Most US cake mixes ask for 2 or 3 eggs.
This frosting is a caramel based prepared frosting that has coconut (maybe 4 ounces?) and pecans (about the same) chopped in it. You could make the same idea with a boiled frosting of butter and brown sugar and adding coconut and pecans.
A bundt pan is a 10 cup shaped pan with a hole in the middle, similar to an angel food pan but has decorative scallops instead of straight sides. I'm guessing the hole in the middle keeps the cake from overcooking.
