Measure the butter into a mixing bowl. Sieve the powdered sugar into the bowl and whisk together until light and fluffy, about 2 to 3 minutes.
In a separate bowl, sieve the all-purpose flour and rice flour together. Add the salt and baking powder and mix. Add the roasted cumin seeds.
Add the dry ingredients to the creamed butter and sugar. Mix to form a soft dough.
Pinch off small portions of dough, roll into balls, and press gently to flatten.
Arrange on a greased baking tray.
Preheat the oven to 180°C (350°F) for 10 minutes.
Bake for 10 to 12 minutes until the edges are lightly golden.
Remove from the oven and cool completely on the tray before transferring to an airtight container.
Serve with a hot cup of chai and enjoy.
