Avoid Common Mistakes & Follow Pro Tips for Baking Success

Mistakes to Avoid
1. Using cold ingredients can affect the mixing process. Always ensure your cream cheese is softened for a smooth frosting.

Tips for Success
1. For a richer flavor, add a pinch of salt to the peanut butter mixture; it enhances the taste!
