I love Reese’s, and I love Monster Cookies. How could these two not team up?!?

Monster Cookies are, by far, one of my favorite treats of all time. My Grandma made them for every family event for as long as I can remember, and the nostalgia adds tremendously to the taste of these cookies for me.

Last year I went a little crazy post Monster Cookie recipes. Starting with the original recipe, of course.

Seriously. 2012 was all about the Monster Cookies in a BIG way. And since 2013 is rapidly becoming the year of Reese’s, it seems incredibly apropo to combine the two into one, great Reese’s Monster Cookie recipe! I have a feeling you are going to loooooove these cookies.

  1. Yes, yes, yes!! These cookies look so incredibly delicious! Monster cookies are a traditional summer cookie that my sister and I make at our lake cabin together and I cannot wait to share this version with her!

  2. Just a quick update – let the nieces and nephews in on my next baking project, Monster Cookis….I’m the favorite aunt! LOL! Thanks Ashton!

  3. Your “monster cookie” recipe looks phenoms! The dough might not make it into the oven it looks so amazing… I’m curious about the texture are they soft and chewy OR crunchy and hard?

  4. These look amazing and will be making them this weekend! I do have a question… the oats, are they instant or regular? What specific brand do you use? Thanks in advance and can’t wait to enjoy these!
