Rim two martini glasses with a lemon wedge, then dip in cinnamon sugar to coat.
Fill a cocktail shaker with ice. Add apple cider, vodka, brandy, lemon juice and maple syrup; shake until well chilled.
Strain into the prepared martini glasses, garnish with apple slices and serve.
Notes
Substitutions: You can substitute the maple syrup for honey or simple syrup. Use a fresh apple slice or cinnamon stick for garnish. You can make a larger batch by 3x, 4x or 5x this recipe. Stir together all of the ingredients in a large pitcher and store in the refrigerator until ready to serve. This will make 6-10 servings.
