Everyone sees massive round blue tins full of butter cookies around the holidays. Then it takes us until February to eat them all. Royal Dansk, maker of the best holiday butter cookies, has attempted many designs over the years. The current lineup, evolved through years of research, intends to represent the most appealing set of butter cookie designs for the most general demographic.
This is a few years old, but it's a classic. Only Marco could examine a simple tin of cookies in such detail. I personally love them all, but the pretzels are the best.
