Brown Butter Chocolate Chip Marshmallow Cookie Cake

cookie cake 5First thing I need to say is… this Sunday is Star Wars Day!!  You can be sure that I’ll have a post on all the goodies I’ll be making for this year next week.  Now back to the cookie cake, this cookie cake is everything I would want in a cookie: sweet, salty, crispy, chewy, marshmallow-y… I could go on about it.  The last time I served this was during this year’s Super Bowl and while people ate this, it was very quiet.  It was that good.
cookie cake 2To be honest, this recipe is like my baby.  This cookie recipe has been over 5 years in the making!  I almost didn’t want to write it down because well, it’s mine and I didn’t want to share.  But I figured someone must be having a day somewhere and this cookie would be sure to cheer them up.  So whip up a batch, and make yourself or someone smile because a smile is free therapy.

  1. Oh my gosh, this is incredible! I just showed it to my husband and we both can’t stop drooling. I love how tall the slices are–I could do some major damage on this cake!
