  • 1 tsp mint extract
  • Green gel food coloring (adjust for desired shade)

Kitchen Equipment Needed

  • 9×13 inch baking pan

How to Make Shamrock Shake Dessert Lasagna

Step 1:

Preheat your oven to 375°F (190°C). Grease or spray a 9×13-inch pan with non-stick spray.

Step 2:

Crush the Oreos finely using a food processor or by placing them in a sealed plastic bag and crushing with a rolling pin.

Step 3:

Pour the melted butter over the crushed Oreos and stir or pulse until well combined.

Step 4:

Press the Oreo mixture firmly and evenly into the bottom of the prepared pan.

Step 5:

Bake the crust for 8 minutes, then remove from oven and allow it to cool completely.

Step 6:

In a large bowl, beat together the softened cream cheese, powdered sugar, and one tub (8 oz) of Cool Whip until smooth.

Step 7:

Spread this cream cheese mixture evenly over the cooled Oreo crust.

Step 8:

In a separate large bowl, whisk together the milk and cheesecake pudding mix according to package instructions.

Step 9:

Fold in the remaining 8 oz tub of Cool Whip and the mint extract.

Step 10:

Add green gel food coloring a few drops at a time, mixing until you reach the desired shade.

Step 11:

Spread the mint pudding mixture evenly on top of the cream cheese layer.

Step 12:

Optional: sprinkle additional crushed Oreos on top for garnish.

Step 13:

Refrigerate for at least 2 hours or until set before slicing and serving.

Some Tips!

  • Use softened cream cheese to ensure a smooth cream cheese layer without lumps.
  • Be patient with the crust cooling completely before adding the cream cheese layer to prevent melting.
  • Feel free to adjust the amount of mint extract to match your family’s taste preference.
  • For a dairy-free version, substitute Cool Whip and cream cheese with dairy-free alternatives.
  • If you don’t have green food coloring, you can skip it – the mint flavor shines through without the color!

How to Store Leftovers

Store any leftovers in an airtight container in the refrigerator. This dessert keeps well for up to 3 days, but for the freshest taste and texture, enjoy within 2 days. Avoid freezing as the layers may separate or change texture.
