Fluffy, moist caramel base, creamy, smooth caramel cream filling and crunchy walnuts make up the special taste of the popular homemade Soviet Golden Key Cake. Not only is it incredibly delicious, it is also a sweet eye-catcher on the coffee table. You can find a detailed caramel cake “Zolotoy Klyuchik” recipe with the exact quantities and step-by-step instructions below.
Homemade Soviet caramel cake
In addition to the cake “Zolotoy Klyuchik” according to GOST, there was this caramel cake with the same name in the Soviet Union. Alongside the cake “Muraveynik”, the honey cake “Winnie-the-Pooh”, the Smetannik cake “Mishka na severe”, the cake “Damskiy kapriz” and the cake “Grafskie razvaliny”, it was one of the most popular homemade cakes.
From household to household, there were several recipes for the caramel cake, which differed slightly from one another. Soviet housewives carefully kept their recipe in their handwritten notes.
“Zolotoy Klyuchik” translates from Russian as “the golden key”. The cake got this name because of its taste. It is reminiscent of the famous Soviet caramel candy “Zolotoy Klyuchik”. It is similar with the honey cake “Korovka” and its name.
What is Golden Key Cake made of?
Cake bases
The cake bases are similar to a sponge cake. In addition, sour cream and caramelized sweetened condensed milk are stirred into the batter, just like into the batter for the cake “Caramel girl”. This makes the cake bases taste fluffy, soft and caramelized.
I also soaked them with a caramel milk syrup. It makes the cake bases incredibly moist and enhances the caramel note.
Cake cream
The cake filling consists of caramelized sweetened condensed milk, cream and butter. It tastes creamy and smooth.
Each cake layer is also sprinkled with chopped walnuts. They give the cake a nutty and crunchy note.
Soaking the cake bases
I soaked the cake bases for the Golden Key Cake with a syrup. It is made from milk and caramelized sweetened condensed milk.
I recommend that you don’t skip this step. The cake bases taste incredibly moist and even more caramelized thanks to the soaking.

How to make Golden Key Cake: tips and tricks
- The baking time specified in the recipe for the cake base may vary. Do not bake it longer than necessary so that it tastes moist and not dry. Use a toothpick to check whether the cake base is done.
- You can decorate the Golden Key Cake as you wish. I used a piping bag with a small star-shaped nozzle to pipe roses from the cream onto the cake.
- Instead of walnuts, you can use other nuts, such as hazelnuts. If you don’t like nuts, you can leave them out.
- The cake tastes best if you leave it at room temperature for a while before serving so that the cream softens.
