Preheat oven to 350 degrees F. Combine 1 cup of the flour and 1/4 cup
of the brown sugar, add butter and blend well. Press firmly into a 9 inch square baking pan and bake for 15 minutes. Meanwhile, beat the eggs until thick and light yellow. Gradually add the 1 cup of remaining brown sugar, beating until mixture is light and fluffy. In a separate bowl mix together the remaining 1/4 of the flour and the baking powder, gently stir into the egg mixture. Add the coconut, vanilla and nuts. Spread over the baked crust in the pan, and bake for 20 to 25 minutes or until lightly browned. Cool and cut into squares.
