Mars Bar Square Brownies

Hello everyone! Mars Bar Square Brownies! A delicious new recipe for you today combing my two favourite bakes, a mars bar square and a fudgy brownie! This is a new family favourite which you are going to LOVE!! This layered brownie bake is just incredible and definitely one of my family favourites.

I always get asked how I get my bakes so uniform and straight. The key to this is using a hot sharp knife and wiping the knife in between each cut. To get your brownie layer super straight, once it comes out of the oven use a spatula or a angled palette knife and flatten down the surface very gently. Leave to cool completely then place your mars bar layer on top and smooth out till level. It is important to get each layer as flat as possible so you can get nice sharp cuts.

When you are melting your mars bars and butter it may look like it has split, don’t worry about this just keep mixing in small fast motions and it should all come together. It may be easier to take it off the heat to combine the two. Just keep mixing in small fast motions then it will come back together.
