These S’mores Peanut Butter Cups are a fun treat that combines chocolate, peanut butter, and marshmallows—all in one bite! It’s like campfire fun, but easier!
How can you resist a tasty combo of gooey marshmallows and creamy peanut butter? They’re perfect for sharing, but I usually keep a stash just for myself. Whoops! 😅
Key Ingredients & Substitutions
Graham Crackers: These provide the classic base for S’mores. If you’re gluten-free, use gluten-free graham crackers or crushed nuts as a crunchy alternative.
Peanut Butter: Creamy peanut butter is perfect for this recipe. If you prefer a different nut butter, almond or cashew butter works well too, though it will slightly change the flavor.
Chocolate Chips: Semi-sweet or milk chocolate adds sweetness. For a darker flavor, try dark chocolate. You can also substitute with dairy-free chocolate for a vegan option!
Mini Marshmallows: These add the gooey texture you expect. You can use large marshmallows cut into smaller pieces or even marshmallow fluff if it’s what you have on hand.
How Do You Make the Perfect Graham Cracker Crust?
The graham cracker crust is a key part of the S’mores experience. It should be firm enough to hold the goodies without crumbling. Here’s how to get it right:
- Make sure to mix the crumbs with sugar and melted butter evenly.
- Press the mixture firmly into the muffin tin for a stable base.
- If you want a crunchier crust, bake it at 350°F for about 5-7 minutes before filling.

How Much Time Will You Need?
This delightful treat takes about 20 minutes of prep time, plus 1 hour to chill in the refrigerator. It’s perfect for making ahead of time for gatherings or sweet cravings at home!
Step-by-Step Instructions:
1. Prepare the Graham Cracker Crust:
In a medium bowl, mix together the graham cracker crumbs, sugar, and melted butter. Stir until everything is combined, and the crumbs feel wet. Press about a tablespoon of this mixture firmly into the bottom of each cup in the mini muffin tin to create your crust. Set aside.
2. Add the Peanut Butter Layer:
In a microwave-safe bowl, warm the creamy peanut butter for about 20-30 seconds until it’s just softened (not hot!). Spread roughly one teaspoon of peanut butter onto each graham cracker crust, making sure it’s even.
3. Make the Chocolate Layer:
In another microwave-safe bowl, combine the chocolate chips and heavy cream. Microwave in 20-second intervals, stirring in between, until the mixture is smooth and glossy. This should only take a couple of minutes!
4. Assemble the Cups:
Pour or spoon the melted chocolate mixture over the peanut butter layer in each cup. Make sure to cover the peanut butter completely.
5. Top with Mini Marshmallows:
Place 2-3 mini marshmallows on top of the chocolate layer in each cup. If you have a kitchen torch, use it to carefully toast the marshmallows until they’re golden brown. If you don’t have a torch, you can place them under the broiler for about 1-2 minutes, but watch closely to avoid burning.
6. Chill and Set:
Refrigerate your S’mores Peanut Butter Cups for at least 1 hour, allowing the chocolate to set properly.
Once they’re set, pop them out of the muffin tin and enjoy these tasty treats! With their mix of crunchy crust, creamy fillings, and gooey toppings, they’re sure to become a favorite! 🍫🔥
Can I Use Other Types of Nut Butters?
Absolutely! You can substitute creamy peanut butter with almond butter, cashew butter, or even sunflower seed butter for a nut-free option. Keep in mind that this will change the flavor slightly, but they all make delicious alternatives!
How Do I Store Leftover S’mores Peanut Butter Cups?
Store any leftovers in an airtight container in the refrigerator for up to one week. They can also be frozen for longer storage—just make sure to wrap them tightly to avoid freezer burn!
What If I Don’t Have Mini Marshmallows?
No problem! You can use regular-sized marshmallows cut into smaller pieces, or even marshmallow fluff as a topping. Just ensure to heat it carefully to achieve that delicious toasted flavor!
Can I Make These Ahead of Time?
Definitely! These S’mores Peanut Butter Cups can be made up to three days in advance. Just keep them stored in the fridge and allow some time to come to room temperature before serving for the best texture.
