Begin by creaming softened butter until it's light and fluffy.
Gradually add powdered sugar, mixing until fully incorporated and the mixture is smooth.
Incorporating Fruit: Add the fruit puree or jam a little at a time, ensuring it's thoroughly mixed into the buttercream.
Adjust the amount based on taste and desired consistency.
Final Touch: Continue mixing until the Fruit Buttercream reaches a spreadable or pipeable texture.
Refrigerate briefly if it needs to firm up before use.
