Chocolate Crinkles

Mine wasn't crinkled at all, so I found out that you should put your tray at the top part of your oven. >_<



170g dark chocolate
85g butter
185g all purpose flour, sifted
3 tbsp cocoa powder
3/4 tsp baking powder, sifted
115g sugar
2 eggs
1 tsp vanilla
1/2 tsp salt

1. Melt chocolate with butter using the microwave or double-boiling.
2. Beat sugar and eggs until thick and smooth. Add vanilla and melted chocolate. Mix until combined. Add the flour, cocoa mixture and salt, mix till just combined.
3. Scoop dough out into a plastic container with a tight-fitting lid, cover and refrigerate for at least 2 hours.
4. Grease baking tin, roll dough into a 1 inch balls and place about 3 cm apart. Place unused dough back in the fridge.
5. Place tray at the second from the top of the oven rack. Bake in a preheated oven at 170 degree C for 15 minutes. Let cookies cool for 5 minutes before transferring them to the cooling rack.
