Preparation Steps

• In a saucepan, combine the sweetened condensed milk and butter. Cook over low heat, stirring constantly, until the butter is melted and the mixture is smooth. Do not boil.
• Remove from heat and stir in the vanilla extract and heavy cream. Let the mixture cool completely to room temperature, then refrigerate until chilled but not solid.
• In a large bowl, beat the chilled mixture with an electric mixer on high speed until light and fluffy, about 5-7 minutes.
• Use immediately for frosting cakes or cupcakes.
