    Recipe Hints and Tips

    • You can use 'Fun Size' Mars Bars for this recipe. Please note you will need approximately 250grams.
    • It is REALLY important that you let these Mars Bar Brownies cool completely in the cake tin before removing/slicing into pieces as the cooling time will help the fudgey brownie centre to set.
    • To store, place in an airtight container and store in a cool dry place (pantry) for up to three days. These Brownies can also be stored in the fridge, allow the brownies to come to room temperature before serving.
    • To freeze, place in a freezer safe container and freeze for up to one month.
    • You can serve these Mars Bar Brownies at just about any occasion (and they are also an amazing dessert when heated slightly and served with ice cream or our Chocolate Fudge Sauce), however they also make a really lovely (and very much appreciated!!) homemade gift - simply pop a few pieces of brownie into a cello bag and decorate with a ribbon.
    What makes Brownies Fudgey?

    A higher ratio of fats (butter, chocolate) to flour helps to give brownies their fudge like texture.

    What is the best thing to make Brownies in?

    Baking brownies in a metal container will help you achieve best results. For our Brownie recipes we like to use a 20cm square baking dish.

    Can you freeze Brownies?

    Yes, you can freeze brownies when stored in a freezer safe container or bag for up to one month.
