I came up with these when I was feeling a little hungry one afternoon.
Add vanilla extract for fragrance. I recommend you use caster sugar. Recipe by *Halu*
If you increase the amount of butter to 40 g, they'll be moist. They'll also still be sweet with just 40 g of sugar.
Soften the butter to room temperature and mix it with the sugar.
Add the beaten egg a little at a time, mixing with each addition. Mix in the dry ingredients.
Fill the cups 60-70% of the way, and bake for 15 minutes in the oven at 180ºC.
