This easy-breezy lemon fluff dessert looks fancy, layering a crisp graham cracker crust with an airy, creamy citrusy topping. The truth? It’s made with evaporated milk, a boxed gelatin mix and crumbs.
Lighter than cheesecake but equally creamy, lemon fluff dessert relies on a brilliant blend of evaporated milk and lemon gelatin for its rich yet airy texture. By whipping the milk and then gently folding it into gelatin, you get all the fluffiness of whipped cream yet the dessert becomes a tad thicker, like a foamy, nontraditional cheesecake. Spoon the lemon-scented cream across a bed of crispy graham cracker crumbs, and you’ve got a delightful mix of soft and crunchy, citrus-y and sweet.
Lemon fluff bars may connote vintage baking—anything with Jell-O tends to feel a bit old-fashioned—but they’re far from fussy. Easy-going and deliciously cool, this is just the dessert for a balmy summer day.
Lemon Fluff Dessert Ingredients
Evaporated milk: Creamy evaporated milk whips into a dense yet fluffy dessert. Don’t confuse evaporated milk with condensed milk, which is way too sweet for this recipe.
Lemon gelatin: Using boxed gelatin makes the dessert stir together in a snap, and the packaged mix yields a consistently thick texture every time.
Sugar: Use plain white granulated sugar here, since it dissolves easily with the gelatin.
Lemon juice: Squeeze fresh lemon juice into the flavored Jell-O to really boost that citrus taste. Zest the lemon first and add it to the mixture for even more flavor.
Graham cracker crumbs: Blitz graham crackers into crumbs in a food processor, pop them into a freezer bag and crush them with a rolling pin, or buy pre-crushed cracker crumbs for an effortless crust.
Butter: Melted butter helps the graham cracker crumbs stick together to form a sturdy, crunchy base for the dessert bars.
Directions
Step 1: Chill the milk and beaters
Pour the evaporated milk into a metal bowl. Place it in the refrigerator along with your beaters or stand mixer whisk. Chill for two hours.
Editor’s Tip: Evaporated milk isn’t as thick as heavy cream but will hold sturdier peaks when whipped cold.
Step 2: Activate the gelatin
Meanwhile, in a large bowl, dissolve the gelatin and 1 cup sugar in 1-1/3 cup boiling water. Stir in the lemon juice. Cover the bowl and refrigerate until thick and syrupy, about 1 hour and 30 minutes.
Editor’s Tip: Don’t skimp on the water temperature. The gelatin needs boiling water to activate properly. It might sound strange to chill it immediately, but gelatin thickens as it cools. We’re not looking for solid Jell-O here but just a thick, syrupy liquid.
Step 3: Make the crumb crust
In a small bowl, combine the graham cracker crumbs, remaining sugar and melted butter. Stir until sandy and moist.
Scoop out 2 tablespoons and set aside to garnish the top of the lemon fluff bars.
Press the remaining crumbs onto the bottom of a 13×9-inch baking dish. Bake at 350°F for 10 minutes. Cool completely on a wire rack.
Editor’s Tip: The easiest way to press crumbs into a pan is to stamp them down with the bottom of a jar or drinking glass.
Step 4: Whip the milk
Remove the evaporated milk and beaters from the fridge. In the chilled metal bowl, beat the chilled milk until soft peaks form.
Editor’s Tip: As with egg whites, soft peaks should be loose and slightly drooping off the beaters. Whipping the milk too stiff may make the filling dry once you combine it with the gelatin.
Step 5: Beat the gelatin
Beat the thickened gelatin mixture until lots of tiny bubbles form and it looks foamy.
Step 6: Combine the milk and gelatin
Gently fold the whipped milk into the gelatin.
