Don’t Want To Use Cool Whip? Make Homemade Whipped Cream: To substitute for an 8-ounce tub of Cool Whip, combine 1.5 cups of heavy cream (or heavy whipping cream) and 1/3 cup powdered sugar in a mixing bowl. Using an electric hand mixer or the whisk attachment on a stand mixer, beat until stiff peaks form. This should take about 4-5 minutes. Start at a low speed to avoid splashing, and gradually increase the speed as the cream thickens.
