Preheat oven to 400°F. Line two baking sheets with parchment paper.

In a medium saucepan, combine water, butter, and salt over medium heat. Bring to a rolling boil.

Remove from heat and add flour all at once. Stir vigorously until mixture forms a smooth ball.

Let dough cool 5 minutes. Add eggs one at a time, beating well after each addition until glossy.

Drop rounded tablespoons of dough onto baking sheets, spacing 2 inches apart. Shape into hearts if desired.

Bake for 25-30 minutes until golden brown and puffed. Don't open oven door during first 20 minutes.

Turn off oven and let puffs cool inside with door slightly ajar for 10 minutes.

Whip heavy cream, powdered sugar, and vanilla until stiff peaks form.

Toss sliced strawberries with granulated sugar and lemon juice. Let macerate 15 minutes.

Slice cooled puffs horizontally. Fill with whipped cream and strawberries. Dust with powdered sugar before serving.
