1 cup butter, softened
1 cup brown sugar
1 egg yolk
1 cup unbleached flour
6 (1.05 oz.) milk chocolate bars, grated ( I used 7 oz. semi-sweet mini chocolate chips)
2/3 cup chopped pecans
Preheat oven to 350 degrees
In a medium mixing bowl, cream butter, sugar, and egg yolk until very smooth. Gradually add flour until well blended. Spread dough on lightly greased 15 1/2″x10 1/2″x 1″ sheet pan. Bake for 15 to 20 minutes until medium brown. Sprinkle chocolate shavings or chips evenly over cake. Put in oven to melt and when warmed remove from oven and spread over top. Sprinkle with nuts. Cut into squares when cool.
