salted butter instead of unsalted?

Unsalted butter is usually preferable since you can anticipate the quantity of salt that will be applied, and salted butter has a different water content than unsalted butter. If you can’t find unsalted butter, you may use salted butter in the cake and buttercream, but leave out any extra salt that each recipe asks for.

Can I substitute buttermilk?

Buttermilk is ideal for this recipe since it creates a softer texture and enhances the taste of the cake. If you can’t get it, use this sour milk recipe instead:Fill a measuring cup halfway with ordinary milk, then take out two tablespoons and replace them with two teaspoons of lemon juice or white vinegar, stirring well. Allow for 5 minutes before using.This will not work precisely like buttermilk, but it will suffice in a pinch.

Do I have to use the coffee?

You don’t have to, but know that if you do, the cake will not taste like coffee. The coffee only enhances the chocolate taste. If you don’t like the notion of using it, you may substitute water and it will taste just as good. Just be careful not to leave out the liquid entirely.

Batter mixing tip:

Be cautious not to over-mix the batter. Scratch cakes should not be combined for more than a few minutes at a time since they will become thick. When all of the ingredients are thoroughly combined, stop mixing.

How can I tell when this cake is done baking?

When a toothpick put into the middle of each layer comes out with a few moist crumbs or clean, but no raw batter, the cake is done.

Can this cake be frozen?

If desired, this cake may be prepared ahead of time and frozen. Allow the cooked cake layers to cool fully before wrapping in plastic wrap and foil and freezing for up to a month or two.Place the covered cake layers on the counter at room temperature to defrost thoroughly before removing the wrapper. Once defrosted, spread buttercream on top.

How do I store this cake and how long does it last?

This cake may be kept at room temperature for 2-3 days if firmly wrapped. After that, it may be kept in the refrigerator, firmly covered, for another 2-3 days to keep it fresh.

Can this cake be made into an 8 inch round layer cake?

That would need some calculation, however there is an 8-inch chocolate cake recipe on the blog that you can find here: Cake with Chocolate and Butter

Can this recipe be made into cupcakes?

This recipe should work well for cupcakes, but because to the decreased batch size, it will not yield a full two dozen. If you’re looking for a great chocolate cupcake recipe, check out this post: Best Chocolate Cupcakes.

What’s the best way to serve/eat this cake?

What can be added to this cake?

If you want to make it a double chocolate mini cake, add 1 cup of tiny chocolate chips to the batter.
