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…

This would be 5 stars if you cut the ganache layer by half. As is, is way too thick, and I love a rich chocolate dessert. Heck, I used Death By Chocolate Brownies recipe. Hmm, thinking half ganache and Snickers next time.

How many servings it makes and can brownie be reheat in the microwave?

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. 🙂

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!
