The Fruity, Sweet Hit
Small candies such as Reese's Pieces or toffee bits are always winners, but if you like a more subtle sweetness, consider chunks of dried fruit, like apricot or cranberry, or candied versions, such as ginger or orange. Flakes of sweetened coconut are fantastic too. You can even put fresh fruit in brownies: Pour half the batter in the pan, stud it with raspberries or pitted cherries, and cover with the remaining batter. Again, 1 cup is a good ballpark amount.
