Whisk the millet flour, wheat flour, and powdered palm sugar together.

Add softened butter and stir until smooth.

The milk can be added to soften the dough, but take care not to add too much, as the dough may become runny.

Roll the dough into small, equal sized balls; flatten with the palm of your hand.

Add cookies to prepared baking sheet.
