As I assembled this six-layer dessert, I literally said “this is ridiculous” out loud.
And it’s true—these bars are utterly ridiculous. Peanut Butter Chocolate Chip S’Mores Bars are a fun, indulgent riff on s’mores. Think chocolate chip cookie bars, but with layers of goodness inside. You’ve got peanut butter, chocolate, graham cracker and marshmallow fluff in there. That all adds up to six insanely delicious layers.
The original recipe calls for store-bought dough, and you could certainly do that—there’s so much happening in these bars, you probably wouldn’t even notice the difference between store-bought and homemade dough. Still, I decided to make mine from scratch, and used the dough from my Gooey Chocolate Chip Fudge Bars. It worked out great: the dough was sturdy enough to keep the bars together, and the original recipe’s yield scaled perfectly to what the s’more bar recipe required. Whether you buy dough or make it, pay attention to measurements: you’ll need two 9×9 layers of dough to make this recipe work!
I was so excited to try these, and anxiously waited for the bars to cool so I could cut them up. My patience was definitely rewarded. Every bite of these bars is a trip down Delicious Lane. You get a bite of cookie, then a nice hit of chocolate, a spot of peanut butter, a spot of fluff…and more cookie. The graham cracker crumbs add a bit of texture, and help break up the fluff a bit.
My coworkers agreed that these bars were ridiculous, but in a totally amazing, have-to-eat-more way. We kept sneaking more bars from the kitchen all afternoon!
Peanut Butter Chocolate Chip S’Mores Bars
Yield: 25 bars
Suggested equipment: Mixer
Total Time: ~3 hours, including chill time
Cook Time: ~25 minutes
For the cookie dough
- 1 cup unsalted butter, softened
- 2/3 cup brown sugar
- 2/3 cup granulated sugar
- 2 eggs
- 1 tsp vanilla
- 1/2 tsp salt
- 1 1/2 tsp baking soda
- 2 1/3 cups flour
- 1 1/2 cups chocolate chips
- 4 standard Hershey chocolate bars (I used dark chocolate)
- 1 cup creamy peanut butter
- 5 graham crackers, crushed into crumbs
- 7 oz of marshmallow fluff (about 1 1/2 cups)
Make your dough
- Use your mixer to cream together the butter, brown sugar and granulated sugar until it’s light and creamy
- Add eggs, vanilla and salt, then mix well
- Add baking soda and flour. Mix until combined
- Stir in your chocolate chips
Assemble and bake
- Line and spray a 9×9 pan
- Take 1 1/4 of your cookie dough, and press it into the bottom of the prepared pan. Try to make the layer as smooth as you can
- Top your cookie dough with a single layer of chocolate bars
- Spread peanut butter on top of the chocolate. This might get tough: I ended up “finger-painting” with the peanut butter to make it work!
- Sprinkle your graham cracker crumbs on top of the chocolate
- Use a spoon to put dollops of fluff all over the graham crackers, then use an offset spatula to smooth it into a single layer
- Use your remaining cookie dough for the final layer. It’s easiest to just put bits of dough on the top, and then smooth them out with your fingers so it’s a single layer
- Bake for 22-25 minutes, until the top is golden. Mine took 24 minutes. It’s a little hard to tell if they’re done since there are so many layers…make sure to use a toothpick to test if the insides are baked through
- Allow the pan to cool for 2 hours on a wire rack. Then, transfer them to the fridge to cool completely.
- A little before you want to cut the bars, take them back out of the fridge. Use a shape knife to slice them up!
Note that these are a little tough to cut: it’s too hard when the bars are gooey, but also too hard to cut if they’re super chilled. So I suggest chilling them to let the bars set, but taking them out of the fridge about 30 minutes before you want to cut and serve.
These bars last nicely in an airtight container, and are best within 3 days of baking.
