Pre heat oven to 180 C and line muffin trays with liners.
In a bowl sieve in all purpose flour, cocoa powder, baking powder, baking soda, salt and give a quick stir to combine.
On another bowl crack eggs and beat with sugar. Then add yogurt, milk, oil, vanilla and mix to combine.
Next add wet to the dry and gently mix in everything making sure to scrape the bottom.
Now add some flour mix to chocolate chips and coat them. This will help chocolates to get evenly baked throughout all muffins.
Add in coated chocolate chips in the batter and fold in gently until mixed in.
Pour in batter in muffin liners. I like to use an ice cream scoop for that. Bake for 15-18 minutes.
