No-Bake Traybakes

Mars Bar Traybake

I’ve never been a big fan of the Mars Bar. I would never buy one in a shop. Although if you offered me a mini Mars Bar, I probably would take it. For some reason, I think they taste better than the full-sized bars. But, the Mars Bar Traybake is a different story altogether. Somehow, a melted Mars Bar mixed with Rice Krispies (other puffed rice cereals are available) transforms it into a very yummy, crispy, chewy treat that is hard to refuse.

As I live in the US these are, in reality, a Milky Way Traybake. The equivalent of a Mars Bar is called a Milky Way bar over here. And the nearest equivalent to a Milky Way is a 3 Musketeers bar. Snickers is still a Snickers. In the interest of research, I purchased an imported Mars Bar and compared it to a US Milky Way bar. And, to be honest, I couldn’t really taste much of a difference between them. Perhaps someone with a more refined palate than mine would think differently, but I figured that these would make an appropriate substitute for my recipe.

So, whatever you want to call it, what you want for this recipe is a chocolate-covered, nougat and caramel bar.

I have very little baking advice for you on this one, as it really is very simple. Just be prepared for the melted Mars Bar mixture to look a little lumpy at first. When you start to melt your ingredients, the butter will melt and the chocolate will melt, but it takes a little longer for the nougat to melt. Stick with it and it will get there in the end. And you will have a lovely, thick, chocolate and caramel sauce to mix with your Rice Krispies. Check out my YouTube video for this Mars Bar Traybake as I show you what the melted mix looks like when you’re halfway there.
