St. Patrick’s Day Shamrock Lasagna Dessert is a fun and festive treat that’s perfect for celebrating with a little green flair. Layers of creamy whipped topping, green-tinted pudding, crushed cookies, and chunks of minty candy come together to create a sweet, no-bake dessert that looks as playful as it tastes. The shamrock shape on top adds that perfect holiday touch everyone loves to see.
I enjoy making this dessert because it’s super easy to put together, so you don’t have to spend all day in the kitchen. I like to crush my cookies just the right amount, leaving some bigger bits for texture. It’s also a great way to sneak in some mint flavor without it being too strong, which my family really appreciates. The green color always makes everyone smile, even before they take their first bite!
My favorite way to serve this is chilled with a little extra whipped topping sprinkled with green sugar or chocolate chips on top. It’s a great ending to any St. Patrick’s Day meal or a sweet snack to share with friends. Every year, I look forward to making this shamrock lasagna because of all the happy faces gathered around the table and the fun memories we create while enjoying it together.
Key Ingredients & Simple Swaps
Cream Cheese: This gives the dessert its creamy base and rich flavor. If you want a lighter option, try using light cream cheese or even mascarpone for a smoother texture.
Pistachio Pudding Mix: It adds the festive green color and a minty flavor. If you can’t find pistachio pudding, vanilla or mint pudding work well too. Just add a few drops of green food coloring for that shamrock look.
Wafers or Vanilla Cookies: These create the “lasagna” layers and soften as they soak up the creamy filling. Graham crackers or even ladyfingers are great substitutes if you want a different texture.
Chocolate Sandwich Cookies: They add a nice crunch and chocolate flavor. Oreos are perfect, but feel free to use any chocolate sandwich cookies you like. Crushing them into chunks adds a nice texture contrast.
How Do You Layer This No-Bake Dessert to Get Perfect Texture?
Layering is key to this dessert’s success. Here’s how to do it right:
- Start with a thin layer of the cream cheese and pudding mix. This keeps the cookies from becoming soggy too fast.
- Add one even layer of wafers or cookies. Don’t overlap too much; cover the surface smoothly.
- Spread pistachio pudding and then sprinkle the chocolate cookie chunks to add flavor and crunch.
- Repeat layers carefully and finish with whipped topping on top for a light, airy finish.
- Chill for at least 4 hours—this resting time softens the cookies and blends the flavors, making it taste better.
Equipment You’ll Need
- Mixing bowls – I use these to blend the cream cheese and pudding mixes easily.
- Electric hand or stand mixer – makes mixing smooth and quick, especially for softening the cream cheese and whipping the topping.
- Whisk – handy for mixing the pudding mix with milk to get a smooth, thick consistency.
- 9×13 inch dish – a common size for layering all the ingredients evenly.
- Spatula or spoon – helps spread and layer the creamy mixture smoothly.
- Decorating tools (like a piping bag or spoon) – useful for neat dollops of whipped topping and sprinkles on top.
Flavor Variations & Add-Ins
- Use vanilla or mint pudding instead of pistachio for different flavors while keeping the green theme.
- Add crushed peppermint candies or green M&Ms on top for a spiked minty crunch.
- Layer in fresh whipped cream or Greek yogurt for a lighter, fluffier texture.
- Mix chopped nuts like pistachios or almonds into the layers for extra crunch and flavor.
St. Patrick’s Day Shamrock Lasagna Dessert
Ingredients You’ll Need:
- 2 packages (8 oz each) cream cheese, softened
- 1/2 cup granulated sugar
- 1 teaspoon vanilla extract
- 1 container (8 oz) frozen whipped topping, thawed, divided
- 2 boxes (3.4 oz each) instant pistachio pudding mix
- 3 cups cold milk
- 1 package wafers or large thin vanilla cookies (like vanilla wafers or graham crackers)
- 6 oz chocolate sandwich cookies, crushed (for layering and topping)
- Green colored sugar or sprinkles (for garnish)

How Much Time Will You Need?
This dessert takes about 20–30 minutes to prepare, plus at least 4 hours in the fridge (overnight is best) to let the layers set and the cookies soften. The hands-on time is easy and quick, making it perfect for holiday gatherings or last-minute treats!
Step-by-Step Instructions:
1. Mix the Cream Cheese Layer:
In a large bowl, use a mixer to beat the softened cream cheese with granulated sugar and vanilla until smooth and creamy. Gently fold in 1 cup of the thawed whipped topping until blended evenly.
2. Prepare the Pistachio Pudding:
In another bowl, whisk the instant pistachio pudding mix with cold milk for about 2 minutes until it thickens. Then, fold half of this pudding into the cream cheese mixture to create a creamy green layer.
3. Assemble the First Layers:
Spread a thin, even layer of the cream cheese and pudding mix on the bottom of a 9×13 inch dish. Next, arrange a single layer of wafers or vanilla cookies to cover the cream layer.
4. Add Pudding and Cookies:
Spread half of the remaining pistachio pudding evenly over the cookie layer. Sprinkle half of the crushed chocolate sandwich cookies on top.
5. Build the Next Layers:
Cover the cookie crumbs with another layer of wafers or cookies. Spread the remaining cream cheese and pudding mixture evenly over this layer.
6. Finish with Whipped Topping and Decorations:
Top the entire dessert with the rest of the whipped topping. Decorate with dollops of whipped topping, remaining crushed chocolate cookies, green sugar sprinkles, and drizzle with chocolate syrup if you like.
7. Chill and Serve:
Refrigerate the assembled dessert for at least 4 hours or overnight so the cookies soak up the cream and pudding and the layers set well. When ready, cut into squares and enjoy your festive Shamrock Lasagna!
Can I Use Regular Pudding Instead of Pistachio?
Yes! You can substitute vanilla or mint-flavored instant pudding if pistachio isn’t available. Just add a few drops of green food coloring to keep that festive Shamrock look.
How Do I Store Leftovers?
Store leftovers covered tightly in the refrigerator for up to 3 days. The layers may soften over time, but the dessert will still taste delicious chilled.
Can I Make This Dessert Ahead of Time?
Absolutely! In fact, it tastes better after chilling overnight as the cookies soak up the creamy layers and flavors meld beautifully.
What Can I Use If I Don’t Have Whipped Topping?
You can use freshly whipped cream or a whipped cream substitute. Just make sure it’s light and fluffy to keep the dessert airy and delicious.
