Melt White Chocolate: In a double boiler or microwave-safe bowl, melt the white chocolate chips until smooth. Allow it to cool slightly.
Cream Butter and Sugar: In a mixing bowl, cream together the softened butter and confectioners' sugar until light and fluffy.
Incorporate White Chocolate: Gradually add the melted white chocolate to the butter and sugar mixture, beating until well combined.
Add Vanilla and Salt: Mix in the vanilla extract and a pinch of salt. These ingredients enhance the flavor and balance the sweetness.
Adjust Consistency: If the frosting is too thick, add heavy cream one tablespoon at a time until reaching the desired consistency. Ensure it's smooth and easily spreadable.
