    Chocolate brownies are an absolute favourite in our house - and they're my go-to recipe whenever I need a quick and yummy chocolate treat. BUT! Sometimes you just want an adults-only treat that can't be pinched by a cheeky toddler... which brings me to these fabulously delicious Baileys Brownies. Just think... your favourite rich chocolate brownie recipe but made with Baileys Irish Cream, with a Baileys chocolate fudge frosting and a sprinkle of sea salt on top. Can I get a heck yes!?

    Chocolate brownies with frosting being cut up on a chopping board.

    A one-bowl boozy Baileys brownies recipe... that's as easy as 1.2.3!

    These brownies could not possibly be any easier to make! All it takes is 3 simple steps.

    Step 1 - Melt the chocolate and butter in the microwave

    Step 2 - Whisk through the Baileys, vanilla extract, caster sugar and eggs

    1 bowl of Baileys irish cream, 1 bowl of caster sugar, 2 eggs and a bottle of vanilla extract.

    Step 3 - Fold through the plain flour, bi-carbonate soda, cocoa powder and a pinch of salt

    A bowl of plain flour, a bowl of cocoa powder and a sprinkle of bi-carbonate soda and salt.

    See... 3 super simple steps to the perfect brownie!!! And then it's time to make the Baileys chocolate fudge frosting!

    Baileys in the brownies... tick!

    This recipe could not get any better, could it!? And trust me... the frosting is going to BLOW YOUR MIND!

    This frosting is AMAZING... and all you'll need is 1 bowl, a whisk and a few basic ingredients:

    • butter
    • vanilla extract
    • pinch of salt
    • cocoa powder
    • icing sugar
    • Baileys Irish cream (check out our homemade recipe here)

    Simply whisk them all together in a bowl until smooth and creamy, spread over the still warm brownie and sprinkle with extra sea salt flakes (the salt really brings out the chocolate flavour... trust me on this one!).

    How to store brownies

    You can store brownies in an airtight container at room temperature for up to 5 days. It's best NOT to keep them in the fridge as they'll dry out. Brownies are a great option when you need to make a recipe a few days ahead of time as they'll still taste AMAZING!

    You can also freeze brownies for up to 3 months in an airtight container (or wrapped well in foil and covered in plastic wrap).

    Notes

    RECIPE TIPS
     
    This recipe is made with alcoholic Baileys Irish Cream and is therefore an adults-only dessert. 
     
    If you don't have a microwave, you can melt the chocolate and butter in a saucepan over low heat on a cooktop. 
     
    There's no need for a stand-mixer or beaters - simply whisk the wet ingredients together and then fold through the dry ingredients with a spoon or spatula. 
     
    Adding sea salt to sweet recipes - sea salt really brings out the flavour of sweet recipes (especially chocolate recipes). The sea salt sprinkled over the top of this brownie adds an amazing contrast flavour to the sweet and creamy brownies and frosting. 
     
    You can store brownies in an airtight container at room temperature for up to 5 days. Do NOT to keep them in the fridge as they’ll dry out. These can be made ahead of time. 
    You can also freeze brownies for up to 3 months in an airtight container (or wrapped well in foil and covered in plastic wrap).

      I've made these a few times and they are great! I was just wondering if I could switch the caster sugar to soft brown sugar?

        Absolutely! They'll have quite a different texture (more chewy) xx

          If I were to want to warm these up but worried about how the topping would go, have you got any recommendations

            Hi Kelsey, yes the frosting does go soft and melt a little when served warm!

      Really want to make this recipe looks so simple and tasty, but I gotta know. Can I switch the butter for Margarine?
      A bit of a dairy issue. I know there is dairy free Baileys and dark chocolate is good.
      It's just the butter thats the stopping point.

        Hmmm I haven't personally made these with margarine so I wouldn't like to say sorry!

      These are delicious, I’ve made them a few times now. I belong to a Cake Decorating association and was asked to make them for a sweet treat at their lunch. There wasn’t even one piece left to take home
