12 Days of Treats Cookies

Monster Cookies

Whether you call them monster cookies or cowboy cookies, you can definitely call them delicious!  Actually, I call them “end of season cookies” because I use open bags of ingredients so the recipe always changes a little for me.  You know how you use butterscotch or peanut butter chips for one random recipe, then a few different kinds of chocolate chips for others.  This cookie lets you ensure you have no food waste so they’re kind of saving the planet.  😉  These ooey, gooey goodies have quickly become a favorite for those who request treats as their holiday gift from me.

Sur La TableThese Monster cookies are seriously one of the best cookies ever.  It is so customizable to your taste that you could make this cookie 20x and never have the same batch twice.  Of course, I’m sure that you’ll have fun finding your favorite combo.  The video shows you how to bring it all together and what the recipe should look like in different stages.
