Place the cookies in the food processor and grind up until they resemble coarse crumbs. Add the melted butter and pulse until mixed together.
Press the crust mixture into the bottom and sides of a 10-inch tart pan. Use your hands to press it down firmly.
In a medium bowl, mix the ½ cup of cream cheese, ½ cup of sifted confectioner's sugar, and ½ cup of whipped topping. Mix on medium speed until smooth.
Spread the cream cheese mixture over the cookie crust.
Top with the remaining whipped topping and use a spatula to smooth it out.
Arrange the berries on top in the design of your choice.
Refrigerate for at least an hour before serving.
