What To Consider Before Substituting Liquid Sweetener For Sugar, According To An Expert - Tasting Table
Briefly

Baking is an exact science, making precision crucial for successful outcomes. Substituting sugar with liquid sweeteners can disrupt recipes due to differing weights and volumes. Liquid sweeteners, like agave syrup, can introduce excessive moisture, resulting in undesirable batter consistency. Other sweeteners can impact flavor profiles significantly, with strong flavors like honey overshadowing delicate tastes. Experimenting with liquid sweeteners requires caution and small adjustments to avoid adversely affecting texture and flavor in baked goods.
Substituting sugar with liquid sweeteners can seriously throw off the ratio, and these ingredients vary drastically in weight and volume, so they can't be substituted 1:1.
Using agave syrup in place of sugar adds a significant amount of moisture to your recipe, which results in a more liquidy batter or dough.
In addition, many liquid sweeteners actually carry a notably different sweetness level or flavor, for example, honey can be a very strong flavor if used as the only sweetener.
If your baked good is chock-full of delicate flavors, its subtle, nuanced notes might be muted by an overpowering liquid sugar like maple syrup or molasses.
