Tips
This is one of the easiest cookie recipes you'll ever make. That being said, there are a couple of things to remember to make them the best they can possibly be.
- When measuring flour, don't scoop directly from the container. Instead, spoon the flour loosely into the measuring cup and then level it off with a knife. This ensures the proper measure.
- Unlike flour, you want to pack your brown sugar extremely well when measuring it to ensure the proper measure.
- Be sure your cookies are completely cool before placing them in your container to prevent condensation.

I doubled the recipe, used 4 c of flour plus added 1 tsp of corn starch to the flour to help them tighten up a little. They were perfect!

These looked delicious. Can frozen rhubarb be used? Should it be thawed first? Will this effect consistency or cooking time? Your feedback would be appreciated.
Thanks!
Karin and Ken
I have never tried it but have always wanted to. I would defrost rhubarb in fridge or on counter and make sure it’s as dry as possible with paper towel. Then add it to recipe as if it were fresh. That’s what I would do. I’d love to hear your thoughts if you try this recipe! All the best. Karin
Caroline Sue Magruder-Raybin

Amazingly good!! Chewy with a crispy edge, sweet with a rhubarb zing, and perfect with a glass of milk or a mug of tea. We have a new family favorite!

My cookies didn't really get flat. Maybe it's because I had some big chunks of brown sugar that just wouldn't break down and I kept beating the first mixture trying to make them smaller? I enjoy a nice flat, crispy cookie, but these were quite puffy and soft. Very tasty though!
Karin and Ken
I’m glad you thought they were tasty. I’m sorry they’re not the type of cookie you’re looking for! Hopefully you find some other recipes on this site that you enjoy more! I try my best! Enjoy your day. Karin
Linda
Add a slice of bread to your brown sugar to soften it!!!
