Pure pumpkin puree and real maple syrup taste better than flavored syrups. Add more cinnamon or nutmeg if you want a bigger spice kick. Adjust sweetness with more or less maple syrup or sparkling water. For a creamy twist, swirl whipped cream directly into the drink. Leftover pumpkin puree keeps in the fridge for about a week. This mocktail is caffeine-free and a fun option for fall parties.
