Notes: You can cook the potato and refrigerate it up to 5 days in advance.
Notes: You can use a food processor to make the brownie batter if you prefer.
Notes: For fudgy, gooey brownies, bake for 23 minutes. Brownies are best when baked to an internal temperature of 165°F for fudgy, and up to 180°F for more cake-like brownies.
Notes: The brownies will slice more cleanly once they are completely cool.
