Congo Bars

I have way too many cook books yet I've only ever followed a handful of recipes from them.  This is one of the handful.

This is a recipe from The Great Book of Chocolate by David Lebovitz, though he got this recipe from Flor Braker.

Of all the great recipes from this amazing book, I had decided to go for the seemingly easiest first.  I had never had congo bars, admittedly the name got me, I thought it'd be more exotic.  It's something like a cross between a brownie and a chocolate chip cookie... that kind of tastes like a biscotti as well.  It's good. 

Ingredients
150g unsalted butter, melted and cooled
450g light brown sugar
3 large eggs
285g flour
2 1/1 tsp baking powder
1/2 tsp salt
300g dark chocolate chunks
150g mixture of toasted walnuts and almond flakes

Method
Preheat oven to 160C.  Grease a large baking pan.

Mix the butter, sugar and eggs until well incorporated.  In another bowl, sift together the flour, baking powder and salt, then mix this mixture into the wet mixture and fold in the chocolate and nuts.

Spread the batter into the greased baking pan as evenly as possible and bake for about 30 minutes or until golden.  When cool, cut into bars or small squares and leave overnight before you eat them.
