3 Musketeers Fudge Brownies

3 Musketeers Fudge Brownies are a chewy brownie, topped with a thick layer of fudge, loaded with chopped 3 Musketeers bars. This is for the major chocolate lover!

If you don’t enjoy chocolate, like my crazy-butt husband, please step away from the computer now, because today we are going full-send.

If you’re looking for a classic brownie recipe, this is half of what you’re looking for. I actually took a huge cheat and used a boxed mix for the base of this brownie recipe. Because, really the fudgy, 3 Musketeers topping is the star of the show!

These 3 Musketeers Fudge Brownies are crazyoverthetopinyourface brownie genius, and since I am incapable of humblebragging, I will just brag. They are a riff on my Rolo brownies that I made last year and I was pretty sure they couldn’t be one-upped…until today.

Again, I started with a boxed brownie mix.  Feel free to use your own recipe, because you guys constantly remind me you like your own brownies.  I get it…I do too. It’s just in this case the brownie is basically a vehicle for the 3 Musketeer Fudge, so I took a short-cut.

Just make sure you bake your brownie in a 9×9 pan…so if you’re using a boxed mix, don’t get all Family-Size on me.  Just a normal box. Also, don’t get hung up on ounces in the brownie mix or anything.  It really doesn’t matter as long as you bake them in a 9×9.

The topping is a simple fudge recipe made with melted chocolate and sweetened condensed milk, loaded with chopped 3 Musketeers bars…

  1. Today is the last day?! What? Why? I was hoping this was going to be a regular thing. I think I’ll make these for my coworkers. There’s nothing they love more than rich chocolate desserts with a familiar flavor (candy bars) thrown in. Thanks for keeping me popular at work.

      Sounds like they are exactly the same! Also, the fun thing about this recipe, is you could really sub in any candy bar you like 🙂

    Making them right now! Should they be kept in the fridge because of the fudge? Or is it ok to leave them out at room temp?

  3. My oven is preheating right now! Anything to give me an excuse to open up a can of sweetened condensed milk…I’m all over it!

    I’m missing candy week already…..extend it please! Encore! Encore!

  4. I was totally sure that you would use the 3M’s in a chocolate Krispie treat (after you told me to reguess when I was sure the straw meant a 3M milkshake)…you had me fooled! These look amazing! And I totally make fudge that way too, just way too easy not to! So, yup, these are perfect!!

  6. 3 Musketeers were always my favorite candy bar as a kid…that mousse-y nougat center…LOVE. I’m thinking these brownies need to be done with a 3 musketeers/reese’s mix. I just got chills.

    This candy week with the 3 of you bloggers is absolutely killing me. All of these recipes look fantastic! I’m making myself wait until the end of the week and then pick 1 (or 2) recipe to try first!

  8. I am thinking of making these and shipping them in a vacuum sealed bag, but I am worried about the fudge on top melting. Did it stay pretty solid at room temp or did they need to stay refrigerated?

    1. shelly

      Depends on the temperatures. When I made them we were having a warm spell (in the 80’s) and the fudge got soft. Not too soft for home-eating, but for shipping, maybe, yes…but if the temps are cooler you shouldn’t have a problem. Another thing you could do is add more chocolate chips to the sweetened condensed milk/fudge mixture..this will make the fudge slightly more solid, as opposed to being a soft fudge.

    I made the Rolos ones and brought them to work. Everyone went NUTS! One coworker has been on a diet, and she’s having a cheat day on Monday so has demanded they be made again, so I said I will make these this time. Can’t wait! Thank you!

    Wow! This was my second Pinterest recipe ever. It was delicious. Such chocolate goodness. I also keep them in the fridge. So easy yet look gorgeous. Found you through Recipe Girl. Great site! 🙂

    Just made these brownies…they’re amazing! Super chocolate deliciousness. Can’t wait to try out more of your recipes this summer!

    These are not good. The fudge layer is way too much. I love chocolate and this was too much for me. I only used 1/2 of the chocolate chip/sweetened condensed milk layer.

      I’m looking to use a ton of mini 3 Musketeers bars I have leftover from Halloween and stumbled upon this recipe. It sounds good, but your comment was exactly my concern. It sounds incredibly rich; I’m considering adding some sort of salted cookie layer between the brownie and fudge; also halving the amount of fudge. Thanks for your feedback, it helped me decide how I’d like to personalize this recipe. 🙂
