Non-mezonot dessert foods (which often have a sweet taste) are not normally eaten with bread. Say fore-blessings on desserts at a meal (for which you have already said ha'motzi and eaten bread) only on:

• Fruit from “trees”(borei pri ha'eitz),
• Fruit from the ground (borei pri ha'adama), such as melons and strawberries, and
• Specialty items (she'hakol), such as ice cream.
