The BEST Peanut Butter Bar Recipe- The Perfect After School Treat

Do you guys remember in elementary school when you used to get homemade peanut butter bars? I sure do! We would get a bar and a carton of milk. I would always hope to get the biggest bar out of the group. Yes, they were that good. In today’s schools they don’t get these homemade bars anymore. They are pre-packaged treats that aren’t near as good. So, I’ve decided I need to make these as an after school treat for my kiddos. I found a recipe that I love. However, I’ve changed a few things and made a different frosting to make them absolutely delicious. I always get compliments on them. So thank you Six Sisters Stuff and Aunt Cindy for your recipes, because when you pair them together you get perfection.
