In medium sized bowl, mix butter, cream cheese, sugar, and salt to be light and fluffy. Add egg and vanilla extract.

Reduce the speed and add flour and baking powder. Mix for 30 seconds just to make the ingredients combine.

Cover the bowl and rest in the fridge for at least 1 hour.

Preheat the oven to 190 C / 374 F, 20 minutes before baking and cover cookie baking pan with parchment paper.

In shallow bowl, combine coating ingredients.

Take the dough out and divide to 28 same sized pieces, if possible.

Form the balls using the palms of your hands, roll each one in the coating and place on parchment paper. Make sure each ball has 2 inches of space to spread during baking.

Bake for 12 minutes or until each cookie gets golden colour on the edges. Cool completely and place on serving plate or in airtight container.
