Think of the basic fudgy brownie as the ultimate blank slate, endlessly customizable with nuts, chips, flavorings, and toppings. Our interactive recipe maker makes it easy: You choose mix-ins and toppings, from jam to orange zest to candies, and the recipe maker gives you a full recipe with exact amounts and instructions. Once you've built your recipe, you can share it with a friend, print it, or save it in our community recipe gallery.
