Peanut Butter Rice Krispie Treats with Reese’s Pieces

Last night, Brian called me at 8:30 as I was driving home from a long day of trying on jeans, buying lipgloss, and eating crab cakes – can you tell my summer is still lacking purpose?

He wanted to inform me that he was “thinking” about inviting a friend over to watch the Miami Heat game. Which translates to, “I’ve already asked someone to come over, so it’s cool, right?”

He then hinted that he was hungry, so I offered to stop and buy brats, chips and beer. And being the ever so amazing woman that I am, I also decided to whip up a quick dessert for them to nosh on during their breaks from yelling at the refs and that one guy that used to play for the Cavs.

After a quick scan of my pantry, I quickly decided that Reese’s Pieces Rice Krispie Treats were going to happen and happen they did. These certainly aren’t anything fancy, but sometimes it’s the simple recipes that bring the biggest smiles!

Creamy peanut butter, marshmallows, Rice Krispies, and Reese’s Pieces – what more could hungry, basketball watching men want?


Reese's Pieces Rice Krispie Treats

Yield: 24 servings

Prep Time: 10 minutes


3 tablespoons unsalted butter
5 3/4 cups miniature marshmallows; divided use
2/3 cup creamy peanut butter
1/2 teaspoon pure vanilla extract
6 cups crisped rice cereal (Kellogg's Rice Krispies)
1 cup Reese's Pieces


1. Line a 9 x 13 x 2 inch baking pan with foil and spray with nonstick cooking spray.

2. In large saucepan melt butter over low heat. Add in 5 cups of marshmallows and stir until completely melted. Add in the peanut butter and continue stirring until the mixture is smooth. Remove from heat and stir in vanilla extract.

4. Using buttered spatula, press the mixture into the prepared pan. Cool. Cut into 2-inch squares.


- Peanut Butter Rice Krispie Treats are best if served the same day they are made.

    Reese’s Pieces. TOTAL throwback to when I was a kid. I used to always get them at the movies. Of course, now it’s once in a blue moon!


  20. rice krispie treats are so simple yet remain one of my favorite desserts, especially with add-ins like Reese’s pieces :)

  24. Debra Kapellakis — June 12, 2012 at 12:36 pm

  25. PB Rice Krispies w/ Reese’s Pieces… so simple and yet SO delicious! I am loving today’s recipe, Jamie! And did you know today is National PB Cookie Day? I think I should make these just to celebrate. :)


  26. Cookbook Queen — June 12, 2012 at 3:48 pm

    LOVE these!! I can’t believe I’ve never thought of it.

    And yes, you are the best. Brian is so lucky!!! Because honestly, I would have hid in the bedroom with some Peanut M &Ms and Pretty Little Liars on DVD while they scrounged.


  27. Michelle B. — June 25, 2012 at 6:52 pm

    These looked so good but I just tried to make them & they definitely didn’t turn out. I rechecked the ingredient list & I followed it. Mine were really dry. Couldn’t barely stir it. The Reese’s Pieces & extra marshmallows couldn’t be mixed in, they all fell to the bottom as I was trying to stir. It came out as one big glob. Not that I didn’t snack off the glob, but I won’t be bringing these to my BBQ as planned. Anyone else have problems? What did I do wrong?

    My mom used to make something a little different from this…regular RK treats with peanut butter icing…royal icing with peanut butter in it was my FAV…now this recipe with that frosting would be AMAZING!!!!!


  29. Sabrina — March 20, 2013 at 3:30 pm

    I had to double the amount of marshmallows to make the consistency turn out right. The 5 3/4 cups was way too “dry” for them to stir together with the 6 cups of Rice Krispies. I kept the peanut butter and the Reese’s amounts the same though, and they turned out pretty good!


  30. Jenny — September 6, 2013 at 7:53 pm

    Made these tonight, exactly as the recipe stated. AMAZING! Don’t want to share with the kids! Thanks for the idea!
