Beat the eggs with sugar for 2-3 minutes

Add the butter and sour cream mixed with baking soda, beat for a couple more seconds until smooth, then gradually incorporate the flour to knead the dough

Chill the dough in the refrigerator for 20 minutes

Then divide the dough into 8 portions and roll each portion into a thin sheet

Roll out directly on parchment paper, transfer to a baking sheet, dock the sheet with a fork, and bake at 200°C (approx. 400°F) for about 5-7 minutes

For the frosting, whip the butter with vanilla until fluffy and pale

Gradually add the condensed milk while continuing to whip
