Honey (Best Option)
3/4 cup honey per 1 cup agave nectarHoney works well because it is a natural liquid sweetener with similar viscosity and moisture content to agave nectar, which helps preserve the cake's moist texture. It also contains fructose and glucose, which contribute to browning and flavor development during baking.
To ensure success, reduce other liquids in the recipe by about 2 tablespoons per cup of honey used to avoid excess moisture. Also, honey can brown faster, so monitor baking times closely to prevent over-browning.
The final carrot cake will have a slightly richer flavor and a golden color, with a moist crumb comparable to the original agave-sweetened version.
