Transfer your muffins to a cooling rack after cooling for five minutes in the pan after removing them from the oven. This will prevent tough or overcooked muffins.
Don't like chocolate chips? You can swap them for dried cranberries or raisins instead.
Use muffin liners or spray your pan well. Both of these options are ideal to prevent sticking.
Sprinkle some chocolate chips on top of the muffins right before baking if you want the chocolate chips more visible.
