Incorporate (without beating) 2 eggs + 1 cup sugar + 7 oz grated coconut (you can use 1/2 grated coconut and 1/2 coconut slices). It is easier to incorporate everything with a wire whisk.
Add 4 oz melted butter and mix thoroughly. Add 3/4 cup all-purpose flour and mix with a spatula. Pour the mixture into an oiled square mold, preferably with a baking sheet. It is a really thick batter, do not panic, you are doing fine. Add 10.5 oz blueberries (gently crushed) on top of the batter.
Bake at 370°F for 30 minutes. And done.
