I found a recipe and altered it a bit -whole wheat and splenda :) Super easy though.

2 c. whole wheat flour
1/2 c. butter or margarine
1/4 c. brown sugar
3 eggs, well beaten
2 c. splenda
1/2 tsp salt
1 c. shredded coconut
1/2 c. raisins
2 tbsp lemon juice
1 tsp lemon zest

Heat oven to 350 degrees F.
Mix flour, butter, and 1/4 c. sugar and press mixture firmly into bottom of lightly greased 9x13" pan.
Bake 10 mins.
Mix eggs, splenda, and salt together. Stir in the remaining ingredients and spread over the partially baked bottom layer.
Bake 25 mins or until top is lightly brown.
