I am a massive fan of Mars Bar Slice. It always reminds me of childhood. I think it was a staple at all kids parties in the 90s here in Australia.

This is my super easy festive spin on it. My son took this batch to school today for the class party. Not healthy in the slightest but a massive hit! 

Note to self: Take a better photo of this one.

If you make them please come and share a photo on our Facebook page or come and say in our Facebook group. I would LOVE to see them!
