Mars Bar Slice - A Super Easy Traybake Recipe

Mars Bar Slice - or Mars Bar Traybake - is yet another one of those classic cakes you’ll see in cafes across Scotland. We can’t resist a slice whenever we see one (which is far too often!) so we decided to make our own. Mars Bar Slice is just two layers. One is melted Mars Bars mixed with Rice Krispies and butter, and the other is a layer of chocolate on top. That’s it. It’s that easy.
