How to Make It
Microwave caramel candies and 1 Tbsp. heavy cream in a microwave-safe bowl on HIGH until mixture is smooth and melted, about 1 minute, stirring at 3-second intervals. Stir in 1 additional Tbsp. cream. Cool at room temperature until lukewarm, about 30 minutes. Beat softened butter and cream cheese with an electric mixer on medium speed until creamy; add vanilla and salt; beat until combined. Gradually add powdered sugar alternately with caramel mixture, beating on low speed until blended after each addition. Add 1 Tbsp. cream, 1 tsp. at a time, to reach desired consistency, if needed.
