What Ingredients You Will Need

This peanut butter smores cookie cup recipe is all about big flavor from simple, everyday ingredients. You won’t need to hunt down anything fancy—just a handful of classics that work together like magic.

• Creamy Peanut Butter (1 cup / 250g) – The star of the show! I usually go with Jif or Skippy for a smooth, classic flavor. Chunky works if you want extra texture, but creamy is my go-to for cookie cups.
• Granulated Sugar (1 cup / 200g) – Sweetens the cookie base and helps create that chewy texture. You can swap in half brown sugar for a slightly deeper flavor (I do this sometimes when I want a caramel note).
• Large Egg (1, room temperature) – Binds everything together. If you forget to take it out early, just soak it in warm water for a few minutes (learned that one the hard way).
• Miniature Chocolate Bars (about 12, like Hershey’s Minis / 120g) – You need one for each cookie cup. I’ve tried dark, milk, and even cookies & cream—each adds its own twist. Break larger bars into pieces if needed.
• Large Marshmallows (12) – Cut in half for a perfect fit. Mini marshmallows work in a pinch, just pile them up until the cup is full.
• Fine Sea Salt (A pinch, optional) – Totally optional, but that tiny sprinkle on top brings out the peanut butter flavor and balances the sweetness. I skip it sometimes if I’m sharing with little kids.

Ingredient Tips: For the peanut butter, avoid natural or “just peanuts” types—they’re too oily and can make the cookie cups fall apart. Regular creamy peanut butter holds everything together best. If you need these gluten-free, double-check your chocolate bars and marshmallows (most are, but always check labels). For a dairy-free version, use dairy-free chocolate and vegan marshmallows.

Substitutions are totally welcome here: swap in almond butter for a nutty twist, or stuff with caramel-filled chocolate for a gooier center. You can even toss in a few mini chocolate chips if you want extra chocolate in each bite. I’ve experimented with all sorts of combos, and honestly, this recipe is super forgiving!

Equipment Needed

• Mini Muffin Pan (24-cup or two 12-cup pans) – Nonstick works wonders, but you can also use a regular muffin tin for larger cups (adjust baking time as needed).
• Mixing Bowl – Medium size is perfect for stirring everything together by hand. No need for a stand mixer here.
• Small Cookie Scoop or Spoon – Helps portion out the dough evenly. I’ve used a tablespoon in a pinch—no fancy tools required.
• Rubber Spatula – Great for scraping every bit of dough from the bowl (don’t leave any behind—trust me!).
• Cooling Rack – Speeds up cooling and keeps the bottoms from getting soggy. If you don’t have one, just slide the cookie cups (in the pan) onto a folded kitchen towel.
• Butter Knife – For loosening the cookie cups from the pan if they stick a little. Metal or plastic both work fine.

I’ve made these peanut butter smores cookie cups with both cheap and pricier muffin pans—honestly, as long as you grease the pan well, you’ll be fine. If you don’t have a mini muffin pan, make six jumbo cookie cups in a regular pan (bake a few minutes longer). For easy cleanup, line the pan with mini parchment circles or use a nonstick spray.

How to Make Peanut Butter Smores Cookie Cups

1. Prep Your Pan: Preheat your oven to 350°F (175°C). Grease a 24-cup mini muffin tin with nonstick spray or a little softened butter. If you only have a 12-cup pan, just bake in batches.
2. Make the Dough: In a medium mixing bowl, combine 1 cup (250g) creamy peanut butter and 1 cup (200g) granulated sugar. Stir well until smooth and glossy—about 1 minute. Add 1 large egg and mix until fully incorporated. The dough will be thick and a little sticky; that’s exactly what you want!
3. Portion and Shape: Use a small cookie scoop or tablespoon to drop about 1 tablespoon (20g) of dough into each muffin cup. Gently press each mound down to form a shallow well in the center—think mini “nests” for the chocolate and marshmallow.
4. Bake the Cookie Cups: Bake in the preheated oven for 10-12 minutes, until the edges look set and just golden. Don’t overbake! The centers will look a little soft, but they’ll firm up as they cool.
5. Add the Chocolate: Immediately after removing from the oven, gently press a miniature chocolate bar piece into the center of each cookie cup. The heat will start to melt the chocolate—yum!
6. Top with Marshmallow: Place half a large marshmallow, cut side down, on top of each chocolate bar. If you’re using mini marshmallows, pile 3-4 on top to cover the chocolate.
7. Broil for Toasty Tops (Optional but Awesome): Turn on your oven’s broiler and pop the muffin pan back in for 1-2 minutes, just until the marshmallows are golden and puffed. Watch closely—marshmallows can go from perfect to scorched in a flash! If you don’t have a broiler, use a kitchen torch or skip this step for a classic gooey finish.
8. Cool and Remove: Let the cookie cups cool in the pan for at least 10 minutes (they’ll be very soft at first). Run a butter knife around the edges to loosen, then gently pop them out onto a cooling rack.
9. Finish and Serve: Sprinkle a pinch of sea salt on top if you like. Serve warm for ultra-melty centers, or let them cool completely for a firmer, chewy treat.

Troubleshooting: If the cookie cups stick a bit, don’t panic—just run a knife around the edges and nudge them out gently. If your marshmallows aren’t browning, try moving the pan closer to the broiler. For best results, don’t overbake—the centers should look slightly underdone when you pull them out.

Cooking Tips & Techniques

• Don’t Overmix: Stir the dough until just combined. Overmixing can make the cookie cups tough instead of tender.
• Use a Cookie Scoop: This keeps the size even, so all your peanut butter smores cookie cups bake at the same rate.
• Watch the Broiler: Marshmallows brown fast (ask me how many I’ve burned…). Never leave them unattended while toasting!
• Let Them Cool: The cookie cups will be fragile straight from the oven. Letting them cool makes removing them way easier (and less messy).
• Customize the Chocolate: Milk, dark, or even caramel-filled bars all work. I love using mini peanut butter cups for a double PB twist.

If you’re baking with kids, let them press the chocolate and marshmallows into the cups—it’s the fun part! And if you run into sticky dough, just wet your fingers a bit before pressing it into the muffin tin. For extra neat edges, wipe the muffin pan’s rim before broiling the marshmallows (I’ve learned this the hard way—sticky marshmallow is no joke to clean).

For a crisper base, try baking an extra minute, but be careful not to overdo it. And if your cookie cups collapse a little after cooling, that’s totally normal—just more room for gooey filling!

Variations & Adaptations

• Gluten-Free Option: This recipe is naturally gluten-free if you use gluten-free chocolate and marshmallows. Double-check your labels just to be safe.
• Nut-Free Swap: Use sunflower seed butter instead of peanut butter for a school-safe, allergy-friendly treat. The flavor’s a little earthier, but still delicious.
• Chocolate Lover’s Version: Use dark chocolate squares and add a sprinkle of mini chocolate chips to the dough before baking. I’ve even tried Nutella instead of chocolate bars—super rich and decadent.
• Seasonal Twist: For a fall vibe, sprinkle a little cinnamon into the dough or top with a pumpkin-flavored marshmallow. In the summer, add a thin slice of banana under the chocolate for a PB-banana s’mores cup. It’s wild.
• Vegan Adaptation: Swap in plant-based egg replacer, vegan marshmallows, and dairy-free chocolate. The result is just as gooey and satisfying.

One of my favorite spins? I once made these with almond butter and a dark chocolate-coconut bar tucked inside—every bite tasted like a candy bar and a campfire treat rolled into one. Don’t be afraid to switch it up based on what you have or your personal cravings!

Serving & Storage Suggestions

These peanut butter smores cookie cups are best served slightly warm, straight from the oven when the chocolate and marshmallow are at their gooey best. I love piling them on a pretty cake stand with extra marshmallows scattered around for a playful look—perfect for a party or family movie night.

Pair them with a tall glass of milk, hot chocolate, or even coffee for grown-ups. For a full-on dessert spread, serve alongside fresh berries or a scoop of vanilla ice cream (trust me, the combo is outrageous).

To store, let the cookie cups cool completely, then place in an airtight container. They’ll keep at room temperature for up to 3 days, or in the fridge for up to a week. If you want to freeze, wrap each cup in plastic wrap and store in a zip-top bag—just thaw at room temp and reheat in the microwave for 10-15 seconds for that melty marshmallow magic.

Over time, the flavors meld and get even more craveable. The cookie base softens a bit, and the marshmallow stays chewy. If you like a slightly firmer cookie cup, just let them cool uncovered for an hour after baking.

Nutritional Information & Benefits
