I was curious too so I googled it. This is what I found:
This treat, found in Epcots Norway pavilion at Kringla Bakeri og Cafe, is actually pretty simple. A sweet bread roll is injected with vanilla pudding or custard, then covered with sweet icing and toasted coconut. The School Bread recipe comes from a classic Norwegian snack (properly titled Skolebrød), which kids took to school in their packed lunches or parents sold at bake sales.
