Ingredients

• Peanut Butter Cups: choose regular size for just the right ratio of chocolate to peanut butter. Look for ones that feel firm in the package to keep the chunks distinct in the mix
• Salted Butter: adds a rich base and balances the sweetness. Fresh butter has the best flavor
• Smooth Peanut Butter: creamy texture holds the bar together. Go for shelf stable brands for easy mixing
• Mini Marshmallows: melt fast and bring that classic gooey bar texture
• Captain Crunch Cereal: the star ingredient for crunch and a hint of corn sweetness. Pick a box with the brightest yellow color for maximum freshness
• Mini Reese’s Pieces: sprinkle on while the bars are warm so they stick but do not melt

Instructions

Chop the Candy:

Cut the peanut butter cups into small even pieces so they melt smoothly into the base and each bar gets bites of candy

Melt the Butter and Peanut Butter:

In a large saucepan add the butter and the smooth peanut butter. Warm over medium low heat stirring often until fully melted and glossy with no streaks

Melt in the Marshmallows:

Toss all the mini marshmallows into the pan. Stir gently but steadily letting them melt down until the mix is very smooth and completely combined

Blend with Cereal:

Remove the saucepan from the heat. Add all of the Captain Crunch cereal at once. Stir slowly folding the mix so every piece is coated and nothing is dry

Mix in the Peanut Butter Cups:

Drop in your chopped peanut butter cups and fold gently. You want them to melt just a bit but leave chunks throughout

Spread into a Pan:

Pour the warm mix into a greased nine by thirteen inch pan. Use a spatula or buttered fingers to press evenly into the corners with a little pressure to make it compact

Make the Peanut Butter Topping:

Combine butter and peanut butter in a microwave safe bowl and heat until both melt. Mix until totally smooth and fluid

Decorate the Bars:

Drizzle about half of the topping over the pressed bars making sure every spot gets covered. Quickly sprinkle mini Reese’s Pieces on top letting them stick to the warm topping. Finish drizzling with the rest for beautiful ribbons

Chill and Slice:

Pop the whole pan into the fridge for one hour. Chill until firm then use a sharp knife to slice into bars or squares

My favorite part is sneaking a bite of the crispy peanut butter bar right as it comes out of the fridge while the topping is still just a touch soft. Sometimes my family fights over who gets the corner pieces with extra chocolate chunks because those are always the best.

Storage and Leftover Tips

Store any leftovers tightly covered in the fridge where they will stay fresh for up to five days. I like layering parchment between the bars to keep them from sticking together. If you need them for later just let them warm up for ten minutes at room temperature before eating for perfect chewy texture.

Easy Ingredient Swaps

If you only have chunky peanut butter it works for a bit of extra bite. Swap marshmallows for vegan versions if needed or use chocolate crisp cereal to change the flavor. In a pinch you can scatter chocolate chips on the topping instead of Reese’s Pieces though nothing beats the color of the original.

Perfect Ways to Serve This

Slice into bite size squares for a fun party platter or wrap individual bars for lunchboxes. Try topping them with mini pretzels or a sprinkle of sea salt before the topping sets for added crunch. These are also amazing crumbled over vanilla ice cream for a super easy dessert.

With a handful of ingredients and almost no prep you can bring a nostalgic favorite to your next celebration. Make these even once and you will always have a hit recipe ready for any happy craving.

Recipe Q&A

→ Can I use a different cereal for this dessert?

Yes, similar crispy cereals like Rice Krispies or Cornflakes can be used for a different texture and flavor.

→ Should I use salted or unsalted butter?

Salted butter is recommended for enhanced flavor, but unsalted butter works if you prefer a milder taste.

→ How do I prevent the bars from sticking to the pan?

Generously grease the pan or line it with parchment paper to make slicing and serving easier.

→ How long do the finished bars last?

Stored in an airtight container, the bars stay fresh for up to 5 days at room temperature or refrigerated.

→ Is it necessary to chill the bars before serving?

Chilling helps the bars set and makes them easier to slice. Allow at least an hour in the refrigerator.
