I followed the directions on a box of Pillsbury Hot Roll Mix and simply added 1/4 cup sugar and 1 cup chopped fruit bits during mixing. They taste delicious, but I realized after the fact that 1/2 teaspoon each of nutmeg and cinnamon would make them perfect (next time!). I made the icing from 1 cup of powered sugar mixed with a few tablespoons of hot water.
The box made 18 hot cross buns...and we've already eaten 6! Happy Easter.
