Preheat Oven: Set your oven to 180°C and line a baking tray with parchment paper.
Mix Dry Ingredients: In a large bowl, combine the plain flour, baking powder, brown sugar, and white sugar. Mix well until evenly distributed.
Prepare Wet Ingredients: In a separate bowl, whisk together the egg and vanilla essence until combined.
Combine Wet and Dry Ingredients: Pour the whisked egg mixture into the dry ingredients. Add the melted butter and stir until the mixture is well incorporated.
Cool the Dough: Allow the dough to cool slightly. This will prevent the chocolate chips from melting when added.
Add Chocolate Chips: Once the dough has cooled, fold in the chocolate chips until evenly distributed throughout the dough.
Shape and Bake: Using a spoon, drop tablespoon-sized portions of dough onto the prepared baking tray, spacing them about 2 inches apart.
Bake: Place the tray in the preheated oven and bake for approximately 15 minutes, or until the cookies are golden brown around the edges.
Cool and Serve: Allow the cookies to cool on the baking tray for a few minutes before transferring them to a wire rack to cool completely. Enjoy!
