In a large mixing bowl, cream together the softened butter and brown sugar until light and fluffy. Then, add the egg and mix until well combined.

In a separate bowl, whisk together all the dry ingredients including flour, baking powder, salt, and the spices.

Gradually add the dry ingredients to the wet mixture, stirring until the dough forms. It should be soft but not sticky.

Scoop out tablespoon-sized portions of the dough and shape them into small balls. Place them on a piece of parchment paper.

Pour 1.5 cups of water into your pressure cooker and place the parchment paper with the cookie dough balls on a steaming rack. Close the lid securely.

Set your pressure cooker to manual mode for 10 minutes. Once the timer goes off, allow for natural pressure release for 5 minutes before manually releasing any remaining pressure.

Carefully remove the rack and let the cookies cool on a wire rack before serving.
