Preheat your oven to 350°F (175°C) and grease a baking pan.

In a medium bowl, whisk together flour, Nokcha powder, baking powder, and salt.

In a large mixing bowl, cream the softened butter and sugar until fluffy. Add eggs one at a time, mixing well after each addition.

Gradually incorporate the dry mixture into the wet ingredients, alternating with milk until fully combined.

Pour the batter into the prepared pan and smooth the surface.

Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. Allow to cool before slicing.
