Cosmic Cuisine: Camp Half-Blood’s Campfire S’more Cookie Bombs

Share this:

In The Sun and The Star, we again return to Camp Half-Blood. Fans of Percy Jackson know that this summer camp is the place to be if you’re a demigod. And while, yeah, not everything about the camp is exactly like a mortal summer camp (monsters and demons pop up way too often), one thing remains the same at all camps: S’MORES! It just wouldn’t be camp without these gooey confections. And in The Sun and The Star, while Nico and Will are trekking through the Underworld to save their friend, thoughts of s’mores help to get them through. So I thought I would offer my own twist on these classic treats, with these S’more cookie bombs.

Admittedly messing with perfection is dangerous, but I gave it the old Camp Half-Blood try! I was very pleased with the results. I think you will be too.

Yield: 2 dozen

Total Time 1 hour 45 minutes


Sugar Cookies

  • 3/4 cups Butter
  • 1 cup Sugar
  • 2 Eggs
  • 1 tsp Vanilla
  • 2 1/2 cup Flour
  • 1 tsp Baking Powder
  • 1 tsp Salt

S'more ingredients

  • 3 Chocolate Bars (made of 12 squares of chocolate, possibly starting with an "H")
  • 6 Chocolate Peanutbutter cups (possibly starting with an "R")
  • 12 Marshmallows
  • 3 Tbsps Slivered Almonds
  • 1/2 cup Cocoa Powder
  • 4 Graham Crackers (crushed)
  • 1/2 cup Peanuts (chopped)


  1. Start by making the sugar cookie shells.
  2. Cream the sugar and butter together.
  3. Add the eggs and vanilla.
  4. In a separate bowl, mix the flour, baking powder, and salt.
  5. Add the flour mixture to the sugar mixture and mix until they just come together.
  6. Chill the dough for half an hour.
  7. While the dough is cooking, cut the marshmallows in half (or fourths if you want to limit the sugar), break the chocolate bars into individual squares, crush the graham crackers and chop the peanuts. Put the cocoa powder, peanuts, and graham crackers into small bowls.
  8. Once the dough is cooled, roll the dough on a well floured surface to 1/8" thickness and cut 48 2" circles.
  9. Take one circle and place 2 chocolate squares plus 1/2 a marshmallow on the circle.
  10. Place a second circle on top and completely seal the two cookies together, creating a sphere out of the dough.
  11. Roll the dough in cocoa powder and graham cracker crumbs.
  12. Place on a parchment paper lined tray with 3 inches between cookies (alternately, place cookies in lined muffin trays).
  13. For the peanutbutter cup s'mores, place a peanutbutter cup and half marshmallow on one circle. Place a second cookie on top and seal completely.
  14. Roll the peanutbutter s'more in cocoa powder and chopped peanuts, place on tray.
  15. For almond s'mores, include 1/2 Tbsp of slivered almonds with 2 squares of chocolate and 1/2 marshmallow. Top with a second cookies and seal.
  16. Roll in just cocoa powder, place on tray.
  17. Once all the cookies are assembled, place the trays in the freezer for 15 minutes.
  18. Now comes fun part. These cookies can be cooked three different ways. For the true campfire experience, cover individual cookies in aluminum foil and place on hot coals (not direct flames) for 15 minutes, let cool and enjoy.
  19. For a still amazing taste but slightly easier cooking, heat a grill to 350°F. Place a 9x13 pan upside down on the grill and place your baking sheet on top of this. Close the lid and bake for 15-20 minutes, until the cookies are done (tap with finger, there should be hardly any indent). Let cool and enjoy.
  20. Finally, these can be cooked in a regular oven that has been preheated to 350°F for 15-20 minutes. Cool and enjoy.

The original is perfection but s’more variations are always allowed

When it comes to s’mores, I’m honestly a classicist. Nothing will ever beat the taste of a perfectly golden marshmallow with melty chocolate sandwiched between two graham crackers. But I have dabbled with other combinations, and some of them were incorporated into this recipe (peanut butter cups or almonds anyone?).

I know some people who pair just about anything with a marshmallow and graham crackers and call it a s’more. So if you want a minty peppermint patty s’more bomb, or a dried cherries s’more bomb, or even a bacon s’more bomb (no judgment here) go for it! Make your s’more however you want. Approach this recipe with all the enthusiasm and contempt for rules (hehe) that any summer camp would admire! Just enjoy making them and spending time with the people helping you.

Don’t be afraid to cheat with these S’more cookie bombs!

While I shared my delicious and (previously) secret family recipe for sugar cookies with you, there is no shame in using premade cookie dough for these. Especially if you’re going to try cooking these at a campout, the results will be just as yummy because the fillings are the real stars of the show here.

And if you’re baking with kids, they don’t always have the patience for the extra steps involved in making and chilling the dough. They just want to get to the fun part of stuffing and eating the s’more bombs. So I give you full permission to make things easier on yourself. Like I said, just enjoy them, it’s all about having fun!

Different baking methods

In the recipe, I mentioned three different ways to cook these yummy treats. The first is to use a campfire. Kids always love throwing things in the fire and eating them later, it’s a consistent hit at every Boy Scout and family campout I’ve ever been on. Even a plain potato becomes better when it’s been cooked over the coals of a campfire. This way is a little harder to time and may need to be eaten out of the foil with a fork, but it’s always a hit.

The second method is the one I used when taking pictures for this recipe, the grill. I like the grill because it’s almost like an oven but it doesn’t heat up my house, making it a great choice for summertime baking. Just make sure your grill has a thermometer so you can check the temp and lower those flames once the cookies are in.

Also, don’t skip the overturned pan. It helps to distance the pan from the flames a little, allowing the cookies to bake without burning. This method will give a great, flame-grilled taste without the difficulty of baking over a fire.

The third method is the tried and true oven. If you aren’t feeling adventurous enough to use a fire or a grill, there’s nothing wrong with using an oven. It’s the most controlled of the three methods and will give you the most consistent and even cookies. Just make sure to preheat.

Different equipment you can use for this s’more cookie recipe

I also mentioned using a muffin tin to bake these s’more cookie bombs. The cookies tend to spread a lot thanks to all their size. Freezing the dough helps to cut down on the spread (don’t skip that step!) but it can still be considerable. Baking the cookies in the muffin tins helps to control that spread. You’ll end up with little balls that will really remind you of a bomb when you bite in and have the hidden treasures explode in your mouth!

However you choose to cook them, just make sure you use your parchment paper! Never, ever skip parchment paper. I know I tell you this for pretty much every recipe but it’s so important. I remember my life before I learned of the wonders of parchment paper and it wasn’t pretty. Obviously, if you choose to use the muffin tins use the little muffin cups and you’ll be golden.

The most important part

It’s true that Will and Nico spend some time dreaming of s’mores in the Underworld and it helps them push through and finish their quest. But honestly, it isn’t the s’mores that save them, it’s the memories attached to the s’mores. After all, s’mores are so much more than just chocolate and marshmallows smushed between graham crackers. It’s about the people we make them with and the fun we have while we eat them. 

Every time we make s’mores my kids get to hear about the marshmallow-stealing raccoon that swiped the bag right off the table while my friend was standing there, then had a party with his buddy eating the whole bag about 30 feet from the campfire. My kids weren’t even thoughts yet when this happened but they know the story and laugh like they were there every time. It’s connections like these are what s’mores represent to Nico and Will in The Sun and The Star and it’s these connections that make them so important. So make some s’more bombs and even if they turn out flat and you burn them all it’ll be a great story to tell (and they’ll still taste good, I promise).
