Combine all ingredients except for the vodka and whipped cream in a large saucepan. Over medium high heat, bring to a light simmer for 15 minutes. Strain and serve warm. If you want to make this a cocktail, add 1 oz of vodka to your 8 oz glass of cider. Top with whipped cream, caramel drizzle, cinnamon stick, and a rosemary sprig. Enjoy!
