1package (14.4 oz)graham crackersor lemon shortbread cookies
Instructions
In a large, chilled mixing bowl, whip the cold heavy cream with an electric mixer on high speed until stiff peaks form, about 3-5 minutes. Be careful not to overmix.
In a separate medium mixing bowl, combine the cold sweetened condensed milk, fresh lemon juice, and lemon zest. Whisk until thoroughly combined and the mixture has slightly thickened.
Gently fold the whipped cream into the lemon-condensed milk mixture using a rubber spatula until no streaks of white remain. Be gentle to maintain the airiness of the whipped cream.
Arrange a single layer of graham crackers at the bottom of a 9x13 inch baking dish, breaking them as needed to fit snugly.
Spread about one-third of the lemon cream mixture evenly over the graham crackers. Repeat with another layer of graham crackers, followed by another third of the lemon cream mixture. Finish with a final layer of graham crackers and the remaining lemon cream.
Cover the baking dish tightly with plastic wrap and refrigerate for at least 4 hours, or preferably overnight, to allow the crackers to soften and the cake to set.
Before serving, you may garnish with extra lemon zest, fresh berries, or a light dusting of powdered sugar. Slice and enjoy your refreshing No Bake Lemon Ice Box Cake!
Notes
For best results, ensure all dairy ingredients are well-chilled before mixing. This helps the cream whip better and the mixture to set properly. You can experiment with different types of cookies for the base, such as vanilla wafers or lemon shortbread cookies, for a different flavor profile. The cake will keep in the refrigerator for up to 3-4 days.
