In a medium saucepan, melt the butter in the water over medium-high heat. Once the butter is melted, reduce the heat to low and add the flour all at once. Stir vigorously with a wooden spoon until the mixture forms a ball and pulls away from the sides of the pan. Remove from heat.
Add the eggs, one at a time, to the dough and mix until completely combined. Add the sugar, almond extract, and salt and mix until combined.

Bake for 30 minutes, or until golden brown. Let cool completely before filling.
In a medium bowl, mix together the heavy cream, confectioners' sugar, and vanilla extract until soft peaks form. Use a hand mixer or stand mixer for best results.
Transfer the cream to a pastry bag fitted with a large star tip. Pipe the cream into the cooled puff pastry ring, starting from the outside and working your way inwards. Serve immediately.
