A festive, no-bake layered treat, this Shamrock Shake Dessert Lasagna takes inspiration from the iconic minty green shake served each March. I layer a rich Oreo cookie crust, a sweet and fluffy cream cheese blend, a refreshing mint pudding layer, and top it all with whipped topping, chocolate chips, and green sprinkles. It’s cool, creamy, and perfect for celebrating St. Patrick’s Day—or for any moment I’m craving a fun, minty dessert.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the Oreo Crust:

36 Oreo cookies, crushed

6 tablespoons melted butter

For the Cream Cheese Layer:

8 ounces cream cheese, softened

1/2 cup powdered sugar

2 cups whipped topping (e.g., Cool Whip)

For the Mint Pudding Layer:

1 (3.4‑ounce) package instant vanilla pudding mix

1 1/2 cups milk

1/2 teaspoon mint extract

Green food coloring, a few drops as needed

For Topping:

1 cup whipped topping

Chocolate chips, for garnish

Green sprinkles, for garnish

Directions

I start by crushing the Oreo cookies into fine crumbs using a food processor or by sealing them in a zip-top bag and rolling over them with a rolling pin.

Then I mix the crushed Oreos with melted butter until the texture feels like wet sand, then firmly press it into the bottom of a 9×13-inch dish to form the crust.

I pop the dish in the fridge to chill while I prepare the next layer.

In a medium bowl, I beat the softened cream cheese and powdered sugar until smooth. Then I gently fold in the whipped topping and spread this creamy layer over the chilled crust.

For the pudding layer, I whisk together the pudding mix, milk, mint extract, and a few drops of green food coloring until smooth and thickened. I spread this evenly over the cream cheese layer.

I finish it off with a layer of whipped topping, smoothing it out with a spatula.

Next I sprinkle chocolate chips and green sprinkles on top for that festive finish.

I cover the dish and refrigerate it for at least 4 hours—or overnight—until it sets completely.

Once chilled, I slice it into squares and serve it cold.

Variations

I like swapping the Oreo crust for mint Oreos for an extra minty punch.

Instead of instant vanilla pudding, I’ve also used white chocolate or pistachio pudding for a twist.

For a lighter option, I sometimes use low-fat cream cheese and reduced-fat whipped topping.

I’ve added a layer of chocolate ganache between the pudding and whipped topping for a richer version.

Crushed Andes mints or chopped Thin Mints make great toppings in place of chocolate chips.

Storage/Reheating

I store leftovers in the fridge, covered, for up to 4 days. Since this is a chilled dessert, there’s no reheating needed. I avoid freezing it, as the creamy layers tend to lose their smooth texture when thawed.

FAQs

What kind of mint extract should I use?

I use peppermint extract for this recipe—it gives the clean, cool mint flavor similar to a Shamrock Shake. I avoid spearmint, which has a different taste profile.

Can I make this dessert ahead of time?

Absolutely. I like making it the night before and letting it chill overnight. The flavors meld, and the layers hold together better when fully set.

Can I use homemade whipped cream instead of Cool Whip?

Yes, I’ve used homemade whipped cream (whipped heavy cream with a bit of sugar and vanilla), and it works beautifully. Just make sure it’s whipped to stiff peaks so it holds up in the layers.

How do I keep the layers from mixing together?

I make sure each layer is chilled or thickened before adding the next one. I also gently spread each layer with a spatula to avoid disrupting the one beneath it.

What dish size works best for this recipe?

I always use a 9×13-inch dish for even layering and easy slicing. A glass dish makes it easy to show off the layers if I’m serving guests.

Conclusion

This Shamrock Shake Dessert Lasagna is a minty, creamy, no-bake dream. It’s festive enough for St. Patrick’s Day, but so good that I find myself making it year-round. Whether I’m hosting a party or just want to treat myself, this layered dessert always delivers on flavor and fun—no oven, no stress, just sweet satisfaction in every bite.
