Combine maida, milk powder, and baking powder in a bowl.

In a separate bowl, cream together softened butter, sugar, and vanilla extract.

Add the dry ingredients to the butter mixture and mix until a dough forms.

Preheat oven to 350°F (175°C).

Roll out the dough and use a moon-shaped cookie cutter to cut out biscuits.

Arrange the biscuits on a baking tray.

Bake for 15 minutes, or until lightly golden.

Cool completely before serving.
