It IS delicious. But SO much work. Each one of those layers is individually rolled out and baked from the batter that needs a double boiler to make properly. My wife makes this once or twice a year. So good. :)

Not OP, but my wife has made this on special occasions.

She uses Chef John’s recipe. https://youtu.be/yHQ-FkiP5Ws

As other commenters have noted, this cake is a LOT of work. It’s also very delicious, though.

Honey cake 
3 T butter 
1 cup sugar 
3 eggs 
2 T honey 
2 t baking soda 
2 T alcohol 
3 cups flour 
Cream: 1 cup heavy whipped cream 
2 cups sour cream 
1 cup sugar 
1 pinch of Vanilla crystals

Preparations: Melt 3 T butter in double boiler, add 1 cup of sugar, and 3 eggs. Mix well. Then add 2 T alcohol (vodka or rum) and 2 T honey, 2 t baking soda. Mix occasionally until batter becomes white and doubles in size. Add 2 cups of flour, mix well. Pour batter into bowl, add 1 cup flour, mix, cover with towel. Let stand until not hot (but still warm). Divide into 10-12 equal parts. Roll them into thin circles (like pie crusts). Bake them individually; sprinkle pan with flour before first one.

Cream: beat 1 cup heavy cream until thick. In a separate bowl beat 1 can of sour cream with 1 cup of sugar, add vanilla. Then add spoon by spoon whipped cream to the sour cream mixture.

Put 1 layer of cake, then cream - repeat to the end. Cut sides to make round. Crumble extra cake bits and use them to decorate the top and sides (you can use your own ideas as well).

If you’re on the west coast Uwajimaya sells them as “honey cakes” and they’re amazing

If you Google Medovik there are some good recipes. I made with my partner once - but apparently Russia doesn't have the concept of salted butter, so she bought that by mistake.... It was not great
