Use Fruit to Replace Sugar
Instead of using white sugar, brown sugar, maple syrup, honey, or other sweeteners in recipes, use the natural sweetness of fruit — it'll also offer the added benefit of fiber and vitamins. Experiment with using mashed banana, applesauce, puréed berries, and grated apple in your baked goods. These deliciously sweet muffins are made with strawberries, apples, and grapes and no added sugar.
Stahl also suggests using spices such as cinnamon, nutmeg, and vanilla to add sweetness. And if you can't live without sugar, recipes will often taste just fine if you use half the amount suggested. Ferrari said you can also use zero-calorie, no-sugar Swerve or stevia in your baked goods.
