Oreh Keyk or Walnut Bar Cake

Walnuts abound here in Bulgaria & are lovely much better than the shop bought variety!!! I have a huge tree along with a few smaller ones so plenty of nuts available, this year though the crop has been bad I have only managed a few kilo's along with every other tree in the area. Thank goodness last years was bountifull & I am still using them in my baking. The Bulgarian's use Walnuts in many traditional recipes & it is a protected tree you can't chop them down.
This is a really nice bar type cake, in fact it's not a cake at all. Small squares or bars are the best way to cut it.
I make this with the walnuts from my tree, last years crop.

7oz Walnuts coarsely chopped
8oz Butter/Margarine
10oz granulated sugar
11oz Plain flour

Pinch salt

1 Egg separated

1tsp Vanilla extract
Pre heat oven to 180c, 160c if fan
Chop all the walnuts
Butter a cake pan I use a square one as its easier to cut in bars
Beat butter & sugar together till it is creamed. Mix in the flour salt vanilla extract & egg yolk till it is well mixed or blended. Mix the walnuts into the mixture making sure they are well mixed throughout.
Pour into a greased tin , level & press down firmly. Brush the top with the egg white if you wish
Bake in the oven for 30 minuets, check its cooked with a tooth pick if not dry continue for 5 minuets etc
Cooking time depends on how deep the mixture is so related to your tin size
Turn out to cool & cut into bars while warm, not hot!
