🛒 Ingredients You’ll Need
This layered dessert comes together with simple, easy-to-find ingredients:
For the Oreo Crust:
- 36 Oreos, finely crushed
- 1 stick unsalted butter, melted
For the Cream Cheese Layer:
- 8 oz block cream cheese, softened
- 1 cup powdered sugar
- 1 tub (8 oz) frozen whipped topping, thawed
For the Mint Pudding Layer:
- 3 boxes (3.4 oz each) cheesecake instant pudding mix
- 3 cups cold milk
- 1 teaspoon mint extract
- Green gel food coloring (not drops)
- 1 tub (8 oz) frozen whipped topping, thawed
Garnishing:
- Oreo crumbs
- Extra whipped topping
- Maraschino cherries
- Green sprinkles
🍪 Step 1: Make the Oreo Crust
The crust is the rich, chocolatey base that holds everything together.
- Finely crush 36 Oreos using a food processor or sealed bag and rolling pin.
- Mix the crumbs with melted butter until evenly coated.
- Press firmly into the bottom of a 9×13-inch baking dish.
- Chill in the refrigerator for at least 20 minutes to set.
Pro Tip: Press the crust down firmly using the bottom of a measuring cup to prevent crumbling later.
🧀 Step 2: Prepare the Cream Cheese Layer
This layer adds a smooth, tangy contrast to the sweet mint pudding.
- Beat softened cream cheese until smooth and fluffy.
- Add powdered sugar and mix until fully combined.
- Fold in one tub of whipped topping gently to keep it light and airy.
- Spread evenly over the chilled Oreo crust.
- Return to refrigerator while preparing the next layer.
This creamy layer gives the dessert a cheesecake-like richness that balances the mint flavor beautifully.
🍮 Step 3: Make the Mint Pudding Layer
Now comes the fun part — the festive green mint layer.
- In a large bowl, whisk together pudding mix and cold milk for about 2 minutes.
- Add mint extract and mix well.
- Add green gel food coloring a little at a time until you achieve your desired shamrock shade.
- Fold in the second tub of whipped topping.
- Spread evenly over the cream cheese layer.
Important: Use gel food coloring, not liquid drops. Gel gives vibrant color without thinning the pudding.
❄️ Step 4: Chill and Set
Refrigerate the dessert for at least 4 hours (overnight is best).
This allows:
- Layers to firm up
- Flavors to blend together
- Clean slices when serving
Patience makes a big difference in texture and presentation.
🎉 Step 5: Garnish Like a Pro
Right before serving, decorate the top with:
- Oreo crumbs for texture
- Dollops of whipped topping
- Bright maraschino cherries
- Green sprinkles for extra festivity
You can even add chocolate shavings or mint candies for extra flair.
