How I created this Peanut Butter Cookie S’more Cake recipe

I am obsessed with this cookie cake. It’s seriously crazy messy and oh so good (Most messy things are quite delicious!) DANG so good!

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 the marshmallow set a bit before stacking.

Look at that slice! GAH drooling over here, so hard to write these posts after the food is already gone!

I’m going to make it in tart form next time – cause who doesn’t need a tart version of this with EXTRA marshmallow fluff and more chocolate? So tell me – what’s YOU favorite way to eat s’mores?

Tips to Make the Perfect S’more Peanut Butter Cookie Cake

First step is picking your size – I’d stick with 6 inches or smaller for this. The heaviness of the cookies and the lightness of the marshmallow frosting fight with each other, any bigger and the filling will squish out

Baking the cookies – don’t go too thick or it will take too long to bake, too thin and the cookie could break. I found that about 1/3 of inch of batter was perfect for me

Ganache – For this I use a 2 to 1 ratio – it’s great for that thick filling between the layers, but it’s a little too thick for a pretty drip. If I was going to make it again I’d add a little extra hot cream before the final layer to get prettier drips.

Marshmallow frosting – This is never a thick frosting, and it takes awhile to set, so I actually adding the ganache and the marshmallow topping to each layer, THEN stacked them after all 4 layers had a moment for the frosting to set – vs frosting and stacking while you go.

Finally toast the whole thing with a kitchen torch. I kept the torch further away to just get the edge colored, but you can torch as much or as little as you’d like.

To make this cookie cake you’ll need

• Good hand mixer or stand mixer – I use a Bosch
• 4 6-inch cake pans
• parchment circles
• Piping bags
• star tip
• kitchen torch
