Step 1: Prepare the Crust - Pulse chocolate sandwich cookies until fine crumbs. Mix with melted butter and press into a 9x13-inch dish.

Step 2: Make the Cream Cheese Layer - Beat softened cream cheese with powdered sugar until smooth. Fold in whipped topping and spread over the crust.

Step 3: Add Fruit Layers - Spoon strawberry pie filling over cream cheese, followed by blueberry pie filling, creating layers that contrast beautifully.

Step 4: Finish with Topping - Dollop remaining whipped topping on blueberry filling and sprinkle with star-shaped sprinkles. Refrigerate for at least 4 hours.
