Prepare the Lemon Jello: In a small saucepan, heat the ¼ cup of water until it reaches boiling. Stir in the sugar-free lemon Jello mix until completely dissolved. Set aside to cool slightly.
Whip the Cream Cheese: In a large mixing bowl, beat the softened cream cheese with a hand mixer on medium speed until smooth and creamy. This step ensures the cream cheese integrates perfectly into the fluff.
Incorporate the Lemon Jello: Gradually add the warm, dissolved Jello mixture to the cream cheese and blend until smooth and well combined.
Whip the Heavy Cream: In a separate bowl, whip the heavy cream on high speed until stiff peaks form, about 3–4 minutes. Be sure not to overwhip, or the cream may separate.
Combine the Mixtures: Gently fold the whipped cream into the cream cheese and lemon mixture using a spatula. Take care to fold it slowly to maintain the fluffy texture.
Chill and Set: Transfer the mixture to a serving dish or individual cups. Refrigerate for at least 2 hours to allow the fluff to firm up and set.
Serve: Before serving, garnish with a squeeze of fresh lemon juice, lemon zest, or a few berries for added color and flavor. Enjoy the light, refreshing taste!
