I have always found these walnut lemon bars quite elegant and with a delicate flavor combination. Pairing chocolate with lemon and walnuts is by far one of the best combinations. These bars are made with a dense walnut layer at the bottom followed by a lemony creamy layer in the middle and topped with chocolate ganache.
Preheat the oven to 350F (180C). Slightly grease a 8×8 inch (20x20cm) square pan and line with parchment paper, in such a way that some edges overhang to make it easy to lift it up once it's set.
In a large bowl, cream together butter and sugar until creamy. Add walnuts, lemon zest and flour and mix well.
Separate egg yolks from egg whites. Whip egg whites with salt until foamy. Gradually add 2 tbsp of sugar and whip until stiff peaks. Fold in egg whites into walnut mixture.
Pour the batter into prepared pan and bake for 15 minutes.
Prepare the lemon layer.
Meanwhile mix egg yolks with sugar and lemon zest until thick, creamy and pale yellow colored.
Remove the walnut base from the oven and add yolks mixture on top of the cake and bake for another 10-15 minutes. Let it cool.
Prepare the chocolate ganache.
Heat the cream in a small saucepan. When the cream just begins to boil at the edges, remove from heat and pour over the chopped chocolate. Let sit one minute, then stir until smooth.
Spread the chocolate ganache on top of the cake. Let it set before serving.
