Mars Bar Cookies

If you put me in front of the single chocolate bar section of the confectionary aisle, there are actually very few choices I would go for. Sure, invite me to dip my hand into a box of Cadbury’s Favourites or Mars’ Celebrations and I’ll go bananas – but they are all the fun-sized chocolates that are gone in a few bites; not like the single regular-sized chocolate bars where you have to like it enough to not get overwhelmed or underwhelmed by it before you’ve even gotten halfway through.

Funnily enough, despite having a massive sweet tooth I will generally go for the ones that are a little more of “a meal”, as opposed to pure sugar and/or chocolate. Twix, balanced out with its crunchy addition of shortbread, the classic KitKat, or a Mars Bar.


I’ve had this recipe bookmarked from the Daily Life food blog for over two years. It was after one particularly sour day at work and on the way home that I was browsing through my phone deleting old bookmarks when I stumbled across it again. Baking is a form of therapy for me, and I knew these Mars Bar Cookies would hit all the right spots. I dashed to the supermarket. And just as my luck would have it, Mars Bars were on special. The heavens had aligned and it was obviously meant to be.


While probably not the prettiest cookies out there, these are close to perfection in texture and flavour. I was a little disheartened when mine didn’t turn out looking like the ones in the photograph on Daily Life, but then I realised it was probably due to my substitution of the corn syrup with brown sugar. But this was quickly cast from my mind upon my first bite. Chewy, earthy, dark, fudgy, bitter, sweet and tangy all at once. These can be accompanied with either a cold glass of whole milk or a strong red. Both work, so it will depend largely on your mood. And the pinch of salt makes them simply sublime.


You will need:

  • 2 eggs;
  • 1 teaspoon of vanilla bean paste;
  • 125g butter, softened;
  • 180g brown sugar;
  • 150g plain flour;
  • 40g cocoa powder;
  • 1/2 teaspoon bicarbonate of soda;
  • 100g white chocolate;
  • 100g dark chocolate;
  • 2 Mars Bars, sliced (this will be easier if they are chilled);
  • A generous pinch of sea salt flakes.

Preheat the oven to 150 degrees Celcius.

Add the eggs and vanilla into a bowl and whisk lightly to combine. In a separate bowl, beat the butter and brown sugar until creamy. Add the egg mixture and beat until incorporated.


Sift over the dry ingredients and stir to incorporate before adding the chopped chocolate.


My mixture was a little too sticky to handle easily between my hands, so I simply scooped up tablespoons of the mixture and deposited them, evenly-spaced, over a lined baking tray. Give them lots of room to spread. Top each round with a slice of Mars Bar and sprinkle over a little salt.


Bake in the oven for about 15 minutes. Allow to cool on the trays, as they will be too soft to handle at first. I know, I know it’s tempting to pick up and sample one of your divine creations, but the wait is well worth it 😉
