In Soviet times, Prague cake was hard to come by. People queued up for it in pastry shops, even though it was quite expensive. With my recipe, you can make the Russian chocolate cake, which was popular throughout the Soviet Union at the time, at home. It tastes incredibly moist, chocolatey, fluffy, creamy and simply delicious – just like the original. You can find a detailed classic Prague cake recipe with the exact quantities and step-by-step instructions below.
What is Prague cake?
Although its name might suggest otherwise, the Prague cake has nothing to do with the Czech Republic. It’s the same with the Wenceslas cake and its name.
The Soviet chocolate cake was invented by Vladimir Guralnik, then head pastry chef at the Praga restaurant in Moscow. He gave it the name of the restaurant. Incidentally, the Bird’s milk cake was also created by Guralnik.
What is Prague cake made of?
The bases for the Prague cake consist of a chocolate sponge cake. To prepare it, egg yolks are separated from egg whites. Butter is also stirred into the batter. Cocoa powder provides the chocolate flavor.
The Prague cake is filled with a chocolate buttercream. It contains sweetened condensed milk and cocoa powder.
A thin layer of apricot jam adds a change of flavor to the chocolate cake. It gives it a slightly fruity and tart note.
The Prague cake is also completely covered in chocolate glaze, just like the cake “Charodeyka”. This makes it even more chocolatey.
Soak chocolate sponge cake
It is important that you soak the sponge bases for the Soviet chocolate cake, just like for the cake “Podarochnyi”, the cake “Slavyanka” or the cake “Tavrichesky”. This is the only way to make it taste particularly moist later on.
I used the classic sugar syrup to soak the cake and flavored it with cognac, as in the original recipe. You can also use a liqueur or rum instead of cognac. You can also omit alcohol and use vanilla instead.
The sponge bases for the Prague cake are often soaked in a strong brewed black tea. First sweeten the hot tea with sugar and leave to cool.
Alternatively, you can also use coffee or a fruit syrup to soak the cake. Just experiment as you like. This way, you can give the Prague cake a different flavor every time.
How to decorate Russian chocolate cake
Traditionally, the Prague cake was decorated quite simply in Soviet confectioneries. First, it was completely covered with chocolate glaze. Then its name was also written on the cake with chocolate glaze.
This time I simply drew a net on it with melted chocolate. You can decorate the cake however you like. Sprinkle it with chopped nuts, grated chocolate or fresh berries, for example.

How to make Prague cake: tips and tricks
- Traditionally, the Prague cake is prepared with apricot jam. Alternatively, you can use another, preferably tart, jam.
- Instead of ground vanilla bean, you can use vanilla sugar or vanilla extract.
- The baking time stated in the recipe may vary. Do not bake the chocolate sponge cake longer than necessary so that it tastes fluffy and not dry. Test with a skewer to check whether it is cooked in the middle. Do not open the oven door for the first 20 minutes so that the sponge cake does not collapse.
- You can bake the chocolate sponge cake the day before, leave to cool completely and then store in an airtight container at room temperature overnight.
- You can simply omit the alcohol from the recipe.
- Stir the milk syrup continuously when heating so that it does not burn and has a smooth consistency.
- Butter and the milk syrup for the cake cream must be room warm and both at about the same temperature so that they can combine well without the cream curdling.
- Use good quality chocolate for the chocolate glaze.
- Like so many other Soviet cakes, the Prague cake tastes even better the next day. It is therefore best to leave it in the fridge overnight.
