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!

3 Musketeers Fudge Brownies

These crazy fudgy brownies are so over the top in the best way possible. The great thing about them is they are easy to make, but a true showstopper of a brownie recipe! You start with a baked fudgy brownie topped with chopped 3 Musketeers candy bars and THEN a layer of homemade fudge! If you’re looking for a classic brownie recipe, this is HALF of what you’re looking for haha. I actually took a huge cheat and used a boxed mix for the base of this brownie recipe. Because, really the 3 Musketeers fudge topping is the star of the show!

Tools You Will Need:

  • 9×9 baking pan to bake the brownies.
  • Parchment Paper. You will see in the photos (they are older and need updating) that I used aluminum foil in the pan. You can do this to, but I exclusively use parchment paper now to line my pans.
  • A Large Bowl. This is to mix up the brownie batter.
  • Rubber Spatula. To mix the batter and the fudge.
  • Cutting Board. You’re going to be chopping up your candy bars.
  • A Sharp Knife. Again, to chop those candy bars.

If You Don’t Like 3 Musketeers…

I won’t hold it against you if you’re not into 3 Musketeers. I think you’re wrong, but I won’t hold it against you lol. The great thing about this recipe is you can use just about ANY candy bar in place of 3 Musketeers. Here are some fun ideas that would be delicious:

  • Peanut Butter Cups
  • Snickers Bars
  • Peppermint Patties
  • Milky Way
  • Mounds


These simple ingredients are all you need! The full recipe can be found at the bottom of the article.

  • Boxed brownie mix. You’re going to bake this according to the package directions.
  • Semi sweet chocolate chips or chopped semi-sweet chocolate
  • Sweetened condensed milk
  • 3 Musketeers bars

How To Make 3 Musketeers Fudge Brownies:

Bake the brownies: Depending on the brand of boxed mix you choose the exact measurements will vary, but most boxed mixes call for oil, eggs, and water and bake according to the package directions. Like I mentioned, I started with a boxed brownie mix.  Feel free to use your own recipe, or absolutely try my brownie recipe (it’s awesome). But this is absolutely a recipe to cut corners on. The fudge topping is the star of the show and the brownies are a secondary act.

Note: Just make sure you bake your brownie in a 9×9 pan. So if you’re using a boxed mix, make sure they aren’t to be baked in a 9×13. Normally you could still bake them in a 9×9, but you don’t want the brownie layer to be too thick for this recipe.

Cool the brownies. Allow the brownies to cool completely before starting the next step. This is a great recipe to prep in advance as well. I make the brownies a day in advance if I’m planning, not that this recipe is very long or complicated, but prepping ahead makes life easier if I have an event or am entertaining!

Chop the Candy Bars: I use the “fun size” 3 Musketeers in this recipe, but you can use full sized bars if you prefer. You need 11 ounces, so however you can make that work is fine! Chop them up into cubes.

Make the Fudge: The fudge recipe is super simple, only 2 ingredients: sweetened condensed milk and chocolate chips. Use a saucepan over low heat to melt, stirring frequently or you can use a double boiler if you prefer. You can even melt the milk and chocolate together in a microwave-safe bowl in 25 second increments, stirring after each until melted and smooth.

How To Store These Brownies:

Just cover the pan you baked the brownies in airtight with plastic wrap or foil and they will be good for up to 3 days at room temperature. If you cut the brownies they will dry out more quickly, so make sure to make them as airtight as possible! You can also freeze them in an airtight container for up to a month for best freshness. Thaw at room temperature.

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

  2. 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! 🙂

  3. 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!

    Yippeee, got a new recipe to try for the nieces this weekend. They are definitely going to be chocolated out! 🙂

    You just reminded my how much I love 3 Musketeers! This looks totally amazing and I would probably have to have two brownies and at least 1 glass of milk to wash it down…dinner maybe? YUM!

  6. 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. 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.
