Preheat oven to 350°F. Line 2 baking sheets with parchment paper or lightly grease them.
Combine flour, baking powder, black pepper, cumin seeds and salt. Mix well.
Make a well in the middle of the flour mixture and add oil. Mix until the mixture is crumbly.
Now add milk 1tbsp at a time and mix until the mixture starts to come together. When you squeeze the flour mixture in your hand it should hold its shape.
Make lemon size balls and flatten the cookies. Place them on the prepared baking sheet about 1" apart.
Bake for 10~15 minutes or until the cookies are lightly browned around the edges.
Cool on wire rack. Once cooled store them in airtight container.
