I assume pfeffernüsse must be pretty much the same as peppernøtter in Norway. Soon as I get home from work I'll post a recipe for that, if you like. We've got 6 dozen or so maturing in tins waiting for Christmas. In Norway you're supposed to bake large batches of 7 different kinds of cookies for Christmas. You end up eating cookies with your coffee way past spring and in Norway you drink a lot of coffee. I corrupt the tradition by baking a large batch of chocolate chip cookies, very un-norsk.
Fruit cake in Norway, called "julekake" or Christmas cake, sounds alot like stollen, maybe even less rich. A light sweet bread with raisins and candied fruit in small quantities. Eaten in buttered slices with jam or that caramelly wheycheese "geitost", made from the whey of goat's milk, or a combination of goat's milk and cow milk. If you think peanut butter sticks to the roof of your mouth, try eating "geitost".
