Peanut Butter Cup S’mores

Oct 29, 2025 • Tom Jackson

These Peanut Butter Cup S’mores are porch-party perfect—fast, fun, and wildly satisfying. We toast marshmallows over glowing charcoal embers for that ideal contrast: crisp, caramelized exterior and a gooey, molten center. Instead of grahams, we sandwich the marshmallow and a peanut butter cup between chocolate chip cookies (or chocolate wafers) so the chocolate softens and the peanut butter oozes with every bite. The brasero setup on a live fire makes it easy to manage gentle, even heat, but a simple fire pit works just as well. Kids can join the toasting with long skewers and a designated “ember zone,” turning dessert into an interactive moment. From lighting the coals to that first sticky, chocolate-smudged grin, you’re only minutes away from a nostalgia-rich treat with a playful twist—perfect for Halloween night or any backyard hangout.

Directions

Build a small live fire. Light lump charcoal and dump into the brasero. Feed a few small wood splits to create a steady bed of glowing coals; you want heat without big flare-ups.
Skewer the marshmallow and hold it over the coals, rotating for even color. Aim for a toasted, golden exterior with a soft, melting center. (If you like it charred, let it kiss the flame briefly, then blow it out.)
While the marshmallow toasts, set one cookie flat-side up. Place the peanut butter cup on top so it starts to soften from ambient heat near the fire.
When the marshmallow is crisped outside and molten inside, slide it off the skewer onto the peanut butter cup. Cap with the second cookie and press gently until the chocolate starts to melt. Wait 10–15 seconds for the molten sugar to cool slightly—then enjoy.

Recipe Note

Peanut Butter Cup S’mores FAQ

Can I make these without a brasero?
Yes—any safe fire pit or charcoal grill works. Aim for a steady bed of glowing embers for even toasting.
What cookies work best?
Chocolate chip cookies give classic crunch; chocolate wafer cookies intensify the cocoa. Oreo-style sandwiches are a fun twist.

How do I toast marshmallows evenly?
Hold the skewer just over embers and rotate constantly. Embers brown gently; direct flame chars fast and can leave the center cool.

How do I keep kids safe around the fire?
Use long skewers, establish an “ember zone,” supervise closely, and blow out any flaming marshmallows immediately. Let finished s’mores rest 10–15 seconds to avoid burns.

Should I pre-warm the peanut butter cup?
Yes—rest it on the cookie near the fire while you toast the marshmallow so it softens and melts on contact.

Can I prep anything ahead?
Lay out cookies, unwrap peanut butter cups, and set a safe landing board for hot marshmallows. Toast and assemble to order for best texture.
