Can peanut butter cookies be made into bars?

When a reader asked if they could simply make my peanut butter cookie into bars, I was intrigued and wanted to try it out myself.

Unfortunately, they didn’t work out as well and the cookie bars came out too thick, brittle and fell apart when sliced, almost like cookie dough. 

Not all peanut butter cookies can be made into bars unless ingredients and proportions are altered.

Instead of simply using my basic peanut butter cookie recipe and making it into bar form, I started from scratch.

  • Fold in your chocolate chips, along with reserving a few to top the cookie bars with.
  • Bake the cookie bars until golden on the outside and a toothpick comes out ‘just’ clean from the center.
  • Allow the cookie bars to cool completely in the pan, before slicing up into bars

  2. Set aside for 10 minutes, until a gel is formed.

Storing peanut butter cookie bars

Can you keep these bars at room temperature? YES! These cookie bars can be stored at room temperature. Ensure they are either in a sealed container or on a plate covered in plastic wrap. They will keep at room temperature for up to 5 days. 

Can you refrigerate them? Cookie bars are best stored in the fridge, as they will keep longer and have a much chewier texture. Refrigerated cookie bars will keep for at least 2 weeks.

Can you freeze them? Peanut Butter Cookie bars are freezer friendly and can be stored in the freezer. Wrap each cookie bar individually in parchment paper and place in a ziplock or freezer bag. 

Serving tips

If enjoying a cookie bar from the freezer, allow thawing completely at room temperature.

For thick and chewy cookie bars- Enjoy either directly from the fridge. 

For soft and gooey cookie bars- Enjoy at room temperature, or heat up in the microwave or oven until warm and gooey. 

These cookie bars would also be perfect with a scoop of keto vanilla ice cream or keto chocolate ice cream or even crumbled over some keto oatmeal!
