Break the eggs into a bowl, add the sugar and whisk until a fluffy light mass.
Add the sifted flour and gently mix until smooth.
Cover the baking sheet with baking paper and pour out the dough, flatten. Bake in a hot oven at t=180 degrees for 15 minutes, until ready. Remove, cool and remove the paper.
Align the edges and cut into 3-4 parts. I cut it into 3.
Beat the butter until fluffy. The mixer helps me with this very well.
Add the halva, condensed milk, yolk and powdered sugar to the butter and mix.
Whisk everything to a fluffy mass.
Make 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 cool. We impregnate all parts of the biscuit with syrup.
Smear the cream on each layer and collect the cake. Cover the sides and top with cream, align.
For the glaze, put the butter in a pan, pour the milk and put it on the fire. Add the cocoa and mix the sugar. Bring to a boil, remove and completely cool.
Cover the cake with icing on all sides.
Decorate at your own discretion. I have walnuts on the sides and candied fruit on top.
