Shamrock Shake Pie is a no-bake, minty dessert inspired by the iconic seasonal milkshake from McDonald’s. It features a creamy peppermint filling, a chocolate cookie crust, and a fluffy whipped topping—delivering the nostalgic flavor of a Shamrock Shake in sliceable pie form.

This dessert is ideal for St. Patrick’s Day, spring gatherings, or anytime you want a cool, refreshing treat without turning on the oven.

What Is Shamrock Shake Pie?

Shamrock Shake Pie transforms the classic mint-vanilla milkshake flavor into a structured, chilled dessert. Instead of a drinkable texture, the filling is stabilized using pudding and whipped topping, creating a mousse-like consistency that holds clean slices.

The defining characteristics are:

Bright mint flavor
Pale green color

Creamy texture
Chocolate contrast from the crust

Key Ingredient Spotlight

Peppermint extract provides the signature cool mint flavor. It is highly concentrated, so precise measurement is essential to avoid overpowering the filling.

Ingredients (Serves 8)

Crust

24 chocolate sandwich cookies (such as Oreos)
5 tablespoons unsalted butter, melted

Filling

1 package (3.4 oz) instant vanilla pudding mix

1 ½ cups cold milk
1 teaspoon peppermint extract
2–3 drops green food coloring (optional)

1 ½ cups whipped topping (Cool Whip or homemade stabilized whipped cream)

Topping

1 cup whipped topping
Chocolate shavings or crushed cookies (optional garnish)

Step-by-Step Instructions

1. Prepare the Crust

Crush chocolate sandwich cookies (including filling) into fine crumbs using a food processor or rolling pin.

Mix crumbs with melted butter until evenly combined.

Press firmly into a 9-inch pie dish, forming an even layer on the bottom and sides.

Refrigerate 20–30 minutes to set.

2. Make the Mint Filling

In a mixing bowl, whisk pudding mix and cold milk for 2 minutes until thickened.

Add peppermint extract and food coloring. Mix thoroughly.

Fold in whipped topping gently until fully combined and smooth.

Avoid overmixing to maintain light texture.

3. Assemble the Pie

Spread mint filling evenly into chilled crust.

Smooth the top with a spatula.

Refrigerate at least 4 hours (overnight preferred) until firm.

4. Add Final Topping

Before serving, spread or pipe additional whipped topping over the pie.

Garnish with chocolate shavings or crushed cookies if desired.
