Mars Bar Flapjacks

There are some days when I have a look through my kitchen cupboards and I do not quite have enough ingredients to make what I actually intended, so I end up having to improvise. I found some porridge oats so I thought I could make some flapjacks but I did not have any golden syrup or honey! BUT I did have some Mars Bars which I know work in place of syrup in these homemade Toffee Crisp Bars, so I wondered if they would work in a flapjack!

Would they – could they work?

There is o nly one way to find out – read on and find out how I made these easy and very tasty ┬áMars Bar Flapjacks.


Mars Bar Flapjacks
Cook time
Total time
Recipe type: desserts
  • 200g Mars Bars
  • 150g unsalted butter
  • 200g porridge oats
  1. Pre heat the oven to 160 oC / 140oC (fan)
  2. Grease and line an 8 inch square baking tin
  3. Place the butter and Mars Bars in a pan over a low heat and melt together
  4. Add the oats and mix well
  5. Pour into your prepared tin and place in the oven
  6. Cook for about 30 minutes until golden brown and cooked
  7. Leave to cool and then cut into squares


These tasted nice – possibly not as sweet as a standard flapjack but I do not mind that to be honest. Such a quick flapjack to make and possibly not as sugarific as they normally are either. Give them a try next time you fancy a flapjack – I think you will like what you eat!

  1. I always love the ‘what’s in the cupboard’ emergency bakes the best. My Chocolate Beetroot cake has nesquick instead of cocoa powder and it’s a delight! These sound absolutely perfect!

  2. These take me back to the Mars Bar rice krispie cakes we used to make as Girl Guides! I will be trying these out with my 7 year old as I’m sure she’d love making and eating them. Pinned it to try later.

  3. Great recipe for cooking with Easter eggs! I used the mars bars from my egg, and melted the egg on the top. Delicious, and went down very well in the office!

Thank you for taking the time to leave a comment, a virtual cup of tea and slice of cake awaits you x
