If you’ve never tried monster cookies before, you have to give this fun and easy recipe a whirl. My monster cookies are chewy, sweet and full of yummy surprises.

Not that I put everything off until the last minute or anything. No way… not me! :)

I like monster cookies because you just really can’t go wrong when making them. They always look a little thrown-together and messy, and I’m totally okay with that. The most important thing is that they are full of good stuff on the inside.
You know, I think the monster cookie is a metaphor for my life. Haha!

I think I’ve mentioned once or a dozen times before, but I’m a pretty big fan of peanut butter. Any type of peanut butter cookies is a winner in my book.
