Tip the flour, cocoa powder, baking powder and sugar into a large bowl with a small pinch of salt. Add the eggs and whisk until smooth. Gradually whisk in the milk until you have a smooth batter, then mix in the chocolate chips. Heat a splash of the oil and a little of the butter in a non-stick frying pan until sizzling. Cook the pancakes, using 2 tbsp batter for each, for 2 mins until bubbles start to form on the surface. Flip and cook for 2 mins more (you'll need to do this in batches).
