Which of the following is included in the toppings for pancakes?

Chocolate chips are a popular topping for pancakes, enhancing their flavor with a sweet, rich taste that many diners enjoy. They melt slightly when added to warm pancakes, creating a delightful treat that's particularly appealing, especially in breakfast settings.

Other toppings like peaches, raisins, and coconut may also be used for pancakes, but chocolate chips are particularly common in diners, especially as a dessert-like option. Their popularity and the fact that they complement the fluffy texture of pancakes well make them a standard choice in many menu offerings. This makes chocolate chips the most fitting answer in the context of common pancake toppings served in diners.
