Let’s talk about the perfect marriage of chocolate and peanut butter. Seriously I can’t think of any food combination that satisfies any food craving more than this.   I don’t need much, just give me a jar of peanut butter, a spoon and some chocolate chips. 

Come on. Don’t look at me like that. You know you do it to and you know it’s the best feeling in the world.  So despite my love for it, I had the most difficult time coming up with a recipe.  Part of me wanted to recreate this tunnel of peanut butter dessert that I had while in Bermuda last summer.  I had a photo of it but no idea how it was made.  The dessert was a rich brownie topped with creamy peanut butter and some sort of chocolate/candy shell.  It was a marvel and delicious.

Part of me thought I could take the easy route and just make a chocolate and peanut butter macaron but then this idea popped into my head.  Why not make a giant, grown up peanut butter cup? I consider this dessert restaurant worthy and it’s seriously impressive but deceptively easy. 

There is a little bit of equipment required when making this recipe – just some silicone muffin/cupcake liners and a digital scale (like the one from OXO) is helpful.   I haven’t tried making the shells in regular cupcake liners but with the silicone ones, it’s easy to just peel it right off the chocolate after it sets.  As you can see, a little bit still broke from the edges but just call the look rustic.

Dark Chocolate Peanut Butter Mousse Cups
Save Recipe


  • 8oz dark chocolate, chopped
  • 1 cup no-stir natural style creamy peanut butter
  • 2oz cream cheese, room temperature
  • 1/4 cup powdered sugar
  • 1/4 teaspoon salt
  • 1 1/4 cup heavy cream, divided


  1. In a double boiler or water bath melt the chocolate until about it is 3/4 of the way melted. Remove from the heat and stir until completely melted.
  2. Place 1 silicone muffin cup on a digital scale and tare to zero. Pour in 1 ounce of melted chocolate and swirl the chocolate around the sides and bottom of the cup. You want the chocolate to go about halfway up the sides, swirling 4-5 times.
  3. Repeat 3 more times.
  4. Place the chocolate coated cups on a baking tray and into the freezer for 15-20 minutes to set.
  5. Save the remaining chocolate for the chocolate sauce.
  6. In the bowl of your stand mixer fitted with the whip, whisk 1 cup of heavy cream until stiff peaks form.
  7. In a medium bowl, combine the peanut butter, cream cheese, powdered sugar and salt. Mix in about 1/4 of the whipped cream to get a creamy consistency.
  8. Place 1/3 o the remaining whipped cream in the bowl and with a rubber spatula carefully fold in the whipped cream, careful not to deflate. Rotate the bowl as you fold in the whipped cream. Add the next 1/3 and fold and then finish with the rest.
  9. Place the peanut butter mousse in a pipping bag fitted with a tip of your choice (I used a 1M tip).
  10. Remove the chocolate cups from the freezer and very carefully peel back the silicone cups.
  11. Pipe in a generous amount of mousse in each cup. There may be some mousse leftover and you can store that in the refrigerator for another use.
  12. Lastly, place the remaining chocolate back on the double boiler or water bath and add the remaining heavy cream. Warm until the sauce is thin and pourable.
  13. Pour the sauce over the cups just before serving.

    Chocolate/peanut butter is my most favorite combo ever. Blogging/reading blogs when you gave up sweets for Lent is tough! 🙂 Can’t wait until Easter!

    These look ah-mazing! The first thing that popped in my head was to do a PB filling in a chocolate cup, but then I changed my mind – these are even better than I imagined them – the sauce over-top is killer!

    I actually stopped scrolling down just so I could stare at your photo of these heavenly cups for a while. Pinned and I will be dreaming about these for a long, long time.

    It’s so crazy that today is a self-declared chocolate peanut butter day. I just threw a new recipe post up that coincides miraculously! I’m so excited, wish I hadn’t noticed this right at bed time, now I’ll be up all night…

      Yes I can! I’ll shoot you an email when you’re back from vacation on how I do it (and it’s really easy too)!

  14. Nancy @ gottagetbaked

    Girl, you so fancy! These are beautiful, Susan. Those little chocolate cups are perfect and I’m jealous of your piping skills with that luscious peanut butter filling. As for the pouring of the chocolate sauce over top…oh baby. I used this phrase in my comment on Courtney’s cake post and I’ll say it here: it’s like the best food porn evah! I hope you’re having in incredible time in Italy (judging by all the photos of the amazing food and sites, I’d say you are! You deserve it, lady!).

    1. Susan Palmer

      Don’t be jeals of the piping skills. It’s pretty easy and all thanks to the right tip. 🙂

  15. Isabelle @ Crumb

    Love these! Though I’d probably end up piping piping half of that delicious peanut butter filling straight into my mouth instead of all pretty-like into the cups, because I’m totally classy like that. 😉

    My favorite homemade chocolate peanut butter treat is my Oatmeal Chocolate chip Peanut Butter Cookies. Mmmmm they are so good. My favorite store bought chocolate peanut butter treat is of course Reese’s Cups in the holiday shapes. You get more peanut butter in those. 🙂

    I love these more than making traditional peanut butter cups because these are much bigger. Bigger = more peanut butter and chocolate.

    These look so fantastic! I’m making them tonight and I was just wondering if you used mini-muffin cups or regular sized muffin cups.

    1. Susan Palmer

      Thank you Christina! I actually used jumbo silicone muffin cups but regular sized cups would work as well. Enjoy them tonight!

    Holy cow, they look fantastic. Have to get together with my sister and make them for the family. I’m sure they will love them.

    You did a wonderful job. I made these in 2004 and then lost the recipe. I was so excited to find it again. I sent them to my husbands co-workers and clients and they loved them. Thank you for posting this recipe. Everyone should make these at least once. You will be hooked and people will be requested often. Thanks again.

    A fan of your creativity and ideas,
