You will know that the sugar cookie bars are done when they are slightly brown around the bottom and edges. The top will be colorless, but the center should be set.
Be careful to measure the flour correctly otherwise the bars will get dry.
Using a sharp knife that is sprayed with non-stick cooking spray will help your knife glide through as you cut your bars.
It’s best not to use natural or homemade peanut butter as it can separate and lead to your bars being too oily. Make sure you find peanut butter that contains stabilizers instead.
