A spooky twist on the classic Scottish tray bake. Mummy Mars Bar Slices are sure to please monsters of any age!
Last Halloween I shared a recipe for Monster Rice Krispy Squares, which I’ve been making since my kids were just wee. This year, I again wanted to share something spooky and equally as tasty. After a bit of brainstorming, I came up with Mummy Mars Bar Slices.
Taking inspiration from our much-loved Mars Bar Slice recipe, I used the same formula for the base, whilst adding a Halloween inspired spooky finish.
Think of them as sweet Scottish treat to add to your spooky-season baking repertoire.
You make them the same way you would any good Mars Bar Slice. Start by melting your Mars Bars & butter, before adding the rice crispies, to make that iconic crispy but chewy base.
Unlike a traditional Mars Bar Cake, we then use white chocolate as the topping. And instead of spreading an even layer, you want to drizzle it on top to look like a Mummies bandages.
The edible candy eyes are almost enough to bring these Mummies back from the grave. Alive or not, they are a sweet treat the whole family will love.
Butter or MargarineEither will do and it’s personal preference to which you choose. The butter/margarine helps thin out the Mars Bars whilst melting, and stops them from becoming overly claggy.
Mars BarsAn essential ingredients in any Mars Bar Slice! Whatever size Mars Bar you use, just make sure they come to the total weight listed in the recipe.
Rice KrispiesThey can be branded or store-own rice crispies, it doesn’t matter at all. They – along with the melted Mars Bars and butter/margarine – are what makes up the bulk of this Mars Bar Slice. The perfect combination of sweetness, sticky caramelly-nougat and rice crispies crunch.
White ChocolateTo transfer these into a Halloween Mars Bar Slice, we use a drizzling of melted white chocolate, to create the look of bandages. Simple but spookily effective!
Edible EyesYou can now pick up a pack of edible candy eyes in most big supermarkets – and they are ideal for these Mummy Mars Bar Slices, as well as our Monster Rice Krispy Squares. But if you are struggling to get your hands on some, you could use a couple of chocolate chips as eyes instead.
• When it comes to melting your Mars Bars, you’ll never have a completely smooth mixture, as the nougat doesn’t melt in the same way as the chocolate & caramel. You can break it up a little with the back of your spoon/spatula but don’t worry too much, as it will mix through your rice crispies just fine.
• When it comes to drizzling your white chocolate, you can simply do this by drizzling it with a spoon. Or, if you prefer a neater finish, you can pop your chocolate into a dispoable piping bag and pipe it on.
• If you can’t get your hands on some edible eyes, simply use some chocoalte chips for eyes.
