I wasn’t planning on posting another recipe featuring mini peanut butter cups so soon after the glorious overindulgence known as Gooey Chocolate Peanut Butter Cup Cookies, but the timing just sort of worked out this way.  And also: mini peanut butter cups. And furthermore: fuuuuudge. And in conclusion: YUM.

This is one of my favorite fudge recipes. It’s a “no-beat” fudge, meaning you don’t have to go through the rigmarole of cooking it, cooling it, then beating until your little arm falls off and hoping you get the timing exactly right so that it sets perfectly. Instead, you cook it, stir in some peanut butter, and give yourself giant pats on the back for making such great fudge. The peanut butter adds a nice salty touch, so it’s not too sweet, and unfortunately that means you can eat piece after piece without feeling any pain. If you are a serious peanut butter fan, don’t miss my Chocolate Peanut Butter Cheesecake, Mega Stuffed Peanut Butter Cups and Peanut Butter Cup Popcorn Balls!

Instructions 

  • Line a 9×9 pan with foil and spray the foil with nonstick cooking spray.
  • Place the cubed butter in a medium saucepan over medium heat, and gently warm it up until it is mostly melted. Once it is almost completely liquid, add the evaporated milk, the granulated sugar, and the salt, and stir until the sugar dissolves. Wash down the sides of the pan with a wet pastry brush to prevent sugar crystals from forming. Bring the mixture to a boil, and once boiling, insert a candy thermometer. Continue to cook the candy, stirring occasionally, until it reaches 236° Fahrenheit (113°C) on the thermometer.
  • Once at 236°F, remove the pan from the heat and add the peanut butter, marshmallow cream, and vanilla extract. Stir until the peanut butter and marshmallow cream are incorporated and everything is completely smooth.
  • Pour approximately half of the fudge into the prepared pan and smooth it into an even layer. Working quickly, sprinkle half of the miniature peanut butter cups on top of the fudge in the pan. Pour the remaining fudge into the pan, covering the peanut butter cups, and smooth it into an even layer. Sprinkle the rest of the candies on top of the fudge. Once they come into contact with the hot fudge they will start to melt, so try not to disturb them after you’ve sprinkled them on, otherwise the chocolate will smear.
  • Let the fudge cool and set at room temperature overnight, or in the refrigerator for at least 3 hours. When set, remove the fudge and peel off the foil backing. Use a large sharp knife to cut the fudge into 1-inch pieces to serve. Wrap the fudge well and store it in an airtight container in the refrigerator for up to two weeks. For the best taste and texture, bring it to room temperature before serving.

Recipe Notes

Miniature peanut butter cups can be found at Trader Joe’s or Fresh & Easy grocery stores. They’re also sold by Reese’s and are at many drugstores. If you can’t find them, you can chop up regular peanut butter cups and use those chunks instead. Additionally, you can swap out the mini peanut butter cups for chocolate chips, chopped candy bars, or salted nuts instead.

Measuring Tips

Our recipes are developed using weight measurements, and we highly recommend using a kitchen scale for baking whenever possible. However, if you prefer to use cups, volume measurements are provided as well. PLEASE NOTE: the adage “8 oz = 1 cup” is NOT true when speaking about weight, so don’t be concerned if the measurements don’t fit this formula.

  1. Elizabeth this is seriously gorgeous fudge. I must try this one. And can I just say we don’t have Trader Joe’s here in Canada but I just happened to buy some of their mini peanut butter cups when we were in Philly. So I can attest to how good they are. Like a thousand times better than any other ones I’ve ever had. I used a different brand for mine and now that I’ve had TJ’s I’m spoiled and nothing else tastes as good.

    1. Kim, I couldn’t agree with you more! It’s like the peanut butter inside is extra-salty and smooth or something. It tastes like real peanuts, and it’s FAB. Other brands just aren’t the same. Obviously you need to plan more vacations around TJ’s proximity!

  2. These look amazing!! I love the idea!!

    I wouldnt know where to find the mini peanut butter cups in Spain.. perhaps I could find it here in South Africa while visiting my family..
    You guys have everything over there in the US

    1. Thanks Johlene! Regular peanut butter cups would work too (just chop them up) or hey, chocolate chips or chopped-up candy bars would also be tasty!

  3. One can never have too many recipes for mini peanut butter cups. Especially when one has a tendency to eat the whole bag in one sitting so she’d better have a plan to use them up before that can happen. This fudge – want.

    1. Well, in that hypothetical scenario, one is totally innocent, because no mere mortal can resist mini peanut butter cups. So no worries, the blame falls squarely on the candy!

  4. OMW. Peanut butter cup fudge? That’s just an amazing little treat! Pinning this. 🙂

  5. Oh my goodness, don’t apologize! Reeses make everything better! Especially this fudge!

  6. Oh, Muffin! Sweet thing.

    Speaking of sweet things, YES to this! I’m enjoying all the creations spurned by impulse candy purchases very much.

  7. I tried making fudge one day not too long ago and it was a flop. The kids still ate it but it didn’t stay together and my husband tried throwing it out! I will have to try again and see if it works out for me…love the flavor of this one! 🙂

    1. Boo, bad fudge is the worst! I feel pretty confident in saying this fudge will work for you–the marshmallow cream makes it pretty foolproof and not-fall-apart-able. 🙂 Let me know how it goes if you give it a try!
