Why Make This Ghost Peep S’mores Bars Recipe
You should make this recipe because it is incredibly festive without requiring advanced baking skills. Using Ghost Peeps is a simple shortcut that adds a lot of personality to your dessert. It turns a standard tray of bars into a spooky scene that looks much more impressive than the effort it takes to put together.
Another reason to love these bars is their portability. While traditional s’mores are messy and need to be eaten immediately, these bars hold their shape well once cooled. This makes them perfect for school potlucks, office parties, or gifting to neighbors in “You’ve Been Boo’d” baskets.
How to Make Ghost Peep S’mores Bars Recipe
Creating these spooky treats is a simple process that involves layering flavors to build the ultimate dessert bar. Just follow these easy steps to get a perfect result every time.
Ingredients
- 1 1/2 cups graham cracker crumbs
- 1/2 cup unsalted butter, melted
- 1/4 cup granulated sugar
- 1/4 teaspoon salt
- 2 cups milk chocolate chips (or 4 standard-sized Hershey bars)
- 1 package (9-12 count) Ghost Peeps marshmallows
- Optional: 1/4 cup mini semi-sweet chocolate chips for extra decoration
Directions
Step 1: Preparation
Preheat your oven to 350°F (175°C). Line an 8×8 inch square baking pan with parchment paper, leaving a little overhang on the sides. This will make it much easier to lift the bars out of the pan once they are finished.
Step 2: Create the Graham Cracker Base
In a medium-sized mixing bowl, combine the graham cracker crumbs, melted butter, sugar, and salt. Stir the ingredients together until the mixture looks like wet sand. Press the mixture firmly into the bottom of your prepared baking pan using the back of a spoon or a flat measuring cup.
Step 3: Pre-Bake the Crust
Place the crust in the oven and bake for about 8 to 10 minutes, or until it is lightly golden brown and set. This step ensures the crust stays crunchy and doesn’t get soggy from the toppings.
Step 4: Add the Chocolate Layer
Remove the pan from the oven and immediately sprinkle the milk chocolate chips (or lay the chocolate bars) evenly over the hot crust. Let it sit for 2-3 minutes until the chocolate begins to soften. You can gently spread the chocolate with a spatula if you want a completely smooth layer.
Step 5: Arrange the Ghost Peeps
Place the Ghost Peeps on top of the chocolate layer in rows. You can fit them snugly so every bar gets a ghost, or space them out depending on how many bars you plan to cut. If you want extra chocolate, sprinkle a few mini chocolate chips in the gaps between the ghosts.
Step 6: Final Bake and Toast
Return the pan to the oven for another 5 to 7 minutes. Watch closely! You want the marshmallows to puff up and become slightly golden, but you don’t want the ghosts to melt away completely. For a more “toasted campfire” look, you can turn on the broiler for the last 30 seconds, but stay right there to prevent burning.
Step 7: Cooling and Slicing
Remove the pan from the oven and let the bars cool completely in the pan on a wire rack. Once cooled, use the parchment paper overhang to lift the entire block out. Use a sharp, greased knife to cut the bars into squares.
How to Serve Ghost Peep S’mores Bars Recipe
These bars are best served at room temperature so the chocolate is set but the marshmallow remains soft. If you prefer a gooey experience, you can serve them while they are still slightly warm. For a truly decadent dessert, serve a warm bar with a scoop of vanilla bean ice cream on the side.
How to Store Ghost Peep S’mores Bars Recipe
Store any leftover bars in an airtight container at room temperature for up to 3 days. If you need to stack them, place a sheet of wax paper or parchment paper between the layers so the marshmallow ghosts don’t stick to the bottoms of the bars above them. It is not recommended to refrigerate these, as the crust can become too hard.
Expert Tips for Perfect Ghost Peep S’mores Bars Recipe
To get the cleanest cuts, lightly coat your knife with non-stick cooking spray before slicing through the marshmallow layer. Another tip is to ensure your graham cracker crust is pressed down very firmly; a loose crust will crumble when you try to eat the bars. Finally, if you want the faces of the ghosts to stay sharp, avoid over-baking them, as the features can blur if the marshmallow gets too hot.

Delicious Variations
You can easily customize these bars to suit your taste. Try using dark chocolate chips for a less sweet, more intense flavor. You can also add a layer of peanut butter chips under the marshmallows for a “fluffernutter” twist. If you want more texture, sprinkle crushed pretzels over the chocolate layer before adding the Peeps for a salty-sweet combination.
Frequently Asked Questions
Q: Can I use regular marshmallows if I can’t find Ghost Peeps?
Yes, you can use regular large marshmallows. After baking, you can use a food-safe black marker or melted dark chocolate to draw your own ghost faces on them.
Q: Do I have to use graham cracker crumbs?
No, you can use crushed digestive biscuits or even Biscoff cookies for a different spice profile in the crust.
Q: How do I prevent the marshmallows from sticking to the knife?
Wiping the knife with a damp cloth or applying a tiny bit of butter or oil to the blade between each cut helps significantly.
Q: Can I freeze these s’mores bars?
It is not recommended to freeze them. The texture of the marshmallow Peeps changes when frozen and thawed, often becoming rubbery or sticky.
Q: Can I make this in a larger pan?
Yes, you can double the ingredients and use a 9×13 inch pan. Just keep an eye on the bake times, as they may vary slightly.
Conclusion
Ghost Peep S’mores Bars are the ultimate easy Halloween treat. They combine the classic flavors we all love with a whimsical holiday twist that delights people of all ages. Simple to make and even easier to share, these bars are sure to become a seasonal favorite in your household. Happy baking and Happy Halloween!
