Using a cocktail shaker, combine vodka, apple cider, and lime juice. Shake until well mixed.
Fill 2 copper mugs ¾ of the way full with crushed ice, then divide cocktail mixture between mugs. Top off each mug with chilled ginger beer, filling to top.
Top with a sprinkle of cinnamon. Garnish with cinnamon sticks and an apple slice. Serve and enjoy!
