Cake 'Natasha' – classic recipe from Soviet times
Instructions
To prepare a single sponge layer, pour 100 grams of granulated sugar into a deep mixing bowl. Granulated sugar gives the most reliable consistent results, though caster sugar also works well in this recipe if that is what you happen to have on hand at home today.
Crack one chicken egg into the bowl with the sugar. The egg should be at cool room temperature rather than straight from the refrigerator for the most reliable whipping in the next step of the recipe.
Using an electric mixer on medium speed, beat the sugar with the egg thoroughly until the mixture turns pale and noticeably increases in volume. The whipping incorporates air into the mixture and produces a lighter sponge layer.
Add 100 grams of sour cream to the egg-and-sugar mixture. Sour cream of any fat content works well in this recipe, though the slightly richer 20 percent variety produces the most tender finished sponge layer.
Add the slaked baking soda to the bowl. To slake the soda, mix half a teaspoon of baking soda with half a tablespoon of vinegar in a small bowl and let it fizz briefly. Apple cider vinegar works particularly well for sweet bakes since it adds no unpleasant flavour notes.
Sift in 100 grams of plain flour through a fine-mesh sieve. Sifting at this stage adds extra air to the batter and helps the sponge rise to its maximum height during baking, while also catching any small lumps before they can disappear into the wet mixture.
Chop the walnuts in any convenient way: a sharp knife on a wooden board, a small electric chopper or a quick pulse in a food processor. Aim for pieces about the size of small lentils for the best textural contribution to the finished sponge layer.
Add 50 grams of the chopped walnuts to the batter and mix everything well with the electric mixer until uniform. Prepare all three layers in exactly the same way, only changing the filling for each one (walnuts for the first, poppy seeds for the second, raisins for the third).
Grease a round baking dish thoroughly with vegetable oil. Pay particular attention to the corners and the edges of the dish where ingredients tend to stick most stubbornly during baking.
Spread the prepared batter evenly into the greased mould. Smooth the surface with a small offset spatula or the back of a spoon to ensure the layer bakes evenly to a uniform thickness across the entire surface.
Place the dish in a preheated oven and bake at 180 degrees Celsius for about 10 to 15 minutes until properly cooked through. Check doneness by piercing with a wooden toothpick or skewer. If the toothpick comes out clean and dry, the layer is ready.
Prepare the other two sponge layers in exactly the same way, simply substituting poppy seeds for the second layer and raisins for the third. The end result will be three distinct sponge layers, each carrying a different traditional filling for visual and flavour interest in the finished cake.
Now prepare the cream for the cake. Mix one whole can of condensed milk with the softened butter in a deep mixing bowl. The butter must be properly softened to room temperature for smooth incorporation without any lumpy chunks remaining.
Whip the condensed milk and butter together with an electric mixer on medium speed until completely smooth and uniformly pale yellow throughout. The cream for the cake is now ready to use in the assembly step that follows next.
Once all three sponge layers have cooled completely on a wire rack, proceed with the assembly. The order of the layers can be absolutely your choice. Place the first layer on the serving plate and spread it generously with the prepared condensed-milk cream.
Place the second sponge layer carefully on top of the cream-covered first layer. Press very gently with flat hands to settle the layer into place without compressing it.
Spread the second sponge layer with another generous layer of cream, smoothing it out evenly to the edges with a small offset spatula or the back of a spoon.
Place the third and final sponge layer on top of the cream-covered second layer. Again press very gently with flat hands to settle everything into place.
Spread the very top of the third layer with a final generous coating of cream. Use the remaining cream to cover the sides of the cake too if you wish, for a more polished finished appearance on the celebration plate.
Sprinkle the top of the finished Cake Natasha generously with coloured pastry sprinkles, grated chocolate, chopped nuts or any other confectionery decoration you fancy. To allow the cake to soak properly, place it covered in a cool place for a few hours, ideally overnight until morning.
Cut the rested cake into wedges with a sharp knife dipped briefly in hot water and wiped dry between each cut for the cleanest professional-looking slices on the dessert plate. Cook the cake Natasha according to this classic recipe and bon appetit!
Tips
- 1
Bake all three sponge layers consecutively rather than simultaneously, since the layers are too thin to bake reliably stacked on top of each other on the same oven shelf. Wait for the first layer to come out and the oven to recover its temperature before sliding in the next one. The slight extra time is well spent, since rushing this step can produce uneven layers that ruin the visual symmetry of the finished celebration cake.

Soak the raisins briefly in warm water or rum before adding to the third sponge layer for plumper softer fruit in the finished bake. To pair this beautiful Soviet-era classic with another beloved homemade dessert from the same culinary tradition, try our richly indulgent Mousse Cake Three Chocolates as a more dramatic alternative for special celebrations.

Allow the assembled cake to rest in a cool place for the full overnight period, since the resting time lets the cream soak into the sponge layers properly and produces the characteristically moist tender texture this cake is famous for. Skipping the rest produces a noticeably drier less integrated finished cake that lacks the proper character of a true Soviet-era Natasha. Patience is genuinely essential.

Use properly soft butter at full room temperature for the cream, since cold or barely-softened butter will not incorporate smoothly into the condensed milk and produces a lumpy disappointing finished cream. For another classic homemade cake to add to your celebration repertoire, try our beautifully creamy Bounty cake with coconut flakes as a sweeter chocolate-and-coconut alternative.
FAQ
Can I use one filling for all three layers? +
Absolutely. Using a single filling (typically walnuts) across all three layers produces a beautifully consistent finished cake that some bakers actually prefer to the traditional three-filling version. Triple the quantity of your chosen filling to fill all three layers properly. Alternatively, you can mix and match in interesting ways: try walnuts plus chopped chocolate, raisins plus dried apricots, or poppy seeds plus a teaspoon of vanilla extract for unusual but delicious flavour combinations.
What can I use instead of condensed milk? +
Sweetened mascarpone cream, whipped double cream with icing sugar, or a homemade pastry cream all work as alternatives to the traditional condensed-milk butter cream in this recipe. Each substitute produces a noticeably different finished cake: mascarpone gives a tangier richer result, whipped cream stays lighter and fluffier, and pastry cream produces a more refined silky finish. Whichever cream you choose, allow the assembled cake to rest overnight for the best texture.
How long does this cake keep? +
Store the assembled cake covered loosely in the refrigerator for up to four full days for best results. The flavours actually improve significantly during the first two days as the cream continues to soak deeper into the sponge layers and merge with the various fillings into a beautifully harmonious whole. Avoid freezing the assembled cake, since the texture suffers significantly during defrosting and the whole carefully constructed dessert turns soft and watery in the container.
Can I bake this cake without slaked soda? +
Yes, replace the slaked baking soda with one teaspoon of baking powder for similar leavening effect without the need for vinegar. Baking powder works in any recipe but produces a slightly less dramatic rise than properly slaked soda combined with the natural acidity of the sour cream in the recipe. The finished sponge will be slightly denser but still perfectly tender and delicious in the assembled cake. Both methods produce excellent results in skilled hands.
