Creamy & Dreamy Key Lime Icebox Cake 🍋❄️
There’s nothing like a cool, citrusy dessert on a warm day, and this Key Lime Icebox Cake is the perfect sweet and tangy treat! 🍈✨ It’s no-bake, super simple, and so refreshing. Layers of graham crackers, a creamy key lime filling, and a hint of zest make this dessert a must-try!

This cake is the ultimate lazy baker’s dream! No oven, no fussy techniques, just simple ingredients that turn into something magical with time. The balance of tangy key lime and sweet, creamy filling is absolute perfection. If you love key lime pie but want something even easier, this is it! Plus, it’s a great make-ahead dessert—just let it chill in the fridge, and it’s ready whenever you are.

I also love how customizable this recipe is. You can swap out the graham crackers for vanilla wafers or shortbread cookies for a fun twist. Want an extra burst of lime flavor? Stir in more zest or add a drizzle of lime syrup on top. You could even layer in some crushed pineapple or coconut for a tropical vibe! 🌴🥥

This Key Lime Icebox Cake is a go-to for potlucks, BBQs, and anytime I need a quick and refreshing treat. It disappears fast, so you might want to make a double batch!

Key Lime Icebox Cake

Ingredients

For the filling:
1 (8 oz) block cream cheese, softened
1 (14 oz) can sweetened condensed milk
1 cup heavy whipping cream
½ cup key lime juice (fresh is best!)
1 tsp vanilla extract
Zest of 2 key limes

For layering:
1 ½ sleeves graham crackers
Whipped cream
Lime zest & thin lime slices

Instructions

Make the filling – In a large bowl, beat the cream cheese until smooth. Mix in the sweetened condensed milk, key lime juice, vanilla, and lime zest. In a separate bowl, whip the heavy cream to stiff peaks, then gently fold it into the lime mixture.

Layer it up – In an 8×8-inch dish, spread a thin layer of the filling on the bottom. Add a single layer of graham crackers and then a layer of whipped cream. Repeat the layers until you run out of filling, ending with a creamy layer on top.

Chill – Cover and refrigerate for at least 4 hours (overnight is even better!) to let the flavors meld and the crackers soften into a cake-like texture.

Garnish & serve – Spread extra whipped cream on top, sprinkle with lime zest, and decorate with lime slices. Slice, serve, and enjoy the creamy citrusy goodness!
