First step - put your butter in a pot and let it melt. Keep in on medium until it's fully melted and starts to froth up - it should have that nutty smell to it, like the first stage of caramel. This step is important - do not just throw the butter in the microwave. Lazy! You want that nuttiness from the butter almost burning.

Now - mix the butter (after it's been removed from the heat for about 7 minutes) with the sugars.

Then, mix in the eggs, vanilla and yogurt. Add the rest of the ingredients (slowly, of course) and ensure it's well mixed. Put in the fridge for 6 hours.

Once the 6 hours have passed, it's time to roll some dough!

Roll out in little balls - about 1 1/2 tablespoons - 2 tablespoons. Roll in the rolling mixture and place on a baking sheet about 2-3 inches apart.

Bake at 350 degrees for 10 minutes. Take out and let cool. Let them cool for about 6 minutes before trying to remove them from the pan - they are fragile.
