How to Make Mars Bars Squares

Sometimes simple can be simply the best. Returning to amazing tasting but completely bad for you treats can sometimes be so soul satisfying.

Sometimes it’s nice to forget the fancies and go back to the basics. Mars Bar Squares are the basics.

Basic tasty.

Basic melt in your mouth chocolate.

Basic takes a few minutes to make!

Basic get out of bed at 1 am because you remembered they are in the kitchen. These and a glass of milk at 1 am in your kitchen makes up for any kind of day you had.

Or more like sneaking into your sisters kitchen to eat them, since I made these in her place while visiting.

What could be a greater start to a recipe than melting chocolate bars with butter? I can’t think of anything to be honest. When that’s done, mix the Rice Krispies in with them, then transfer to a well greased 9×9 pan. Melt the chocolate and butter for the topping, then pour it on top. Cool in the fridge then cut into pieces and serve.

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

  1. 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!

  2. Cleta says

    Are these full size candy bars or the smaller snack size?

  3. 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

  4. 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.

  5. 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.

  6. Joan says

    These look wonderful. i would like to make these for a bake sale. How ling do you think they would keep?
    Thanks5 stars

  7. Lyla says

    Should the chocolate chips be milk chocolate or semi-sweet? Thanks!

  8. Kory says

    I just did what the directions said and they were great!5 stars

  9. Rosaline Linhart says

    you can bring down the cost of making these by buying the Mars Bars at the Dollar store….

  10. Heather Averill says

    Mmm… I love these. Made them at Christmas. 🙂

    5 stars

  11. The Kitchen Magpie says

    Laura Van Scoyk-Myers Milky Way would be the closest bar to it..

  12. 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

    5 stars

  13. 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

    5 stars

  14. 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.

    • Cocapp says

      Yes. I prefer them that way. My grandkids say it’s to sweet with the frosting.

      5 stars

  15. RosemaryBarryTargett says

    Can you freeze those mars bars squares thanks.

  16. Rebecca Cooper says

    they had knockoff mars bars at the $store 🙂 2 bars for $.50. Guess what I just made!

  17. SherriH67 says

    Thank you for sharing this very delicious and oh so addicting recipe!

    5 stars

  18. 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.

  19. Michelle Kehoe says

    the best square I ever put inside of my bewwy………. I <3 these!

  20. 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!

  21. 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!

  22. 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…

  23. Kevin says

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