1. Start by preparing the pudding mixture. In a medium bowl, combine the instant vanilla pudding mix with the milk. Whisk vigorously until the mixture begins to thicken, ensuring a smooth consistency.
2. Gently fold in the whipped topping into the pudding until fully combined. This addition will lend an airy texture to the mixture.
3. Core and chop the apples into bite-sized pieces, leaving the skin on for texture. For a varied taste, use a mix of Granny Smith, Fuji, and Red Delicious apples.
4. Chop the Snickers candy bars into small chunks. If desired, also prepare mini marshmallows. Add these to the pudding mix along with the chopped apples.
5. Stir all the ingredients together until they are well-coated with the creamy pudding mixture. Optionally, add in grapes, strawberries, or any additional toppings like nuts, pretzels, or chocolate chips.
6. Transfer the mixture to a serving bowl. For an extra decorative touch, drizzle caramel sauce on top and sprinkle lightly with cinnamon.
7. Chill the Snickers Salad in the refrigerator for at least an hour to allow the flavors to meld together. Serve chilled and enjoy this sweet and tart dessert.
