Hazelnut Chocolate Brownie with Chocolate Mayonnaise

Hazelnut Chocolate Brownie with chocolate mayonnaise – Yes, it’s happening. So super simple to make and yummy. A great little afternoon tea treat when guests are around or a luscious dessert square served with fresh berries as we did last night around at friends – Given I am gluten free and the little man is gluten / cassein free, I always volunteer to make dessert. It takes the pressure off the host and means everyone can partake in the joy of dessert when celebrating with friends.

This is very low sugar and no starch, so it’s a great one for GAPS, IQS being fructose free if desired or Paleo purists who avoid buckwheat / tapioca.

Why the egg yolk? Well, My grandmère used to make a delicious ‘mayonnaise au chocolat’ in her day. One of my favourite desserts. It was laden with sugar back in the day though, so this is a healthier version with healthy fats increased for satiety and deliciousness! The silkiness of the egg yolk creates an unparalleled result. It emulsifies all the ingredients beautifully. Taste it and you will see – Double this recipe to make little mayonnaise au chocolate bowls for an easy, small sweet something at the end of a meal too. By no means restrict this to icing!

Is raw egg safe? Well, the jury is out on that. My take is if you know the producer and it is pasture raised AND organic (I say that because pasture raised hens are much healthier, whereas organic certified eggs can still technically keep far too many hens cooped up which can breed disease, thus organic not being enough.) then I say yes, but if you don’t feel comfortable, you’re no1. so just leave it out.

I hope you enjoy the recipe. Are you a chocolate fan? Why not try my chocolate coconut cupcakes, chocolate pudding with gooey bits or “I can’t believe it’s not Milo drinking chocolate powder? They’re all gluten free and nut free with dairy free options and the cupcakes and milo are / can be egg free. Hopefully that means lots of peeps can tuck in at your next celebration!
