Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

In a medium saucepan, combine 1 cup of water and ½ cup of unsalted butter over medium heat and stir until the butter melts.

Bring the mixture to a rolling boil, then quickly add 1 cup of all-purpose flour and ¼ teaspoon of salt.

Stir vigorously until the mixture forms a cohesive ball.

Let the dough cool for 5 minutes, then mix in 4 large eggs one at a time until smooth.

Spoon or pipe the dough into squares on the baking sheet, spaced 2 inches apart.

Bake for 25 minutes until golden brown and puffed.

Whip together 1 cup of heavy cream, 2 tablespoons of powdered sugar, and 1 teaspoon of vanilla extract until soft peaks form.

Cut cooled pastry squares in half, fill with whipped cream, and top with sliced strawberries.

Replace the tops and dust with powdered sugar if desired, then serve.
