Indulge in these chewy, wholesome bars packed with hearty rolled oats, creamy peanut butter, and rich chocolate chips. Each bite offers a perfect balance of nutty sweetness and satisfying texture, making it an ideal grab-and-go treat or a great potluck take-along.
These bars are a crowd-pleasing blend of comfort and flavor.
These cookie bars vanish in no time every time I make them. I call them “Triple Cookie Bars” because they are like a chocolate chip cookie, oatmeal cookie, and peanut butter cookie all in one.
