Step 1: Prepare the spiced apple base. In a small saucepan, gently warm the apple cider (if using alcohol, add it now) with cinnamon and nutmeg over medium-low heat for 2-3 minutes. Remove from heat and let it cool completely.
Step 2: Make the cream cheese topping. In a medium bowl, beat the softened cream cheese with powdered sugar and vanilla extract until smooth and creamy.
Step 3: Whip the heavy cream in a separate bowl until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture until just combined and airy.
Step 4: Assemble the shots. Pour about 1.5-2 tablespoons of the cooled spiced apple cider mixture into the bottom of each shot glass.
Step 5: Drizzle about 1 tablespoon of caramel sauce over the apple cider layer in each glass. For best results, chill briefly (10-15 minutes) if your caramel is very thin to help it set.
Step 6: Carefully spoon or pipe the cream cheese topping over the caramel layer. A piping bag with a star tip can create a beautiful presentation.
Step 7: Chill the assembled shots for at least 1-2 hours to allow all the layers to set and flavors to meld.
Step 8: Just before serving, thinly slice the Granny Smith apple and dip the slices in a little lemon juice to prevent browning. Garnish each shot with an apple slice and a light sprinkle of cinnamon.
