If you don’t have a lot of time, and need to make a cake for a birthday or a potluck, this is the recipe for you. Including the filling, frosting, and decorating instructions, this chocolate cake recipe was designed to make the the most impressive cake with the least amount of specialized equipment. You can get beautiful results without a piping bag or tips, or any specialized cake decorating tools.
You can make this cake with a stand mixer, a hand mixer, or even a hand whisk. If you are really in a hurry or have very limited cake pans and other tools, you can bake the cake in a rectangular pan and just frost the top. I have baked this cake in a dutch oven on a campfire, near the Arctic Circle, and it was one of the best chocolate cakes I ever made!
If you have time, and want to try making a multi-layer cake like the one shown up top, you need the equipment in this picture at a minimum:
There are few things worth mentioning about the equipment I use when making cakes. First of all, note the scale in the lower left. I weigh most of my ingredients, especially compressible dry ingredients such as flour and cocoa. And frothy liquids, like buttermilk, should be weighed, because otherwise you are measuring air in the cup instead of the ingredient. Every baker needs a scale, so order one on line right away if you don’t have one!
There is nothing special about the bowls I use, but note the cake pans. I get the best success from straight- and high-sided pans. The ones I used for this cake are eight inches in diameter and three inches high. Also note the cloth strips in the pan. If you wet them thoroughly and wrap them around the outside of the pan, your cake won’t have a high dome on top that has to be cut off later when stacking layers. I use them all the time for layer cakes. Older-style home-baker cake pans have fluted sides; the top is wider than the bottom. I suppose this was thought to release the cake more easily, but fluted sides are not necessary if you prepare the pan properly. You really want straight-sided pans so you don’t have huge gaps that must be filled if you want to give your cake professional-looking smooth sides.
Note, also, the roll of parchment paper on the left. I don’t know how I baked before parchment paper. You can butter and flour cake pans as much as you want, but sometimes the bottom sticks and you can’t get the cake out. I cut a circle of parchment to match the bottom and stick it down with a dab of oil or butter. The sides are just buttered, and running a plastic knife along the inside of the pan is enough for the cake to pop out easily.
Using a combination of the proper pans and pan-strips will give you high, flat cake disks that are easily filled and frosted.
You can simply stack the two layers on top of another with some kind of filling, but the cake will be much more impressive if you slice each layer to make four layers in total. There is a tool that will do this for you accurately, but you can also use a serrated knife, such as a bread knife.
I give two recipes for fillings and frostings. Buttercreams make good frosting, but I find American buttercream, which is based on butter and a very large amount of icing sugar (powdered sugar), too sweet. Chocolate Swiss or German buttercreams are much better, and great for piping, but are too much work for this simple cake. In my opinion, the simplest and tastiest filling and/or frosting for a chocolate cake is a ganache, which is just dark chocolate and cream, or sour cream. For a two-layer cake, I would use a sour cream ganache inside and out. For a four-layer cake, I suggest filling with a whipped ganache and, optionally, frosting with a sour cream ganache. Both recipes are given.
One step used in fancier cakes that I would not leave out is soaking the layers in cake syrup. Just mix water and sugar together, bring to a boil, cool, and add some flavoured liquor, or not. Brushing the cooled syrup on each layer will increase the moistness, and add extra flavour if you used liquor.
If you are filling a four-layer cake, you have the option to stop after the final layer and just wipe the exterior with a palette knife to smooth it. That gives the cake the “naked” look, and if you are fine with it, you’re done. You can sprinkle the top with icing sugar, or top with fruit and go minimalist. In my version of this cake, I coated the top and sides with a sour cream ganache, which is probably the easiest and fastest frosting in existence.
For the final decoration, my intent was to avoid piping. If nature is the best decorator, get some fruit, slice, and arrange on top. Now you are really done.
Ingredient Notes
I suggest using cake flour for a soft texture. Bleached all-purpose is the next best thing, then unbleached. I haven’t tested this cake with spelt or whole-grain wheat flours, nor with gluten-free flours. The amounts of baking power and baking soda are specified for Dutch-process cocoa. If you have natural cocoa (like Hershey’s; read the fine print) switch the amounts to 2 teaspoons baking soda and 1 teaspoon baking powder. You can double the salt in this recipe if you like, as salt enhances the flavour of chocolate. Any oil will work. Cakes are usually made with an unflavoured oil like canola or grape seed, but olive or nut oils will add an interesting flavour note. I specify the buttermilk by weight, because if you shake it (recommended on the carton), it is highly aerated and therefore can’t be measured accurately in a cup. For the fillings and frostings, use the best quality dark chocolate (minimum 55% cocoa). Extra-dark chocolate (higher than 75% cocoa) is too bitter, as there is no added sweetening.
Print RecipeIngredients for Cake
250 g cake flour
2 teaspoons baking powder
1 teaspoon baking soda
125 g Dutch-process cocoa powder
1 teaspoon salt
400 g (2 cups) white sugar
2 eggs
140 g (2/3 cup) oil
240 g (1 cup, unshaken) buttermilk
2 teaspoons vanilla
1 cup boiling water plus 2 teaspoons instant coffee
Directions for cake
- Prepare two eight-inch, high-sided cake pans by lining the bottom with parchment paper and buttering the sides. Set the oven to 325ºF. If you have some, wrap pans in wet pan strips.
- Place flour, cocoa powder, baking powder and baking soda in a large fine sieve and sift into a bowl. Add salt and sugar to the bowl, and whisk to disperse ingredients evenly.
- Place eggs, oil, buttermilk, and vanilla in another bowl, large enough to handle the entire cake batter. Use a mixer or hand whisk to beat all ingredients until smooth and emulsified. Have the cup of boiling water with coffee standing by, but don’t add it yet.
- Add the dry mixture to the wet mixture one large spoon at a time and mix on slow speed (or fold in with a spatula) until just moistened. Add the water and coffee and start by mixing very slowly to incorporate. Then mix quickly for just a few seconds until batter is smooth and uniform.
- Pour into prepared cake pans. Bake for 35 – 40 minutes, or until a cake tester comes out clean. Remove and let cool on a rack for about 15 minutes. Run a knife (plastic works best) along the inside edge of the pans and turn out cakes onto cooling rack. Cool completely, for a few hours.
Ingredients for cake syrup
1/2 cup sugar
1/2 cup water
1/4 cup rum or liqueur that would go well with chocolate
Directions for cake syrup
- Place sugar and water into a small saucepan and bring to the boil. Whisk sugar to completely dissolve. Set aside and leave to cool completely.
- Add rum or liqueur of your choice. Keep in fridge until ready to fill cake.
Ingredients for whipped ganache (4-layer version)
2 cups whipping cream, divided into 2 separate cups
225 g dark chocolate
Directions for whipped ganache (4-layer version)
- Chop the chocolate into small chunks (less than 1 cm) and place in a bowl.
- Bring 1 cup of the whipping cream just to the boil in a saucepan. Immediately pour over the chocolate. Let stand for 3 – 5 minutes. Slowly start whisking to completely melt the chocolate and incorporate into the cream. Continue whisking slowly until you have a dark, smooth, shiny ganache. Set aside to cool for an hour or two.
- Just before using the ganache, check to make sure that it is cool, but still soft enough to not resist a spoon dipped into it. If it has hardened, place in microwave for 10-second bursts until softened.
- Whip the other 1 cup of cream. Fold the ganache into it. Use immediately to fill the cake.
Ingredients for sour cream ganache
1 1/2 cups sour cream
400 g dark chocolate
Directions for sour cream ganache
- Heat sour cream by microwaving in 15-second bursts and then stirring, until room temperature or just slightly warm.
- Chop chocolate into very small chunks and melt in microwave in 30-second bursts. Stir between bursts. The chocolate will look like it isn’t melting, but it is. Be patient so you don’t scorch it. Eventually it will be completely melted and smooth.
- Fold chocolate into sour cream until completely combined. It is ready to use as soon as it cools, which can be as soon as 15 minutes.
Directions for filling and frosting 2-layer cake
- Place first layer on cake plate. Pierce top many times with skewer. Brush as much cake syrup as you can without it getting too soggy. Let stand for a few minutes to absorb. Spread some of the sour cream ganache over top. Place the second layer over, pierce and soak again, and then frost top and sides with remaining ganache.
Directions for filling and frosting 4-layer cake
- Carefully slice each layer into two. Place the bottom half of cut layer on a cake place. Soak with a quarter of the cake syrup. Place a bit less than one-third of the whipped ganache on the layer and spread evenly and level. Place the top half of a cut layer over, cut side up. Repeat soaking and spreading with ganache. Place the top half of the other cut layer over top, cut side up. Soak and spread. Finish with the bottom half of the cut layer, and soak. Use any leftover filling to smooth out the sides. If you are going for a naked cake, decorate the top and you’re done.
- If frosting the outside, place cake in fridge for an hour. Remove and cover top and sides with sour cream ganache. Decorate with fruit or anything you wish.
