In a food processor, pulse the cookies into crumbs. Add the brown sugar and melted butter; pulse to combine (the mixture should look like wet sand). If you don’t have a food processor, you can crush the cookies in a large Ziploc bag with a rolling pin, and then stir together the ingredients in a large bowl.
Press crumb mixture firmly into the bottom of a 9-inch square baking dish that’s been lightly sprayed with nonstick cooking spray. I use the flat bottom of a measuring cup to press the crumbs into an even layer, but your fingers work fine too. Refrigerate for at least 10 minutes while you prepare the filling.
MAKE THE FILLING
In a large bowl, use an electric mixer to combine the cream cheese, confectioners’ sugar, vanilla extract, and almond extract until smooth. Gently fold in the whipped topping.
LAYER THE DESSERT
Spread slightly less than half of the cream cheese mixture evenly on top of the chilled crust.
Drop blueberry pie filling in dollops on top of the cream cheese layer and spread evenly.
Top blueberry layer with the remaining cream cheese mixture to cover completely.
Sprinkle about ¼ cup of additional crushed cookie crumbs on top.
CHILL
Cover and refrigerate for at least 3 hours or overnight. Slice into squares and serve.
Notes
Start with a softened block of cream cheese. It’s easier to mix the cream cheese into a smooth filling when the cream cheese is at room temperature.
Remember to thaw the Cool Whip before using it in this recipe. Cool Whip must be thawed in the fridge for at least 4 hours — not on the counter at room temperature.
For a clean slice, wipe the knife with a paper towel or cloth after each cut.
This recipe yields 9 large squares. They’re quite rich, so you might prefer to slice them into 12 or 16 smaller pieces.
