These delightful oatmeal and peanut butter chip cookie bars are made in just one batch.

Oatmeal, Peanut Butter Chips and Blueberry Cookie Bars on plate

Making cookie bars is so easy when compared to making regular cookies because the cookie bars are all made in one batch.

The cookie dough is spread right onto a large cookie sheet and then goes into the oven to bake.

After the cookie bars are done baking, they need to cool for a bit and then the fun part is to cut them with a pizza cutter.

And the best part is, no additional batches to bake.

About the Ingredients

These cookie bars are made with dried blueberries, oatmeal and peanut butter chips.

The dried blueberries are a little bit chewy which adds nice texture to each bite.
