My sister gave me a recipe where they were quite floury. They tasted good but the floury feeling bothered me, so after some trial and error I finally came up with this.
My sister is also satisfied with this taste. When I distribute these cookies with tea to relatives, they disappear in no time.
Since everybody always asks if I bought these, I decided to post the recipe here. Please try them.

You can leave the butter out to bring to room temperature or you can heat it up in the microwave to melt it.
After that, just mix.
You don't even have to sift the powdered ingredients. Just mix until the it's no longer powdery.
Then it's just forming into whatever size balls you want. But if they are too big, you need to change the baking time.
Try to make them all the same size as much as you can please.
If you try to coat them with powdered sugar before cooling them, the sugar will melt and since the cookies are soft, they will fall apart easier. So make sure to cool completely before coating with sugar. Recipe by Maimama
