Beccy's Marvellous Mars Bar Cake

Recipe prepared by Mollie [9] with a little help from Ben [4]

"Hi. I've been trying to find a receipe for mars bar cake and was wondering if you had one. Any help would be greatly appreciated. Thanks, Jody", October 25th, 2005

I can only assume that Jody, who wrote to me last week looking for a Mars Bar Cake recipe, had read a previous post of mine when I mentioned, in passing, that my sister, Beccy, had a recipe she might be willing to share. As luck was have it, not only was I on the verge of flying off to Ireland to stay with the keeper of the recipe, a couple of her children, Mollie & Ben, agreed to be 'blog models' and make the Mars Bar Cake for me live, so you can all see how it is done.

1) Buy a pack of six Mars Bars.
In the US, Mars Bars are called Milky Ways so buy those instead.

2) Break up the six Mars Bars [Milky Way US] into small pieces.
"This is sticky work", said Ben.

3) Collect the pieces in a large microwave-friendly bowl.

4) Weigh 6oz of butter. (Use real butter, not margarine)

5) Put the butter in the Microwaveable bowl along with the Mars Bar pieces.

6) Microwave the Mars Bars and Butter until they are melted. Mollie achieved this look with 4 minutes on high. Adjust according to the strength of your microwave oven. Alternatively, melt the two ingredients together in a heat-proof bowl over a pan of boiling water.

7) Start to stir the Mars Bar and Butter mixture together.

8) The mixture looks lumpy to begin with, but as Mollie beats it, it gets smoother and smoother.

9) Measure 6oz Rice Krispies or store-brand equivalent into the bowl with the blended butter and Mars Bar mixture.

10). Stir until all of the rice krispies are fully covered.

11) Transfer the mixture into a large buttered dish, tin or pan.

12) Pat down the mixture until the top is level and smooth. Mark into squares with a knife and then put into the fridge to set.

13) If you are the chef, you may now lick the spoon.

PS. I think Mollie, who seems to fit quite easily into the kitchen environment, might be set to take after her Auntie Sam. This isn't her first appearance on this blog. Do you remember when she made Fairy Cakes?

Archive Alert! On this date in 2004 it was the start of a series of Bakesales for Charity when I experimented with a great little recipe from Clotilde.

    This is naughty but nice. I can thoroughly recommend it.

    Now I know what to do with that bag of Milky Ways leftover from Halloween. Thanks! Great blog models, too. :-)

    Wait, step 6: Microwave until it looks like a plate of melty foie gras? Heh.
    Also: Hello, Sam's mum. ;)
    (gosh, it sounds good)

    I do remember when she made the fairy cakes! What a fun post. It looks like you are having a yummy trip so far. I'm just so relieved you saw the cowboy pictures before you left. : )

    And I can't believe I am actually, almost, kind of, sorta considering (and admitting I am considering) Sid & Nancy as names for the new llamas. . . : )

    I bought some with me from ireland to bristol so my mum (and I) have actually tried the very Mars Bar cakes made during this photoshoot. They are deliciously buttery - be sure to keep them in the fridge.

    Elise - enjoy - they are a very popular type of rice krispie cake with all my adut friends!

    Cookie crumb - mum says hello. I told her about the gammon and pineapple jokes at her expense and she hasn't sent me to my room with no dinner, so I cant be in too much trouble.

    Farmgirl. Sid and nancy. C'mon - that is just the perfect name for those too cool llamas!

  • At 3/11/05 07:57, Blogger Nic said…

    Adorable - and tasty! Everyone knows that licking the spoon is the best part, too.

  • At 3/11/05 09:20, Blogger Lady Amalthea said…

    I agree; I always insist on being the one to lick the spoon. Your niece and nephew are really adorable, by the way.
    And I'm curious; what's the consistency of this like? Is it very dense of more brownie-like?

  • At 3/11/05 12:10, Blogger Joycelyn said…

    sounds fantastic...and models look positively angelic too...for some bizarre reason, this post has me craving a deep fried mars bar

  • At 3/11/05 14:56, Blogger shuna fish lydon said…

    I'm so glad someone else brough up Fried mars Bars.

    What it is with the specific fetishistic fixation with Mars Bars in the UK anyways?

  • At 5/11/05 08:45, Blogger Shauna said…

    Now, how can I resist this post? Two adorable children in Ireland, melting Mars bars, "This is sticky work," and a loving auntie? Me, I wouldn't know anything about that one.

    Great job, Sam. I hope you're having a fabulous holiday.

    Wonderful pictures! I guess this has to be my favorite entry on Becks & posh ;)The kids are so into it - it has to do with the genes, hasn't it... ;)

    Hmm.. definitely have to try that some time. Thnx ;-).

  • At 10/4/06 09:12, Anonymous Anonymous said…

    A really decadent and scrumptious addition to this recipe is to put melted chocolate on top of the cakes (Galaxy chocolate is, in my opinionm, the bestest!).

    It makes a super-dooper recipe even super-dooperer!

    Deep Fried Mars Bars are a Scottish invention, so you would not find them in London.

    Nice idea putting the layer of chocolate on the top - I'm gonna go one step further for Easter and put Mini Eggs (yummy Cadburys chocs) on the top.

  • At 12/4/06 07:14, Blogger Sam said…

    you guys are outrageous! galaxy chocolate and mini eggs, oh yes!

    In Australia we call this Mars Bar slice, but we smooth melted chocolate over the top, and when set, cut into squares. Always a hit with everyone down under.

    This recipe reminds me of being a kid and my mum making it. Her recipe was the exact same, including the layer of chocolate on top. But aswell as adding butter to the melted mars bar mix, she put in 2 dessertspoons of syrup. Yum yum!

    thanks i've been looking for this recipe. my auntie gave it to me a few years ago and i lost it. When I made it before i put melted chocloate on the top.

    I can't believe you let your children eat something with so much saturated fat in it.

  • At 21/6/07 08:25, Anonymous Anonymous said…

    To be eaten on special occassions only due to the high fat and sugar content. Flapjacks are more nutritious as they have fibre from oats. Take a look at the ingredients of a mars bar !

    Sounds great! I'll have to try that one day...

    Great recipe. Loved the photos of kids having fun cooking in the kitchen and no doubt enjoying the yummy taste! I was actually looking for a mars bar cake recipe. This recipe was more of a slice. Nonetheless it was good reading.

    Deep fried mars bars are not a Scottish invention. They were first created in Middlesborough which is in the North East of England. Yes, and haggis dont fly either.
