St. Patrick’s Day Shamrock Lasagna Dessert is a fun and festive treat that layers green and white creams with crunchy cookies and a surprise hint of mint. The dessert looks like a playful lasagna but is actually sweet with creamy textures and a little bit of holiday luck in every bite.
I love making this dessert for St. Patrick’s Day gatherings because it’s easy to put together, and everyone gets a kick out of the shamrock shape on top. I usually sneak in some crushed mint candies or mint chocolate chips to give it a refreshing twist that really makes it special.
One of my favorite ways to serve it is chilled straight from the fridge, where the layers have had time to set and the flavors meld perfectly. It’s a crowd-pleaser that feels like a celebration on a plate, and I always look forward to seeing the smiles when it’s time for dessert!
Key Ingredients & Substitutions
Chocolate sandwich cookies: These form the crunchy base. Oreo or any similar chocolate cookie works well. If you need gluten-free, look for gluten-free chocolate sandwich cookies or crush gluten-free chocolate biscuits.
Cream cheese: This gives the dessert its creamy, tangy layer. Use full-fat for best texture; low-fat can make the filling less smooth. Soften it first to avoid lumps when mixing.
Peppermint extract: Adds a festive mint flavor. If you prefer, swap for mint chocolate chips inside the layers or use a mild mint syrup. Avoid too much extract—it’s strong and can overpower.
Heavy whipping cream: Whipping this to stiff peaks is key. You can substitute with a pre-made whipped topping, but fresh cream gives the best light, airy texture.
Green food coloring: Just a few drops to tint the mint layer green. If you want to keep it natural, try blending in a tiny bit of spinach juice or matcha powder for color but be careful as these can affect flavor.
Caramel sauce & Decorations: The caramel drizzle adds sweetness and a little richness. You can swap with chocolate sauce or leave it off if you want. Shamrock sprinkles are fun but optional—any green-themed topping works.
How Do I Get the Cream Layers Light and Smooth?
The cream layers are the heart of this dessert, and getting them smooth and light makes all the difference.
- Start by softening your cream cheese fully at room temperature for about 30 minutes before mixing.
- Beat the cream cheese well with powdered sugar until smooth; no lumps!
- Whip your heavy cream with granulated sugar to stiff peaks—when you lift the whisk, the cream should hold shapes without collapsing.
- Gently fold half the whipped cream into the cream cheese mixture. Use a spatula and fold carefully to keep the air in. Avoid stirring vigorously.
- Add green color gradually to get a soft minty shade, mixing gently.
These steps keep your layers fluffy and creamy, so when chilled, they hold together beautifully without being dense or heavy.
Equipment You’ll Need
- 8×8 inch square baking dish – I recommend this size to keep layers neat and manageable.
- Mixing bowls – for combining the crust, cream cheese, and whipped cream layers.
- Electric mixer or hand whisk – makes whipping the cream quick and easy.
- Spatula – helps to spread and layer the filling smoothly over the crust.
- Measuring cups and spoons – for accurate ingredients, especially the liquids and extracts.
- Garnishing tools (optional) – small toothpick or squeeze bottle for drizzling caramel, and a spoon for sprinkling sprinkles.
Flavor Variations & Add-Ins
- Chocolate Ganache: Pour a layer of melted chocolate on top or between layers for richer flavor.
- Mint Chips: Fold chocolate mint chips into the cream cheese layer for extra minty crunch.
- Coconut: Mix shredded coconut into the whipped topping for a tropical twist.
- Fruit Topping: Add sliced strawberries or cherries on top for a fresh, colorful touch.

How Much Time Will You Need?
This recipe takes about 20 minutes to prepare and assemble. After that, you’ll need to chill your dessert in the refrigerator for at least 4 hours (or overnight) so the layers can set well and the flavors can blend beautifully.
Step-by-Step Instructions:
1. Make the Crust:
Mix crushed chocolate sandwich cookies with melted butter until the crumbs are evenly coated. Press this mixture firmly into the bottom of an 8×8 inch baking dish to create the crust layer. Set aside.
2. Prepare the Mint Cream Layer:
Beat softened cream cheese until smooth. Add powdered sugar and peppermint extract, mixing until creamy. In a separate bowl, whip the heavy cream with granulated sugar until stiff peaks form. Gently fold half of the whipped cream into the cream cheese mixture. Stir in green food coloring to get a light green tint. Spread this mint cream mixture evenly over the cookie crust.
3. Layer and Top the Dessert:
Spread half of the remaining whipped topping over the mint cream layer. Add the rest of the whipped cream mixture as the next layer, spreading evenly. Sprinkle crushed chocolate candies or chips on top if desired. Drizzle caramel sauce over everything and finish by decorating with green shamrock sprinkles. Chill your dessert in the fridge for at least 4 hours, then cut into squares and serve cold!
Can I Use Frozen Whipped Topping Instead of Fresh Cream?
Yes, you can use store-bought whipped topping like Cool Whip for convenience. Just make sure it’s thawed before using and divide it as the recipe suggests to maintain the right texture and layering.
How Long Can I Store This Dessert?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Keep it chilled to preserve the creamy layers and the crunchy cookie crust.
Can I Make This Dessert Ahead of Time?
Absolutely! In fact, making it the day before helps the flavors meld and the layers set perfectly. Just keep it covered in the fridge until you’re ready to serve.
What If I Don’t Have Peppermint Extract?
No worries! You can omit the peppermint extract or substitute with a small amount of vanilla extract. Alternatively, add mint chocolate chips to keep the minty flavor without the extract.
