Ingredients
The Crust
- 1 package (15.25 oz) Mint Oreo Cookies
- 6 Tbsp Unsalted Butter, melted
The Mint Cream Cheese Layer
- 1 package (8 oz) Cream Cheese, softened
- 1 cup Powdered Sugar
- 1 tsp Peppermint Extract
- 2–3 drops Green Gel Food Coloring
- 1 container (8 oz) Whipped Topping (like Cool Whip), thawed
The Pudding Layer
- 2 packages (3.9 oz each) Instant Chocolate Pudding Mix
- 3 cups Cold Whole Milk
The Topping
- 1 container (8 oz) Whipped Topping (like Cool Whip), thawed
- Garnish: Extra crushed Mint Oreos, green sprinkles, or chocolate shavings
Instructions
1. Prepare the Crust
Crush the entire package of Mint Oreos into fine crumbs using a food processor. In a medium bowl, combine the crumbs with the melted butter. Press the mixture firmly into the bottom of a 9×13-inch baking dish. Place in the freezer for 10 minutes to set.
2. Mix the Mint Layer
In a large bowl, beat the softened cream cheese and powdered sugar until smooth. Stir in the peppermint extract and green food coloring until you reach your desired “shamrock” green. Fold in one container of whipped topping. Spread this evenly over the chilled crust.
3. Whip Up the Pudding
In a separate bowl, whisk together the two packages of instant chocolate pudding and the cold milk for 2 minutes until thickened. Spread the chocolate pudding over the mint layer.
4. Add the Final Topping
Carefully spread the remaining container of whipped topping over the chocolate layer.

5. Chill and Garnish
Refrigerate for at least 4 hours (overnight is best) to allow the layers to firm up. Just before serving, sprinkle with crushed Oreos and festive green sprinkles.
Expert Tips for Success
- Gel Over Liquid: Use gel food coloring for the mint layer. It provides a more vibrant green without thinning out the cream cheese mixture.
- Softened Cream Cheese: Ensure your cream cheese is at true room temperature to avoid lumps in your green layer.
- Don’t Over-Milk: Notice we use 3 cups of milk instead of the 4 called for on the pudding boxes. This ensures the pudding is stiff enough to hold up the layers of the “lasagna.”
- Clean Slices: For perfect, restaurant-style squares, wipe your knife clean with a warm cloth between every single cut.

- Thin Mint Twist: Use crushed Girl Scout Thin Mint cookies for the crust instead of Oreos.
- Boozy Lasagna: Stir 2 tablespoons of Crème de Menthe into the cream cheese layer for an adult-only version.
- Individual Jars: Assemble the layers in mini mason jars for portable, single-serving party treats.

FAQ: Shamrock Lasagna
Q: Can I use real whipped cream? A: You can, but stabilized whipped topping (like Cool Whip) holds its shape much longer in the refrigerator. If using real whipped cream, be sure to stabilize it with gelatin or mascarpone.
Q: How long does this last? A: Store covered in the refrigerator for up to 4–5 days. The crust will soften slightly over time, but it remains delicious.
Q: Can I freeze shamrock lasagna? A: Yes! This dessert freezes beautifully. You can serve it partially frozen for a “semi-freddo” texture that is very refreshing.
Q: Why are my layers mixing together? A: This usually happens if the layers aren’t chilled enough before adding the next one. If you’re worried, pop the dish in the freezer for 15 minutes between each layer.
