Preheat your oven to 180°C fan forced and spray your mini muffin tins with oil.
Whack the melted butter, caster sugar and brown sugar into a bowl and give it a good mix.
Add the vanilla and eggs and mix again.
Chuck in the self raising flour and salt, then slowly add the milk while you mix (don’t over mix here).
Fold it all together, scraping down the sides, then chuck in the chocolate chips and fold through.
Spoon the mixture into your mini muffin tins. This makes about 24 mini muffins. Fill them up but don’t go all the way to the top.
Top with a few extra chocolate chips.
Pop them in the oven for 15–18 minutes, until golden brown and cooked in the centre.
