Bake at 400°F (200°C) for 25–30 minutes, or until the cream puffs are puffed, golden brown, and firm.
Do not open the oven during baking. Once done, remove and allow them to cool completely on a wire rack.
Prepare the Cream Filling
In a large bowl, beat the heavy cream, powdered sugar, and vanilla extract until stiff peaks form.
Fill the Cream Puffs
Slice each cream puff in half or create a small opening on the side. Fill generously with whipped cream using a spoon or piping bag.
