Polish chocolate & walnut cake (Polish Dessert)

Heat the oven to 170C/150C fan/gas 3½. Line a 30 x 22cm shallow baking tin with baking paper. Sift the flour and mix it with the cocoa, then set aside. Beat the egg whites until stiff and then add the sugar in small batches. Add the egg yolks, one by one, beating constantly. Pour in the flour mixture and gently fold everything together with a spatula. Pour the prepared batter into the lined pan and bake for 35 minutes. Let cool for 5 minutes, remove from the tin and line the tin again with baking paper.

step 2
To make the meringue, beat the egg whites until stiff and then gradually add the sugar, a tablespoon at a time. When we have a stiff and shiny meringue, add the finely chopped walnuts, flour and yeast. Spread the mixture in the lined mold and cook for 40 minutes on the same heat. Remove from the oven and let cool.

step 3
For the chocolate glaze, heat the cream over low heat, then remove from the heat, pour in the chopped chocolate and mix until melted and shiny.

step 4
Cut the cooled chocolate cake and meringue into two layers. Put the walnut meringue on top of the bottom layer of cake and sprinkle with some of the reserved walnuts. Add another layer of meringue and then the top layer of chocolate cake and cover the top with chocolate frosting. Decorate with nuts. Place the finished cake in the refrigerator for 1-2 hours before serving.
