The Ultimate Mars Bar and Maltesers Slice (2024)

Oh my goodness, if you didn’t think Mars Bar Slice could get any more indulgent, then you just HAVE TO try this Ultimate Mars Bar and Maltesers Slice!

I just can’t help myself when it comes to playing around with recipes, and this ultimate Mars Bar and Maltesers Slice is the delicious result of this addiction! It’s like a pimped out version of myMars Bar Slice and Maltesers and Mars Bar Slice recipes combined, with a total of FIVE Mars Bars, TWO blocks of Milk Chocolate and a bag of Dark Chocolate Maltesers (so it’s not for the dieters out there) are combining to create a rich and decadent slice.

It took all of my restraint to stop myself from eating more than one piece of this slice, so I sent the remainder of it to work with my husband to share with his colleagues. The only complaint I received was that he couldn’t stop himself from eating it at work, and I shouldn’t make it again, so a compliment really!

This slice takes no time at all to make, regardless of whether you are using a thermomix or not, and I promise once you have tried it, you will never go back to making Mars Bar Slice any other way!
