Have ready an 8 or 9-inch glass or ceramic dish.
In a bowl beat 1 cup cream with ¼ cup powdered sugar until medium peaks form. If making ahead reserve, covered, in the refrigerator.
Wash, dry, stem, and dice ⅔ of the total amount of strawberries. Reserve.
Put a thin layer of cream in the bottom of the pan.
Add a layer of graham crackers, covering the bottom completely.
Top with half the amount of remaining cream, spreading evenly.
Now add the diced strawberries covering completely.
Top them with the rest of the cookies.
Add a layer of dulce de leche. You might need to be careful when spreading depending on the consistency as some are thicker than others.
Top the dulce de leche with the rest of the cream.
Cover the pan with plastic wrap and refrigerate for 1-2 hours.
Before serving, top with fresh strawberries.
Serve cold.
Keep covered in the refrigerator.
