Preparation

• Place graham crackers and brown sugar in a food processor; process until fine crumbs form. With the processor running, pour in melted butter until the mixture resembles wet sand. Press into the bottom of an ungreased 13x9-in. baking dish. Cover; refrigerate at least 1 hour.
• Place softened cream cheese in the bowl of a stand mixer fitted with a paddle attachment; beat on medium speed until creamy and smooth, 2-3 minutes. Add in half of the whipped topping, confectioners’ sugar, vanilla extract and a pinch of salt. Mix on medium speed, scraping the bowl as needed, until blended into a smooth filling. Spread the filling in an even layer over the chilled crust.
• In a small bowl, combine blueberry filling and lemon juice; spread over the cream cheese filling. Spoon the remaining whipped topping over the blueberries; spread it into an even layer. Cover; refrigerate at least 4 hours or overnight.
• Before serving, garnish with fresh blueberries and graham cracker crumbs. Cut into squares to serve.
