Peanut Butter No-Bake Marshmallow Cheesecake Bars | The Hopeless Housewife

I have a real problem. It’s serious. I LOVE food that reminds me of being a kid…a little TOO much, it’s almost to the point of being…well, childish. But how can anyone resist anything that has marshmallow in the title? The temptation is just a little too much for me. I start thinking about toasting marshmallows over an open fire, my fingers coated with sticky marshmallow goo that seemed to always get in my hair, all over my clothes and everything I stood near. I think I’d rather have a s’more than almost any other dessert on the planet. That combo is golden. Now throw in some peanut butter and you have this cute little dessert. There is no gooey chocolate and graham crackers- instead there is a chocolate crust with a peanut butter center and a marshmallow cheesecake to top it all off, just an incredible combination. The cheesecake stiffens quite well for a no-bake cheesecake because of the gelatin. Whenever I make these Peanut Butter No-Bake Marshmallow Cheesecake Bars, they quickly disappear, they are delicious! And a trip down memory lane.

Peanut Butter No-Bake Marshmallow Cheesecake Bars


For the chocolate crust:

  • 20 oreos, with centers scraped out.
  • ¼ cup butter, melted

For the Peanut Butter Mixture:

  • 1 ½ cup peanut butter
  • 1 ½ cup powdered sugar

For the cheesecake:

  • ¾ tbsp gelatin
  • ¼ cup water
  • 10 ounces of marshmallow fluff (about 1 ½ jars), or a 10-ounce bag of marshmallows, melted
  • 2 8oz blocks cream cheese, softened
  • ½ tsp vanilla
  • ¾ cup cream


  1. Line an 8x 8 baking dish with parchment paper. Mix the crushed oreos and melted butter together in the bottom of the pan and press so that it comes together as a nice crust.
  2. Make the peanut butter mixture. In a medium bowl, mix the peanut butter and powdered sugar together until smooth with an electric beater. Smooth the peanut butter mixture on top of the prepared crust.
  3. Make the s’mores cheesecake. Add gelatin to the water and let sit until the gelatin starts to swell, about 3-4 minutes (do NOT let sit too long, it will become lumpy). In a medium sized bowl, combine the cream cheese and marshmallow fluff. Beat until combined. In a separate bowl, beat the heavy cream until stiff peaks form. Add vanilla. Fold gelatin and marshmallow mixture into the whipped cream and stir well to combine. Refrigerate for 3 hours or until firm, then serve.

    Hey so I decided to give your recipe a try tonight but hopefully you can give me an answer by tonight if this will work- will it still turn into bars if I used the metal spatula cake pans instead of the glass pans?

  • jessics says:

    What kind of gelatin?

  • sybil says:

    Thank you for this decadent recipe – childhood memories indeed! I have found mixing melted gelatine with the marshmallow fluff before the cream cheese to work better. There is no mention of what to do with the vanilla in the recipe so I beat it into the cream. This is going into my favorites file!

  • Colleen says:

    For the PB layer, could I use the whipped version with the powdered sugar?

  • Megly says:

    I was going to make these bars and share them with a vegetarian friend. Does the gelatin essentially give the marshmallow layer lift and stability? Did you ever try this recipe without and how was it? Thank you 🙂

  • Oh my gosh!! These look AMAZING!!

    Looks great, but I have to know. What do you do with the filling you scrape off of the oreos? Tell the truth, you didn’t lick it off did you? lol

  • These look AMAZING! I’ve never seen anything like them. I definitely want to try this recipe asap, and I think my friends will be very impressed!

  • Tabi says:

  • Laura says:

  • Susan says:

  • Kyra says:

    Can this be refrigerated over night? I’m making these for a get together and won’t have enough time the morning of to let it set for 3 hours.
