Ingredients in Key Lime Crack
Here’s what goes into this sweet and tangy masterpiece:
Graham Cracker Crumbs
The buttery, slightly salty base that provides the perfect crunch.
Butter
Melted and mixed with crumbs to form the irresistible crust.
Sweetened Condensed Milk
Thick, rich, and perfectly sweet—it’s the creamy backbone of the filling.
Cream Cheese
Adds tang and structure for a thick, luscious filling.
Key Lime Juice
Tart and citrusy—this is what gives the dessert its signature zing. Bottled works, but fresh is even better.
Lime Zest

Gives the filling that light, airy texture.

Instructions
Here’s how to whip up this cool, creamy treat:
Make the Crust
In a bowl, mix graham cracker crumbs with melted butter until fully coated. Press into a parchment-lined baking dish to form an even crust. Chill in the fridge to firm up.
Mix the Filling
In a large bowl, beat cream cheese until smooth. Add sweetened condensed milk, lime juice, and zest. Beat until creamy and fully combined.
Fold in Whipped Topping
Gently fold in whipped topping or fresh whipped cream until the mixture is light and fluffy.
Assemble
Spread the filling evenly over the chilled crust. Smooth the top with a spatula.
Chill Until Set
Refrigerate for at least 4 hours, or overnight if you can wait. The longer it chills, the easier it is to slice.
Slice and Serve
Cut into squares or bars, sprinkle with sea salt flakes if desired, and get ready to fall in love.
