Start by preparing the chocolate brownies – Melt 100g of the butter and chocolate over a medium heat in a bowl above a pan. Stir in the brown sugar, add the medium eggs and then add the vanilla essence. Add the self raising flour and mix well.
Pour the mixture into a greased dish that is of an appropriate size for your airfryer.
Cook in your airfryer for 15 minutes on a 180c.
While the brownies are cooking it is time to make the caramel sauce – Mix the caster sugar and the water in a pan on a medium heat until the sugar is melted. Then turn it up and cook for a further three minutes until it has turned a light brown colour. Take off the heat and then after 2 minutes add your butter and keep stirring until it is all melted. Then slowly add the milk.
Set the caramel sauce to one side for it to cool.
When the brownies are ready chop them into squares and place them on a plate with some sliced banana and cover with some caramel sauce.
I know not everyone is allergic to nuts like me so if you are into nuts and have no allergies then add 50g of walnuts to your brownie mix at the same time as transferring it into a container before going in the air fryer.
