Break the eggs into a bowl, add sugar and whisk until a fluffy light mass is obtained.
Add the sifted flour and mix gently until smooth.
Cover the baking sheet with baking paper and pour out the dough, smooth it out. Bake in a hot oven at t = 180 degrees for 15 minutes, until cooked. Remove, cool and remove the paper.
Align the edges and cut into 3-4 pieces. I cut it into 3 parts.
Beat the butter until fluffy. The mixer helps me in this very well.
Add halva, condensed milk, yolk and powdered sugar to the butter and mix.
Whisk everything until you get a fluffy mass.
Make the impregnation. To do this, pour water into a saucepan, add sugar, bring to a boil and cook for 1 minute. Remove from the heat and pour in the cognac. Close and refrigerate. We impregnate all parts of the biscuit with syrup.
Spread the cream on each layer and assemble the cake. Lubricate the sides and top with cream, align.
For the glaze, put the butter in a frying pan, pour in the milk and put it on the fire. Add cocoa and mix with sugar. Bring to a boil, remove and cool completely.
Cover the cake with icing on all sides.
Decorate as you wish. I have walnuts on the sides, and candied fruits on top.
