Preheat oven to 160 degrees Celsius. Line two cookie sheets with parchment paper and set aside. Toast the half cup dessicated coconut until slightly brown and set aside
Beat butter and sugar until creamy. Mix in vanilla essence
Add the baking powder and flour and combine. Mix in the 3/4 cup dessicated coconut. You should have a soft dough
Take a tablespoon of cookie dough and roll into a ball. Place them on the cookie sheet and flatten them with the back of a measuring cup. Press them down as thin as you prefer. The edges may crack a little but that's ok. Ensure there is enough space between each cookie as you don't want them to stick together.
Sprinkle the toasted coconut on top of each cookie and press it down a little with your fingertips
Bake at 160 degrees Celsius for 12-15 minutes until slightly brown and crisp. They will be soft when out the oven but will harden when cool
Cool the cookies on a wire rack
Notes
I always reduce the sugar in my cookies considerably. You can increase the amount of sugar if you prefer
The brown sugar adds a little chewiness to the cookies. However, if you don't have any you can use just white sugar. However, the texture will not be exactly the same.
I've added 3/4 cup of sugar and dessicated coconut because I wanted a soft dough to make my cookies thin. If you want thicker cookies you can increase the amount of flour and coconut by another 1/4 cup each. You won't be able to flatten your cookies as much because the dough won't be as soft, resulting in slightly thicker cookies
