Some sweet liquors taste amazing, but the syrupy addition can contribute to extra unnecessary calories. Bri Bell, registered dietitian and owner of Frugal Minimalist Kitchen, explained that you should "cut back on sugar by skipping syrupy liqueurs and instead opt for the real flavours. Instead of peppermint schnapps, use peppermint infused vodka or real mint leaves. Instead of coffee liqueur, use a shot of espresso."
