Preheat the oven to 180°C (356°F). Ensure the egg and butter are at room temperature.

In a bowl, combine flour, baking soda, baking powder, and salt. Mix well with a whisk.

In a separate large bowl, beat the butter until creamy and slightly fluffy.

Add sugar to the butter and continue beating until the mixture is smooth and grain-free.

Add the egg and vanilla extract to the butter mixture. Beat for 1-1.5 minutes until combined.

Gradually add the dry ingredients to the wet mixture. Fold gently using a spatula.

Add white chocolate chips and coconut flakes to the dough. Mix until evenly distributed.

Divide the dough into 15 equal portions (about 2 tablespoons each) and roll into balls. Place on a baking sheet.

Bake in the preheated oven for 13-15 minutes until the edges turn golden brown.
