Peanut Butter S’mores Cake Cookies

Cookies, cookies and more cookies! These simple cake cookies are such a hit and couldn’t be easier to whip up. Once you have your s’mores toppings and a cake mix, you are just about good to go!

Let’s take a look shall we?


Here’s your line up!

One bowl folks, you can do this in your stand mixer if you prefer.

Add your cake ingredients to a large bowl.

I had my sweetie pie helping in the kitchen for these, what a treat!

He’s going to be quite the cookie maker when he gets older ๐Ÿ™‚

Almost time to stir!

Alright, here we go!

Wait until you try this dough, mmmm!

Place your cookie dough onto your baking sheet.

Flatten each cookie and top with mini marshmallows.

Oh yah!!

Top each with a Hershey Bar rectangle.

Top with graham cracker pieces and time to bake!

You get little bites of heaven when they come out!

You’ll love these bad boys.


Peanut Butter S’mores Cake Cookies

1 box Yellow Cake Mix

1 stick, (8 tablespoons) softened unsalted butter

1 large egg

1/2 cup creamy peanut butter

Two large Hershey Bars or 24 rectangles

Handfuls of mini marshmallows

Broken pieces of graham crackers

1. Preheat oven to 350 degrees F. and line a large baking sheet with parchment or a silpat liner.

2. Place the cake mix, butter, egg and peanut butter into a large bowl, mixing to combine. I find it easier to use my hands towards the end.

3. Scoop dough with a medium scoop and place onto prepared baking sheet 1 inch apart. Flatten each cookie to 1/2 inch thick and top each with a Hershey bar rectangle, some marshmallows and some graham cracker pieces. Bake for 12-15 minutes, until cooked through. Let cool for 10 minutes on baking sheet before transferring to cooling rack. Serve and enjoy!

Makes about 2 dozen cookies


Have a great day! Come back soon ๐Ÿ™‚

    Your little helper is just adorable. I’m sure he enjoyed the delicious treats he helped make!

    What a great idea! I love how the cookies stat with a cake mix. Every baker needs a secret dressed up cake mix in their recipe collection. My favorite is a pound cake mix…it is just about as versatile as a yellow cake mix.

    Is it wrong I want to put marshmallow ice cream between two of these and make an ice cream sandwich?

  22. 22

    this just looks so yummy… your kiddies are so adorable. i’ve never baked with marshmallow, can you believe that?

  23. 23

    What a fun treat! Perfect for getting help from little hands. These would be so fun to take camping!

    These are so creative and look incredibly delicious – I’m going to make them today. I have some graham cracker crumbs in my pantry, so I’m going to try rolling the dough in the crumbs before baking them. I love your site Jenny, thanks for sharing all your creations. Can’t wait to add your cookbook to my collection.
