Recipe by: JOY OF COOKING-1943 Preheat oven to 150ºC . Melt butter and chocolate in the top of a double boiler. Cool slightly. Add sugar and egss. Mix flour, baking powder and salt , then add to the butter mixture alternately with milk. Add vanilla. Mix in pecan pieces. Grease a 9 inchx13 inch baking pan and dust lightly with cocoa ( makes cake look and taste better than dusting with flour when you're doing chocolate cake). Scrape batter into pan ( Batter is stiff). Bake at 150ºC for 10 minutes, then raise temperature to 180ºC and bake 20 minutes longer. DO NOT OVERCOOK. When the cake is moving slightly away for the sides of the pan it is done. Allow to cool for about 20 minutes on a wire rack before you try to cut it, or it will just crumble. Cut into squares and serve. ----
