Lemon Fluff Dessert Recipe
Introduction
Lemon Fluff Dessert is a light, airy treat with a bright lemon flavor wrapped in a buttery graham cracker crust. This no-bake dessert is perfect for warm days and simple enough for any home cook to make with pantry staples.

Ingredients
- 1 can (12 ounces) evaporated milk
- 1 package (3 ounces) lemon gelatin
- 1-1/4 cups sugar, divided
- 1-1/3 cups boiling water
- 1/4 cup lemon juice
- 2 cups graham cracker crumbs
- 1/2 cup butter, melted
Instructions
- Step 1: Chill the evaporated milk and beaters by placing them in the refrigerator for two hours. This helps the milk whip better and form sturdier peaks.
- Step 2: In a large bowl, dissolve the lemon gelatin and 1 cup of sugar in 1-1/3 cups boiling water. Stir in the lemon juice, cover, and refrigerate until thick and syrupy, about 1 hour and 30 minutes.
- Step 3: Prepare the crumb crust by combining graham cracker crumbs, remaining sugar, and melted butter in a small bowl. Stir until the mixture is sandy and moist.
- Step 4: Reserve 2 tablespoons of the crumb mixture for garnish. Press the remainder firmly on the bottom of a 13×9-inch baking dish. Bake at 350°F for 10 minutes, then cool completely on a wire rack.
- Step 5: Remove chilled milk and beaters from the fridge. Beat the milk in a chilled metal bowl until soft peaks form, being careful not to overbeat.
- Step 6: Beat the thickened gelatin mixture until foamy with lots of tiny bubbles.
- Step 7: Gently fold the whipped milk into the foamy gelatin using a spatula, preserving the airiness by folding rather than stirring.
- Step 8: Pour the combined mixture over the cooled crumb crust. Sprinkle the reserved crumbs on top.
- Step 9: Cover and refrigerate until the dessert is set, then cut into squares and serve.
Tips & Variations
- Use the bottom of a jar or drinking glass to press the crumb crust evenly into the pan for a compact base.
- For extra tang, add a teaspoon of lemon zest to the gelatin mixture before chilling.
- Try substituting lime gelatin and juice for a refreshing twist on the flavors.
Storage
Store leftover Lemon Fluff Dessert covered in the refrigerator for up to 3 days. To serve, let it sit at room temperature for 10 minutes for softer texture, though it’s best enjoyed chilled.

FAQs
Can I use regular gelatin instead of lemon gelatin?
Yes, but you will need to add lemon juice or lemon zest separately to achieve the same tangy flavor. Adjust sweetness to taste.
Is evaporated milk necessary, or can I use heavy cream?
Evaporated milk is preferred because it whips well when chilled and creates a lighter texture. Heavy cream can be substituted but will make the dessert richer and denser.

Ingredients
Filling:
- 1 can (12 ounces) evaporated milk
- 1 package (3 ounces) lemon gelatin
- 1–1/4 cups sugar, divided
- 1–1/3 cups boiling water
- 1/4 cup lemon juice
Crust:
- 2 cups graham cracker crumbs
- 1/4 cup sugar (from the 1–1/4 cups divided sugar; 1 cup used in gelatin, 1/4 cup here, and 1/4 reserved on top)
- 1/2 cup butter, melted
Instructions
- Chill the milk and beaters: Pour the evaporated milk into a metal bowl and place it along with your beaters or stand mixer whisk into the refrigerator for two hours to chill. This ensures the milk whips to soft peaks effectively.
- Activate the gelatin: In a large bowl, dissolve the lemon gelatin and 1 cup sugar in 1-1/3 cups boiling water. Stir in the lemon juice, cover, and refrigerate until the mixture thickens and becomes syrupy, about 1 hour and 30 minutes.
- Make the crumb crust: In a small bowl, mix graham cracker crumbs, 1/4 cup sugar, and melted butter until the mixture is sandy and moist. Reserve 2 tablespoons of this crumb mixture for topping. Press the remaining crumbs firmly onto the bottom of a 13×9-inch baking dish. Bake at 350°F (177°C) for 10 minutes and cool completely on a wire rack.
- Whip the milk: Remove the chilled evaporated milk and beaters from the fridge. Beat the milk in the chilled metal bowl until soft peaks form, being careful not to overwhip to retain moisture in the filling.
- Beat the gelatin: Beat the thickened gelatin mixture until it is foamy and full of tiny bubbles.
- Combine the milk and gelatin: Gently fold the whipped milk into the beaten gelatin using a spatula with gentle folding motions to preserve the airiness of the mixture.
- Layer and chill: Pour the combined milk and gelatin mixture over the cooled graham cracker crust. Sprinkle the reserved crumb mixture on top to garnish. Cover and refrigerate until firmly set. Once set, cut into squares and serve chilled.
Notes
- Chilling the evaporated milk and beaters is essential to achieve good whipping volume.
- Use boiling water to dissolve the gelatin properly; cold water will not activate it.
- Do not overwhip the evaporated milk to avoid a dry filling texture.
- Folding the whipped milk into gelatin gently preserves the fluffy texture.
- Press the graham cracker crumbs firmly into the pan to create a solid crust base.
- Allow the crust to cool completely before adding the filling to prevent sogginess.
