“Oh Nicole I had the most amazing dessert on Christmas day!”

I braced myself. This had been exclaimed by the friend who returned from the culinary fiesta that is Spain extolling the virtues of cola mixed with red wine and beans cooked with bacon.

“Prostitute brownies!”

Hang on a minute…

“Well, really they are called Slutty Brownies but we didn’t want to call them that in front of the children.”

Because being paid for sex is much more appropriate to discuss in front of children…. I digress.

Five minutes on Google revealed that a Slutty Brownie* is a choc chip cookie base and brownie top encasing Oreo cookies. This was two Christmas’ ago and I have since made these a couple of times; enjoying the transition from confusion to astonishment on friends’ faces as they take the first bite.

Then I got thinking, I could take these to the next level with Tim Tams… but let’s go the full Aussie and bring in the Anzac biscuit. Of course this needs a new name. As awful as it is, a ‘slut’ in Aussie slang is a ‘town bike’ – everyone has a ride. Ahh Australia, all class. Until we started adopting a lot of American words in this country, we called cookies ‘biscuits.’ Being Australian, we needed a slang word for it, hence ‘bickies.’

A quick bit of background for my OS readers:

Tim Tams are Australia’s favourite biscuit. Composed of two layers of chocolate malted biscuit with a cream filling in the centre and coated with chocolate. They come in different flavours and are pretty rocking.

Anzac biscuits were sent to our soldiers during World War One. The term ‘Anzac’ is protected under Australian law and to call a biscuit an Anzac biscuit you must stick to the original recipe of rolled oats, flour, desiccated coconut, sugar, butter and baking soda. Yep, we use terms like ‘town bike- everyone gets a ride’ and regulate our biscuit recipes. Welcome to the land down under.

Back to the #foodporn. Oaty caramelly biscuits with a chocolate coated malty biscuit on top and covered in a layer of fudgy gooey brownie. If you are offended by the name just call them “oaty caramelly chocolatey malty gooey brownie things,” just make sure you whip up a batch šŸ˜‰

These are remarkably quick and easy to make and the majority of the ingredients for the Anzac biscuit layer are the same as in the brownie layer. I used recipes from two very talented women to create this beast. The Anzac recipe is a fairly traditional one from Sandra at The $120 Food Challenge and the brownie recipe is a variation on Nigella Lawson’s everyday brownie.

Best made the day ahead, these can be whipped up from go to whoa in forty minutes if you want oozy foodporn brownies, forty-five if you want them neat and sliceable. We both know which I think you should go for.

Take them to a BBQ where after a few cordials their name is the funniest thing in the world.

Can you feel your arteries clogging? šŸ˜‰

*I want to add a little history here. The original ‘Slutty Brownie’ was actually called the Ultimate Chocolate Chip Cookie nā€™ Oreo Fudge Brownie Bar and was created by a wonderful blog called Kevin and Amanda. A few months after they published their recipe The Londoner published it without linking back (tsk tsk) and gave it a very catchy name. The internet went wild and she became known as the creator of the Slutty Brownie, when really she is just the namer. Please check out Kevin and Amanda for amazing recipes, great camera tutorials and some seriously wanderlust-inspiring travel posts.

Also, I don’t want you to be offended by my naming. It is tongue-in-cheek and I am not intending to be derogatory. I like to have a bit of a giggle at Aussie slang šŸ™‚

  1. So much Australian in there, I might have to whip up a batch for Oh-straya Day! It seems almost rude not to! The photos are screen lickingly good!

  2. That is so interesting about the londoner – I have seen comments she has left on peoples blog berating them for not properly crediting her for slutty brownies..
    Anyway all that aside I freaking love Tim Tams and ANZAC biscuits so would much prefer the “Town bike” option – clever idea.

  3. um…..How have I not come across your blog? As a fellow Melbournian, I hang my head in shame.

    I now raise it to praise you for making this epic creation. Nicole, this needs to go viral.

    Cannot wait to follow on! šŸ™‚

I love to hear from you...
