This easy Chocolate Peanut Butter Fudge swirl is quite possibly heaven on earth. Think Reese’s Peanut Butter Cup in fudge form. At first glance, I know this looks like a complicated recipe but it is actually SUPER easy. This is a variation of our See’s Fudge Recipe. And much like that classic fudge recipe, this one can be made in less than 20 minutes. It’s a simple, foolproof, no-bake recipe that has a smooth, creamy texture, and a huge peanut butter and chocolate flavor that just melts in your mouth. This 7 ingredient fudge makes wonderful Christmas gifts or just a sweet treat for any occasion.

Ingredients for Chocolate Peanut Butter Fudge

This treat is really easy to make and even more fun to eat! Here’s all you need:

  • 8 ounces of milk chocolate – I use two Hershey bars, broken into pieces.
  • Semi-sweet chocolate chips – one bag, or 12 ounces. Dark chocolate chips should work fine, too. We don’t recommend milk chocolate chips as they may make the fudge too sweet.
  • Peanut butter chips – 2 packages, 10-12 ounces each. I like the Reese’s brand.
  • One stick of butter – divided.
  • Marshmallow fluff (also known as Marshmallow Creme or Marshmallow Cream) – one 7-8 ounce jar, divided
  • Sugar – regular granulated sugar. No substitutions.
  • Evaporated milk – NOT sweetened condensed milk.

Update:

I have updated this recipe due to many comments about the difficulty in finding white chocolate bars. The original recipe called for an eight ounce white chocolate bar, but this is now substituted with an additional package of Reese’s Peanut Butter chips. You can still use the white chocolate bars if you can find them, but I’ve found that doubling up on the peanut butter chips gives this fudge a richer peanut butter flavor (no complaints here)! I have tested this substitute with success, and think you’re going to love it!

That Being Said… No (Additional) Substitutions Please

With this recipe, you really don’t want to substitute anything. Trust me, it is perfect the way it is. Some have tried substituting marshmallows for the marshmallow fluff and have been disappointed. Same with using creamy peanut butter instead of peanut butter chips. It won’t set up the same. If you want it to turn out right, it is worth following the recipe exactly (I know, I am not one to follow recipe instructions EXACTLY, but I do with this recipe. Always.)

Tips for this Fudge Recipe

  • Stir and scrape the sides when mixing – You want to get all that chocolate melted and smooth. Be sure to use a heavy rubber scraper spatula to help you accomplish this. Make sure to scrape all the way down to the bottom of the bowl to incorporate every last bit of chocolate into the fudge mixture. Make sure your fudge is completely smooth before pouring it into the pan. You also want to stir until the sheen is gone. It will become thick and harder to stir, which is a good thing!
  • Pan sizing – This recipe makes a lot of fudge so a 9×13 inch pan works great. A 8-inch square pan probably won’t be big enough to fit it all.
  • Use parchment paper – For easy removal of the fudge from the pan, butter the baking dish, lay the parchment paper in, and then butter the wax paper. Avoid using aluminum foil. It rips easily and can stick to the fudge.
  • Keep it cool – For this fudge recipe you will want to keep it in the refrigerator in an airtight container so it keeps its form. Keeping it at room temperature will make the fudge too soft and the texture won’t be right.
  • Pour it in quickly then leave it alone – Pour the chocolate mixture into your prepared pan. Quickly smooth it into an even layer while it’s still hot. It will begin to set fast and it won’t look as smooth if you keep running your spatula over it. Also try not to bump your pan after it gets set. It will cause ripples in the fudge (I learned this the hard way). Try to quickly set it somewhere it won’t get bumped or moved until it has cooled enough to put in the fridge.
  • Be patient – Wait until the fudge sets before cutting. You will get nice, perfect squares if you wait until it has completely cooled through.
  • Slice before serving – Again, be patient. For fresh, creamy fudge, cut it just before you serve it. Fudge tends to dry out over time. Cut it into 1-inch squares just before you eat it. If you must cut it earlier, be sure to keep the cut pieces in an airtight container or covered with plastic wrap.

Frequently Asked Questions

Can I use Marshmallows instead of marshmallow fluff?

In a word… no. We have had readers try it and they say it doesn’t turn out right. I haven’t tried it before (if it ain’t broke…) but I can tell you it won’t be the same. We have had some say that they have melted marshmallows down or used a recipe to actually make marshmallow fluff but again, we haven’t tried this so we can’t tell you for sure that it will work. We like to keep things simple and always stick to this original recipe.

This has a lot of sugar… is there a way to cut back?

We don’t recommend using less sugar or using sugar substitutes for this recipe. It just won’t set up the way it is supposed to. If you are trying to cut back on sugar I suggest maybe just cutting yourself a smaller piece (if you have that kind of self control).

Do I need a candy thermometer for this recipe?

No, you don’t. If you follow the directions, a candy thermometer isn’t necessary. Please use a timer!

Notes

*We have updated this recipe due to many comments about the difficulty in finding white chocolate bars. The original recipe asked for an eight ounce white chocolate bar and we have substituted that for an additional package of Reese’s Peanut Butter chips. You can still use the white chocolate bar if you can find them. The double peanut butter chips give this fudge a richer peanut butter flavor. 

Recipe tips

  • To remove the block of fudge from the pan before cutting, line the pan with parchment paper or wax paper.
  • Store fudge in the fridge for up to three weeks.

  1. Hi,
    I made this fudge exactly as written and was so excited to try it, but it ended up very very crumbly. What happened? Usually dry crumbly fudge is a result of overcooking.

    1. I’m sorry this didn’t turn out for you! We haven’t had a problem with it being crumbly before. Maybe it was cooked over too high heat?

  2. I’ve made this recipe twice and I’m not sure what is going wrong. I followed the directions as described and both the white fudge and chocolate fudge ended up being very thick after mixing with the evaporated milk mixture. It was so thick that it was difficult to blend the two fudges together. Any suggestions?

    1. It should be fairly thick- you should be able to swirl it right when you put it in the pan. If you wait too long before swirling it will be difficult to swirl. Has it already set up? Did it end up working out in the end?

    1. We haven’t tried that variation, so I can’t speak to how it would affect the taste or texture.

  3. I’m in the UK. What is 1 stick of butter in grams and what us a pkg please; if it means package what is the weight?
    Thanks

    1. 1 stick = 1/2 cup. for the packages in this recipe, they are 10-12 oz. per package. Hope this helps!

    1. The peanut butter chips and chocolate chips range from 10-12 oz. per package– either size is fine. Hope this helps!

  4. I’ve got a couple of questions, as I want this recipe to work for me. I have to say upfront that I am a former professional chef but pathologically incapable of following any recipe as is. The idea of adding such a highly processed ingredient such as marshmallow fluff is anathema to me. What if I were to substitute a Swiss or Italian meringue instead? I realize that you may not be familiar with either of these techniques, but would appreciate any feedback you have. Could you at least give me a ballpark estimate of how much meringue I would need to fluff up the recipe?

    1. Since meringue isn’t as thick as marshmallow whip, I would try a 1:1.5 ratio maybe.. but even then, I don’t know if it will set as well as the whip because the consistencies are different. I feel like the meringue would be absorbed too much. You can always experiment! Sorry I’m not much help on this! I know there are recipes online for homemade marshmallow whip, that may be a better way to go?

    If I use chocolate chips, the “batter” for the fudge is lumpy. Does that mean that I should try to melt the chocolate chips before I add the evaporated milk?

    1. They should melt once you pour the hot milk in. You can try melting the chocolate chips over a double boiler first, but it isn’t necessary. Are you using marshmallows or marshmallow cream (fluff)?

    1. You can try it but the consistency may not match with the chocolate fudge. If you try it let us know how it turns out!

    1. It should yeild appx. 115 1″ squares when measured exactly. Probably closer to 100. It should make 13 rows of 9 squares but I usually cut them a little bigger.

    1. No, sorry, it is 1 jar that is 7-8 oz. That is the typical jar size of the fluff. Hope this helps!

  6. Just to be sure I understand, are you layering the two different chocolate mixtures alternately 3 times each, all in the same pan? Thank you. This sounds wonderful for my church’s Christmas bazaar, and I don’t want to mess up!

    1. That is correct. You can also pour the chocolate one it and then do globs of the peanut butter and THEN swirl. Either way works 🙂

    1. Yes, that should be fine, just make sure that you line with wax paper to avoid sticking 🙂 Hope this helps!

  7. 5 stars
    Loved this recipe!! My first time making fudge and I followed your directions step by step and it came out delicious! It was a huge hit with everyone!! Thank you :)!

    1. Thank you for taking the time to comment! So glad you enjoyed this recipe. I LOVE it with the peanut butter swirl 🙂

  8. Hello,
    I’m sorry but you don’t include the weight of the chocolate chips or peanut butter chips….that would be great!
    Thanks!
    Eileen

    1. Hi Eileen, a package of semi-sweet chocolate chips is 12 ounces (or 1 1/2 cups), and a package of peanut butter chips is 10 ounces (about 1 1/3 cups). Thanks for asking!

  9. I followed this recipe to a T. I don’t know what happened but it is soft and hard to cut because it is sticking to the knife. I am so upset and disappointed. It was way to expensive to just throw away. Ughhh. Does anyone know what happened. It does have a really good taste tho it’s just not the “fudge” I had in mind and definitely won’t be able to give as the gifts I was planning to.
