If you are a chocolate lover, you
MUST get the Chocolate Thunder. It is a large donut, filled with chocolate cream, topped with a chocolate gnache and chocolate sprinkles.
If you prefer vanalia, you should get the White Lightning. It's the same as the Chocoloate Thunder, but with vanalia flavored cream, glaze, and sprinkles.
