Preheat oven to 400°F. Line a baking sheet with parchment paper.
Unroll the puff pastry and using a biscuit cutter cut 12 circles measuring 3 inches wide. Make sure to only press down with the biscuit cutter (don't turn) to cut the circles.
Place cirlces on the baking sheet, lined with parchment, leaving space between them. Bake 15–16 minutes until puffed and golden brown.
Remove from oven, let cool for a couple of minutes, then slice each pastry in half horizontally while still warm.
Return the halves to the oven, cut side up, and bake 1 - 2 more minutes. This dries the interior and prevents soggy cream puffs.
Cool completely on a wire rack. These may look underwhelming. Keep in mind they are the edible containers for whipped cream and strawberries - Mmmmm.
Right before serving, spray whipped cream onto the bottom half of each pastry shell.
Add sliced strawberries over the whipped cream.
Place the top pastry layer over the filling and dust lightly with powdered sugar if desired.
Serve immediately. Have napkins available. It gets a little messy!
