* Store cooled brownies in an airtight container in the refrigerator for up to 5 days.
* For an extra fudgy texture, refrigerate them before serving.
* You can use dark, semi-sweet or milk chocolate chips depending on how sweet you want them.
* The sweet potato should be drained very well after cooking. Excess water can make the brownies too soft.
* For the prettiest chocolate chip topping, add the chips **before baking**, just like we did for your batch.
* If you want an extra chocolatey finish, a tiny sprinkle of flaky salt on top after baking is absolutely welcome. 🍫
