01 - Toss sliced strawberries with granulated sugar in a bowl. Let sit for 10-15 minutes until they release their juices, creating a macerated fruit layer.
02 - Beat cream cheese, powdered sugar, and vanilla extract in a large bowl until completely smooth and creamy.
03 - In a separate bowl, whip cold heavy cream until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture until fully incorporated and smooth.
04 - Line the bottom of a 9 x 9 inch square dish with half of the shortbread cookies, arranging them in a single layer.
05 - Spread half the cream mixture evenly over the cookie base. Top with half of the macerated strawberries, including their released juices.
06 - Create a second layer with remaining cookies, followed by the remaining cream mixture, and finish with the rest of the strawberries and juices.
07 - Cover the dish tightly with plastic wrap and refrigerate for at least 2 hours, or preferably overnight, to allow flavors to meld and cookies to soften to a cake-like texture.
08 - Garnish with additional fresh strawberries if desired. Slice into squares and serve chilled for best texture and flavor.
