Ingredients You’ll Need
The beauty of this dessert is how simple yet essential each component is, working in harmony to create a showstopping treat. Every ingredient here brings something delightful to the table—whether it’s color, flavor, or a creamy texture that melts in your mouth!
- Mint chocolate sandwich cookies: These add a bold, minty crunch and form the sturdy base for the St. Patrick’s Day shamrock lasagna dessert.
- Unsalted butter: Melted and mixed with crushed cookies, it helps bind the crust and enhances that rich flavor.
- Cream cheese: Softened cream cheese creates a tangy, creamy middle layer that always surprises with each bite.
- Granulated sugar: Just enough sweetness to balance the tang of the cream cheese without overpowering the dessert.
- Milk: Used in several layers for luscious, smooth consistency—don’t skip it!
- Whipped topping: Fluffy and light, this makes the whole dessert feel airy and dreamy—perfect for St celebrations!
- Instant pistachio pudding mix: The star of the show, bringing a light nutty flavor and festive green color.
- Instant vanilla pudding mix: Balances the flavors and adds vanilla sweetness to the creamy layers.
- Cold milk (for pudding): Essential for activating the puddings and making that thick, custardy layer.
- Green food coloring (optional): For that extra pop of St green—use it if you’re feeling festive!
- Green or shamrock-shaped sprinkles: The final touch for a truly magical and cheerful St presentation.
How to Make St
Step 1: Create the Cookie Crust
In a medium bowl, combine your crushed mint chocolate sandwich cookies with melted butter and mix until every crumb is beautifully coated. Then press this delicious mixture firmly into the bottom of a 9×13-inch dish. This will be the sturdy, chocolatey foundation for your St. Patrick’s Day shamrock lasagna dessert.
Step 2: Whip Up the Cream Cheese Layer
In a separate bowl, beat together the softened cream cheese, granulated sugar, and two tablespoons of milk until everything is silky-smooth. Gently fold in one cup of whipped topping to make this mixture light and fluffy, then carefully spread it over your cookie crust for a dreamy, creamy foundation.
Step 3: Prepare the Pudding Layer
Using another large bowl, whisk together the pistachio pudding mix and vanilla pudding mix with three cups of cold milk. Keep whisking until the mixture thickens up, which should take about two minutes. If you want your dessert extra festive, add a few drops of green food coloring until you reach Shamrock perfection. Smooth this thick, velvety layer over the cream cheese mixture.
Step 4: Top with Whipped Topping and Decorate
Dollop the rest of your whipped topping over the pudding layer and gently spread it out to create a cloud-like finishing touch. For that fabulous St party flair, scatter plenty of green or shamrock-shaped sprinkles on top. Pop your baking dish in the fridge for at least 4 hours—overnight is perfect for optimal slicing and flavor!
How to Serve St

Garnishes
A gently smooth top with a snowfall of green or shamrock sprinkles instantly says “Celebrate St Patrick’s Day!” If you want to go all out, a few fresh mint leaves or a sprinkle of crushed pistachios can add extra charm and color.
Side Dishes
This dessert pairs beautifully with hot coffee or a tall glass of cold milk. For a dessert buffet at your St gathering, serve alongside fresh berries or a tray of buttery shortbread cookies for an irresistible Irish-inspired treat spread.
Creative Ways to Present
Cut the lasagna into shamrock shapes with a large cookie cutter for a totally St-worthy look, or layer individual servings in mason jars or clear cups to show off those gorgeous green-and-white strata. Tiny party parfaits are always a crowd-pleaser!
Make Ahead and Storage
Storing Leftovers
If you’re lucky enough to have any St. Patrick’s Day shamrock lasagna dessert left after your celebration, simply cover the dish tightly with plastic wrap or a lid and keep in the refrigerator for up to four days. The flavors just deepen overnight!
Freezing
This is a handy St treat to prepare ahead. Freeze the whole assembled dessert (skip the sprinkles until ready to serve) tightly wrapped for up to a month. Thaw overnight in the fridge before finishing with sprinkles and serving.
Reheating
Since this dessert is meant to be enjoyed chilled, there’s thankfully no need to reheat. Just slice, plate, and let the cloud-like layers delight your guests straight from the fridge!
FAQs
Can I use a different flavor of pudding if I don’t like pistachio?
Absolutely! If pistachio isn’t your favorite, try using only vanilla pudding, or swap in white chocolate or cheesecake flavor for a unique twist while still keeping the lush green theme for St parties by using green food coloring.
What are some nut-free alternatives for those with allergies?
You can substitute the pistachio pudding with an extra vanilla or instant white chocolate pudding mix and still achieve that festive green color with a little food coloring—everyone can join the St. Patrick’s Day fun!
Is there a way to make this dessert gluten-free?
There are several gluten-free chocolate sandwich cookies available at most grocery stores; just use your favorite brand and be sure the pudding mixes are also gluten-free for a safe and equally delicious St. Patrick’s Day treat.
How can I make the dessert more minty or less minty?
If you love a stronger mint flavor for your St celebration, add half a teaspoon of peppermint or mint extract to the cream cheese layer. For a milder taste, stick to regular chocolate sandwich cookies and skip the extract altogether.
How far in advance can I make this St. Patrick’s Day shamrock lasagna dessert?
You can assemble the entire dessert, cover it tightly, and keep it in the fridge up to 2 days ahead—just wait to add the sprinkles until a few hours before serving so they stay crisp and colorful!
