To make enough whipped cream for a 9-inch pie, Ameden uses a cup of heavy cream (or whipping cream), 3 tablespoons of confectioner's sugar, and ¾ teaspoon of vanilla extract. Add all ingredients to a 12-ounce mason jar, and agitate it for 60-90 seconds or until you achieve the desired texture; for best results, use quality, high-fat cream, and chill until ready to serve.
