Today we’re sharing with you a fun twist on a traditional key lime pie: a No Bake Key Lime Dessert Lasagna, or Key Lime Lush as we like to call it! It’s a layered dessert with all of your favorite flavors and textures of a key lime pie, taken to another level of indulgence.

Key Lime Pie Dessert Lasagna Recipe

When I first heard the term “dessert lasagna,” I was baffled. If I hear the word lasagna I immediately think of tomatoes, pasta, cheese… but when you think of a lasagna as a layered pasta dish, it makes sense to refer to these fun layered desserts as dessert lasagnas. (Although it has taken me at least 5 years to stop thinking tomato when I hear the term.)

This key lime pie dessert lasagna is our latest in our collection of layered desserts, which includes our Cherry Chocolate Dessert Lasagna, our Lemon Lush and Pistachio Dessert Lasagna, along with a few others!

Instead of a traditional graham cracker crust like you see with most key lime pie-inspired recipes, we went with a Golden OREO crust for a slightly different flavour profile. You can use graham crackers instead, if desired.

Layered over the Golden OREO base is a key-lime infused cheesecake layer that is rich, tart and sweet, followed by a whipped topping that is essentially equal parts cheesecake and Cool Whip.

This is an indulgent, rich dessert with plenty of key lime flavor – and my favorite part is that it’s a completely no-bake recipe, because the last thing I need on a hot summer day is to heat up the house with the oven.

Recipe Questions:

How to Store: This No Bake Key Lime Lush can be stored in an airtight container in the fridge for up to 5 days. After that, it’s still edible but the consistency of the cookie crust and whipped topping change.

Can this Key Lime Pie Dessert Lasagna be frozen? I personally do not recommend freezing no bake cheesecake-type desserts, but it can be frozen in an airtight freezer container for up to 2 months. (This set of freezer containers is a crazy bargain.)

Can I substitute key lime juice and zest with regular limes? Yes, if you’re making this recipe out of season or just cannot source key limes, you can use regular limes, just note that you may want to increase the sugar slightly to make up for the tarter flavour of regular limes.

You can also use bottled key lime juice (I always have a bottle in the fridge during the summer – that way I can make a key lime dessert whenever the craving hits).

How to Make Key Lime Lush

For the Oreo Crust:

Place the oreos in a food processor and pulse to break down into crumbs. Reserve 1 1⁄2 cups of the cookie crumbs and place to the side.

Mix the remaining crumbs with the melted butter. Press this mixture into the bottom of a 9×13 baking dish. Set aside.

For the Key Lime Cheesecake Filling:

In a large bowl, beat the cream cheese with an electric mixer until smooth and no lumps remain.

Add in the pudding mixture and beat until combined.

Reduce speed of the electric mixer to slow, and add 2 cups of the Cool Whip (I like to add 1 cup at a time) along with the key lime juice.

Reserve 2/3 cup of this mixture to the side.

Take the remaining cream cheese mixture that is in the bowl and pour onto the cookie crust. Smooth down into an even layer with an offset spatula or the back of a spoon.

Evenly spread the reserved cookie crumbs on top of the cream cheese mixture.

For the Whipped Topping:

Take the reserved 2/3 cup of the cream cheese mixture and fold with 1 cup of Cool Whip, along with the key lime zest.

Pour this mixture over the cookie crumb layer in the casserole dish and use an offset spatula to smooth into an even layer.

To Decorate:

If desired, zest an additional lime over the top of the key lime lush .

Then scoop the remaining 1/2 cup of Cool Whip into a piping bag fitted with a large star tip and make small dollops onto each portion of the dessert.

Refrigerate to set for 6 hours or overnight before serving.

Just before serving, place a small lime wedge into the middle of the dollops. (If placed before storing in the fridge, the lime slices can become bitter and impart that bitter flavor to the Cool Whip.)
