Mason jars are still all the rave, and I love that this cookie company has used them in a fun and cute way! The Mason Jar Cookie Company sells mason jars filled with all the ingredients to make delicious cookies, and all you need to add is a few additional ingredients like eggs or butter. I made a video of my review, baking, and tasting the cookies. Absolutely scrumptious! They were nice enough to offer a free jar with cookie batter to one lucky subscriber! Check it out and enter! Good luck!
