Step 1: Begin mixing cream
For each cup of heavy whipping cream add 1/4 cup powdered sugar.
Step 2: Whip cream
While whipping, add 1 tsp of vanilla for each cup of cream.
Continue whipping until cream is almost firm. Serve immediately.
If you let your whipped cream sit too long before serving, it may get liquidy again. Just give it a quick whip and serve.
