Shamrock Shake Lasagna Ingredients
For the Crust
• Oreos – Provides a crunchy base and classic chocolate flavor; substitute with gluten-free cookies for a gluten-free option.
• Butter – Acts as a binding agent for the Oreo crust; unsalted butter will keep flavors balanced.
For the Creamy Layers
• Cream Cheese – Adds richness and creaminess to the filling; for a lighter version, use low-fat cream cheese.
• Powdered Sugar – Sweetens the cream cheese mixture, giving it a smooth texture; can substitute with a sugar alternative for a diabetic-friendly version.
• Cool Whip – Contributes to lightness and creaminess in both layers; homemade whipped cream can be used as an alternative.
• Milk – Hydrates the pudding mix and adds creaminess; non-dairy milk can be used for vegan variations.
• Cheesecake Instant Pudding Mix – Provides structure and flavor to the middle layer; vanilla pudding can be substituted if cheesecake flavor is unavailable.
• Mint Extract – Enhances the minty flavor in the Shamrock Shake Lasagna; you can reduce the amount for a milder mint taste or replace it with peppermint extract for a stronger flavor.
• Green Gel Food Coloring – Adds a festive touch; omit for a classic look or substitute with natural green coloring if desired.
For Garnishing
• Crushed Oreos – Sprinkle on top for added crunch and visual appeal when serving.
• Mint Leaves – Garnish for a fresh touch and decoration on each slice.
Now that you have the ingredients ready, let’s get into the magical assembly of this delightful dessert!
Step‑by‑Step Instructions for Shamrock Shake Lasagna
Step 1: Preheat and Prepare the Dish
Start by preheating your oven to 375°F (190°C). While the oven is warming up, grab a 9 x 13 inch baking dish and generously spray it with non-stick cooking spray to prevent the dessert from sticking later on. This will ensure that your Shamrock Shake Lasagna is easy to slice and serve when it’s time for dessert.
Step 2: Create the Oreo Crust
In a food processor, crush enough Oreos to make a fine crumb. Once crushed, mix these crumbs with melted butter in a large bowl, stirring until the mixture resembles wet sand. Pour the mixture into the prepared baking dish, pressing it firmly into an even layer at the bottom. Bake the crust in the preheated oven for 8 minutes, then remove it and allow it to cool completely.
Step 3: Make the Cream Cheese Layer
In a mixing bowl, beat together softened cream cheese and powdered sugar until the mixture is smooth and creamy. Then, gently fold in one tub of Cool Whip until fully incorporated. The texture should be light and fluffy. Once the Oreo crust has cooled, spread this cream cheese mixture evenly over the crust, taking care to cover it completely for a beautiful layered effect in your Shamrock Shake Lasagna.
Step 4: Prepare the Minty Pudding Layer
In another bowl, whisk together milk and the cheesecake instant pudding mix until the mixture thickens, about 2 minutes. Next, fold in the second tub of Cool Whip, making sure to combine everything well. Add a splash of mint extract to enhance the flavor, and if desired, a few drops of green food coloring to achieve a festive mint hue. Mix gently until the color is uniform, and the cream is airy.
Step 5: Assemble the Lasagna
Once your minty pudding is ready, carefully spread it over the cream cheese layer. Use a spatula to create a smooth and even layer, ensuring every bite of your Shamrock Shake Lasagna will be minty and delightful. The contrasting colors will create a visually pleasing presentation, perfect for any occasion!
Step 6: Final Touches Before Serving
To finish off your Shamrock Shake Lasagna, sprinkle crushed Oreos generously on top of the mint layer for added crunch and flavor. Refrigerate the dessert for at least 4 hours, or until it’s set, allowing the flavors to meld together beautifully. When ready to serve, slice into squares and consider garnishing each piece with fresh mint leaves for a touch of elegance!

Thawing: To enjoy frozen lasagna, transfer it to the fridge overnight to thaw. Avoid microwave thawing to maintain texture, and serve chilled.

Make Ahead Options
These Shamrock Shake Lasagna layers are perfect for meal prep enthusiasts!

Shamrock Shake Lasagna Recipe FAQs
How do I choose perfectly ripe ingredients for my Shamrock Shake Lasagna?
Absolutely! For the best results, select fresh and high-quality ingredients. Ensure your cream cheese is at room temperature for easy blending, and check that your Cool Whip is fully thawed to avoid lumps. Fresh mint leaves should be vibrant and fragrant, signaling their quality—and don’t forget to use Oreos that aren’t stale!
What’s the best way to store leftover Shamrock Shake Lasagna?
Store leftover Shamrock Shake Lasagna in an airtight container in the refrigerator for up to 3 days. Keeping it sealed helps maintain the texture and prevent any unwanted odors from affecting your delightful dessert. It’s best enjoyed fresh within the first 24 hours, but I promise it will still be delicious for a few days!
Can I freeze Shamrock Shake Lasagna? How?
Yes, you can freeze it! Wrap individual servings tightly in plastic wrap and then place them in a freezer-safe container. This protects them from freezer burn and allows you to enjoy them later. The dessert can be frozen for up to 2 months. To thaw, simply move the lasagna to the fridge overnight before serving. Avoid using the microwave, as it can alter the creamy texture.
What should I do if my layers aren’t setting properly?
If your layers aren’t setting as they should, ensure that your pudding mix is mixed thoroughly with the milk for the correct thickness before folding in the Cool Whip. For a more stable layer, give the dessert extra time in the fridge—at least 4 hours—for it to set properly. Remember, patience is key when it comes to no-bake desserts!
Are there any dietary considerations I should keep in mind?
Very! This Shamrock Shake Lasagna can easily accommodate various dietary needs. For gluten-free options, substitute Oreos with gluten-free cookies. For a lighter version, use low-fat cream cheese and sugar alternatives for the powdered sugar. If you’re making it vegan, swap the cream cheese and Cool Whip for plant-based versions and use non-dairy milk. There’s always room for everyone at this dessert table!
Can I make any substitutions for the mint flavor?
Definitely! If you prefer a different mint flavor, you can substitute mint extract with peppermint extract for a more robust kick. If you’d rather skip the mint entirely, try adding flavored pudding mixes—chocolate or vanilla work beautifully and create a unique dish. The more variations, the merrier your experience!
