Chocolate cream cake

I'm amused now, but the first time I tried to make this cake, I melted all the chocolate in the microwave and forgot it there, so it burned and turned into a gooey mess that was unusable. Then I had moments when I impatiently put the hot cake layer over the cream, and guess what, it all oozed out, and I had to scoop it up with a spoon afterward. Since then, I've learned to gather myself and be patient – plus, I've kept some little tricks, like using quality chocolate and not skimping on the mascarpone. I make it quite often, especially when someone drops by unexpectedly and I want to show them I'm not just slapping salami on bread. Well, and if there are leftovers, they never last long in the fridge, I’ll be honest.

Let me give you some quick info: it’s not a complicated work of art, but you need to stick around it a bit. Total time including chilling? About 3 hours, but only half of that is actual work, the rest is waiting. It easily serves 10-12 portions, unless someone sneaks a piece at the corner. I think even someone less experienced with baking could manage it, but it’s easier if you have a mixer. Difficulty level: somewhere around medium, meaning you don’t need pastry school, but I wouldn’t recommend doing it with your eyes closed.

I make it often for a very simple reason: it gets eaten quickly, it’s not overly rich (though, if you add too much jam, be careful), and the cake layer comes out slightly like a moist sponge, just the way I like it. It’s one of the few cream cakes that people actually come back for “I want another piece,” not just out of politeness. Plus, I don’t need expensive ingredients or any fancy techniques.

Alright, let me list the ingredients and their roles, so we don’t miss anything:

For the cake layer:
130 g dark chocolate (preferably over 50% cocoa, for that serious chocolate flavor, not something cheap)
1 tablespoon instant coffee (gives a boost to the chocolate, doesn’t taste like coffee, just intensifies the aroma)
60 ml hot water (about 1/4 cup, to melt everything and help mix)
4 large eggs, separated (yolks for creamy texture, whites add airiness)
100 g sugar (half for the yolks, half for the whites)
1 teaspoon vanilla extract (I always add it; without it, it doesn’t smell good enough)
a pinch of salt (enhances the chocolate flavor, don’t skip it)
1/4 teaspoon cream of tartar (or vinegar/lemon juice, helps with beating the egg whites, not essential if you don’t have it)
30 g flour (about 1/4 cup, just enough to bind the mixture – if you want it gluten-free, use starch or a special mix)

Filling/cream:
150 g dark chocolate (again over 50%, otherwise it’ll be too sweet with the mascarpone)
60 ml milk (helps melt the chocolate smoothly and keeps it creamy, not like concrete)
250 g mascarpone (for texture and “body” in the cream, so it’s not runny)
3 tablespoons powdered sugar (I say 3 tablespoons at first, but I always taste – depends on the chocolate)
300 g heavy cream (not vegetable-based, 30-35% fat, otherwise it won’t whip well)
2 teaspoons powdered sugar (for the whipped cream, not for the mascarpone)
1 packet whipped cream stabilizer (use it if it’s warm in the kitchen or if you’re nervous about the whipped cream)
200 g strawberry jam (other tart fruits work too to cut through the chocolate; if you use overly sweet jam, it becomes heavy)

For the glaze:
50 g dark chocolate
1 tablespoon milk
10 g butter (don’t use margarine, it gives a totally different taste)
Optionally, whipped cream and strawberries for decoration (any tart fruit works, even raspberries)

Now, let me walk you through the steps, just as I do them (with a few notes along the way):

1. Melting the chocolate for the cake layer.
I break the chocolate into small pieces and put it in a metal or glass bowl, directly over a pot of gently boiling water, so it’s a double boiler, because otherwise, I risk burning it (you don’t want to taste bitter chocolate). I also add the instant coffee and hot water to the mixture – to melt everything beautifully. Let it melt, stir gently, but don’t leave it unattended. It shouldn’t boil, just soften and become shiny. Once everything is melted, take it off the heat and let it cool for 5 minutes.

2. Preparing the eggs.
I put the yolks in a bowl and sprinkle half of the sugar (50 g) over them. I beat them well with a mixer or a whisk if I feel like exercising, until they lighten in color and become frothy. I add the vanilla now, to infuse everything. Then, patiently, I pour the melted chocolate over the yolks, a little at a time, so I don’t cook the yolks suddenly. I mix gently until it’s well combined.

3. The egg whites – I’m not rushing here.
I beat the egg whites separately with a pinch of salt, starting slowly to break them up, then I turn the mixer to high speed. When I see white foam, I add the cream of tartar (or vinegar/lemon juice, half a teaspoon). We continue and gradually add the rest of the sugar, patiently, one tablespoon at a time, so it dissolves and the meringue becomes firm, shiny, and holds its shape on the whisk. Many rush this step and let the mixture collapse in the oven – don’t skip the steps!

4. Assembling the cake layer.
I fold the meringue and flour into the chocolate mixture with large, gentle movements, from the bottom up, to keep the air (don’t rush or mix in a circular motion, it will deflate). I alternate: a little flour, a little egg white, then flour again, then egg white, that’s how it works best. Is the mixture ready? I preheat the oven to 180°C (medium heat). I line a baking tray about 35x25 cm with parchment paper – not with butter directly, as it will stick.

5. Baking.
I pour the batter into the tray, leveling it gently with a spatula. It’s liquid, don’t be scared, that’s how it should be! I bake it for about 12-15 minutes (for me, it was done after 13 minutes). It’s good when it passes the toothpick test, but don’t leave it too long, or it won’t be moist anymore. I take it out, flip it onto another piece of parchment paper, gently peel off the original paper, and let it cool completely. If it’s warm, don’t put a towel over it, only after it has cooled (to avoid condensation and make it gummy).

6. The chocolate cream.
I melt the chopped chocolate in small pieces over low heat with the milk in a small pot with a thick bottom – I stir constantly, as I don’t want it to stick. Once it’s melted and I have a shiny cream, I take it off the heat and let it sit for about 10-15 minutes. Meanwhile, I put the mascarpone with 3 tablespoons of powdered sugar and beat it a bit until it becomes creamy (don’t overdo it, don’t beat it too hard, or it can curdle). After the chocolate has cooled, I pour it over the mascarpone and mix well. This gives all the creaminess, trust me.

Separately, I whip the cold cream with a mixer (about a minute at medium speed), then I add the stabilizer and 2 teaspoons of powdered sugar and mix until it thickens. Once it’s whipped and holds its shape, I gently fold it into the chocolate mascarpone cream with movements from the bottom up, to keep it airy. I refrigerate the cream for at least an hour, even two if I have time.

7. Assembly.
I cut the cooled cake layer in half lengthwise (I use a ruler and a long knife) to get two equal layers. I place the first layer on a serving platter, spread about three-quarters of the cream over it, and level it gently. On top of the cream, I add the strawberry jam, not too thick, just enough to taste it. I place the second cake layer on top. I spread the remaining cream over the top or just a thin layer if I want a thicker glaze. I let it chill for about 30 minutes.

8. Glaze.
In a double boiler (yes, the old method, not in the microwave!), I put the chopped chocolate with the butter and milk. I stir until it melts nicely, resulting in a thinner glaze, not too thick. I pour it over the cake and quickly level it with a wide knife or spatula. If you want a thicker glaze, double the quantities, but I prefer it this way, just enough not to cover the cream completely.

9. Decoration.
I chill the cake for a few hours, usually overnight, to set everything. When I cut it, I decorate each piece with whipped cream and (optionally) sliced strawberries if I feel like adding something extra.

USEFUL TIPS

Common mistakes
- Not beating the egg whites enough or mixing too much at the end and the cake deflates – it needs to stay airy.
- If you put the warm cake in the fridge, it will create condensation and become soggy.
- Don’t pour hot cream over the mascarpone or whipped cream, it can curdle. Everything should be at least at room temperature.
- Don’t overdo it with the jam/jelly; it can become too sweet and ruin the balance. Just enough to have flavor, not a thick layer.

Ingredient substitutions/adaptations
- Gluten-free: use starch or special flour. I’ve tried it and it works.
- Lactose-free: use lactose-free mascarpone and cream; there are good options available now.
- Jam: any tart fruit works, raspberries, currants, or even quick-set fruit jelly.
- Chocolate: I recommend not going below 50% cocoa, or else it won’t balance with the other ingredients.
- Cream of tartar: if you don’t have it, vinegar or lemon juice works fine, just don’t use too much to avoid a strong taste.

Variations:
- You can add a thin layer of toasted nuts between the cake layers if you like; it gives a nice texture.
- If you don’t want too much cream, make half the amount; it will come out lighter but still good.
- For kids, skip the coffee (it’s not a big deal, it’s for aroma, not coffee flavor).
- If you want a cake, assemble it vertically, using 3 round layers and cream in between. It works!

Serving ideas:
- The cake pairs well with coffee, but also with cold milk or a tart tea, like berry.
- You can cut it into small squares and place them on a colorful platter for a mini buffet.
- It goes wonderfully alongside vanilla ice cream when you have guests.

FREQUENTLY ASKED QUESTIONS

1. Can I make the cake layer a day in advance?
Yes, it’s actually better. Wrap it in foil and refrigerate it so it doesn’t dry out. Make the cream on the day you assemble it.

2. Can the cake be frozen?
I’ve tried it; it works if you portion it beforehand and wrap it individually. After thawing, the cake layer becomes a bit moister, but still good.

3. What do I do if my whipped cream won’t whip?
Make sure it’s very cold and that the bowl is grease-free. If it’s warm in the kitchen or you’re using vegetable cream, it won’t whip well. You can also try using a stabilizer or add a bit of dissolved gelatin when warm and cooled.

4. Can I use a different type of chocolate?
Milk chocolate works, but reduce the sugar in the cream and cake, or it will be too sweet. I’ve also tried it with caramel chocolate; I didn’t like it as much, but no one will complain if you have leftovers.

5. Can I make it without eggs?
Unfortunately, the eggs are the base for the cake. You can try vegan options with aquafaba, but it will be a completely different cake, and the texture won’t be the same.

6. What do I do if I don’t have mascarpone?
You can try using cream cheese and a bit of heavy cream, but the taste will be slightly different, and it may come out a bit tangy.

NUTRITIONAL VALUES

I’m not a nutritionist, but I calculated based on the ingredients. For a decent portion (about 1/12 of the cake), you get around 350-400 kcal. Each slice is rich in fats (about 25-28g), mostly from the cream and mascarpone, some protein (5-6g/portion), and carbohydrates around 30-35g, mainly from sugar and jam. For a chocolate dessert, it’s not bad, especially if you don’t eat three slices at once. Plus, it’s not loaded with additives or vegetable oils – if you use real cream and mascarpone. If you want to cut calories, reduce the jam or use less cream when serving.

HOW TO STORE AND REHEAT

This cake keeps well in the fridge for 3-4 days without any issues if you cover it with foil or a lid to prevent it from absorbing fridge odors. After 2-3 days, the cake layer may soften a bit, but it won’t become gummy if it was cooled properly at the start. Don’t reheat it; it’s not the kind of cake for the microwave or oven – the cream will curdle, and the glaze will melt. Just take out the portion you’ll eat about 15-20 minutes beforehand, so it’s not rock hard. If it’s already portioned, even longer. It’s also great packed for the office, just don’t keep it next to something with a strong smell (like salami), or it will pick up the aroma. If you want to keep it for longer, portion it and freeze it, then let it thaw slowly overnight in the fridge.

That’s about it. I don’t even know if there’s a chocolate cake that gets devoured faster at my place. There’s always just the parchment paper left and some crumbs.

We melt the dark chocolate in a bain-marie together with the coffee and water. We let it sit until completely melted, then remove it from the heat and set aside. The egg yolks are whisked with half of the sugar until they lighten in color. We gradually add the chocolate and mix until homogeneous. We also add the vanilla extract. The egg whites are lightly beaten with salt. When they become frothy, we add the tartar and mix well until we achieve a stiff foam. We add the remaining sugar one tablespoon at a time and mix well after each addition until the sugar is completely dissolved. If you do not have cream of tartar, you can use the same amount of vinegar or lemon juice. We incorporate the flour and egg whites alternately into the egg and chocolate mixture with gentle bottom-up movements. We preheat the oven to medium heat and line a 35/25 cm baking tray with parchment paper. We pour the mixture into the tray and level it carefully. The mixture will be quite liquid and slightly aerated, which is how it should be. We bake the cake for 12-15 minutes depending on the oven. We remove the cake from the tray and turn it onto a piece of parchment paper. We let it cool completely there, then cover it with a kitchen towel. For the cream, we proceed as follows: we melt the chocolate over low heat together with the milk. We remove it from the heat and let it sit for 10-15 minutes. We lightly mix the mascarpone with 3 tablespoons of powdered sugar until it becomes creamy. We incorporate it into the chocolate cream and then refrigerate. We whip the cream for one minute at medium speed. We add the stabilizer, powdered sugar, and continue whipping until it holds peaks. We gently fold the whipped cream into the chocolate cream with bottom-up movements. We refrigerate the cream for an hour. We quickly move on to assembly. We cut the cake in half vertically to obtain two equal layers. We spread cream on one layer, level it nicely, then add strawberry jam and level it again. We cover it with the second layer and refrigerate the cake for half an hour. We quickly prepare a chocolate glaze from dark chocolate, butter, and milk, which we melt in a bain-marie. We cover the entire cake with this glaze. The glaze is not much, so the layer will be quite thin. You can double the quantities for the glaze if you want a thicker layer. The cake should be left to cool for several hours, preferably overnight, then it can be easily sliced. Each piece is decorated with whipped cream, possibly also strawberries, and it’s ready. Enjoy your meal!
