Peanut Butter Oatmeal Bars are thick, soft cookie bars made ultra-easy with an oatmeal chocolate chip cookie mix boosted with extra oats, peanut butter, and cream for a rich, chewy texture. Baked in a 9×9 pan, they slice into dense, bakery-style squares packed with oats and chocolate in every bite.
Why these bars are so simple
Using a store-bought oatmeal chocolate chip cookie mix as the base skips creaming butter and measuring multiple dry ingredients, similar to other shortcut bar recipes that start from a mix. Rolled oats add chew and structure, while peanut butter and a splash of heavy cream enrich the dough so it bakes up fudgy and soft rather than dry.
Everything mixes in one bowl, presses into a single pan, and bakes at the familiar 350°F, like many peanut butter oatmeal cookie bar recipes that target golden edges and set centers.
