Honey (Best Option)
Use 3/4 cup honey for every 1 cup agave syrupHoney works well as a substitute because it shares a similar sugar composition and hygroscopic properties with agave syrup, helping retain moisture and tenderness in sugar cookies. Its natural sugars caramelize during baking, contributing to a golden color and subtle flavor enhancement.
When substituting, reduce the amount to about 75% of the agave volume due to honey's higher sweetness and viscosity. Also, slightly reduce other liquids in the recipe if the dough feels too wet. Watch for faster browning during baking.
The final cookies will have a slightly more pronounced floral sweetness and a tender crumb similar to the original, with a slightly deeper color.
