S’mores Peanut Butter Cups are a fun and sweet treat that brings the campfire classic to your kitchen. With creamy peanut butter and a crispy graham cracker layer, they’re simply delightful!
Who can resist the combination of chocolate, marshmallow, and peanut butter? I love making these for movie nights! They disappear faster than I can grab one! 🍫
Key Ingredients & Substitutions
Graham Cracker Crumbs: Essential for that classic s’mores taste, graham cracker crumbs form the base. If you don’t have these on hand, try using crushed digestive biscuits or vanilla wafers as a replacement.
Peanut Butter: Creamy peanut butter gives a smooth texture. If you’re looking for a healthier option, almond butter or sunflower seed butter can be a great substitute. They also add a unique flavor!
Chocolate Chips: Semi-sweet chocolate is a go-to for these cups, but you can use dark chocolate or even milk chocolate if you prefer a sweeter taste. For a dairy-free version, choose vegan chocolate chips.
Marshmallows: Mini marshmallows are convenient and cute in these cups. If you only have large marshmallows, just cut them into smaller pieces. You can also skip them for a nut-free version!
How Do I Achieve the Perfect Layered Structure?
Building layers in your peanut butter cups is key to achieving the delicious s’mores effect. Start with the crust by pressing the graham cracker mixture firmly into the muffin tins to create a solid base that holds everything together.
- Mix the crust ingredients thoroughly for an even texture.
- Don’t skip pressing the crust firmly; this ensures it holds up when you bite into it!
- Let each layer set slightly before adding the next. This will help keep your marshmallows from sinking into the peanut butter layer.
- Chill the assembled cups long enough to let the chocolate set properly — patience helps create the best texture!

How to Make S’mores Peanut Butter Cups
Ingredients You’ll Need:
For the Crust:
- 1 1/2 cups graham cracker crumbs (about 10 full sheets)
- 5 tablespoons unsalted butter, melted
- 2 tablespoons granulated sugar
For the Peanut Butter Filling:
- 3/4 cup creamy peanut butter (divided: ½ cup + 1/4 cup)
- 1 tablespoon powdered sugar
- 1/2 teaspoon vanilla extract
For the Chocolate Layer:
- 1 1/2 cups semi-sweet chocolate chips
For the Marshmallow Layer:
- 1 cup mini marshmallows (or large marshmallows cut to size)
- Extra graham cracker crumbs for topping
Time Needed:
This recipe takes about 30 minutes to prepare and requires chilling in the refrigerator for at least 1-2 hours until the chocolate is firm. Quick to make, but a little patience is needed to let these delicious cups set!
Step-by-Step Instructions:
1. Prepare the Crust:
In a medium mixing bowl, combine the graham cracker crumbs, melted butter, and granulated sugar. Stir until everything is evenly mixed and the crumbs are moistened.
2. Form the Base:
Line a standard 12-cup muffin tin with cupcake liners. Take about a tablespoon of the graham cracker mixture and press it firmly into the bottom of each cup to form a solid crust layer. Make sure to pack it well so it holds together.
3. Make the Peanut Butter Filling:
In a small bowl, mix ½ cup of the creamy peanut butter with the powdered sugar and vanilla extract until you achieve a smooth and creamy consistency. This will be your delicious filling!
4. Assemble the Layers:
Spoon about a teaspoon of the peanut butter filling on top of each crust. Spread it gently to cover the crust evenly. Next, add a few mini marshmallows or pieces on top of the peanut butter layer.
5. Melt the Chocolate:
In a microwave-safe bowl, melt the chocolate chips in 30-second intervals. Stir after each interval until the chocolate is fully melted and smooth. Be careful not to overheat!
6. Add the Chocolate:
Pour about 2 tablespoons of melted chocolate over the marshmallow layer in each cup, ensuring they’re fully covered. This locks in all that deliciousness!
7. Top and Chill:
Sprinkle extra graham cracker crumbs on top of the chocolate layer for that classic s’mores touch. Place the muffin tin in the refrigerator for at least 1-2 hours until the chocolate is set and firm.
8. Serve:
Once the chocolate is set, carefully remove the peanut butter cups from the muffin liners. Enjoy your S’mores Peanut Butter Cups chilled or at room temperature. Get ready for the smiles as everyone digs in!
These delightful treats are loaded with layers of flavor and texture, making them the perfect blend of sweet indulgence and nostalgic campfire fun!
Can I Use Different Types of Chocolate?
Absolutely! While semi-sweet chocolate chips are the classic choice, you can experiment with dark chocolate for a richer taste or milk chocolate for a sweeter flavor. Just ensure they melt smoothly!
How Do I Store Leftovers?
Store any leftover S’mores Peanut Butter Cups in an airtight container in the refrigerator for up to a week. They taste great chilled, but you can also let them sit at room temperature for a few minutes before enjoying!
Can I Make These Vegan?
Yes! You can make these vegan by using dairy-free chocolate chips, maple syrup instead of powdered sugar, and natural nut butters free of additives. Just double-check the ingredients to ensure they’re vegan-friendly!
What Other Fillings Can I Use?
If you want to switch things up, try adding chopped nuts, caramel sauce, or different flavored nut butters instead of peanut butter! Just be mindful that it might change the texture a bit.
