Ingredients Method Notes

Ingredients
  

  • Ingredients You’ll Need
  • 8 oz cream cheese softened
  • ½ cup powdered sugar
  • 8 oz whipped topping thawed
  • Juice of 1 fresh lemon
  • ¼ teaspoon lemon extract optional, for a stronger citrus kick
  • 3 cups mini marshmallows
  • 18 oz fresh blueberries
  • Lemon zest optional, for garnish
  • Sliced almonds optional, for topping

Method
 

1. Create the Creamy Base

In a large mixing bowl, beat the softened cream cheese and powdered sugar using a hand mixer until silky smooth and lump-free.

    Tip: make sure the cream cheese is fully softened to avoid a grainy texture.

2. Add the Light & Fluffy Elements

Switch to a spatula and gently fold in the whipped topping. Pour in the fresh lemon juice and add lemon extract if using. Mix carefully until everything looks smooth, airy, and evenly combined.

    3. Fold in the Good Stuff

    Add the blueberries and mini marshmallows to the bowl. Fold everything together slowly so the fruit stays intact and gets evenly coated in that creamy mixture. Don’t rush this step—gentle folding keeps the fluff texture perfect.

      4. Chill to Perfection

      Cover the bowl with plastic wrap and refrigerate for at least 30 minutes, or up to 1 hour. This helps the flavors blend and the texture firm up slightly.

        5. Finish & Serve

        Right before serving, sprinkle lemon zest and sliced almonds on top if you like a little extra flavor and crunch. Serve chilled and enjoy!

          Serving Suggestions

          Expert Tips for the Best Fluff

          • Use full-fat cream cheese for the creamiest result (IMO, it’s worth it).
          • Chill before serving—this step makes a big difference in texture.
          • Pat blueberries dry to prevent excess moisture from thinning the mixture.
          • Fold, don’t stir aggressively to keep everything light and fluffy.

          Frequently Asked Questions

          Can I use frozen blueberries?
           Yes, but thaw and drain them first. Fresh berries give the best texture.
          How long does it last in the fridge?
           Store covered for up to 2–3 days. Give it a gentle stir before serving again.
          Can I make it ahead of time?
           Absolutely! It’s actually better after a few hours of chilling.
          Is lemon extract necessary?
           Not at all—it just enhances the lemon flavor if you want it extra zesty.
