In a medium chilled mixing bowl, pour in the 1 cup heavy cream, 1 tsp vanilla extract, and 2 tbsp icing sugar.
2 tbsp icing sugar, 1 tsp vanilla extract, 1 cup heavy cream
Begin whipping the cream using an electric mixer on low speed to fully combine all ingredients. Increase the mixer speed to high and continue whipping. Watch closely as the cream thickens, making sure not to overwhip. It should form stiff peaks that hold their shape.
Taste the whipped cream and adjust the sweetness or vanilla flavor if needed by adding more icing sugar or vanilla extract. Serve immediately.
