Step 1: Beat Cream Cheese and Cookie Butter - Start by placing softened cream cheese and Biscoff cookie butter in an electric mixer or using a hand mixer. Beat them together until the mixture is smooth and creamy, ensuring you occasionally scrape down the sides and bottom of the bowl to incorporate all ingredients.

Step 2: Add Powdered Sugar - Gradually add powdered sugar to the creamy mixture, continuing to beat until everything is well combined and smooth. Make sure to scrape down the sides of the bowl again to ensure even mixing.

Step 3: Fold in Cool Whip - Once your mixture is smooth, remove it from the mixer and gently fold in the Cool Whip using a spatula. This step is crucial as it helps achieve that light, airy texture that makes this pie so special.

Step 4: Transfer Filling into Crust - Carefully transfer your fluffy filling into the prepared Biscoff pie crust, smoothing out the top with a spatula for an even finish. This ensures not only great presentation but also an evenly distributed filling.

Step 5: Chill Before Serving - Cover your pie with plastic wrap and place it in the refrigerator or freezer for about three hours. This chilling time allows the pie to set properly, making it easier to slice when ready to serve.
