Making Cranberry Fluff is a simple and straightforward process if you follow these easy steps:

1. Prep the Cranberries: If using fresh cranberries, rinse them under cold water. If using frozen cranberries, let them thaw first.

2. Sweeten the Berries: In a medium bowl, combine cranberries and granulated sugar. Mix well and let them sit for about 10-15 minutes to allow the sugar to draw out the juices from the cranberries.

3. Whip the Cream: In a separate bowl, whip the heavy cream with the vanilla extract until stiff peaks form. This will create a light and airy texture for your fluff.

4. Mix Ingredients: In a large mixing bowl, combine the sweetened cranberries, miniature marshmallows, drained crushed pineapple, and chopped nuts (if using).

5. Fold in the Cream: Carefully fold the whipped cream into the cranberry mixture. Make sure everything is well combined but avoid overmixing to maintain the fluffiness.

6. Chill the Dish: Transfer the mixture to a serving bowl or dish, cover it with plastic wrap, and refrigerate for at least 2 hours. This chilling allows the flavors to meld beautifully.

7. Serve: Once chilled, give the Cranberry Fluff a gentle stir before serving. You can garnish it with extra nuts or additional cranberries if desired.
