Heat the oven to 400 degrees and line a baking sheet with parchment paper.
Slice the puff pastry into 6 rectangles. Using a fork, poke holes all over the pastry dough. Line up on a baking sheet and place another piece of parchment paper on top. Place a second baking sheet on top of the pastry dough and bake for 23 minutes. Remove and allow to cool.
Meanwhile, slice the strawberries into a bowl, add the vinegar and sugar and stir to combine. Set aside.
Using a hand mixer or whisk, whisk the cream until peaks are beginning to form, add the powdered sugar and beat for another second or two until it's sweetened the cream and peaks hang down when you lift the beaters.
To assemble, place strawberries on one pastry sheet, top with whipped cream, another pastry sheet and a little extra cream on top. Enjoy!
