Christmas Cookie Lasagna

WANT TO SAVE THIS RECIPE?

There’s something about a layered holiday dessert that makes a table feel instantly more festive. This Christmas Cookie Lasagna is what I bring when I want gasps, second helpings, and recipe requests. It’s cold, creamy, crunchy, and unmistakably merry — thanks to festive layers of chocolate cookie crust, velvety cream cheese mousse, crushed holiday cookies, and whipped topping showered in red and green M&Ms.

I first brought this to a neighborhood cookie swap and left with none. People who normally “just want a bite” went back for thirds. It’s a dessert that eats like a cake, chills like a cheesecake, and builds like a lasagna — and that combo just works.

You get layers of intense texture here. A fudgy chocolate base (I use brownie mix for structure), followed by a no-bake vanilla cream cheese layer, a crunchy cookie crumble that mimics the top of a crisp, and the holiday flair of whipped cream peaks dotted with M&Ms and red sugar.

What Makes This Christmas Cookie Lasagna Stand Out

This isn’t just a fridge dessert with crushed cookies and whipped topping. The structure matters here. I use a brownie base instead of crushed Oreos, which adds depth and chew. The middle layer is a stabilized cream cheese mousse that slices clean but melts in your mouth. I fold in Cool Whip with softened Philadelphia cream cheese and a dash of almond extract — it’s subtle, but trust me, it adds holiday warmth.

I layer that over the baked brownie base, then cover it with crushed golden sandwich cookies mixed with brown sugar and melted butter. It toasts just slightly in the fridge, enough to mimic a crumble topping. Finally, a generous layer of whipped topping gets piped over the top and dotted with red and green M&Ms.

It looks fancy but comes together with no more than moderate effort and a 9×13 pan. No baking skills required beyond the brownie base. I recommend a stand mixer or a hand mixer for the mousse layer, but a good spatula and chilled bowl will do in a pinch.

Brownie Base vs. Cookie Crust – Which Is Better?

Let’s talk about one of the first decisions you’ll make: base layer. I’ve tested this both ways.

In my notes: Brownie base gives a chewy, rich foundation that supports the cream and crumble layers beautifully. It also holds up over time in the fridge. Crushed cookie crusts (like Oreos or chocolate grahams) make it too crumbly and don’t contrast as well with the cream layer. If you want a lasagna that slices clean and holds its shape on a dessert tray, brownie wins.

I use a basic box mix like Ghirardelli Triple Chocolate, baked just until set. Let it cool fully before layering anything on top. It’s the anchor.

Why I Recommend 8 oz Cream Cheese + 1/2 tsp Almond Extract

This layer is what keeps the lasagna from being just sweet-on-sweet. I use 8 oz of full-fat Philadelphia cream cheese, softened, and whip it with powdered sugar and Cool Whip. The almond extract — just half a teaspoon — brings a subtle nutty note that makes the whole thing taste like Christmas cookies.

I’ve tried it with vanilla extract only, and it was fine. But the almond edge made people stop and say, “what is that?” in the best way. It’s not overpowering, just elevating.

Use the Right Pan for Best Results

I tested this in glass, metal, and ceramic pans. Here’s the deal: use a ceramic or glass 9×13. Metal pans can overbake the brownie base, especially on the edges. Glass gives even cooling, and ceramic holds the chill longer when you serve.

Make sure to line with parchment if you want to lift the whole thing out for clean slicing. But for casual parties, serving directly from the pan works perfectly.

The Crumble Layer: Buttery Texture and Never Skipped

The golden cookie crumble layer is where the texture magic happens. I crush 12 golden Oreos (or vanilla sandwich cookies) and mix with 2 tablespoons melted butter and 2 tablespoons brown sugar. It firms up just enough to give crunch against the soft mousse.

I’ve tried the recipe without it once. Never again. It was fine, but too one-note. The crumble adds contrast, and it balances the richness of the cream and brownie. I press it gently onto the mousse layer with a spoon before chilling.

How to Chill for a Clean Slice and Stable Texture

After layering everything, you need to chill this dessert for at least 4 hours. Overnight is better. The cream cheese layer sets fully, and the crumble fuses slightly with the top.

Use an offset spatula to spread layers evenly. I pipe the final whipped topping with a star tip for drama, but a spoon swirl works too. Top with red and green M&Ms (I prefer peanut for crunch) and red nonpareils. The visual is instant holiday joy.

Slice with a sharp, hot knife. Clean between cuts. The layers should stay intact and gorgeous.

How Long It Lasts and How to Store This Christmas Cookie Lasagna

Serve chilled straight from the fridge. It’s best cold, not room temp. The mousse stays set and the M&Ms don’t bleed.

Store tightly covered in the fridge up to 5 days. It holds up shockingly well. The brownie stays moist, the mousse firm, and the crumble layered. If you’re freezing, wrap tightly and freeze up to one month — thaw overnight in the fridge.

Other Holiday Desserts I Bake Just As Often

This is part of my go-to Christmas rotation. When I want to balance it with something warm or citrusy, I reach for my gingerbread bundt with lemon glaze, soft frosted eggnog sugar cookies, peppermint Oreo fudge, and cranberry orange loaf with glaze. Each one brings a different kind of holiday magic to the table.

Pin This Recipe and Come Back to It Anytime

This one’s on my Pinterest board called “Cold Christmas Desserts” — it always gets repinned. If you try it, let me know: Did you use the brownie base or cookies? Did the almond extract win you over?

Tag me with your lasagna pics, especially if you get wild with the toppings. I’ve seen crushed candy canes, mini chocolate chips, and even white chocolate drizzle. Share the joy and spread the layers.

Equipment Notes That Make a Difference

Stand mixer: Ideal for whipping the mousse until fluffy. Hand mixer works too.

9×13 glass or ceramic pan: For even cooling and best presentation.

Offset spatula: Helps smooth each layer cleanly.

Piping bag with star tip: Optional, but gives the top that extra holiday pop.
