If you enjoy a sugared glass, prep the rim of your glass by rubbing a lime wedge along the rim. Dip into your favorite calorie-free sweetener, and set aside.
Make the marg:
Fill a cocktail shaker with ice. Add tequila, orange juice, and pumpkin spice. Shake well until the sides are fully frosted.
Serve:
Pour the skinny margarita into the prepared glass, top off with sparkling water, to make it a taller cocktail. Garnish with cinnamon sticks. Enjoy!
Notes
Make it a pitcher that serves 8 by combining 1 ½ cups tequila, 2 cups orange juice, 8 pumps sugar-free pumpkin syrup, and 1 ½ teaspoons of pumpkin spice with a handful of ice in a pitcher. I give it a stir and refrigerate it for one hour. Serve over ice, top it off with sparkling water (for a taller drink), and garnish.
