Cherry cake in the snow

From these products at room temperature, knead the dough. To do this: rub the butter with sour cream until smooth. Sugar does not go into this dough. If there is no desire to experiment, then add 2 tablespoons of sugar at this stage (this does not need to be done in the original recipe).
Extinguish the soda in vinegar, add to the dough. Here is the flour with vanilla, mix. As a result, the dough will easily lag behind the hands. Wrap it in clingfilm and refrigerate for 2 hours.
For the filling: put the pitted cherries in a colander and leave to drain for 2 hours. Stir from time to time. At the end, lightly press down the cherry with a spoon to squeeze out the rest of the juice.
Divide the finished dough into 16 parts. Roll out each part into a strip. Sprinkle brown sugar in the center. Put the cherries on top of the sugar and sprinkle with sugar again. Pinch the dough strips, like dumplings, along the entire length. The tubes will turn out.
In a detachable form, line the parchment, greased with oil. At the bottom, lay out tubes with cherries in circles with seams on the side. There should be 1 layer. Press it down slightly from above so that it is uniform. As a result, we will get 3 cakes made of tubes with cherries. Bake every 20 minutes at 200C. Let the cakes cool on the parchment so that they do not fall apart.
For cream: beat sour cream with powdered sugar until fluffy.
Each cake should be smeared with cream and put on top of each other. And put the third cake on top, bottom up, so the cake will turn out smoother. Coat the cake with cream and sprinkle with coconut chips.
