The Origin of St. Patrick’s Day

St. Patrick’s Day, observed on March 17th, commemorates St. Patrick, the patron saint of Ireland. What began as a religious observance has grown into a broader celebration of Irish culture and heritage, especially in the United States. Parades, music, and festive green foods are all part of how people honor the day and enjoy seasonal treats like this dessert.

Ingredients You Will Need

• Layer 1: Cookie Crust
  • 24 Oreo cookies, crushed (about 2 sleeves)
  • 6 tablespoons salted butter, melted
• Layer 2: Cheesecake Layer
  • 8 ounces cream cheese, softened to room temperature
  • 1/4 cup granulated sugar
  • 1 teaspoon pure peppermint extract
  • 8 ounces Cool Whip original whipped topping, thawed
• Layer 3: Pudding Layer
  • 3.4 ounces Jell-O vanilla instant pudding (1 package)
  • 1 3/4 cups cold milk
  • 1 teaspoon mint extract
  • Green food coloring (a few drops, adjust to desired color)
• Topping
  • 8 ounces Cool Whip extra creamy whipped topping, thawed
  • 1/4 cup miniature chocolate chips (optional)
  • Green candy sprinkles (for decoration, optional)

Instructions

This no-bake dessert has several layers, but the steps are straightforward and assemble quickly.

1. Make the crust. Crush 24 Oreo cookies in a food processor until fine crumbs. If you don’t have a processor, place the cookies in a strong resealable bag and crush them with a rolling pin. Mix the crumbs with 6 tablespoons melted salted butter and press the mixture firmly into the bottom of a 9×13-inch baking dish to form an even crust. Refrigerate while preparing the next layer.
2. Prepare the cheesecake layer. In a mixing bowl, beat 8 ounces softened cream cheese with 1/4 cup granulated sugar and 1 teaspoon peppermint extract until smooth and creamy. Gently fold in 8 ounces thawed Cool Whip until the mixture is light and uniform. Spread this cheesecake mixture evenly over the chilled cookie crust. Return to the refrigerator.

   

3. Make the pudding layer. In a separate bowl, whisk together the 3.4-ounce package of vanilla instant pudding with 1 3/4 cups cold milk, 1 teaspoon mint extract, and a few drops of green food coloring. Use a hand mixer to whip until the pudding thickens, about 3–5 minutes. Carefully spread the pudding over the cheesecake layer in the baking dish. Chill the assembled dessert for at least three hours to let the layers set.

   

4. Finish with topping. Once the dessert is firmly set, spread 8 ounces of thawed Cool Whip extra creamy evenly over the pudding layer. Sprinkle with 1/4 cup miniature chocolate chips and green candy sprinkles for a festive look. Keep refrigerated until ready to serve.

   

Lastly

After decorating, chill until serving. Slice into squares and serve cold. The layered presentation makes a striking, minty dessert that’s easy to share.
