Preheat oven to 350F or 180C.

Line a muffin pan with muffin liners.

Stir the flour, cocoa powder and baking powder together, set aside.

Cream the butter and sugar together, add vanilla and eggs one by one and mix after each.

Add the yogurt and mix until just combined.

Add the milk and flour mixture in sequence, start and finish with the flour mixture, DO NOT over mix or your muffins won’t rise as much. Add the chocolate chips and mix until just combined.

Fill the muffin liners with the batter and bake in the oven for 25 minutes. Check if they’re baked using a toothpick, if the toothpick comes out clean with little crumbles, then your muffins are ready.

Let cool for 10 minutes and then serve.
