Chill your mixing bowl and beaters in the refrigerator for about 10 minutes.

In the chilled bowl, pour in the heavy whipping cream. Add the powdered sugar and vanilla extract.

Using an electric mixer on medium speed, start whipping the mixture.

Gradually increase to high speed as the cream thickens, which should take about 3-5 minutes.

Continue whipping until soft peaks form.

If the frosting seems too thick, add a tablespoon of milk and mix briefly to incorporate.

Taste the frosting. If you prefer it sweeter, add more powdered sugar, one tablespoon at a time.

Use a spatula or piping bag to spread the frosting on your cooled cake.

Slice your cake and serve immediately.
