Making A Big Chocolate Chip Cookie In A Slow Cooker Anyone that knows me, knows how much I LOVE homemade chocolate chip cookies. I don't need a reason to have one...or a dozen but I take one if there is one to be had. Saturday, May 15th is National Chocolate Chip Day but what good are chocolate chips if you can't bake them into a cookie? It's a tie for who makes the best cookies that I've ever had between Cookie Chris and my Mom, Donna. So I think that should be a tie-breaker between them and the only way to settle it is for them to have a cook-off and let me be the judge.
