How do you make lilac buttercream?

To make lilac buttercream, start by beating together softened unsalted butter and powdered sugar until light and fluffy. Gradually add a few tablespoons of heavy cream and a few drops of lilac extract or natural lilac flavor, mixing until combined. For color, incorporate a small amount of purple food coloring, adjusting until you achieve the desired shade. Finally, mix until smooth and creamy, then use it to frost cakes or cupcakes.
