Use only food-grade, culinary eucalyptus leaves and avoid oversteeping or using too large a quantity, as the flavor can quickly become overpowering and medicinal; aim for a subtle cooling, herbal note that complements sweetness rather than dominates it. Taste the infused milk before adding it to the batter and frosting—if it’s very strong, dilute with a little plain milk. Always let the cupcakes cool fully to prevent the frosting from melting and sliding off, and chill the frosting briefly if it seems too soft to pipe. These cupcakes taste best the day they’re made, but you can refrigerate them in an airtight container for up to two days, letting them come to room temperature for 20–30 minutes before serving for the best texture and flavor.
