Step-by-Step Procedure

Step 1: Preparation of the Base

1. Mix eggs and sugar: In a bowl, beat 3 whole eggs with the icing sugar until well combined.
2. Add dry ingredients and vanilla: Add the flour, baking powder, and vanilla extract to the egg mixture.
3. Incorporate cold butter: Work in the cold butter with your hands until the mixture resembles coarse crumbs.
4. Knead the dough: Add the egg yolks and knead until you obtain a smooth dough.

Step 2: Resting the Dough

5. Refrigerate part of the dough: Put 1/3 of the dough in the refrigerator.
6. Roll out the dough: Roll out the remaining dough on a baking tray lined with baking paper to form the base.

Step 3: Filling Preparation

7. Mix filling ingredients: In a bowl, mix together the sour cream, yogurt, half of the sugar, and cornstarch.

Step 4: Whip the Egg Whites

8. Beat egg whites: In a separate bowl, whip the egg whites with a pinch of salt until soft peaks form.
9. Add remaining sugar: Gradually add the remaining sugar to the egg whites and continue beating until stiff peaks form.

Step 5: Assembly

10. Combine egg whites with filling: Gently fold the whipped egg whites into the yogurt mixture.
11. Pour filling over base: Pour the combined filling onto the dough base in the pan.
12. Crumble reserved dough: Crumble the reserved cold dough over the top of the filling.

Step 6: Baking

13. Bake: Preheat your oven to 180°C (350°F). Bake the cake for 40-50 minutes, or until the top is golden and the filling is set.

Step 7: Cooling

14. Cool the cake: Let the cake cool completely before serving to allow the filling to set properly.
