Combine flour, baking powder, sugar and coconut in a large bowl. Stir in melted butter and mix well. Press into the base of a greased and lined 20cm × 30cm baking tin. Cook in a preheated 180 °C oven for 15 minutes or until firm.
To prepare the topping, place the NESTLÉ Sweetened Condensed Milk , butter, dates and golden syrup in a small heavy based saucepan. Cook gently, stirring constantly until mixture turns golden brown.
Spread topping over base, sprinkle over pistachio nuts and return the baking tin to the oven for a further 10 minutes, until golden. Cool in the tin before cutting into fingers.
