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 mixture.
02 - Beat cream cheese, powdered sugar, and vanilla extract in a large bowl until completely smooth and no lumps remain.
03 - In a separate chilled 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 even layer.
05 - Spread half of the cream mixture evenly over the cookie base. Top with half of the macerated strawberries, including their juices.
06 - Repeat the layering process with remaining cookies, cream mixture, and strawberries. Finish with strawberries on top.
07 - Cover the dish tightly with plastic wrap. Refrigerate for at least 2 hours, or overnight, to allow cookies to soften and flavors to meld together.
08 - Garnish with additional fresh strawberries if desired. Slice into squares and serve cold directly from the refrigerator.
