Beat the eggs with the sugar until increase in 2 times.
Add cream, sour cream, lemon zest and liqueur. Knead a homogeneous mass.
Add the sifted flour with baking powder. Knead the dough evenly.
Finely chop the nuts.
Halvah cut into medium cubes. On its taste of I did with sesame halva, but can be any.
Chopped nuts and halva pour into the dough and gently, by hand, mix with a spoon.
Pour the dough into a mold and bake at 180 degrees for 40-45 minutes.
Allow the cake to cool slightly in the form of 15-20 minutes, then gently remove.
Hot removed very bad, the dough is so tender and crumbly that there is a chance to remove it in parts ))))) I hurried, and I have one side a little collapsed. That's why I only show half.
Sprinkle the cooled cake with powdered sugar. To cover with glaze or something else I considered superfluous, because it is already saturated with flavoring additives, the rest is simply superfluous.
