Description

This Lemon Fluff Dessert is a delightfully light and airy no-bake treat packed with zesty lemon flavor and the sweet tang of crushed pineapple. With a creamy whipped topping and optional mini marshmallows, it’s a cool, refreshing dessert that’s perfect for warm days, family gatherings, or potlucks. All it takes is a handful of ingredients—and a little patience while it chills—for a citrusy, nostalgic dessert everyone will love.


Ingredients

Scale

Lemon Mixture

  • 1 (3 oz) box lemon Jello
  • 1 cup boiling water
  • 1/2 cup cold water

Fruity Add-Ins

  • 1 (8 oz) can crushed pineapple, undrained

Fluffy Layer

  • 1 (8 oz) tub whipped topping, thawed
  • 1/2 cup mini marshmallows (optional)
  • 1 teaspoon lemon zest (optional, for extra citrus flavor)


Instructions

  1. Dissolve the Jello: In a large bowl, pour the boiling water over the lemon Jello powder. Stir thoroughly until the Jello is completely dissolved and the mixture is clear, ensuring no granules remain.
  2. Add Pineapple and Cold Water: Stir in the cold water and undrained crushed pineapple. Mix well to combine, ensuring the pineapple is evenly distributed throughout the Jello base.
  3. Chill Until Thickened: Place the bowl in the refrigerator and let the mixture chill for about 30–45 minutes, or until it is slightly thickened but not fully set. It should have a syrupy, pudding-like consistency to hold the fluffy additions.
  4. Fold in Whipped Topping: Gently fold in the thawed whipped topping, mini marshmallows if using, and lemon zest for extra zing. Mix until everything is well incorporated and the mixture becomes light and fluffy.
  5. Transfer and Chill: Spoon the mixture into a serving bowl or divide among individual cups. Chill for at least 2 hours or until fully set. Serve cold, garnished with extra lemon zest if desired.

Notes

  • Pineapple must be undrained—its juice adds sweetness and moisture.
  • Marshmallows add a fun texture but are entirely optional.
  • For a tarter flavor, increase the lemon zest or add a tablespoon of fresh lemon juice.
  • This dessert can be made a day ahead; cover well and refrigerate until ready to serve.
  • Try serving in individual cups for easy, portable potluck treats.
