Ingredients You’ll Need
This recipe makes about 6–8 servings, depending on portion size.
- 1 package lime-flavored gelatin (3 oz box)
- 1 cup boiling water
- 1 cup cold water
- 1 can (20 oz) crushed pineapple, undrained
- 1 package (8 oz) cream cheese, softened
- 1 cup mini marshmallows
- 1 tub (8 oz) whipped topping, thawed (or 3 cups homemade whipped cream)
Optional garnishes: lime zest, fresh lime slices, or extra whipped cream.
Step-by-Step Instructions
Step 1: Dissolve the Gelatin
In a large bowl, pour boiling water over the lime gelatin mix. Stir until completely dissolved. Add the cold water and stir again. Place the bowl in the refrigerator for about 30–40 minutes, or until the mixture begins to thicken slightly but isn’t fully set.
Step 2: Prepare the Pineapple and Cream Cheese
In a separate bowl, combine the softened cream cheese with the crushed pineapple and its juice. Mix until smooth. A hand mixer makes this step easier, but you can also use a sturdy whisk.
Step 3: Combine Gelatin and Creamy Mixture
Fold the cream cheese-pineapple mixture into the partially set gelatin. Stir gently until everything is evenly blended.
Step 4: Add the Marshmallows
Stir in the mini marshmallows. These not only add sweetness and texture but also give the fluff its signature lightness.
Step 5: Fold in Whipped Topping
Gently fold in the whipped topping until no streaks remain. The mixture should be light, fluffy, and pale green.
Step 6: Chill and Serve
Pour the mixture into a serving bowl, trifle dish, or individual cups. Refrigerate for at least 4 hours, or overnight if possible, until fully set and chilled. Garnish with lime zest, whipped cream, or fresh lime slices before serving.
Tips for the Best Lime Fluff
- Soften the cream cheese – Let it sit at room temperature for about 30 minutes so it blends smoothly without lumps.
- Don’t skip the chill time – Lime fluff needs several hours in the fridge to firm up and develop its creamy texture.
- Use fresh lime zest – A sprinkle of zest on top before serving adds brightness and visual appeal.
- Make it in advance – This dessert tastes even better the next day, as the flavors meld together.
- Switch up the serving style – Use martini glasses for an elegant presentation or mason jars for a rustic look.
Flavor Variations
- Lemon Fluff – Swap lime gelatin for lemon gelatin for a tangy, sunshine-yellow dessert.
- Cherry Lime Fluff – Fold in drained maraschino cherries for color and extra sweetness.
- Tropical Fluff – Add shredded coconut and diced mango or papaya for a tropical twist.
- Pistachio Fluff – Use pistachio pudding mix instead of gelatin for a nutty variation.
- Holiday Fluff – Use red gelatin and top with green sprinkles for a festive holiday version.
Frequently Asked Questions
Can I use sugar-free gelatin?
Yes, sugar-free gelatin works perfectly if you want a lighter version with fewer calories.
Do I have to use canned pineapple?
Canned crushed pineapple is ideal because the juice helps balance the gelatin. Fresh pineapple contains enzymes that prevent gelatin from setting, so it’s best to stick with canned.
Can I use homemade whipped cream instead of whipped topping?
Absolutely. Whip 1 ½ cups of heavy cream with 2 tablespoons of sugar until soft peaks form, then fold it into the mixture.
How long does it need to chill?
At least 4 hours, but overnight is best for the fluffiest, creamiest result.
Can I turn this into a pie?
Yes! Simply pour the mixture into a graham cracker crust before chilling for a no-bake Lime Fluff Pie.
Nutrition Benefits
Lime Fluff is a light dessert compared to cakes and pies, with about 180–200 calories per serving. It contains vitamin C from the pineapple and a small amount of calcium from the cream cheese. While it’s not meant to be a health food, it’s a refreshing treat that satisfies a sweet tooth without being overly heavy.
Storage and Make-Ahead Tips
- Refrigerator – Store covered in the fridge for up to 3 days.
- Freezer – Not recommended, as freezing changes the texture of the gelatin and whipped topping.
