Nutty Wholewheat Triangles

I've been looking for a good recipe for peanut cookies for a while, but the only ones I could find online used peanut butter. While I have nothing against peanut butter, I think they are much better spread on toast than beaten into a batter. Finally, I made up a recipe myself, and was really satisfied with the result.
The triangles are slightly fragile and collapse gently if you squeeze them too hard, but they are absolutely melt in the mouth!!!

1/4 cup roasted peanuts- crushed
1/4 cup desiccated coconut
1/2 cup sugar- ground coarsely
1 cup wholewheat flour
1/4 cup olive oil
1/2 tsp baking powder

Method:
Grind the peanuts and keep aside (I like it fine ground, but you can leave a few chunky pieces too)
Grind the sugar and keep aside
Sieve together the flour, powdered sugar and baking powder.
Add the ground peanuts and desiccated coconut and mix well
Make a depression in the centre, pour in the oil, and knead well.
Grease a baking sheet, and spread the dough evenly across it.
Meanwhile, pre-heat the oven to 180 degrees.
Place a container with water in the bottom rack, and the cookie tray in the middle rack.
Bake for 10 minutes, take out, and with a sharp knife, make a cut for 16 squares, and further cut each diagonally (32 triangles in all). Return to the oven and bake for a further 5 minutes (checking every minute after 13 minutes, to ensure it doesn't burn).
Remove, let it cook, and break along the cut lines.
