In a second bowl, mix all the wet ingredients using a wooden spoon.
Incorporate the dry ingredients to the wet ingredients at once using a wooden spoon. Do not mix too much. Add the chocolate chips (or any other fillings such as raisins, frozen cranberries, etc.) at this step.
Pour the preparation into the muffin mold.
