Death by White Chocolate Cookies

1 package (8 squares) semi-sweet baking chocolate
3/4 cup firmly-packed brown sugar
1/4 cup (1/2 stick) butter or margarine
2 eggs
1 teaspoon vanilla extract
1/2 cup all-purpose flour
1/4 teaspoon baking powder
6 squares Premium white baking chocolate, coarsely chopped
2 cups chopped macadamia nuts or slivered almonds

Note: If not using nuts, increase the flour to 3/4 cup.

Preheat oven to 350 degrees F.

Melt semi-sweet chocolate in double boiler (or microwave for 2 minutes). Stir until chocolate is melted and smooth. Stir in sugar, butter, eggs and vanilla extract with a wooden spoon until well blended. Stir in flour and baking powder. Stir in white chocolate and nuts. Drop mixture by scant 1/4 cupsful onto ungreased cookie sheet. Bake about 13 minutes, until they are "puffed" and feel set. Cool for 1 minute then remove from cookie sheet. Cool completely.
