Mars Bars Squares are a classic treat that is always a hit! Melted Mars Bars, ( or if you are in the USA, use Three Musketeers or any nougat bars that are like it) combined with butter and rice Krispies make the easiest and most delicious bar ever!
How to Make Mars Bars Squares
Sometimes simple can be simply the best, and it’s nice to forget the fancy desserts and go back to the basics. Mars Bar Squares are the basics.
What could be a greater start to a recipe than melting chocolate bars with butter? I can’t think of anything to be honest.
- Melt the butter and the Mars bars together in a pot.
- When that’s done, mix the Rice Krispies in with them, then transfer to a well-greased 9×9 pan. Pat into an even layer.
- Melt the chocolate and butter for the topping, then pour it on top. Cool in the fridge briefly to set the chocolate topping then cut into pieces and serve.
Mars Bars are Perfect for Parties!
These are my entire family’s go-to dessert when we are asked to bring a treat to a party, or whenever we have a family picnic!
How to Store Mars Bars Squares
Keep them in a cooler in the hot weather and they will stay perfect, and if you are at home simply store them on the counter.
For longer-term storage you can store them in the fridge, they do get a litter harder but that has never stopped us! Also, they are rarely stored that long as they tend to go quick!
Mars Bars Squares are THAT easy, you guys! It’s no wonder my Mom made these all the time when I was growing up – and she still does! Except she leaves the chocolate off the top and I keep telling her that it’s a crime against all things delicious to do that. They are good without the chocolate, but they are AMAZING with the chocolate topping.
Happy non-baking up these Mars Bars Squares!
Love,
Karlynn

Donna says
How many grams of butter did yous use?
Gisele says
Made this recipe tonight, had my husband sample a piece. He said it was amazing. I made a double batch because I knew a small pan wouldn’t be enough. This recipe is definitely a keeper.
kirsty says
Just use Milky Ways (not 3 musketeers as suggested, they don’t even have caramel in them) . LOVE this stuff, made it since a kid.
Karen says
Once the recipe is made, and cut into pieces, do you keep this in the fridge or on the counter? Can it be put in the freezer? Thanks
Marilyn says
I have been making these for years but I use cornflakes instead of Rice Krispies. They are always a hit! I’ll have to try Rice Krispies!
Cleta says
Are these full size candy bars or the smaller snack size?
Di says
My mother made these for us when we were children. Must be at least 60 years ago. Proper chocolate melted on top is best. We use either Cadbury or Galaxy.. They remain a special treat for us, our children and grandchildren
Gisele says
These are delicious and have been making them for years, instead of chocolate chips for the topping I use Aero chocolate bars. Family loves them.
Antionette Shelby says
Mars bars were discontinued in the US or at least I can’t find them and I live in Las Vegas now so I’m gonna try these with Snickers since I love nuts of all kinds.
Joan says
These look wonderful. i would like to make these for a bake sale. How ling do you think they would keep?
Thanks
Lyla says
Should the chocolate chips be milk chocolate or semi-sweet? Thanks!
Kory says
I just did what the directions said and they were great!
Zura says
Once the mars bars and butter have melted..do we mix in the rice krispies straight away while the mixture is still hot? Or do we leave it to cool off slightly before mixing in the rice krispies? Thanks
SUE says
Great recipe thanks!
Rosaline Linhart says
you can bring down the cost of making these by buying the Mars Bars at the Dollar store….
The Kitchen Magpie says
Yes!!! Great tip!
Heather Averill says
Mmm… I love these. Made them at Christmas. 🙂
Mary Ann Hyndman Smith says
I think a Milky Way would work.
The Kitchen Magpie says
Laura Van Scoyk-Myers Milky Way would be the closest bar to it..
Krista Girvan says
These are the best! My mother in law introduced me to them. I only make them at the holidays though or I’d eat them all the time! Lol
Tiffany Kautz says
My absolute favourite square- my grandma used to make this for us as kids, and I now make this for my own family…..and end up eating A LOT of it \U0001f601
Laura Van Scoyk-Myers says
I’m guessing it’s close to our Milky Way? Or is it more like snickers? I’m pretty sure I’ve had a Mars bar before but they were discontinued here awhile ago.
Meera says
Can these be made without the chocolate topping?
Cocapp says
Yes. I prefer them that way. My grandkids say it’s to sweet with the frosting.
RosemaryBarryTargett says
Can you freeze those mars bars squares thanks.

Rebecca Cooper says
they had knockoff mars bars at the $store 🙂 2 bars for $.50. Guess what I just made!
Anaya says
I got 2 for 60p
SherriH67 says
Thank you for sharing this very delicious and oh so addicting recipe!
Deb Hove Johnson says
I have a similar recipe that calls for 8 milky way bars, 2 sticks of butter and rice krispies (same as in rice krispie treats recipe) in a 9×13 pan. Then a pkg of chocolate chips and stick of butter melted for topping. SO YUMMY but we call them triple angioplasty bars.
Michelle Kehoe says
the best square I ever put inside of my bewwy………. I <3 these!
Lindsey B. says
Thank you for this recipe! Someone at our old church used to make these all of the time for tea time and I’d lost the recipe.
I think Milky Way bars are probably also a good substitute for Mars bars, if you can find them!
Vanessa says
I was wondering if I could substitute Crisco for butter (as I am out of butter)?
Karlynn says
Ohh, I am going to say no. Crisco just isn’t the same as butter, especially in this recipe!
Marilyn the nurse says
Saw this recipe on the Stir by CafeMom but can not find Mars bars in our area. I can’t remember if they taste like Snickers? Could you suggest a substitute bar? Thank you!!!
Karlynn says
Mars bars don’t have nuts in them…hmm. You know what? Three Musketeer bars are close, but no caramel in them. Snickers would work if you want peanuts in the squares…
Rebecca says
You could always try milkyway bars.

My wife’s pregnant, so I can and will not show her this post.
