Sadly, all the single-serving recipes are true single servings which means they don't really translate when multiplied out. If you want a full pan of brownies, try the Fudgey brownies (p. 207 HHC ) and if you want a full pan of pumpkin muffins, try the maple muffins (p. 46 HHC ). I also have a recipe for a full pan of blueberry muffins and a pan of fruit crisp on this blog... so basically, all my single serving recipes have a full serving cousin!
