S’more Peanut Butter Cookie Cake

Alright… I have been obsessed with this cake all summer and dying to share it with you – Layers of the BEST peanut butter cookie with Chocolate ganache and Marshmallow fluff frosting! DANG so good! NO SERIOUSLY, crazy messy but so good (remember these peanut butter s’more cookies? like that but BETTER)

I mean really – Peanut butter cookies are already a given, so good. And S’mores? come on, by far one of the most amazing food groups I swear! and together… in CAKE FORM! I die, seriously I’m making it AGAIN for my birthday next month!

So the FIRST time I made this cake I got ambitious and made it 8 inches, with thick cookies and gobs of marshmallow fluff… and the weight of it was insane and the marshmallow fluff couldn’t hold it and it totally cracked and collapsed! BUT it was still delicious, I lived off of the mess for a few days! so this time around I made 6 inch cookies, and used less marshmallow fluff frosting, also let them set a bit before stacking!
