Chocolate Peanut Butter Cereal Bars Recipe

Pinterest LinkedIn Tumblr

Chocolate and peanut butter just go together.  Like Romeo & Juliet, thunder & lightening or mac & cheese.  I love Rice Krispies Treats, but wanted something a little different.  I wanted the marshmallowy gooeyness, and the crunch of the cereal.  But I needed to somehow mesh peanut butter and chocolate into a Rice Krispies Treat.  Once I started, I kept getting more and more excited with this creation!  It’s super rich, super dense and super delicious!

What you need:

  • 10 ounces of marshmallows (1 bag mini marshmallows or about 40 large)
  • 6 tablespoons butter
  • 1/2 cup peanut butter
  • 3 cups Reese’s Puffs Cereal
  • 3 cups Cocoa Puffs Cereal


  • 1 bag peanut butter chips (I use Reese’s!)
  • 1/2 cup heavy cream
  • 1/3 cup mini semisweet chocolate chips (you could also use mini marshmallows)

Make them:

Spray a large baking pan (7×11 or larger) with cooking spray.

Take 3 cups of the Cocoa Puffs and put them in a large Ziploc bag.  Smash it up with a rolling pin, heavy pan or your shoe 😉 until you have crumbs.  It doesn’t have to be a fine dust – it’s ok to have larger pieces in there, too.  Just mash it up. Put it in a large bowl, along with 3 cups of the Reese’s Puffs cereal. Mix those together, then set aside.

Using a large saucepan, melt the butter and marshmallows over medium heat.  Stir occassionally.  Once it’s smooth, remove it from the heat. Add the peanut butter and stir until it’s well combined.

Here’s where you need to work quickly.  This stuff hardens really fast, so you’ll need to mix it with some pep in your step.  Pour the marshmallow mix into the cereal bowl.  Stir it up and coat all of the cereal, making sure you’re mixing it well.

Press the mixture into the pan.  You may need to use sprayed or buttered fingers or you can use wax paper to help you pat it down, without sticking to your hands.

Pour the topping over the entire pan, and spread it out, making sure it fully covers the cereal.  I tapped it a few times on the counter to get it to get more incorporated and bleed through a little bit into the bars.  Let it cool completely, then cut them into bars and enjoy!
